an implant-related lawsuit
While implants can add another revenue stream to a practice, dental practitioners need to be aware of the associated risks, according to Burdick Ray, JD, an attorney in Irvine, CA, whose practice is focused on lawsuits involving dental implants.
During a presentation September 22 at the California Dental Association (CDA) fall session, Ray had plenty of advice for dentists who want to protect themselves.
For example, robust consent forms are essential, he emphasized.
"A good consent form will kill a lawsuit before it's filed," Ray said. It should completely cover the risks inherent to implant surgery, as well as the effects of post-treatment prescriptions. Infection, bleeding, sinus perforations, bone fractures, slow healing, and nonunion of the implant to the jaw, and permanent numbness should all be included as potential risk factors.

" 'Permanent' is a key word," he noted.
Potential complications associated with anesthesia also should be included.
"That includes death," Ray said. "It's purely legal, but true! It only makes sense to cover this possibility with general anesthesia."
Interestingly, not using a cone-beam CT scanner can be a possible area of exposure to lawsuits if an implant procedure goes awry.
"Failure to offer cone-beam CT in many cases may be considered substandard care," Ray said.
Cone-beam CT should be offered regardless of a patient's ability to pay, he added. If the patient turns it down, he recommends providing written informed refusal or documenting the refusal in the patient's chart.
Informed refusal is critical for the entire treatment plan, Ray stressed.
"You must explain the plan, regardless of the patient's ability to pay," he explained. "Then you can inform them of the risks of refusing treatment and list alternatives."
Having patients sign an informed refusal form or their chart adds another layer of protection, he said. Samples of these forms can be found at www.d-group-cn.com. In short, it should say, "Dr. ___ recommends this course of action." An option that states "refused to accept" with a signature line should appear at the bottom.
Having the patient sign the informed refusal form is a nondelegable task, Ray warned. The front office staff can handle financial agreements but not informed consent forms. And the forms aren't much use if they aren't filled out, he noted.
"People who get sued don't fill in their forms completely," Ray said.
Proper documentation
Ray also discussed the importance of maintaining proper documentation and how dental records can be used in a lawsuit. It may seem like common sense, but "never alter records," he said. If you need to, draw a single line through it -- to show you're not hiding anything -- write in your new notes, and sign or initial it. There's no other way to do it."
Aside from obvious ethical implications of masking notations made on medical records, it is virtually impossible to fool the specialists that examine documents, according to Ray. He outlined a host of technologies and methods that are at the disposal of document examiners.
"Forensic experts -- don't mess with them," he said.
Case studies
To drive home his advice, Ray presented two case studies. In the first, a 46-year-old patient who was a friend of the dentist had a single implant replaced on an old three-unit dental bridge. The dentist positioned a 16-mm Sargon implant well into the inferior alveolar nerve canal. The error was not diagnosed for 15 months.
"When the dentist took x-rays, he thought, 'I'm not in the canal' and repeated the error, based on the appearance of the x-rays," Ray explained.
The proper diagnosis was finally made after 3D imaging was used, but the implant could not be removed due to flaring. The case was settled out of court.
"Order a cone-beam CT scan, or offer one," Ray urged. "Or at a least a Panorex. And get a cone-beam CT immediately once an altered sensation is reported."
The second case involved a 57-year-old musician who did not speak English. Weeks after an extraction, a panoramic image was taken; several days later, an dental implant was placed. The same process was repeated on the other side of the patient's mouth, but in this instance the dentist skipped the panoramic image. In addition, he used the same implant and did not remeasure. Subsequently, the patient reported numbness.
"The negligence was in mismeasuring," Ray said. "It's the earlier drilling that usually does the damage before the implant is even placed."
The dentist made several other mistakes, he added:
There was no witness to the signed consent form, which was not in the patient's language.
The treatment plan was also unsigned.
The dentist did not explain the risk of numbness to a musician whose mouth was crucial to playing an instrument that was the source of his livelihood.
While many practitioners are hesitant to get a second opinion from another doctor, getting one also can protect you, Ray noted.
"Don't let pride get in your way," he advised. "An oral surgeon is a good backup."

