Abstract
BackgroundChin 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 aims to use three-dimensional (3D) scanning to classify mentalis muscle shapes and assess the impact of prosthesis implantation on these muscles. MethodThis 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 (ANOVA), and the effect on muscle type was determined using the chi-square test. ResultsThe findings show that chin implant placement affects the mentalis muscles, resulting in increased length, thickness, and width. Analysis categorized the subjects' mentalis muscles into three types, further divided into seven subtypes. Chi-square test results indicate that implantation influences the classification of these muscles. ConclusionRecognizing 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.
