Objectives: Guided implant surgery requires osteotomy preparation through a stereolithographic surgical guide allowing a more precise placement of an implant compared to conventional non-guided protocol. However, the stereolithographic guide can hinder the cooling of the drill through irrigation. This study aimed at evaluating and comparing the implant survival rate using computer-guided and conventional non-guided surgical protocols. This study hypothesized that implant surgical failures/complications might be higher using the guided surgery protocol.

Methods: In this study, 100 consecutive implant placements using guided surgical protocol compared to 100 consecutive implant placements using conventional protocol were examined, from August 2016 to December 2017. All implant surgeries were performed in the university implant clinic. All implants in both surgical protocols were not loaded. The majority of implants placed using guided surgery protocol were performed using a flapless surgical technique, while all implants placed using the conventional non-guided surgical protocol were performed using a conventional flapped surgical technique. Implant survival after surgery was documented.

Results: There was no statistical significant difference between the two surgical protocols. Both protocols showed approximately 95% implant survival. However, more implants in conventional non-guided surgical protocol were later deemed unrestorable and required removal and replacement.

Conclusions: With a careful surgical protocol, guided implant surgery does not increase surgical failures or complications. Therefore, guided implant surgery should be considered when it is possible to facilitate both implant placement and definitive prosthetic fabrication.
