Optical accuracy assessment of fully guided Yomi implant surgery in partially edentulous cases

Dental implant placement can be guided by static or dynamic forms of computer-assisted implant surgery (CAIS). Previous studies have analyzed the accuracy of computer-assisted implant surgery through using both pre-operative and post-operative CBCT scans to compare deviations. This study introduces a new method of intraoral scanning to evaluate the accuracy of implant positioning. The objective was to design a reproducible and quantifiable method for evaluating implant placement with the Neocis Yomi system using a radiation-free postoperative intraoral scan and an industrial Computer Assisted Inspection software (Geomagic Control X). In this cohort of a pilot study comparing virtual planned position versus actual position, the global position and angulation of the implant were referenced indirectly with the use of a scan body. Twelve (12) fully guided implant samples were evaluated from eight (8) patients. The mean positional deviation at the top of the scan bodies was 1.3389 mm. The mean positional deviation at the implant restorative platform was 1.4063 mm. The mean positional deviation at the implant apex was 1.6684 mm. The mean angular deviation was 2.8415°. The results confirm that the Yomi surgical robot by Neocis is a comparatively accurate tool for guided implant placement. The measure of inaccuracies and deviations was similar to those found in analyses for other methods of computer-assisted implant surgery and other cohorts of this protocol.
