One of the main problems of orthognathodontic surgery is to evaluate the effects on soft tissue of bone positioning performed following surgical programming. A method which is of particular interest, easy to perform and reproduce was proposed by Jensen in 1992. It evaluates the correspondence of soft tissues on the basis of surgical programming and allows percentage values of soft tissue movement to be calculated in relation to bone tissue, thus performing a surgical VTO which corresponds as closely as possible to the postoperative result. It is important to remember that surgical programming is essentially based on the aesthetic and clinical analysis of the patient, the evaluation of the records collected, the surgeon's sensitivity dictated by his experience and his aesthetic sense which may result in an increasingly reliable VTO.
正颌外科手术的主要问题之一是评估按照手术规划进行的骨定位对软组织的影响。1992年詹森提出了一种特别有趣、易于实施和重复的方法。它根据手术规划评估软组织的对应关系，并允许计算相对于骨组织的软组织移动百分比值，从而进行尽可能接近术后结果的手术虚拟排牙试验（VTO）。必须记住，手术规划本质上基于对患者的美学和临床分析、对所收集记录的评估、由外科医生经验决定的敏感度以及其审美意识，这可能会产生越来越可靠的VTO。
