Accuracy of Robotic Computer-Assisted Implant Surgery Combined With Transcrestal Sinus Floor Elevation for Single-Tooth Implants: A Retrospective Case Series.

ABSTRACT:

Aim

To evaluate the accuracy and safety of robotic computer-assisted implant surgery (r-CAIS) for transcrestal sinus floor elevation (TSFE) in single-tooth implant placement.

Materials and methods

In this retrospective case series, we assessed the positional accuracy of r-CAIS combined with TSFE in the posterior maxilla. Preoperative and postoperative cone-beam computed tomography (CBCT) scans were used to determine implant positioning accuracy. Subgroup analyses evaluated the effects of various factors on accuracy. Additionally, complications were recorded and evaluated.

Results

A total of 40 patients and 40 implants were included. Only one case (Case XIX) exhibited a Schneiderian membrane perforation, resulting in a perforation rate of 2.5% (1/40). The mean global c
