Abstract

Objective: To evaluate the position and orientation of the mandibular proximal segment and the volume of condylar and coronoid processes in class II and III patients submitted to bimaxillary orthognathic surgery, using cone beam computed tomography scans.

Methods: Class II and III patients who underwent bimaxillary orthognathic surgery were evaluated by fusing their preoperative virtual planning and postoperative outcomes. The CBCT scans were import into Dolphin Imaging Software and the images were superimposed. The superimposition of the planned and postoperative CBCT images was performed with the voxel-based method. Results: Differences were found in condylar resorption between class II and III.

Conclusion: The displacement of the mandibular proximal segment after orthognathic surgery was negligible and supported by the condyle and coronoid process, which demonstrated with a clinically non-relevant resorption and postoperative stability.

正颌手术后下颌近段、髁突及冠突的三维评价。

目的：应用锥束计算机断层扫描评价II类和III类患者行双颌正颌手术后下颌近段的位置和方向以及髁突和冠突的体积。方法：对行双颌正颌手术的II类和III类患者进行术前虚拟计划和术后结果的融合评估。将CBCT扫描输入Dolphin Imaging Software，并将图像进行叠加。采用基于体素的方法对计划和术后CBCT图像进行叠加。结果：II型与III型在髁突吸收方面存在差异。结论：正颌手术后下颌近端移位可忽略不计，由髁突和冠突支撑，表现出临床不相关的吸收和术后稳定性。

期刊介绍： CRANIO: The Journal of Craniomandibular & Sleep Practice is the oldest and largest journal in the world devoted to temporomandibular disorders, and now also includes articles on all aspects of sleep medicine. The Journal is multidisciplinary in its scope, with editorial board members from all areas of medicine and dentistry, including general dentists, oral surgeons, orthopaedists, radiologists, chiropractors, professors and behavioural scientists, physical therapists, acupuncturists, osteopathic and ear, nose and throat physicians. CRANIO publishes commendable works from outstanding researchers and clinicians in their respective fields. The multidisciplinary format allows individuals practicing with a TMD emphasis to stay abreast of related disciplines, as each issue presents multiple topics from overlapping areas of interest. CRANIO''s current readership (thousands) is comprised primarily of dentists; however, many physicians, physical therapists, chiropractors, osteopathic physicians and other related specialists subscribe and contribute to the Journal.
