CAD/CAM splint based on soft tissue 3D simulation for treatment of facial asymmetry
نویسندگان
چکیده
BACKGROUND Most cases of facial asymmetry involve yaw deformity, and determination of the yaw correction level is very difficult. METHODS We use three-dimensional soft tissue simulation to determine the yaw correction level. This three-dimensional simulation is based on the addition of cephalometric prediction to gradual yaw correction. Optimal yaw correction is determined visually, and an intermediate splint is fabricated with computer-aided design and computer-aided manufacturing. Application of positioning devices and the performance of horseshoe osteotomy are advisable. RESULTS With this procedure, accurate repositioning of jaws was confirmed and patients obtained fairly good facial contour. CONCLUSIONS This procedure is a promising method for a widespread, predictable treatment of facial asymmetry.

A retrospective study was conducted to explore the application of digital model surgery in the treatment of dento-maxillofacial deformities. Fifteen patients with dento-maxillofacial deformities were enrolled in this study. A digital craniomaxillofacial-dentition model was established by combining three-dimensional (3D) computed tomography (CT) and laser-scanned dentition models. Based on this ...

متن کاملThree-dimensional surgical simulation for facial asymmetry: soft tissue-, skeleton-, and occlusion-based planning
Using three-dimensional (3D) computerized simulation systems has enabled us to determine the anticipated position of the maxilla and mandibular proximal and distal segments. The bony segments need to be mobilized according to the planned final position. The concept of 3D surgical planning in orthognathic surgery has evolved continuously. While using 3D simulation for planning the correction of ...
