Abstract

Introduction: The aim of this in vitro study was to determine if there is a significant difference in the excess adhesive flash between the metallic APC™ Flash-Free adhesive system, the APC™ pre-coated adhesive system and a conventional uncoated system.

Materials and methods: One hundred eighty-six freshly extracted human premolars were randomly and blindly divided into three groups according to the type of brackets. Group A (control group n=60): The conventional uncoated metallic bracket (Victory, 3M Unitek®) with a Transbond XT™ Light Cure Adhesive Paste was used. Group B (n=60): The APC™ II metallic maxillary precoated premolar brackets was used. Group C (n=66) : The metallic APC™ Flash-Free adhesive system without flash clean up was used. Images were taken at 40 magnifications in a dental microscope (Leica M320 for dental, Wetzlar, Germany) then analyzed with the ImageJ software and the area of excess adhesive flash was measured.

Results: The mean percentage was significantly different between the three groups (p<0.001; ANOVA). It was significantly smaller for brackets in the APC Flash-Free group (p<0.001), and the difference was not significant between conventional brackets and APC (p=0.224).

Discussion: The new technique seems to reduce the amount of excessive adhesive around orthodontic brackets.

金属APC™免闪胶系统周围多余胶的对比研究

本体外研究的目的是确定金属APC™无闪胶系统、APC™预涂胶系统和传统未涂胶系统之间是否存在显著差异。材料与方法:将186颗新鲜拔除的人前磨牙按托槽类型随机盲目分为3组。A组(对照组n=60):使用传统的无涂层金属支架(Victory, 3M Unitek®)和Transbond XT™光固化胶膏。B组(n=60):使用APC™II金属上颌预涂前磨牙托槽。C组(n=66):采用金属APC™flash - free胶粘剂体系，不进行闪光清理。在牙科显微镜(Leica M320牙科显微镜，Wetzlar, Germany)上以40倍放大镜拍摄图像，然后用ImageJ软件进行分析，并测量多余的粘附闪光面积。结果:三组间的平均百分比有显著性差异(p)讨论:新技术似乎减少了正畸托槽周围过量粘接剂的数量。
