Achieving a normal soft tissue facial profile is considered to be the main concern of class III patients and the goal of most class III treatments.
The purpose of this study was to investigate the effects of facemask treatment on profile with photogrammetric method.
Before (T0) and after (T1) treatment photograms of 40 class III patients profiles (20 male and 20 female individuals) treated with protraction face mask that met the inclusion criteria were digitized and analyzed using Aesthetic Analyzer software. Selected linear and angular measurements were performed for each patient and the changes were noted.
An increase in inferior facial height (< 0.001) and inferior facial angle (< 0.001) was observed. Nasal prominence and upper lip prominence also increased significantly (< 0.001). Advancement of sub nasal area was observed to be significant in females (< 0.05) in contrast to males.
Remarkable advancement in the middle face and consequent fullness in the soft-tissue profile can be achieved by using protraction face mask. The response to treatment is not different between males and females.
实现正常的面部软组织轮廓被认为是III类患者的主要关注点以及大多数III类治疗的目标。
本研究的目的是采用摄影测量法研究面罩治疗对面部轮廓的影响。
对40例符合纳入标准的接受前牵引面罩治疗的III类患者(20名男性和20名女性)治疗前(T0)和治疗后(T1)的面部轮廓照片进行数字化处理,并使用美学分析仪软件进行分析。对每位患者进行选定的线性和角度测量,并记录变化情况。
观察到面下高度(<0.001)和面下角度(<0.001)增加。鼻突度和上唇突度也显著增加(<0.001)。与男性相比,女性鼻下区域的前移显著(<0.05)。
使用前牵引面罩可实现中面部的显著前移以及软组织轮廓的饱满。男性和女性对治疗的反应没有差异。
