Monolithic zirconia restorations are popular but removing these crowns is difficult. The purpose of the study is to measure and compare the cutting effectiveness of 10 types of diamond burs through monolithic sintered zirconia. Ten types of diamond burs (n=8) were compared for the cutting effectiveness in Zirconia (CERCON; DeguDent) using a high speed computer controlled cutting device with water spray (5.45L/min). The turbine used to cut the blocks rotated at 150,000 rpm and with the burs at a depth of 2mm into the zirconia during cutting. A 100 gm load was applied during cutting for each bur which made …

Purpose: The influence of the vertical abutment positions on the retention of a three-unit implant supported cantilevered FPD restoration was measured and compared. Methods: The study included four groups (n=10) of cantilevered FPDs restorations, fabricated of monolithic zirconia. Prefabricated titanium implant abutments were used and connected to their analogs. The analogs were fixated on a split mold and their vertical position was adjusted on a 2 mm bases depending on the group, resulting also to an alteration of the occlusal thickness of the restorative material. The prosthesis were cemented to the abutments with Rely X Luting Plus resin modified glass …