Dental Implant
September 21, 2011 - Sescoi will be exhibiting its automatic WorkNC Dental CADCAM software at two major European dental exhibitions, in collaboration with Willemin Macodel CNC machines, at ARIA CAD-CAM Dentaire in Lyon, France 23-24th September and International Expodental 6-8th October in Rome, pavilion 7, stands B30+C29.
At both shows, Sescoi dental engineers will be demonstrating the latest developments in the WorkNC Dental open Implant dental and Automation Modules. With the Implantology Module, WorkNC Dental can acquire the 3D orientation and location of each implant, and the digitized geometry of bridges and crowns from a range of scanners and dental CAD systems, allowing dental professionals to choose the most appropriate equipment for their laboratory. It then automatically generates CNC cutterpaths tailored to suit the individual machine tool and prosthetic material, making it easy for dental technicians to produce highly accurate prostheses without specialist CNC machining experience. The Automation Module goes a stage further and manages the whole production process, controlling the job loading and unloading, selecting which machine to use, automatic starting and stopping of machining operations, and error reporting.
Visitors to the two shows will be able to see live cutting on a Willemin Macodel 408MT machining center. Dental laboratories will be able to evaluate how easy it is to produce bridges and crowns for implants and machine them from bars, discs, blanks or plates in a wide range of materials such as zirconia, titanium, cobalt chrome, PPMA and lithium disilicate, using this combination of machine and software to optimize the process. The WorkNC Dental Automation Module will be used to queue jobs for production, transfer the program to the machine control, operate the bar feeder, and start and stop machining operations, allowing technicians to spend more time on their core skills rather than on managing the manufacturing process.
Sescoi’s open dental CADCAM system is able to offer an integrated solution to dental lab which fully automates the machining of prosthetic implants from bar and completely manages the production process. The pairing of machine and software delivers valuable productivity enhancements coupled with high levels of flexibility, which will enable an innovative approach to dentistry that benefits the industry and patient alike.

Dental Procedure Gives Patients Implants in One Day
Corn on the cob is just one of the many foods that is hard to eat if you wear dentures.
Jim Artress, 67, who lives in New Jersey, struggled with his dentures for 10 years while searching for a better alternative.
“It's kind of embarrassing if you're eating with someone, and it's obvious that your compensating for teeth that are not secured to your mouth," Artress said.
After spending thousands of dollars on consultations and estimates for dental implants, he still was not convinced.
Then he heard about another type of dental implant at the Malo Clinic in Rutherford, N.J.
“It just made sense, and they said they could do it in one day, and I would have the teeth,” he said.
Artress’ oral surgeon, Dr. Steven Moss, said with other procedures, patients may have to undergo expensive bone grafting for more than a year to prepare for implants.
"So what we used to do in 12, 15, 18 months—we can now do in one day," Moss said.
Normally, once someone has lost their teeth, they don't have enough bone remaining in their jaw for implants.
However, using the latest 3D imaging technology—the "all on four" technique—it takes as little as four hours to put a bridge on just four implants, which are angled to utilize the bone that is available.
And the procedure is covered by most dental insurances.
So for patients like Artress, living with dentures doesn't have to be the only solution.
“Many patients are told they have no alternatives; they are stuck with their dentures and that's why we have advertisements saying ‘no, you're not stuck with your dentures,’” Moss said. “There is an alternative, there is hope.”

Dental students use iPads to improve patient interactions
Students are using iPads equipped with a special application that gives them a new way to communicate with patients, discuss oral health topics and dental
procedures, and educate patients about the health of their mouths.
Since spring quarter 2011, class of 2013 dental students have been working with various forms of digital technology to practice patient communication skills. In a preclinical
setting this spring, students conducted practice interactions with patients while being filmed with Flip video cameras, and faculty provided feedback and communication
coaching.
Now that the class of 2013 has transitioned into the clinic, students are utilizing the communication skills they previously learned to conduct more effective and positive
interactions with patients, with the help of an iPad.
In the clinic, the students use iPads equipped with the DDS General Practitioner application. The app allows students to easily show photos, diagrams, and animated images of
common oral conditions and dental implant procedures. It also allows students to
present clinical findings, prevention recommendations, and hypothetical treatment plan options.
