Immediate postoperative outcome of orthognathic surgical planning, and prediction of positional changes in hard and soft tissue, independently of the extent and direction of the surgical corrections required.

Our purpose was to evaluate the immediate postoperative outcome of preoperatively planned and predicted positional changes in hard and soft tissue in 100 prospectively and consecutively planned and treated patients; all had various dentofacial deformities that required single or double jaw orthognathic correction using the computerised, cephalometric, orthognathic, surgical planning system (TIOPS). Preoperative cephalograms were analysed and treatment plans and prediction tracings produced by computerised interactive simulation. The planned changes were transferred to models and finally to operation.

Accuracy of combined maxillary and mandibular repositioning and of soft tissue prediction in relation to maxillary antero-superior repositioning combined with mandibular set back A computerized cephalometric evaluation of the immediate postsurgical outcome using the TIOPS planning system.

Aim: The purpose of the present study was to evaluate the immediate postsurgical outcome of planned and predicted hard and soft tissue positional changes in relation to maxillary antero-superior repositioning combined with mandibular set back using the computerized, cephalometric, orthognathic surgical planning system (TIOPS).

Material And Methods: Out of 100 prospectively and consecutively treated patients, 52 patients manifested dentofacial deformities requiring bimaxillary orthognathic surgery with maxillary antero-superior repositioning combined with mandibular set back and so were included. All patients were managed with rigid internal fixation (RIF) and without intermaxillary fixation (IMF).
