Freehand versus computer-guided implant placement: early implant failures in a case-control study

Objective: To evaluate the survival of fully guided implants placed with a hollow tooth-supported computerized surgical guide (TSSG). Method and materials: This retrospective study included 94 patients who underwent implant placement using freehand or TSSG by the same operator between 2015 and 2020. Early implant failures occurring within 1year postrehabilitation were assessed. Results: In the study, two types of implants were placedusing two different techniques: TSS Gandfreehand. The TSSG group consisted of 84 S implants and 100 LP implants, and the freehand group included 90 S implants and 94 LP implants. The results showed that more implants survived when placed freehand compared to TSSG (181 [98.4%] vs 172 [93.5%], respectively, P<.05).Theonlysignificantfactoraffectingthesuccessratewasthetypeofimplant,withLPimplants having a higher survival rate in the TSSG group (P<.05). Conclusion: Surgeons should consider the impact of implant type on survival rates when utilizing the TSSG system.