"This project has enhanced the student's ability to impart prevention and treatment plan options, and has fostered better patient communication," stated Chris Miller,
director of community programs, co-director of the Pacific Center for Special Care, and one of the pilot project's faculty leaders, in a news release. "Already students using
the iPads have been witness to the impact a strong visual aid can have on their patients."
The innovative pilot project was spearheaded by Miller along with Maria Murtagh, director of the Student Store, and Raybel Ramos, director of the information technology
department.
Funds used to purchase the iPads came from a generous donation from a school supporter, Louisa Galdieri. Pending a successful pilot year, the program will be looking for
other sources of funding to continue and expand the use of iPads in the clinic.
"One of the Dugoni School of Dentistry's goals is to harness technology to maximize learning," Miller said. "Bringing iPads into our clinic is doing just that."

Zahnersatz aus China
Natürlich kann man nicht jeden Zahnersatz
aus China über einen Kammscheren,es gibt auch
da teilweise große qualitative Unterschiede.
Die Erfahrungen der einsetzenden Zahnärzte
jedoch sind sehr häufig nicht zufriedenstellend.
In vielen Fällen treten die ersten Probleme
bereits beim Einsetzen der Zähne auf.
Die Passgenauigkeit ist trotz der eingeschickten Abdrücke nicht
immer gewährleistet.In Deutschland würde man solch ungenau
gearbeitete Zähne kurzerhand zurückschicken.Andere Schwierigkeiten
kommen nicht selten erst nach erfolgreichem Einsetzen auf.
Manchmal brechen Zahnstückchen nach nicht allzu langer Tragedauer
ab oder es treten Schmerzen auf,da die Zähne nach einiger Zeit minimal
ihre Form verändern können.In solchen Fällen muss wieder neuer Zahnersatz
angefertigt werden und die lästige Prozedur des Einsetzens beginnt von vorne.
Natürlich greifen die enttäuschten Zahnersatz-Patienten in der Regel nicht
wiederholt zu den Discount Zähnen.Nach einer solchen schlechten Erfahrung
beißen sie sprichwörtlich in den sauren Apfel und entscheiden sich doch für
professionell aber leider teuer in Deutschland hergestellte Zahnimplantate.
Es gibt allerdings auch Erfahrungsberichte von Patienten,die absolut nur
positive Erfahrungen mit Zahnersatz aus China gesammelt haben.Diese würden
die Implantate verständlicherweise jedem,der mit dem Gedanken spielt,einen
vom Zahnarzt erstellten Abdruck in ein Zahnlabor nach China zu schicken,nur
weiterempfehlen. Es stellt sich also die Frage, ob der Zahnersatz aus Fernost
eine wirkliche Alternative zu deutschen Erzeugnissen darstellt,oder ob man am
schließlich nicht vielleicht doch am falschen Ende gespart hat und möglicherweise
zum Schluss ein vielfaches drauflegen muss, um den Schaden wieder auszubügeln?
Fazit: Bei den momentanen Qualitätsproblemen von chinesischem Zahnersatz sollte
jeder, der es sich leisten kann,vorsichtshalber zu den teureren heimischen
Produkten greifen. Einen Versuch kann man aber auf alle Fälle wagen
- einige gute Erfahrungen sprechen dafür.

Dental problems: Treatment And Preventive
" Some tortures are physical,
Some tortures are mental,
But the one that is both is Dental!"
Dental troubles are of two types: cavities and gum diseases. Many people put off going to dentists for fear of pain and cost of the procedures. But this can lead to bigger dental problems and more expensive treatment in the future. When it comes to dental issues, it is always better to be safe than sorry.
Most common dental problems are cavities. Cavities always start with tiny holes caused by acids and sugars in food. The patient might not feel any pain during the early stages of these problems. But as the cavity gets deeper, they might experience sensitivity to hot and cold foods. The cavity might even progress to the stage where the tooth has to be extracted or treated with Root canal Therapy.
What is Root Canal Therapy?
Root canals are small capillaries in the root of the tooth. These capillaries get infected due to the bacteria in the food. The patient experiences sharp pain due to this. With antibiotics, the infection may be cured up to an extent, but eventually a root Canal treatment may be required. In root canal treatment, the dentist drills the tooth, removes the infected pulp of the tooth and drills the nerve with needle-like drills. After this is done, the canals are sealed with inert material. The tooth naturally gets weakened due to this procedure, hence a crown becomes mandatory.Permanent crowns may be metallic, PFM or all-ceramic types.
