Abstract：
BACKGROUND: Chin prosthesis implantation, a cosmetic procedure to correct chin asymmetry, depression, or retraction, is generally safe and simple. However, its long-term effects on surrounding tissues are a concern. This study aimed to use three-dimensional (3D) scanning to classify the mentalis muscle shapes and assess the impact of prosthesis implantation on these muscles.
METHODS: This study evaluated 450 eligible female participants. Using three-dimensional imaging, data on the types, thickness, width, and length of the left and right mentalis muscles were collected and summarized. The impact of chin prosthesis on these muscle dimensions was assessed using analysis of variance, and the effect on muscle type was determined using χ2 test.
RESULTS: Chin implant placement affected the mentalis muscles, resulting in increased length, thickness, and width. The subjects\' mentalis muscles were categorized into 3 types and divided into 7 subtypes. χ2 test results indicated that implantation influences the classification of these muscles.
CONCLUSIONS: Recognizing how implant placement affects the mentalis muscle can guide the development of treatments to mitigate these changes. Additionally, understanding the muscle\'s morphology enables more precise treatment approaches for patients.

摘要：
背景：Chin假体植入，矫正下巴不对称的整容手术，抑郁症,或撤回，通常是安全和简单的。然而,它对周围组织的长期影响令人担忧。本研究旨在使用三维（3D）扫描来对下颌肌肉的形状进行分类，并评估假体植入对这些肌肉的影响。
方法：本研究评估了450名符合条件的女性参与者。使用三维成像，类型上的数据，厚度,宽度,收集并总结了左、右下颌肌的长度。使用方差分析评估了下巴假体对这些肌肉尺寸的影响，对肌肉类型的影响采用χ2检验。
结果：Chin植入物的放置影响了mentalis肌肉，导致长度增加，厚度,和宽度。受试者的精神肌分为3种类型，分为7种亚型。χ2检验结果表明，植入会影响这些肌肉的分类。
结论：认识到植入物放置如何影响下颌肌可以指导治疗的发展，以减轻这些变化。此外,了解肌肉的形态可以为患者提供更精确的治疗方法。
