上前牙美学比例喜好度的调查

Assessment of esthetic ratio in maxillary anterior teeth

目的:研究不同人群对上前牙不同美学比例的态度。方法:采用网络问卷调查的方式研究人们对上中切牙不同宽/长比、相邻上前牙之间不同宽度比的态度。结果:共收到调查结果 1350份,对于理想的上中切牙的宽/长比,受调查者选择最多的是86%的比例,其次是70%、78%,选择这三种比例的人数占到全部受调查者的88.1%。对于相邻上前牙之间的宽度比,Preston比例的选择率最多,其次为70%及80%的重复比例,选择这三种比例的人数占到总受调查者的80.9%。结论:上中切牙的理想宽/长比不是一个具体数值而是一个范围,在70%-86%左右。在相邻上前牙之间的宽度比方面,Preston比例是最受欢迎的,而70%至78%左右的重复比例也是被认可的。而口腔科工作人员与普通人对这两项牙齿美学参数的选择有差异。

Objective： To evaluate the attitudes of different people towards various esthetic ratio of maxillary anterior teeth. Methods： A web-based survey was performed to study people＇s preferences of two dental esthetic concepts as followed： The width/length ratio of upper central incisor, the width/width ratio of maxillary anterior teeth. Results： A total of1350 subjects responded to the survey were analyzed. For different width/length ratios of upper central incisor, the favorite ratio was 86%, followed by 70% and 78%. 88.1% of the total selected one of the three ratios. For various width/width ratios of maxillary anterior teeth, more subjects chose Preston＇s proportion, followed by the ratios of 70% and 80%. 80.9% of the subjects selected one of these three ratios. Conclusion： The ideal width/length ratio of upper central incisor is within the range of 70% to 86% rather than a numerical value. The most favored width/width ratio of maxillary anterior teeth is Preston＇s proportion. A RED（recurring esthetic dental） proportion in a range of 70% to 78% is approbatory. There was significant difference on dental esthetics between dental professional and layman.
