Establishing common objectives and expectations concerning the outcome of proposed surgical orthodontic therapy is a crucial part of the treatment planning process, which has been greatly simplified by imaging software. The purpose of this study was to investigate the reliability of two surgical imaging programs--Dolphin Imaging 10 and Vistadent OC--in simulating the actual outcome of mandibular advancement surgery by using a visual analog scale (VAS) judged by a panel of orthodontists, oral surgeons, and laypersons. The predictions were also analyzed with soft tissue cephalometric evaluation. The results of the study showed that in predicting the surgical outcome evaluated by the VAS, both programs received a mean rating of fair. One was marginally superior for the overall assessment among all three panelist groups. Region-wise, rating indicated the lower lip region to be the least accurate, and the submental region received the highest scores. The soft tissue cephalometric parameters showed minimal differences except for the lower lip parameters. Thus, Dolphin Imaging 10 and Vistadent OC are reliable in predicting mandibular advancement surgical outcomes with inaccuracies chiefly in the lower lip region.
就正畸外科治疗预期结果确立共同目标和期望是治疗计划过程的关键部分，而影像软件已极大简化了这一过程。本研究的目的是通过使用由正畸医生、口腔外科医生和非专业人员组成的小组评判的视觉模拟量表（VAS），调查两种外科影像程序——Dolphin Imaging 10和Vistadent OC——在模拟下颌前徙手术实际结果方面的可靠性。预测结果还通过软组织头影测量评估进行了分析。研究结果表明，在预测由VAS评估的手术结果时，两个程序的平均评分均为中等。在所有三个评判小组中，其中一个程序在总体评估方面略占优势。按区域划分，评分表明下唇区域最不准确，颏下区域得分最高。除下唇参数外，软组织头影测量参数显示出极小差异。因此，Dolphin Imaging 10和Vistadent OC在预测下颌前徙手术结果方面是可靠的，主要在下唇区域存在不准确之处。
