Abstract

Objectif: This study aims to assess the impact of presurgical mandibular incisor inclination on the stability of surgical class III patients.

Methods: An electronic search was conducted on PubMed, Scopus, Web of Science, EBSCO, and the Cochrane Library from 2014 to February 2025, initially identifying 351 publications relevant to our review.

Results: Four retrospective studies were included in this review, with the risk of bias ranging from low to serious. A preoperative retroinclined incisal axis leads to an increased post-surgical overjet and inadequate interincisal contact, indicating that retroclined mandibular incisors may affect skeletal stability. However, Overcorrection of mandibular incisor inclination could increase the risk of skeletal relapse, a proinclined lower incisal axis may result in a postoperative negative overbite and contribute significantly to relapse.

Conclusions: The studies indicate that achieving an optimal postsurgical overjet through adequate presurgical mandibular incisor decompensation may significantly contribute to the postsurgical stability of Class III surgical orthodontic treatment. In contrast, excessive correction of mandibular incisors did not contribute to mandibular stability.
