摘要

背景:目的:比较Biblock矫治器(BA)和Activator矫治器(AA)对II类错颌畸形患者的骨骼、牙槽和软组织的影响:方法:本研究纳入了35名因骨骼Ⅱ类错颌畸形和正常发育模式引起的下颌后缩患者。在筛选出BA组(n=17,8男9女,平均年龄(12.08±0.37)岁)后,我们选择了与BA组发育和性别相匹配的AA治疗积极对照组(n=18,9男9女,平均年龄(12.3±0.27)岁)。根据手腕成熟度,所有患者都处于 PP2 = DP3u 期之间。测量了与骨骼、牙槽骨和软组织相关的头颅测量变量:BA患者的治疗时间为(18.17 ± 1.45)个月,AA患者的治疗时间为(16.92 ± 1.09)个月。两组患者的骨骼二类错合畸形均有明显改善。在对比组中,AA 组的 ANS-Me 增长率明显更高(P < 0.05)。在对比组中,BA 组的 Cd⊥SN 和 S-Cd 增幅明显更高(P < 0.05)。各组之间在骨骼、牙槽和软组织测量方面没有明显差异(P > 0.05):结论:被正畸界认可的AA矫治器和新设计的BA矫治器对骨骼、齿槽和软组织的影响相似。

New Solution in the Treatment of Children with Class II Malocclusion: Biblock Appliance.

Background: A new design, the Biblock appliance, was developed for the functional treatment of Class II malocclusions.

Aim: To compare the effects of Biblock appliance (BA) and Activator appliance (AA) on the skeleton, dentoalveolar, and soft tissue in Class II malocclusions.

Methods: Thirty-five patients with mandibular retrognathia caused by skeletal Class II malocclusion and normodivergent growth pattern were included in this study. After selecting the BA group (n = 17, 8 boys and 9 girls, mean age = 12.08 ± 0.37 years), we selected the active control group treated with AA (n = 18, 9 boys and 9 girls, mean age = 12.3 ± 0.27 years), which matched the BA group's development and gender. All patients were between PP2 = DP3u periods according to hand-wrist maturation. Cephalometric variables related to the skeletal, dentoalveolar, and soft tissue were measured.

Results: Treatment duration was 18.17 ± 1.45 months with BA and 16.92 ± 1.09 months with AA. Skeletal Class II malocclusion improved significantly in both groups. In the compared groups, the increase in ANS-Me was significantly higher in the AA group (P < 0.05). The Cd⊥SN and S-Cd increase in the compared groups was significantly higher in the BA group (P < 0.05). There was no significant difference in measurements between the groups in skeletal, dentoalveolar, and soft tissue measurements (P > 0.05).

Conclusion: The effects of AA, an appliance accepted by the orthodontic community, and BA, a new design, on the skeletal, dentoalveolar, and soft tissue were similar.
