不同影像学技术对正畸治疗中牙根吸收评估的特点分析

Analysis of characteristics of root absorption assessment in orthodontic treatment with different medical imaging technology

正畸治疗中对牙根吸收的评估在正畸学的研究中起着很重要的作用。随着现代医疗检测设备的发展,准确性较高的牙根吸收度的测量技术相继问世和推广,牙根吸收的研究取得了较大的进展。本文就现有临床采用的根尖周片、曲面体层片、头颅侧位片、多层螺旋CT、锥形束CT等主要影像学技术检测牙根吸收的特点作一综述。

The assessment of root absorption in orthodontic treatment plays a very important role in the study of orthodontics. With the development of modern medical testing equipments,the high- accuracy measuring technology of evaluating root absorption has been available and generalized. More progress has been made in the research on root absorption. This paper tries to discuss the characteristics of root absorption detection applied clinically with the main imaging technology which includes periapical radiograph,panoramic radiograph,lateral cephalogram,multi- slice spiral computed tomography,cone beam computed tomography（ CBCT） and so on.
