Video imaging has become a popular tool for predicting soft tissue profiles. However, it is important not to create false expectations with its use. The purpose of this study was to evaluate the clinical acceptability of video imaging for the prediction of soft tissue changes in mandibular advancement orthognathic surgery, and thus, to determine its suitability for patient presentation, education, and subsequent treatment planning. Simulated mandibular advancements were performed on 30 patients (21 women and 9 men) using the Dentofacial Planner Plus v1.5 software program. Two separate panels consisting of 25 laypersons and 25 dental professionals (17 orthodontists and 8 oral and maxillofacial surgeons) compared prediction images to actual posttreatment images. Overall profile predictions were found to be clinically acceptable by orthodontists and oral and maxillofacial surgeons in 87.8% of the cases and by laypersons in 95.6% of the cases. No significant differences were found among the individual facial regions graded by the dental professional panel. The results of this study suggest that video imaging is an acceptable tool for profile prediction.
视频成像已成为预测软组织轮廓的常用工具。然而，使用时不要产生不切实际的期望，这一点很重要。本研究的目的是评估视频成像在预测下颌前徙正颌手术中软组织变化方面的临床可接受性，从而确定其在患者展示、教育及后续治疗计划中的适用性。使用Dentofacial Planner Plus v1.5软件程序对30例患者（21名女性和9名男性）进行模拟下颌前徙。由25名外行人及25名牙科专业人员（17名正畸医生和8名口腔颌面外科医生）组成的两个独立小组将预测图像与实际治疗后图像进行比较。正畸医生和口腔颌面外科医生发现，87.8%的病例中整体轮廓预测在临床上是可接受的，外行人在95.6%的病例中认为可接受。牙科专业人员小组对各个面部区域的评分没有显著差异。本研究结果表明，视频成像是一种可接受的轮廓预测工具。
