[Evaluation of tegumental changes after skeletal repositioning in orthodontic surgery].

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.
