• The Fit Accuracy of a Pure Titanium Crown Fabricated with a CAD/CAM System.

抄録

Purpose: This study showed a pure titanium crown, of which the adaptation accuracy is high using a CAD/CAM system (Dental Cadim), which was fabricated for this procedure. The purpose of this is to show the fit accuracy of the crown produced on the abutment tooth. The model showed several kinds of axial surface taper.<BR>Method: The pure titanium crown inner surface fabricated by CAD/CAM systems is cemented with white silicone and pressed with 20kgf of pressure. As to the thickness of the silicone, it was measured 3 times at each and every place. The mean value was observed, and the significance test was done between tapers at each measuring place.<BR>Results: 1. The crown fabricated from abutment tooth model of tapers of 2° and 4° greatly rised. 2. The marginal distance between crown and abutment tooth model of taper 8°(30-50μm) is smaller than taper 6°. 3. The taper 6° is the gap between the crown inner surface and abutment tooth model and it showed very large value but the taper 8° is all measuring part places of small value. The distance between crown and abutment tooth model of taper 8° has 70μm clearance.<BR>Conclusions: To fabricate the pure titanium crown using value and method for setting CAD/CAM system (Dental Cadim) in this study it is required the abutment tooth axial surface be over taper 8°.
