摘要/Abstract

摘要： 目的:研究广州地区青少年正常牙合人群临床冠中心点连线的分布规律,对直丝弓托槽的垂直向定位进行探讨。方法:制取59例广州市正常牙合青少年人群的牙颌模型,使用数显游标卡尺测量临床牙冠高度并确定临床牙冠中心点,对临床牙冠中心点的水平向及垂直性数据通过简易模型二维测量仪进行二维测量,它的结果用计算机软件描绘出来,形成临床牙冠中心点连线,并对连线形态进行分析。结果:广州市青少年正常牙合人群的临床牙冠中心点连线是可以归纳成几个有规律的折线。结论:正常牙合青少年人群的临床牙冠中心点连线并非都在一条直线上,临床上不应该完全按照临床牙冠中心点的高度进行托槽的粘接定位。

Abstract: Objective: To evaluate the patterns of midpoints lines of facial axis (FA) point and discuss its relationship with pre-adjusted bracket positioning. Methods: Fifty-nine sets of stone models were prepared from teenagers of normal occlusion. The height of clinical crown was measured with a vernier and the midpoints of the FA point were determined. The horizontal and vertical data of the center point of clinical crown were measured by a simple two-dimensional model measuring instrument. The lines of the midpoints of FA which were drawn with computer software were analyzed. Results: The central points of the clinical crowns of adolescents with normal occlusion in Guangzhou could be summarized into several regular zigzag lines. Conclusion: The FA points between the teeth were not always on the same plane. It was recommended that the ideal position to place the bracket was not the center of the labial surface of the tooth

Key words: clinical height of crown center, bracket placement, normal occlusion
