Electronic searches were performed in PubMed\/MEDLINE, Scopus, Web of Science, and the Cochrane Library from inception to March 2026. Clinical studies evaluating maxillary RRR in patients rehabilitated with mandibular implant\u2010supported overdentures (IODs) were included. Because of heterogeneity in study designs, prosthetic protocols, and outcome assessment methods, the findings were synthesized qualitatively. The certainty of evidence was assessed using Grading of Recommendations, Assessment, Development and Evaluation (GRADE).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Eighteen studies involving 496 edentulous participants were included, comprising randomized controlled trials, prospective clinical studies, and retrospective investigations with 1\u201310 years of follow\u2010up. Mandibular treatments included 1\u2010IODs, 2\u2010IODs, 4\u2010IODs, and implant\u2010supported fixed dental prostheses. Maxillary RRR was generally comparable or reduced with mandibular IODs compared to conventional complete dentures. Resilient non\u2010splinting attachments, particularly O\u2010ring\/stud, ball, locator, and magnet systems, were generally associated with less maxillary RRR than rigid splinting designs such as bar\u2010clip and telescopic attachments. Implant number and distribution had limited influence, whereas anterior maxillary bone loss generally exceeded posterior loss. The certainty of evidence was low to moderate.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Mandibular IODs do not appear to substantially increase maxillary RRR compared with conventional dentures.
