Abstract

The purpose of this systematic review was to define the effectiveness of palatally positioned dental implants placed in atrophic maxillae. Searches were performed in five databases including the gray literature, up to August 2021, by 2 independent reviewers, in order to answer the following research question: Is the palatal approach technique effective in the rehabilitation of atrophic maxillae? In the initial search, 1948 articles were found and after applying the inclusion and exclusion criteria, five studies were selected, none of which was a randomized clinical trial. A total of 681 implants were placed, 549 of them with a palatal approach and 132 at the alveolar crest, with an effectiveness of 98.38% and 99.5%, respectively, with no statistically significant difference between the groups. In assessing the risk of bias, only one of the studies had a low risk of bias. Implants installed with the palatal approach technique showed high effectiveness for rehabilitation of atrophic maxilla; however, few studies in the literature report this technique, requiring more controlled studies, and with less risk of bias, to confirm the results obtained in this systematic review.
