摘要: 目的:评估时代天使和隐适美两种矫治系统治疗前牙深覆牙合的实现率及其影响因素。方法:纳入76例采用无托槽隐形矫治器治疗深覆牙合的患者,使用三维扫描仪获取数字模型,通过最佳拟合重叠模型,评估两种隐形矫治器治疗深覆牙合的实现率,并采用多因素线性回归分析其相关影响因素。结果:隐适美和时代天使平均覆牙合减少量和实现率分别为1.42 mm(39.32%)和0.84 mm(25.40%),预测覆牙合变化量与两种矫治器治疗深覆牙合的实现率呈负相关性;压低上颌中切牙的实现率分别为12.14%(隐适美)和8.96%(时代天使),上颌中切牙预测压低量(隐适美)和是否有支抗钉压低牵引(时代天使)对其有显著影响。结论:两种矫治器均能有效减少覆牙合,隐适美治疗深覆牙合和压低上颌中切牙的实现率更高。隐形矫治器在治疗深覆牙合时,预测覆牙合变化量越小,实现率越高;增加压低支抗钉的使用和降低上颌中切牙预测压低量,压低上颌中切牙的实现率更高。

Abstract: Objective: To evaluate the achievement rates of Angelalign and Invisalign in treating anterior deep overbite and identify related influencing factors. Methods: Seventy-six patients with deep overbite treated with clear aligners were enrolled. Digital models were acquired via 3D scanning, and treatment outcomes were assessed using best-fit superimposition. Multivariate linear regression analyzed associated factors. Results: Invisalign and Angelalign achieved overbite reductions of 1.42 mm (39.32%) and 0.84 mm (25.40%) respectively, with realization rates negatively correlated to predicted overbite changes. The realization rates for maxillary central incisor intrusion were 12.14% (Invisalign) and 8.96% (Angelalign), respectively. Predicted intrusion magnitudes (Invisalign) and the use of temporary anchorage devices for intrusive traction (Angelalign) significantly influenced these rates. Conclusion: Both aligners effectively reduced overbite, with Invisalign showing higher realization rates for deep overbite correction and maxillary central incisor intrusion. For deep overbite correction, smaller predicted overbite changes were associated with higher realization rates. Regarding maxillary central incisor intrusion, increased use of temporary anchorage devices (Angelalign) and reduced predicted intrusion magnitudes (Invisalign) improved realization rates.
