摘要：

背景：咀嚼肌形态与颅面形态的密切相关性已经被报道，但是关于咀嚼肌形态与牙弓形态之间的相互作用关系还不明确。
目的：探讨咀嚼肌形态功能对牙弓形态的影响和作用机制。
方法：应用超声成像技术测量69位正常牙合青年男性下颌处于姿势位时浅层嚼肌横截面周长、面积、宽度、最大厚度、平均厚度、纵截面长度及颞肌前束最大厚度、平均厚度，并与牙弓测量指标进行统计学相关分析。
结果与结论：浅层嚼肌横截面的面积与上颌牙弓前中段长度，纵截面长度与下颌前段牙弓长度，最大厚度与下颌牙弓中段宽度及上颌牙弓周长呈正相关(P < 0.05)；颞肌前束最大厚度、平均厚度与上颌牙弓前段及前中段长度呈负相关(P < 0.05)，提示浅层嚼肌、颞肌形态功能可能是影响牙弓形态的因素之一。

Abstract:

BACKGROUND: Various studies have shown the association between masticatory muscle morphology and craniofacial morphology. However, the interaction between masticatory muscle morphology and dental arch form remains poorly understood.
OBJECTIVE: To investigate the influence of masticatory muscle morphology and function on dental arch forms and the underlying mechanisms.
METHODS: A total of 69 males with normal occlusion, aged 23.6 years (mean 18-28 years) were included in this study. Ultrasound scanning was used to measure the perimeter, area, width, length, mean thickness and maximal thickness of masseter muscle and the mean thickness and maximal thickness of anterior temporal muscle. All items were measured under mandibular postural position. The arch forms were measured. Correlation analysis was done between the ultrasound data and dental arch form.
RESULTS AND CONCLUSION: There was a positive correlation between the cross-section area of masseter muscle and the length of maxillary antero-middle dental arch, between the maximal thickness of masseter muscle and the width of mandibular middle dental arch and the perimeter of maxillary dental arch (P < 0.05). There was a negative correlation between the thickness of anterior temporal muscle and the length of maxillary anterior and antero-middle dental arch (P < 0.05). The results indicate that the function and morphology of masseter and temporal muscle may be one of the factors influencing the morphology of dental arch.
