摘要

目的:评价不拔除正畸矫治后上颌颊牙槽骨的修复效果。(锥梁研究)。材料与方法:采用EASY SMILE(美国)公司的自结扎托槽与常规托槽对20例青少年恒牙密集患者进行免拔牙治疗。治疗前(T0)和对准后(T1)分别进行锥形束计算机断层扫描。在上颌中切牙(I)、第二前磨牙(2PM)、第一磨牙中颊根(mb1M)和颊张根(db1M)处评估牙槽骨厚度(BT)。计算牙槽宽度变化与初始弓宽、初始拥挤、膨胀量、倾翻量、磨牙旋转量的相关性。所有收集到的数据将被制成表格并进行统计分析。结果:第一磨牙切牙和中颊根的BT明显减少,BH明显增加。此外,拱的尺寸通常随着倾倒而增加。骨质流失与前磨牙区域的拥挤和扩张量有关。结论:自结扎托槽与常规托槽在不拔除牙位的情况下均可导致牙弓扩张和牙尖。牙列扩张导致第一磨牙门牙和中颊根的水平和垂直骨丢失。治疗前较薄的bt和更严重的拥挤导致颊骨丢失的风险增加。

Maxillary Buccal Alveolar Bone Assessment Following Orthodontic Alignment Without Extractions (Cone beam study)
: Objective: Assessment of maxillary buccal alveolar bone following orthodontic alignment without extractions.(Cone beam study). Materials and Methods: Twenty adolescents with crowded permanent dentitions were treated without extractions with EASY SMILE (USA) Orthodontic self-ligating bracket brackets & conventional brackets. Cone beam computed tomographic scans were taken before treatment (T0) and after alignment (T1). Alveolar bone thickness (BT) was evaluated at the maxillary central incisor (I), second premolar (2PM), and first molar mesiobuccal (mb1M) and distobuccal (db1M) roots. Correlations between alveolar width changes and initial arch width, initial crowding, amount of expansion, amount of tipping, and amount of molar rotation were calculated were calculated. All data collected will be tabulated and statistically analyzed. Results: BT decreased and BH increased significantly for the incisors and mesiobuccal(mb1M) root of the first molars. Also, arch dimensions generally increased together with tipping. Bone loss was correlated with crowding and amount of expansion in the premolar region. Conclusion: Nonextraction alignment resulted in arch expansion associated with tipping of teeth for both self-ligating brackets & conventional brackets. Alignment with expansion led to horizontal and vertical bone loss at the incisors and mesiobuccal root of the first molars. Thinner BTs and more severe crowding before treatment led to increase the risk for buccal bone loss.
