Overview
Brief Summary
To compare the static computer-aided implant surgery (s-CAIS) and conventional laboratory-guided implant surgery (c-LIS) in terms of accuracy for single tooth replacement in posterior areas.
Detailed Description
There was still a lack of evidence in randomized clinical studies about the accuracy measurement comparing digital and laboratory workflows with tooth-supported templates for single implant cases in the posterior regions. Therefore, this present study's primary investigation was to perform accuracy measurement comparing digital and laboratory workflows with tooth-supported templates for single implant cases in the posterior regions. The secondary investigation was to find the effect of several factors on the accuracy of implant placement in these areas.

Eligibility Criteria
Inclusion Criteria

Outcomes
Primary Outcomes
The accuracy of implant placement
Time Frame: Three months after implant placement
Patients were called back to record the actual implant position with the the intraoral scanner (Trios 3, 3Shape, Copenhagen, Denmark). The surface scans were then exported as an STL file and were imported to coDiagnostiX software. Those postoperative surface scans were merged with the preoperative surface scan in each group protocols. The "Treatment evaluation tool" function tool was used to measure the accuracy of the implant placement which measured the amount of deviation of the placed implant from the planned position. The outcomes were generated into three main parameters which were Angular deviation, Coronal global deviation and Apical global deviation. Angular deviation = the amount of angle(°), in which the actually placed implant deviated from the virtually planned implant in 3D. Coronal/ Apical global deviation = the amount of distance(mm), in which the actually placed implant deviated from the virtually planned implant at the coronal/ apical position in 3D.
