OBJECTIVE
The aim of this study was to evaluate and compare dental and skeletal changes in surgically assisted rapid palatal expansion (SARPE) patients with (+PP) and without (-PP) pterygomaxillary disjunction.
STUDY DESIGN
The study casts of 18 maxillary constriction patients indicated for SARPE formed the sample of this retrospective review. The sample was divided into 2 groups. Twenty linear and 2 angular measurements were performed on the study models.
RESULTS
All transversal measurements increased after expansion in both the +PP and -PP groups. The -PP group showed greater expansion at the midpalatal and gingival levels, while the +PP group exhibited a greater increase of 0.78 mm at the apical base level and 11.25° less tipping in the molar teeth. A greater expansion of nearly 0.7 mm was measured in the premolar region of the +PP group.
CONCLUSIONS
Both SARPE techniques resulted in significant maxillary expansion.
目的
本研究旨在评估和比较伴有（+PP）和不伴有（-PP）翼钩分离的手术辅助快速腭扩张（SARPE）患者的牙齿和骨骼变化。
研究设计
本回顾性研究的样本由 18 名需要 SARPE 的上颌狭窄患者的研究模型组成。该样本分为两组。在研究模型上进行了 20 个线性和 2 个角度测量。
结果
在扩张后，+PP 和 -PP 两组的所有横向测量值均增加。-PP 组在中腭和牙龈水平显示出更大的扩张，而 +PP 组在根尖基底部增加了 0.78 毫米，磨牙倾斜角度减少了 11.25°。+PP 组的前磨牙区域测量值扩张了近 0.7 毫米。
结论
两种 SARPE 技术均导致明显的上颌扩张。
