This study aims to systematically review and identify the changes of occlusion in patients after orthognathic surgery.
The protocol was developed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols (PRISMA-P) and was registered to the International Prospective Register of Systematic Reviews (PROSPERO) under the registration number CRD42021253129. Studies included were Original articles only, Additionally, studies were included if the outcome of occlusal force was measured pre- and postoperatively and if occlusal forces resulted from a long follow-up of a minimum of 1 year following orthognathic surgery using adequate measurement tools. Non-English articles, case reports, case series, and non-original articles, including systematic reviews and literature reviews, were excluded.
The search strategy yielded a total of 978 articles. Of the 978 articles, 285 were duplicates. After reading the titles and abstracts, 649 articles were excluded, and full-text articles of the remaining 47 studies were reviewed independently by two authors for eligibility wherein 33 articles were excluded, because they did not meet the inclusion criteria. Finally, a total of 14 studies were processed for critical review.
The occlusal force increased after orthognathic surgery, although not to the level of the control group; however, the maximal bite force remained unchanged. Immediately after orthognathic surgery, chewing and swallowing forces increased. Significant reductions in the postoperative occlusal contact pressure areas was also observed.
本研究旨在系统回顾和确定正颌手术后患者的咬合变化。
该方案是根据系统评价和荟萃分析首选报告项目（PRISMA-P）制定的，并在国际前瞻性系统评价注册（PROSPERO）下以注册号 CRD42021253129 进行了注册。仅纳入原始文章，此外，如果在正颌手术后至少 1 年的长期随访中使用了足够的测量工具来测量咬合力，并报告了术后的咬合力结果，则纳入研究。排除非英语文章、病例报告、病例系列以及非原始文章，包括系统评价和文献综述。
搜索策略共产生了 978 篇文章。在 978 篇文章中，有 285 篇是重复的。在阅读标题和摘要后，排除了 649 篇文章，然后由两名作者独立对其余 47 篇研究的全文进行了评估，其中 33 篇文章因不符合纳入标准而被排除。最后，对 14 项研究进行了严格审查。
尽管正颌手术后的咬合力没有达到对照组的水平，但咬合力确实增加了；然而，最大咬合力保持不变。正颌手术后，咀嚼和吞咽力量立即增加。术后咬合接触压力区也显著减少。
