Abstract EN
The aim of this study was to evaluate the accuracy of a stereolithographic template, with sleeve structure incorporated into the design, for computer-guided dental implant insertion in partially edentulous patients.
Materials and Methods.
Sixty-five implants were placed in twenty-five consecutive patients with a stereolithographic surgical template.
After surgery, digital impression was taken and 3D inaccuracy of implants position at entry point, apex, and angle deviation was measured using an inspection tool software.
Mann–Whitney U test was used to compare accuracy between maxillary and mandibular surgical guides.
A p value < .05 was considered significant.
Results.
Mean (and standard deviation) of 3D error at the entry point was 0.798 mm (±0.52), at the implant apex it was 1.17 mm (±0.63), and mean angular deviation was 2.34 (±0.85).
A statistically significant reduced 3D error was observed at entry point p=.037, at implant apex p=.008, and also in angular deviation p=.030 in mandible when comparing to maxilla.
Conclusions.
The surgical template used has proved high accuracy for implant insertion.
Within the limitations of the present study, the protocol for comparing a digital file (treatment plan) with postinsertion digital impression may be considered a useful procedure for assessing surgical template accuracy, avoiding radiation exposure, during postoperative CBCT scanning.
