Introduction of Parallel Measurement and Supplementary Apparatus Newly Developed

Abstract

Prosthesis has a close relation with parallel. When installing prostheses, sometimes dentists need to reform abutment teeth or remaining teeth. In the case of partial denture, remaining teeth and its contours should be parallel. In the case of crown & bridge, abutment teeth and pins should be parallel. In the case of implant, success of the following prostheses depends on implant's direction. The ideal preparation is not easy even for skilled dentists, much less for students and beginners. If they use parallel measurements, they would save time and its accuracy gets higher. Therefore, we invented the parallel measurement apparatus which is convenient for clinical use.
