Introduction: The purpose of this study was to systematically reviewthe stability of maxillary incisors after class III malocclusion surgery. Objective: Our study aimed to evaluate the stability of maxillary incisors after class III malocclusion surgery through a systematic review. Materials and methods: An electronic search of databases retrieved 189 publications concerning our topic. Following the application of inclusion and exclusion criteria, four studies remained. Among other data, treatment methods, outcome measures during treatment, and time at follow-up were all extracted from the relevant articles. A subjective assessment of study quality was performed. The heterogeneity of the samples and treatment methods refrained us from performing a meta-analysis. Results: One hundred and sixty-seven patients with class III malocclusion underwent orthognathic surgery, seventy-eight of them benefited a bimaxillary surgery. Concerning the maxillary incisor stability, the studies suggest that performing the First Approach of the surgery is as stable as the conventional approach one. Conclusions: To evaluate the real stability of the maxillary incisor, further research with longer follow-up periods is required.
