Abstract:

Background: The aim of this study was to evaluate the accuracy of implant placement using static guide surgery. Two methods of were compared: Implant placement in native bone and in post-extraction site.
Methods: 47 implants were placed with static surgical template using a flapless technique. Patients were divided into two groups: Group 1 was made by 29 implants placed in extraction socket while group 2 was made by 18 implants placed in native bone. Accuracy of implant placement was evaluated by CBCT superimposition protocol.
Results: The study showed differences between two methods of implant placement in two parameters considered. The average real deviation detected at the implant platform level is 1.00 ± 0.91 mm for post-extraction site and 0.49 ± 0.48 mm for native bone (P=0.01). The average angular deviation detected at implant level is 21.94° ± 36.80° for post-extraction sites and 12.80° ± 11.71° for native bone (P=0.006).
There were not statistically differences between two methods for 7 parameters left.
Conclusion: The present study showed that implant placement in native bone is more accurate than in post-extraction sites using a static surgical template.