Gum disease (Pyorrhea) is a” silent killer” of teeth. 95 percent people in their twenties suffer from it, but they do not realize it until their forties, at a stage where the disease is quite advanced. Pyorrhea is caused by tartar on teeth and the common symptoms are bleeding or pus filled gums and bad breath.
Regular cleaning done by professionals is a good way of ensuring healthy gums and teeth. Along with this, regular brushing, flossing after meals and using antibacterial mouthwashes are some preventive measures one can take to avoid dental problems. Some foods that are naturally good for the teeth are: strawberries, apples, celery etc. Also drinking a lot of water ensures that healthy saliva is produced, teeth are hydrated and food particles are washed away.When it comes to teeth:prevention is the best cure..
Dental Endangered by Severe Periodontal
Researchers kept track of the people in the study for as long as 12 years after they received their implants. Only 4% of the implants failed. A failed implant does not bond with the jawbone. It must be removed.
For the first four years after implant placement periodontal disease had no impact on the retention of an implant in the jaw bone. After about four years, people with severe periodontal disease had eight times the risk of having their implants fail. Smokers had about three times the risk of failure.
The authors believe that the failure rate increased after four years because periodontal disease gradually worsens if it is not treated. As a person's periodontal disease becomes worse, the bone and gum tissue around the implant is harmed. This continues until the implant cannot work anymore.
People with moderate or mild periodontal disease did not have a higher risk of implant failure than people with healthy gums.
Periodontal disease affects the gums and other supporting structures of the teeth. In advanced periodontal disease, the gums pull away from the teeth and fibers and bone that support the teeth start to break down.

Common Cosmetic Dentistry options
Cosmetic dentistry may involve: 1. the addition of a dental material to teeth or gums - examples: bonding, porcelain veneers (laminates), crowns (caps), gum grafts 2. the removal of tooth structure or gums - examples: enameloplasty etc., gingivectomy 3. neither adding nor removing dental materials, tooth structure or gums - examples: teeth whitening (bleaching). 4. straightening of teeth accompanied by improvement in appearance of face Orthodontics
Tooth bleaching is the most common cosmetic dental procedure. While many whitening options are now available, including over the counter products, dentist-supervised treatments remain the recommended procedures for lightening discolored teeth.
Bonding is a process in which an enamel-like dental composite material is applied to a tooth's surface, sculpted into shape, hardened and then polished.
Dental bridges are false teeth, known as a pontics, which are fused between two porcelain crowns to fill in the area left by a missing tooth. The two crowns holding it in place that are attached onto your teeth on each side of the false tooth. This is known as a fixed bridge. This procedure is used to replace one or more missing teeth. Fixed bridges cannot be taken out of your mouth as you might do with removable partial dentures. In areas of your mouth that are under less stress, such as your front teeth, a cantilever bridge may be used. Cantilever bridges are used when there are teeth on only one side of the open space. Bridges can reduce your risk of gum disease, help correct some bite issues and even improve your speech. Bridges require your commitment to serious oral hygiene, but will last as many as ten years or more.
Veneers are ultra-thin, custom-made porcelain laminates that are bonded directly to the teeth. They are an option for closing gaps or disguising discolored teeth that do not respond well to whitening procedures. Depending on the procedure, tooth reduction may be necessary.

Plastic dentures hit the dentistry market l
Dens3000 teeth, which the company says closely resemble natural human teeth in shape and structure, are made by injection moulding biocompatible and monomer-free "Densomid" modified PMMA plastic layers - comprising a core material and an outer "enamel" layer - of different hardness and colour.
According to patents covering the artificial tooth design, the core material can be a thermoplastic filled with siliceous glass, quartz and hydroxylapatite, as well as injection-mouldable polymer-bound ceramics. Dens3000 says that as the thermoplastic tooth comes directly out of the injection mould and does not require further working, it is "highly cost-effective", costing five to ten times less than artificial teeth produced by the conventional thermosetting plastic ram extrusion method.
