Popis: | The purpose of this study was to clarify the problem in case of removal of the titanium crown from the abutment tooth. The specimens in the shape of simplified full cast crown were produced with pure titanium and Ag-Pd alloy. The specimens were cut using dental turbine with carbide burr, which was used 12 consecutive times. The required time to cut the specimen was measured, and the difference of materials and thickness of specimens were evaluated. Furthermore, the section of burr that was used 12 consecutive times was observed.The results were as follows:1. The required time to cut the titanium crown was longer than that of the Ag-Pd alloy crown.2. In case of cutting the titanium crown, the damage to the carbide burr was extensive compared with Au-Ag-Pd alloy of the same thickness.From the above, it was suggested that a device for reducing the thickness of the crown was necessary to produce the titanium crown. |
