Background: This study aimed to assess the survival of implants placed in the maxillary tuberosity or in the pterygomaxillary region of the maxilla, based on a systematic review of the literature. Methods: An electronic search was undertaken in three databases. The cumulative survival rate (CSR) was calculated. The log-rank (Mantel–Cox) test was used to compare the survival distributions between some groups. Results: Thirty-eight studies were included, reporting 3446 implants (3053 pterygoid, 393 tuberosity) in 2245 patients, followed up for a mean ± SD of 61.0 ± 36.3 months (min–max, 1–144). A total of 208 pterygoid and 12 tuber implants failed, with a clear concentration of failures in the first year of follow-up and a 10-year CSR of 92.5% and 96.9%, respectively. The survival of pterygoid implants was lower than that of implants in the maxillary tuberosity (p = 0.006; log-rank test), and the survival of implants submitted to early/delayed loading was lower than that of immediately loaded implants (p < 0.001; log-rank test). Non-splinted implants presented higher failure rates. Few cases of intra- or postoperative complications were reported. Conclusions: Implants placed in the pterygoid process/maxillary tuberosity present a high 10-year CSR, although with lower survival for pterygoid in comparison to tuber implants. Pterygoid/tuber implants that are splinted with other implants may present higher survival rates than those that are not splinted.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
