Brief Summary
Bone quality is one of the major factors influencing the dental implant survival rate. Bone quality is believed to have effects on initial implant stability and success of osseointegration. Different implant designs and surgical protocols were developed for improving the survival rate in different bone quality. Although bone quality can be partly diagnosed by radiographic images, lots of experienced surgeons also evaluate bone quality with tactile sensation when they drill the bone. However, variations in evaluation of bone density maybe exist among different surgeons. For less experienced dentists, it is difficult to diagnose bone quality with tactile sensation in the beginning. This purpose of this study is to evaluate a training protocol in using tactile sensation to classify bone quality during implant surgery. Saw bones of variant densities are used as training materials. The outcomes before and after training will be compared. The effect of training frequency before surgery will also be evaluated.

Outcome Measures
Primary Outcomes (1)
Change on visual analog scale (VAS) score of each test block
Each VAS score performed on the specific test block will be compared between different time point.
1st time point: test before training & test immediately after training; 2nd time point: 1 week after 1st time point (test after 1 wk); 3rd time point: 1 month after 2nd time point (test after 1month)
