A The Simulated Osteotomies Were Completed The Maxilla Segment Was A, the simulated osteotomies were completed; the maxilla segment was cut and separated. b, the maxillary segment was moved to the desired position according to the preoperative design. For pre treatment assessment and surgery planning, 3d images were performed and the data were used to plan the osteotomies and the maxilla relocation with the “mimics” software version 21.0.

A The Simulated Osteotomies Were Completed The Maxilla Segment Was A, the simulated osteotomies were completed; the maxilla segment was cut and separated. b, the maxillary segment was moved to the desired position according to the preoperative design. The osteotomies were completed based on the osteotomy lines on the templates, and the maxillary segment was separated. the prebent plates were then installed correspondingly by placing screws in the appropriate screw holes. as the screws were tightened, the displaced segment was automatically repositioned to the planned location . bsso was. Step 2: virtual triangles were constructed on the maxilla and distal mandibular segment by using previously validated cephalometric landmarks (table 1) 8, 20. table 1 definitions of the 3d. A three dimensional (3d) finite element model of a hemimaxilla was constructed. through a conventional le fort i osteotomy, 2 and 3 mm of posterior movement in a parallel and rotational manner were simulated and the displacement pattern of the maxilla in each movement type was evaluated.

Transverse maxillary hypoplasia with vertical excess. methodically, the maxilla is divided into three segments with a remaining central nasal portion, sparing the central nasopalatal plate. the palatal, parasagittal osteotomies can be performed piezosurgically. the second segment is the tooth bearing alveolar rim. Assisted piezoelectric osteotomies, and computerized morphometric analysis. results: simulated maxillo malar osteotomies were successfully replicated in the operating room, as shown by accuracy evaluation performed using three dimensional analysis. in long term follow up period, no permanent complications were assessed. superimposition between.
