Abstract

Purpose: This study aimed to evaluate the efficacy of facial parameters (facial widths and proportions) in predicting the maxillary anterior teeth characteristics (teeth widths and ratios) through three-dimensional (3D) analysis.

Materials and methods: This cross-sectional study was conducted at the Stomatology Hospital of Fujian Medical University. Facial parameters of participants were obtained using a 3D facial scanner and subsequently imported into specific software for automated measurement. Intraoral data was captured by TRIOS 3. Pearson correlation analysis was employed to identify relationships between facial and intraoral measurements. Linear regression was performed on significantly correlated variables, while t-tests evaluated the accuracy of esthetic proportions (golden proportion [GP], golden mean [GM], and recurring esthetic dental [RED]) in predicting combined central incisor width (CIW) and combined anterior teeth width (CAW) (α = 0.05).

Results: A total of 147 volunteers participated in this study. Significant correlations for CIW and CAW were observed with facial widths (interpupillary width [IPW], intercanthal width [ICW], and intercommissural width [ICoW]) (p < 0.05). Regression equations based on these facial parameters revealed no significant differences between predicted and actual values for CIW and CAW. RED with ICW reliably predicted CIW without significant deviation from actual measurements (p > 0.05).

Conclusions: Anterior teeth widths can be reliably predicted using regression formulas derived from facial widths. The RED proportion provides a reliable method for predicting CIW.

基于面部和口腔内扫描的中国人面部宽度和上颌牙齿尺寸的相关性。

目的：本研究旨在通过三维（3D）分析，评价面部参数（面部宽度和比例）对上颌前牙特征（牙齿宽度和比例）的预测效果。材料与方法：本横断面研究在福建医科大学口腔医院进行。使用3D面部扫描仪获得参与者的面部参数，然后导入特定的软件进行自动测量。用TRIOS 3采集口内数据。使用Pearson相关分析来确定面部和口腔内测量之间的关系。对显著相关变量进行线性回归，t检验评估美学比例（黄金比例[GP]、黄金均值[GM]和复发性美学牙[RED]）预测中切牙联合宽度（CIW）和前牙联合宽度（CAW）的准确性（α = 0.05）。结果：共有147名志愿者参与了本研究。CIW和CAW与面部宽度（瞳孔间宽度[IPW]、腰间宽度[ICW]、腰间宽度[ICoW]）有显著相关性（p 0.05）。结论：利用面部宽度的回归公式可以可靠地预测前牙宽度。RED比例为预测CIW提供了可靠的方法。

期刊介绍： The Journal of Prosthodontics promotes the advanced study and practice of prosthodontics, implant, esthetic, and reconstructive dentistry. It is the official journal of the American College of Prosthodontists, the American Dental Association-recognized voice of the Specialty of Prosthodontics. The journal publishes evidence-based original scientific articles presenting information that is relevant and useful to prosthodontists. Additionally, it publishes reports of innovative techniques, new instructional methodologies, and instructive clinical reports with an interdisciplinary flair. The journal is particularly focused on promoting the study and use of cutting-edge technology and positioning prosthodontists as the early-adopters of new technology in the dental community.
