Evaluate a Saw Bone Training Protocol in Using Tactile Sensation to Classify Bone Quality During Implant Surgery

• Conditions: Diagnosis of Bone Quality; Training Tactile Sensation; Surgery

• Registration Number: NCT03307798
• Lead Sponsor: National Taiwan University Hospital

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.

Detailed Description

Twenty-five dentists will be enrolled into the study. Tests will be performed using visual analog scale to score bone quality of test blocks.