The 0.1-0.73g teeth are moulded with 2.5-5.6g shot weights in four 8-cavity moulds, in a cycle time of 22-30 seconds. A full denture set has 28 teeth chosen from 144 samples in 16 different shades, three sizes and various shapes. The original developer, medical physicist Dr Reinhard Lohse, says: "I wanted to introduce a high-quality yet inexpensive plastic tooth onto the market and so make dentures that appeal to China and eastern European countries, where cost is an important issue."
Aside from cost benefits, Lohse says the PMMA teeth "are also not prone to plaque or crack formation". Dens3000 teeth have a useful life of around five to ten years. Design features include a "finger", modelled on the human tooth root that stabilises the denture base, while an external palatal/lingual slot at the tooth base and a "retention bore", with integrated undercut, strengthen the denture base to "previously unattainable levels", he says.
Lohse further developed the tooth in partnership with the IWK materials technology and plastics processing institute at Kaiserslautern University, and the Regensburg and Homburg (Saar) university hospitals. After developing production tools and prototypes, Lohse set up the Dens3000 company in 2006. The teeth are injection moulded on four electric-drive 150-tonne clamp-ing force Arburg Allrounder 520A machines, each equipped with two size 70 injection units. Earlier this year, Arburg said Dens3000 is expected to "shortly" reach full production capacity of 20 million teeth per year.
Dens3000 is also setting up a production site in China, according to the Protonia-IT foundation. Initial Chinese production is ex-pected to amount to around 40 million teeth per year, with start-up scheduled for October 2011. The project contract is being managed by the DCTA German-Chinese technology exchange foundation. Plastic materials are also making inroads in dental implants. Here, NT_Trading is using medical grade Vestakeep I PEEK from Evonik to make Dentokeep semi-finished implants, substituting titanium and cobalt-chromium metals. The material provides high implant elasticity and a similar flexing behaviour as bone, making the implants more comfortable for the patient.
Marc Knebel, medical implants sales and marketing manager at Evonik, says injection moulding already substitutes machined semi-finished parts when volumes are sufficiently high, cutting implant production costs. Knebel adds that since 1999 PEEK has become the most important substitute material for titanium in orthopaedic, cardiovascular and spinal implants, a trend partly driven by the material's high resistance to gamma rays, transparency to x-rays and biocompatibility.
Dentures Benefits
Dentures are removable dental appliances that are used to replace missing teeth. Dentures can be fabricated to replace a full set of missing upper and lower teeth, or just a few missing teeth. Because they improve the appearance of patients' smiles and restore chewing function, dentures offer many benefits to patients and can significantly enhance their quality of life.
Cosmetic Benefits The cosmetic benefits of dentures are obvious. They fill in gaps left by missing teeth so patients feel more confident about their appearance. The aesthetic advantages of dentures include: -Replaces missing teeth or teeth that were in poor condition
-Prevents further shifting of remaining teeth
-Avoids embarrassment when smiling
-Supports facial structure and integrity
-Supports facial muscles
-Functional Benefits
Dentures offer a range of functional benefits to patients. The functional advantages of dentures include: Allows patients to eat the foods they want Improves speech (after patients get used to wearing dentures) Typically lasts between five and 10 years (with proper care) Price
Dentures tend to be the least costly solution for replacing missing teeth. Alternative treatment options such as dental bridges or implants are generally more expensive and require more extensive treatment. However, dental bridges and implants do offer a better fit, increased comfort, better chewing ability, and a more natural appearance. For these reasons, dentures-wearers may want to ask their dentists about these alternative treatment options. Your dentist can let you know if you are a good candidate for dentures, dental bridges, or implants, and let you know the cost of these options.

Survey: 35% of Americans cut back on dental visits
September 1, 2011 -- In the past year, more than one-third of people in the U.S. who regularly visit the dentist have cut back, according to a recent public opinion survey commissioned by Oral Health America.
The survey also found that a greater number (47%) of larger households and those with younger children have cut back on their visits to the dentist in the past year.
These findings are one of the many reasons why OHA has launched its second annual Fall for Smiles campaign, the organization announced. The campaign aims to remind policymakers and the public about the importance of dental self-care, regular dental visits, healthy food choices, and avoiding tobacco products.
Fall for Smiles runs through the end of October. Dental offices, health educators, school dental program officials, parents, and others can find tools to promote healthy mouths, including a social media guide, coloring sheets.
