Abstract

Background: The anatomic characteristics of the masticatory muscles differ across craniofacial skeletal patterns.

Objective: To identify differences in the anatomic characteristics of masticatory muscles across different sagittal and vertical craniofacial skeletal patterns.

Eligibility criteria: Studies measuring the thickness, width, cross-sectional area (CSA), volume and orientation of masticatory muscles in healthy patients of different sagittal (Class I, Class II, and Class III) and/or vertical (normodivergent, hypodivergent, and hyperdivergent) patterns.

Information sources: Unrestricted literature searches in 8 electronic databases/registers until December 2023.

Risk of bias and synthesis of results: Study selection, data extraction, and risk of bias assessment with a customised tool were performed independently in duplicate. Random-effects meta-analysis and assessment of the certainty of clinical recommendations with the GRADE approach were conducted.

Results: 34 studies (37 publications) were selected with a total of 2047 participants and data from 16 studies were pulled in the meta-analysis. Masseter muscle thickness in relaxation was significantly greater by 1.14 mm (95% CI 0.74-1.53 mm) in hypodivergent compared to normodivergent patients while it was significantly decreased in hyperdivergent patients by - 1.14 mm (95% CI - 1.56 to - 0.73 mm) and - 2.28 mm (95% CI - 2.71 to - 1.85 mm) compared to normodivergent and hypodivergent patients respectively. Similar significant differences were seen between these groups in masseter muscle thickness during contraction as well as masseter muscle CSA and volume. Meta-analyses could not be performed for sagittal categorizations due to insufficient number of studies.

Conclusions: Considerable differences in masseter muscle thickness, CSA and volume were found across vertical skeletal configurations being significantly reduced in hyperdivergent patients; however, results should be interpreted with caution due to the high risk of bias of the included studies. These variations in the anatomic characteristics of masticatory muscles among different craniofacial patterns could be part of the orthodontic diagnosis and treatment planning process.

颅面骨骼形态与咀嚼肌解剖特征之间的关系:系统回顾与荟萃分析。
背景:不同颅面骨骼形态的咀嚼肌具有不同的解剖特征:不同颅面骨骼模式下咀嚼肌的解剖特征存在差异:确定不同矢状和垂直颅面骨骼模式下咀嚼肌解剖特征的差异:测量不同矢状(Ⅰ类、Ⅱ类和Ⅲ类)和/或垂直(正常发散、低度发散和过度发散)模式健康患者咀嚼肌的厚度、宽度、横截面积(CSA)、体积和方向的研究:截至 2023 年 12 月,在 8 个电子数据库/登记簿中进行了无限制的文献检索:研究选择、数据提取和偏倚风险评估均采用定制工具独立完成,一式两份。采用随机效应荟萃分析和 GRADE 方法评估临床建议的确定性:荟萃分析选取了 34 项研究(37 篇出版物),共有 2047 名参与者,其中 16 项研究的数据被纳入荟萃分析。与常发性和低发性患者相比,低发性患者放松时的颌下肌厚度明显增加了 1.14 毫米(95% CI 0.74-1.53 毫米),而高发性患者的颌下肌厚度则明显减少了- 1.14 毫米(95% CI - 1.56 至 - 0.73 毫米)和- 2.28 毫米(95% CI - 2.71 至 - 1.85 毫米)。这两组患者在收缩时的颌下肌厚度以及颌下肌CSA和体积方面也存在类似的明显差异。由于研究数量不足,无法对矢状面分类进行元分析:结论:在不同的垂直骨骼构型中,我们发现颌间肌的厚度、CSA和体积存在很大差异,而高分化患者的颌间肌厚度、CSA和体积明显减少;但是,由于纳入研究的偏倚风险较高,因此在解释结果时应谨慎。不同颅面形态的咀嚼肌解剖特征的这些变化可能是正畸诊断和治疗计划过程的一部分:ProCORMBERCO CRD42022371187 .

期刊介绍: Progress in Orthodontics is a fully open access, international journal owned by the Italian Society of Orthodontics and published under the brand SpringerOpen. The Society is currently covering all publication costs so there are no article processing charges for authors. It is a premier journal of international scope that fosters orthodontic research, including both basic research and development of innovative clinical techniques, with an emphasis on the following areas: • Mechanisms to improve orthodontics • Clinical studies and control animal studies • Orthodontics and genetics, genomics • Temporomandibular joint (TMJ) control clinical trials • Efficacy of orthodontic appliances and animal models • Systematic reviews and meta analyses • Mechanisms to speed orthodontic treatment Progress in Orthodontics will consider for publication only meritorious and original contributions. These may be: • Original articles reporting the findings of clinical trials, clinically relevant basic scientific investigations, or novel therapeutic or diagnostic systems • Review articles on current topics • Articles on novel techniques and clinical tools • Articles of contemporary interest
