Summary:To evaluate the survival of fully guided implants placed with a hollow tooth-supported computerized surgical guide (TSSG). This retrospective study included 94 patients who underwent implant placement using freehand (FH) or tooth-supported computerized surgical guide (TSSG) by the same operator between 2015 and 2020. Early implant failures occurring within one-year post-rehabilitation were assessed. In the study, two types of implants were placed using two different techniques: TSSG and FH. The TSSG group consisted of 84 S implants and 100 LP implants, while the FH group included 90 S implants and 94 LP implants. The results showed that more implants survived when placed FH compared to TSSG (181 (98.4%) vs 172 (93.5%) respectively, p < 0.05). The only significant factor affecting the success rate was the type of implant, with LP implants having a higher survival rate in the TSSG group (p < 0.05). Surgeons should consider the impact of implant type on survival rates when utilizing the TSSG system.
