摘要
人类恒牙的萌出与上下颌骨的增长在一定时间内相互协调地进行,在口腔里就不发生牙颌畸形。由于某些不良因素的影响使它们之间的萌长关系失调,则造成牙颌畸形。在我国对牙颌畸形的正畸治疗均限定在16岁以下进行。牙颌畸形多出现在前牙区,影响美观和咀嚼功能,成年人要求治疗者日益增多。近十年来(1983～1993)笔者对215例成年人(16～38岁)前牙列牙颌畸形进行了矫治临床研究,采用疗法以用活动矫正器为主,个别情况采用固定矫正器。矫治后复查结果在改进患者的面容美观和增强咀嚼功能方面,均取得较好的疗效。通过215例各种不同前牙列牙颌畸形的病例分析,对患者的年龄、口腔检查、矫正器的选择及疗效标准等方面进行了探讨。
For human beings the eruption of permanent teeth begins from 6 to 13 years ot age (except the wisdom teeth ,but the growth and development of upper and lower jaws are stabilized at about the age of 16. They are acting harmoniously on each other at a certain time without the occurrence of malocclusion of the teeth. Owing to some unfavourable factors, the relation of the two above conditions is disturbed .malocclusion of the permanent anterior teetb often occurs, In our country the ideal time for orthodontic treatment mostly is limited to the age of under 16. In the last 10 years ( 1983-1993) , A study was earned out on 2 1 5 adult patients ( aged between 1 6-38 ) with malorrlusion of anterior teeth, they were mostly cured with removable orthodontic activators, in some individual cases fixed activators were used. On the reexamination of treated patients,their facial appearance were more improved and the masticatory function more increased than before- The different kinds of anterior teeth malocclusion and the selection of activators and their curative effects were discussed in detail.
