Minimally Invasive All-ceramic Preparation for the Occlusal Face: The "V Preparation".

A clinical case illustrates and explains step by step a minimally invasive molar occlusal surface preparation for all-ceramic bonded restoration. The sequential use of calibrated burs, following the specific procedure, systematically and quickly, provides a perfectly calibrated reduction of the occlusal face even for an inexperienced practitioner. This preparation increases the bonding surface and optimizes the accommodation of constraints that provides a more resistant reconstruction and favors the preservation of the vital tooth. This procedure, called a "V preparation" or V prep, is discussed in the case report below.
