摘要:

目的 探讨个性化微螺钉辅助成人腭中缝快速扩弓对髁突位置的影响。方法 采用回顾性研究的方法,对 10 例成年且患有上颌横向发育不足的患者,使用个性化微螺钉辅助快速扩弓器进行扩 弓治疗,分别于扩弓前(T0)、扩弓后(T1)以及保持 3 个月后(T2)行锥形束 CT(CBCT)检查,并对相关髁突位 置参数进行测量、对比。应用 SPSS 21.0 软件进行统计学分析。结果 扩弓后(T1)左侧颞下颌关节上间隙 增加(0.31 ± 0.24)mm,右侧为(0.54 ± 0.41)mm;左侧颞下颌关节后间隙增加(0.77 ± 1.01)mm,右侧增加 0.49 ± 0.46)mm;左侧颞下颌关节外间隙增加(0.31 ± 0.40)mm,右侧增加(0.41 ± 0.34)mm;而双侧颞下颌 关节内间隙变窄左侧⁃(0.56 ± 0.65)mm,右侧⁃(0.49 ± 0.28)mm,差异均有统计学意义(P < 0.05),扩弓三个月后(T2)仍保持同样的变化;扩弓前(T0)、扩弓后(T1)以及保持 3 个月后(T2)双侧颞下颌关节半径及髁突 水平角变化差异无统计学意义(P > 0.05)。结论 个性化微螺钉辅助成人腭中缝快速扩弓会引起双侧髁 突位置发生适当的前下改变,有利于矫治效果的稳定。

Abstract:

Objective To investigate the effect of expanding midpalatal suture in adults by personalized miniscrew⁃assisted rapid palatal expander on condylar position. Methods Ten adult patients with maxillary trans⁃ verse deficiency were expanded using a personalized miniscrew⁃assisted rapid palatal expander. The relative posi⁃ tion parameters of temple mandible joint were measured and contrasted before expansion(T0),after expansion (T1)and after retention for three months(T2)on CBCT. A statistical analysis was completed with the SPSS 21.0 software. Results The superior space(SS),posterior space(PS)and lateral space(LS)of temple mandible joint became wider and the medial space(MS)became smaller after rapid expanding of midpalatal suture,suggesting there were statistic differences(P < 0.05),which maintained the same changes after expansion for three months whereas there were no statistical significances in radius of temple mandible joint and horizontal angle of condyle on both sides(P > 0.05). Conclusions Expanding midpalatal suture in adults by personalized miniscrew ⁃assisted rapid palatal expander can cause bilateral condyle position an appropriate antero⁃inferior change,which is benefi⁃cial to the stability of correction results.
