| 摘要 | 本研究目的，乃探讨矫正治疗前后与「微笑指标」之关联性，并分析其对微笑的影响。研究材料从中华民国齿颚矫正学会专科医师考试合格病例中，选取九十份档案，含治疗前后正面微笑照片和侧方测颅X光片。将每一病患微笑照片数字影像化，并量取事先设计之七种微笑测量值，同时量侧方测颅X光片十四项分析值，以T-test、ANOVA和Pearson's correlation analysis分析治疗前后微笑变化与其相关因素之关联性。结果显示：部分微笑表现和拔牙与否、性别、异常咬合分类等无相关性；但和年龄、骨骼分类等因素有明显关联性(p<0.05)；矫正治疗后，U1-SN、L1-NB、U1-NA(°)之改变对部分微笑现有明显的改善。因此，矫正治疗对微笑变化具有部分影响，但有关微笑标准化之相关研究有待进一步研究。 The purposes of this research were to discuss changes in the smile after orthodontic treatment and to find the factors affecting smile changes during orthodontic treatment. Pre- and post-treatment frontal smile pictures and lateral cephalometric records were collected from 90 case files of the Specialists Examination of the Taiwan Association of Orthodontists. Pre-and post-treatment smile pictures were coordinated and measured with Adobe Photoshop 4.0 using a personal computer. Seven percentage measurements and fourteen cephalometric measurements were made from all collected pictures and cephalometric tracings, respectively. The post-treatment measurements were subtracted from pretreatment measurements to represent treatment changes in the smile and craniofaciadental morphology. t-test, ANOVA, and Pearson's correlation analysis were used to compare the correlation of the smile and craniofaciadental morphologies between pre- and post-treatment. The results showed that (1) there were no correlations among gender, malocclusion, extraction type, and smile changes; (2) there was a significant statistical difference (p<0.05) between the skeletal type (and age) and some smile changes; and (3) from the cephalometric measurements, U1-SN and U1-NA were significantly correlated with some smile changes (all p<0.05). In conclusion, orthodontic treatments can improve the smile; however, a scientific and objective method to evaluate smile changes still needs to be developed. |
