【摘要】：目的:对云南地区人群进行三维头影测量分析,为牙颌面畸形及颞下颌关节病患者的诊治提供参考依据。材料与方法:研究一:选取到昆明医科大学附属口腔医院就诊的云南地区患者共727例,其中男性365例,女性362例,年龄11～65岁,平均29. 5岁。以年龄分为3组。利用SimPlant 11.04软件进行三维头影测量分析,以颅颌面硬组织相关24个标志点进行定点,并对测量结果进行比较分析。研究二:选昆明医科大学附属口腔医院口腔颌面外科诊治的4例牙颌面畸形、10例颞下颌关节强直及6例单纯喙突增生(无颞下颌关节器质性病变)患者,进行三维头影测量分析。对4例牙颌面畸形患者行正颌外科手术,10例颞下颌关节强直患者行颞下颌关节成型术加喙突切除术,6例喙突增生患者行喙突切除术,并对术后的开口度进行统计分析。结果:1.骨组织角度及牙槽角度、线距及面宽、下颌骨宽及颧骨宽在CBCT-3D与CBCT-2D中比较具有显著性差异(P0.05)。面宽、下颌骨宽及颧骨宽在CBCT-3D中性别具有显著性差异(P0.05)。成年中男性与女性的面下部高度(ANS-Me)具有显著性差异(P0.05)。2.4例牙颌面畸形患者顺利完成正颌外科手术,术后患者达到较好的美学效果与良好的咬合关系,治疗效果满意。10例颞下颌关节强直及6例喙突增生患者手术后张口度均得到明显改善。结论:1.CBCT-3D与CBCT-2D测量结果存在一定的差异,CBCT-3D数据相对较为可靠。并且,成年男性面下部高度大于女性。正常人群中男性的颧骨、下颌骨、面宽较女性明显。基于CBCT三维头影测量值可以为临床提供参考依据。2.牙颌面畸形患者经过正颌外科手术治疗,外貌及口颌功能均得到明显改善,治疗效果确切,颅颌面硬组织数据具有较好的参考价值,具有有效的可靠性。此外,建立喙突长度标准值可为喙突增生的患者提供参考及临床应用价值。
[Abstract]:Objective: to provide a reference for the diagnosis and treatment of odontomaxillofacial malformation and temporomandibular arthropathy. Materials and methods: 1. A total of 727 patients in Yunnan Province were selected from the affiliated Stomatological Hospital of Kunming Medical University, 365 males and 362 females, aged 1165 years, with an average of 29.9 years. Five years old. They were divided into 3 groups according to their age. Three-dimensional cephalometric analysis was carried out with SimPlant 11.04 software, and 24 markers of craniomaxillofacial hard tissue were used for fixed points, and the results were compared and analyzed. Study 2: four patients with maxillofacial malformation, 10 patients with temporomandibular joint ankylosis and 6 patients with simple coracoid process hyperplasia (without temporomandibular joint organic lesion) were selected from oral and maxillofacial surgery, affiliated to Kunming Medical University. 3 D cephalometric analysis. Four patients with maxillofacial malformation were treated with orthognathic surgery and 10 patients with temporomandibular joint ankylosis underwent temporomandibular arthroplasty plus coracoid process resection. Coracoid process resection was performed in 6 patients with coracoid process hyperplasia. The result is 1: 1. There were significant differences in bone tissue angle, alveolar angle, line distance and facial width, mandibular width and zygomatic width between CBCT-3D and CBCT-2D. There were significant differences in facial width, mandibular width and zygomatic width in CBCT-3D. There was significant difference between male and female in lower facial height (ANS-Me). The orthognathic surgery was successfully completed in 2.4 patients with dental and maxillofacial malformation. The results were satisfactory. 10 cases of temporomandibular joint ankylosis and 6 cases of coracoid process hyperplasia were obviously improved after operation. Conclusion 1. There is a certain difference between CBCT-3D and CBCT-2D measurement results. CBCT-3D data are relatively reliable. Moreover, the lower face height of adult males was higher than that of females. The zygomatic bone, mandible and facial width of the male were significantly larger than that of the female in the normal population. The three-dimensional cephalometric value based on CBCT can provide reference basis for clinical. 2. 2. After orthognathic surgery, the appearance and oral and maxillary function of the patients with maxillofacial malformation were obviously improved. The data of craniomaxillofacial hard tissue had good reference value and effective reliability. In addition, establishing the standard value of coracoid process length can provide reference and clinical application value for patients with coracoid process hyperplasia.
