Abstract：
UNASSIGNED: The mixed dentition stage in children is a critical period for orthodontic assessment and intervention. This study investigates the effects of interceptive orthodontics on dental and skeletal development in children with mixed dentition, aiming to evaluate the potential benefits of early orthodontic treatment.
UNASSIGNED: A retrospective analysis was conducted on a cohort of 150 children with mixed dentition (aged 7-11 years), who received interceptive orthodontic treatment. Dental and skeletal records, including cephalometric radiographs and dental cast models, were collected before and after treatment. A control group of 150 untreated children with mixed dentition was also assessed for comparison. Various dental and skeletal parameters, such as dental alignment, overjet (OJ), overbite (OB), and cephalometric measurements, were recorded and analyzed.
UNASSIGNED: The results of this study indicate significant improvements in dental alignment and occlusion in the group of children who received interceptive orthodontic treatment. The average reduction in OJ was 3.5 mm, and the OB correction averaged 2.1 mm. Cephalometric analysis showed positive changes in skeletal relationships, with a mean reduction in the angle formed by point A, nasion (N) and point B. (ANB) angle of 2.8 degrees. These improvements were statistically significant compared to the control group (P < 0.05).
UNASSIGNED: Early orthodontic intervention, such as interceptive orthodontics, has a positive impact on dental and skeletal development in children with mixed dentition.

摘要：
■儿童的混合牙列阶段是正畸评估和干预的关键时期。这项研究调查了拦截正畸对混合牙列儿童牙齿和骨骼发育的影响，旨在评估早期正畸治疗的潜在益处。
■对150名患有混合牙列的儿童（7-11岁）进行了回顾性分析，接受过拦截性正畸治疗的人.牙科和骨骼记录,包括头颅射线照片和牙科模型，收集治疗前后。还评估了150名未经治疗的混合牙列儿童的对照组进行比较。各种牙齿和骨骼参数，例如牙齿对齐，喷射机(OJ)，过咬合(OB),和头颅测量，进行记录和分析。
■这项研究的结果表明，在接受拦截式正畸治疗的儿童组中，牙齿对齐和咬合的显着改善。OJ的平均减少量为3.5mm,和OB校正平均2.1mm。头颅测量分析显示骨骼关系发生积极变化，点A形成的角度平均减小，nasion(N)和B点(ANB)的角度为2.8度。这些改善与对照组相比有统计学意义(P<0.05)。
■早期正畸干预，如拦截正畸，对混合牙列儿童的牙齿和骨骼发育有积极影响。
