Onlay Preparation:

Now I introduced the onlay preparation in China dental lab, if any questions, please contact me. Avoid aciculate centralized band angles and undercuts. With onlays, cuspal abridgement of a minimum of 1.5 mm is required. Smooth basic walls and trim balance lining actual with finishing design or dentures. Do not cover undercuts. Create a 5o to 15o alteration in the adjacent walls from the attic to the occlusal allowance of the preparation. Ensure all walls end in a base dental margin.
