摘要
背景拱扩展是一种获取空间的非提取方法。本研究旨在评估和比较三种不同支架-弓丝组合在初始调平和对准过程中获得的弓扩张。材料和方法:这是一项在大学进行的回顾性研究。从现有的患者信息档案中,根据30例患者的主张支架系统,将其分为三组。使用OrthoAnalyzer软件(3 shape version 19.0),根据第三腭纹上标记的参考点,将治疗前(T0)和对齐后(T2) 3D上颌模型扫描叠加,评估齿间宽度(ICW)、前磨牙宽度(IPW)、磨牙宽度(IMW)和弓长的变化。对记录的资料采用SPSS软件进行描述性统计、单因素方差分析和Tukey HSD事后分析。结果-除了Damon组在磨牙间和前磨牙尺寸上有明显的增加外,其他组在犬齿间宽度、后磨牙宽度、磨牙间宽度和牙弓长度上没有统计学上的显著差异。结论:三组患者的横向尺寸均有明显变化,其中以Damon托槽和Damon弓丝组合的变化最大。虽然两组间牙体扩张的差异无统计学意义,但在缓解牙体拥挤方面具有临床应用价值。
Evaluation of Maxillary Transverse Arch Dimensions Following Leveling and Alignment with Different Archwire-Bracket Combinations During Fixed Appliance Treatment - A Retrospective Study
Background- Arch expansion is one of the non- extraction methods of gaining space. This study aims to assess and compare the arch expansion achieved during initial leveling and alignment with three different bracket-archwire combinations.
Material and Methods- This was a retrospective study done in a university setup. From the available patient information archives, records of 30 subjects based on their advocated bracket system were identified and categorized into three groups. Their pre-treatment (T0) and post aligning (T2) 3D model maxillary scans were superimposed according to the reference points marked on the third palatal rugae using an OrthoAnalyzer software(3 shape version 19.0) to assess the changes in Intercanine width (ICW), Inter-premolar width (IPW) and Intermolar width (IMW) and arch length. For the recorded data, descriptive statistics, One-way ANOVA and Tukey HSD post hoc were analyzed using SPSS software.
Results- Except for the Damon group that showed considerable increase in the intermolar and premolar dimensions, other groups had no statistically significant differences in terms of Intercanine width, Interpremolar width, and Intermolar width and Arch length.
Conclusion- Changes in the transverse dimension were noticed among all the three groups with maximum in the Damon bracket and Damon archwire combination. Although the difference in expansion between groups showed no statistically significant difference, it was appreciated clinically in relieving dental crowding.
