Objectives: The aim of this study was to compare the early failure rates of guided and non-guided implant surgery, as well as implant placement site and implant system used.
Methods: A one-year retrospective evaluation of electronic health records (EHRs) was conducted at the University of Pittsburgh, School of Dental Medicine (SDM). Implants placed from February 28th, 2022 to March 1st, 2023 were recorded. Whether they were guided or unguided, all failure implants within the same time frame were evaluated. The placement site and implant systems used were documented.
Results: 456 implants were placed. Only 20 implants failed, representing a 4.2% failure rate. 220 implants were placed in the mandible. 236 implants were placed in the maxilla. There was no statistically significant difference in the early failure rate between the maxilla and the mandible (p>0.05). In terms of early implant failure, there was no statistical difference between the guided and non-guided surgical protocols (p>0.05). NobelActive (Nobel Biocare) demonstrated a failure rate of 16.42%, which was statistically significant (p<0.05) when compared to other implant systems.
Conclusion: Within the limitations of this study, there was no difference between guided and non-guided surgical protocols in terms of early implant failure. Maxillary or mandibular implant placement had no effect on early implant failure. The implant systems used had statistically significant failure rate differences, but the correlation was unclear. Therefore, future studies should investigate further systemic and local factors that may be associated with early implant failure to provide stronger evidence.
