摘要
目的比较使用可摘前牙咬合平面(RABP)矫正生长期患者深咬合的两种方案的有效性:进餐时佩戴矫治器的全时佩戴方案(F + M)与进餐时关闭矫治器的全时佩戴方案(F - M),并探讨按佩戴方案分层的日平均佩戴时间与过度咬合(OB)矫正率之间的关系:32名生长发育中的深咬合患者(平均年龄为10.94 ± 2.17岁)被随机分配到 "F + M "组(16人)或 "F - M "组(16人)。分别在基线(T0)和达到正常 OB 时(T1)拍摄头影照片。矫治器内的 TheraMon 微型传感器记录佩戴时间。结果表明,两组患者的基线特征相似,矫治器的佩戴时间也相似:两组的基线特征和头测量变化相似,即两个牙弓的臼齿挤出、切牙内收和前倾(P < .05),组间差异不显著。与 F - M 相比,F + M 的深咬合矫正率(1.83 ± 1.18 vs 1.08 ± 0.62 mm/月;P < .05)和下颌臼齿挤压率(0.46 ± 0.25 vs 0.30 ± 0.18 mm/月;P < .05)明显更快。F + M(R2 = 0.53)和 F - M(R2 = 0.74)的每日戴用时间与外展位矫正率之间关系的最佳拟合回归模型均为指数型:在此,F + M 和 F - M 方案在深咬合生长期患者中产生的头测量变化具有可比性。然而,F + M 组的矫正速度更快。每日戴用时间与OB矫正率呈指数正相关。
Effectiveness of removable anterior bite planes with varied mealtime protocols in correcting deep bites among growing patients: a randomized clinical trial.
Objectives: To compare effectiveness of two protocols for correcting deep bite in growing patients using a removable anterior bite plane (RABP): full-time wear with appliance on during meals (F + M) vs off during meals (F - M) and to explore the relationship between average daily duration of wear and overbite (OB) correction rate, stratified by the wear protocol.
Materials and methods: Thirty-two growing patients with deep bite (mean age = 10.94 ± 2.17 years) were randomly assigned to the F + M (n = 16) or F - M (n = 16) group. Cephalometric radiographs were taken at baseline (T0) and when normal OB was achieved (T1). Duration of wear was recorded by a TheraMon microsensor within the appliance. A best-fit regression model for the relationship between daily duration of wear and OB correction rate was determined (α = 0.05).
Results: Both groups exhibited similar baseline characteristics and cephalometric changes, ie, molar extrusion, and incisor intrusion and proclination in both arches (P < .05), and intergroup differences were not significant. Here, F + M exhibited significantly faster rates of deep bite correction (1.83 ± 1.18 vs 1.08 ± 0.62 mm/month; P < .05) and mandibular molar extrusion (0.46 ± 0.25 vs 0.30 ± 0.18 mm/month, P < .05) compared with F - M. Best-fit regression models for relationship between daily duration of wear and OB correction rate were exponential for both F + M (R2 = 0.53) and F - M (R2 = 0.74).
Conclusions: Here, F + M and F - M protocols resulted in comparable cephalometric changes among deep bite growing patients. However, the F + M group exhibited a faster correction rate. Daily duration of wear positively correlated with OB correction rate in an exponential manner.
