Abstract

Objective: To evaluate the prevalence of temporomandibular disorders (TMDs) for those patients with dentofacial deformities, who underwent orthognathic surgery, and the control group. It also identified whether orthognathic surgery had a positive or negative impact on TMD symptoms by comparing TMD patients, who underwent orthognathic surgery, and people did not experience this surgery. Finally, this systematic review and meta-analysis aimed to evaluate the effectiveness of orthognathic surgery on the pre-existing TMDs in malocclusion patients. Material and Methods: MEDLINE, PubMed, Cochrane Library, Embase, ISI, google scholar have been utilized as the electronic databases for systematically reviewing the literature between 2001 and February 2019. Inclusion criteria were undergoing orthognathic surgery, patients with/without pre-existing TMDs, and physical disabilities. Results: A total of 669 abstracts and titles with potential relevance have been identified in the course of the manual and electronic searches. It has been found that five studies met our inclusion criteria for a systematic review. Temporomandibular disorders (TMDs) before orthognathic surgery in comparison to the controls (RR=0.02; 95% CI-0.08-0.13) and heterogeneity among the papers has been I2 = 42.86% (p=0.64). Conclusion: Malocclusion by orthognathic and orthodontics surgeries had a considerable rate of TMD compared to the controls. © 2020, Association of Support to Oral Health Research (APESB).
