ABSTRACT
Objective: The objective of the present study is to evaluate the accuracy of static Computer-Assisted Implant Surgery (sCAIS) in single tooth implant placement by using formula method.
Materials and Methods: Total of 10 patients with one missing posterior tooth (unilaterally or bilaterally) in maxilla or mandible were selected for guided implant surgery. After implant placement, measurements between planned implant, achieved implant and reference anatomical landmarks on radiographs and images of planning software were noted and evaluated the accuracy by using formula method.
Results: The results of present study showed that mean measurement deviation of 0.35 mm at the implant crest and 1.03 mm at the implant apex, and angular deviation of 1.3°. The results showed greater accuracy in terms of the mean values of positional deviations. The main difference was at the apex (p value = 0.03mm) and least difference in crestal position (p value = 0.21mm).
Conclusions: It was found that guided implant surgery by using sCAIS is as accurate as planned and therefore, within the limitations, present study recommends digital guided implant surgery for single implant placement with high accuracy.
