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.
本系统评价的目的是确定放置于萎缩性上颌骨的腭侧牙种植体的有效性。截至2021年8月，两名独立评价者在包括灰色文献在内的五个数据库中进行检索，以回答以下研究问题：腭侧入路技术在萎缩性上颌骨修复中是否有效？在初步检索中，共找到1948篇文章，应用纳入和排除标准后，选择了五项研究，其中没有一项是随机临床试验。总共植入了681颗种植体，其中549颗采用腭侧入路，132颗位于牙槽嵴顶，有效率分别为98.38%和99.5%，两组之间无统计学显著差异。在评估偏倚风险时，只有一项研究的偏倚风险较低。采用腭侧入路技术植入的种植体在萎缩性上颌骨修复中显示出较高的有效性；然而，文献中报道该技术的研究较少，需要更多对照研究且偏倚风险更低的研究来证实本系统评价中获得的结果。
