Registration Number
NCT03730506
Lead Sponsor
Cairo University
Brief Summary

Assessment of the Accuracy of Surgical Guide Designed from Digital Impression, Dental Model Scanning using CBCT and Desktop Scanner in Computer Guided Implantology:

Randomized Clinical Trial.

Detailed Description

Research question:

In computer guided Implantology, are surgical stents designed from scan of dental model by CBCT and from digital impression as accurate as surgical stents designed from desktop scanner?

Statement of the problem:

The role digital dentistry is improved in computer guided implantology especially with development of computer guided implant software, desktop scanner and intra oral scanner development and CBCT machines.

Intra-oral scanner, desktop scanner and CBCT scanner can be used in creation of 3D digital model that can be used with computer guided implant in fabrication of the surgical stent.

And the question, is the accuracy of surgical guide will be affected when designed by one of these different modalities?

Rationale for conducting the research:

Digital 3D dentoginival details are very important in computer guided implantology and designing of surgical stent.nowadays there are many methods to obtain this soft tissue replica as CBCT,desktop scanner and intra oral scanner.this study is conducted to asses the effect of different method of soft tissue digitization on the accuracy of surgical template used in computer guided implantology.
