BOPT, Vertical preparation, feather-edge, edgeless preparationAbstract
The abutment tooth preparations for fixed prosthesis can be tried by a variety of methods, with the most common being the specified margin preparation and the vertical preparation or feather edge preparation. The second one was first utilised for prosthesis on abutment teeth that had periodontal disease and had been treated with resective surgery. In vertical preparation, we can alter gingival tissues to our desired contours using a rigorous, phased approach that includes preparation, provisionalization, and final prosthesis. The technique of vertical preparation in which finish line is absent, is a method in which the abutments are prepared by using a diamond rotary instrument into the sulcus to remove the existing cement-enamel junction and to make a new prosthetic cement-enamel junction controlled by the margin of the prosthesis.