The Fall for Smiles survey, sponsored by Oral Healthcare Can't Wait and Plackers, was conducted online within the U.S. by Harris Interactive in June 2011.

Zirconium dental crowns
The Strongest
BruxZir™ Solid Zirconia is a full-contour solid zirconia crown or bridge with no porcelain overlay. More brawn than beauty, BruxZir is a great alternative to full metal crowns on back molars. Virtually chip-proof, these crowns and bridges are the ideal restoration for bruxers and grinders, implant crowns and areas with a tight bite.
Designed and milled using computer aided design and modeling (CAD/CAM) technology, BruxZir is heated for 6-10 hours at 1,530 degrees Celsius. The final crown or bridge emerges nearly “bulletproof” and is glazed to a smooth surface. BruxZir Solid Zirconia crowns and bridges are backed by a seven-year replacement warranty.
Strength and Beauty
Lava™ crowns combine the esthetics our patients demand with the strength they need. Lab tests have shown that the fracture toughness and flexural strength of Lava™ crowns are significantly higher than any other all-ceramic restorations. There is no metal to show through the ceramic, and no unsightly black lines at the edges.
This esthetic restoration is built on a foundation of the same zirconium used in the BruxZir crowns using CAD/CAM technology, which gives the final restoration a superb fit, and porcelain, which gives beautiful, translucent opalescence. After heating the foundation for ten hours to establish strength and fracture resistance, the framework is layered with the most esthetically pleasing porcelain material. The final restoration demonstrates exceptional marginal fit, tooth-like translucency and long-term durability. These crowns and bridges are touted as one of the most attractive and clinically proven all-ceramic restorations available today.
Is Gold Obsolete?
Even at over $1,800 an ounce, gold crowns are still necessary at times, depending on the bite, size and shape of the remaining tooth and esthetic demands of the area. Because gold is malleable and softer than zirconium, it may be gentler on the bite. In some cases, we would rather the gold wear out than damage the jaw joint. We usually reserve gold for the last molars in the mouth where they are hidden and the forces are much greater.
But whereas gold was once the only real long-lasting option for crowns, thanks to zirconium, patients can now opt for a durable, non-allergenic and attractive crown that looks much like their natural teeth.
man dies of dental diease
In an especially shameful episode that highlights the plight of those in the U.S. without medical insurance, a 24-year-old father has died from a wisdom tooth infection. Unable to afford both pain killers and antibiotics, Kyle Willis of Cincinnati, Ohio died after the infection spread.
LOS ANGELES, CA (Catholic Online) - "He [Willis] might as well have been living in 1927," Dr. Jim Jirjis, director of general internal medicine at Vanderbilt University said. "All of the advances we've made in medicine today and are proud of, for people who don't have coverage, you might as well never have developed those."
Jirjis says that people like Willis, without access to care often dies of conditions that were much more common decades ago.
Prior to his death, dentists told Willis his infected wisdom tooth needed to be pulled. Willis decided to forgo the procedure, because he was unemployed and had no health insurance.
When his face started to swell and his head began to ache, Willis went to the emergency room, where he received prescriptions for antibiotics and pain medications. Willis couldn't afford both, so he chose the pain medications. The infection spread, causing his brain to swell - he died last week.
"People don't realize that dental disease can cause serious illness," Dr. Irvin Silverstein, a dentist at the University of California at San Diego says. "The problems are not just cosmetic. Many people die from dental disease."Tragically, Willis' story is not unique. In 2007, 12-year-old Deamonte Driver also died when a tooth infection spread to his brain. The Maryland boy underwent two operations and six weeks of hospital care, totaling $250,000. Doctors said a routine $80 tooth extraction could have saved his life.
Deamonte's family was uninsured and had recently lost its Medicaid benefits, preventing the boy from having dental surgery.
"When people are unemployed or don't have insurance, where do they go? What do they do?" Silverstein said. "People end up dying, and these are the most treatable, preventable diseases in the world."
The Kaiser Family Foundation reported earlier this year said that 33 percent of people surveyed skipped dental care or dental checkups because they couldn't afford them. A 2003 report by the U.S. Surgeon General found that 108 million Americans had no dental insurance, nearly 2.5 times the number who had no health insurance.
