The Accuracy of s-CAIS Compared With c-LIS

The Accuracy of Static Computer-aided Implant Surgery Compared With Conventional Laboratory-guided Implant Surgery for Single-tooth Replacement: A Randomized Controlled Trial

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.

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.

Inclusion Criteria:

• Patients had a partially edentulous ridge in the premolar-molar region with existing two-sided interproximal as well as antagonistic contacts
• Patients had healthy periodontal status and adequate keratinized gingiva at the edentulous space

Exclusion Criteria:

• - Patients have any local and systemic diseases considered as contraindications for dental implant treatment.
