骨性安氏Ⅲ类错(牙合)双颌手术后软组织的三维头影测量分析
3-Dimensinal evaluation of soft tissue cephalometric analysis after bimaxillary surgery in skeletal Angle Ⅲ
摘要
Abstract
Objective To evaluate the 3-dimensional cephalometric changes in the soft tissue of the skeletal class III malocclusion adult patients with facial asymmetry by orthodontic-surgical treatment. Methods The samples consisted of 10 audit Skeletal class III patients treated with orthodontic-surgical treatment using Bilateral Sagittal Split Ramus Osteotomy+Maxillary Osteotomy Lefort I +Genioplasty.3D computerized tomography images were taken 1 month before (To) and 6 months after (T1) bimaxillary surgery.Reconstruct three -dimensional mode is in CT post -processing workstation. The landmarks and variables of soft tissue were determined and measured to 3D cephalometric analysis. Results Concavity and facial asymmetry of all the patients were significantly corrected.The relationship of dental articulation were stable and perfect.The measurements of soft tissue variables after surgery: The width of nasal base, alae nasi and upper cupid bow point were significant increase.The width of cheilion and mandible were obviously decreased.The angle of LL-B'-Pog' and Go'-N'-Go' were evidently diminished.The rate of upper lip and chin dissymmetry were strikingly changed. Conclusion ①Satisfactory physiognomy of soft tissue can be obtained with bimaxillary surgery in severe skeletal class III malocc lusions with facial asymmethy; ②The 3-dimensional CT can precisely reflect characteristic of soft tissue in Maxillofacial region.In clinically,3D cephalometric analysis has a more use value.关键词
