摘要

背景:本研究比较了在骨骼III级治疗中,带有下颌微型钢板(HE-MP)和III级弹性体的混合上颌扩张器与传统的牙载快速上颌扩张机和面罩(RME-FM)的骨骼和牙齿效果。方法:本回顾性研究包括36例骨骼III级患者。18名患者(平均年龄10.24 ± 1.31岁)用混合扩张器、两块下颌L形微型钢板和全时III级弹性体(HE-MP组)进行治疗。他们的结果与一组接受常规RME-FM治疗的患者进行了比较(n = 18;平均年龄10.56 ± 1.41年)。在治疗前(T1)和治疗后(T2)拍摄射线照片。所有患者在T1时均处于宫颈成熟期CS1-CS3。测量的结果是矢状面和垂直骨骼和牙齿头影测量的变化。结果:治疗时间约为15.5 ± HE-MP 2.8个月,11.85 ± RME-FM 3.41个月。两组均矫正了III类错牙合,并有显著变化。HE-MP组上颌骨前移较多,SNA增加4.26° ± 2.15°,而1.14° ± RME-FM组0.93(p 结论:与牙源性上颌扩大和前伸相比,使用骨锚定进行上颌扩大和后伸可显著增加骨骼效果,减少牙齿副作用。这些结果需要长期研究。

A retrospective comparison of two protocols for correction of skeletal Class III malocclusion in prepubertal children: hybrid hyrax expander with mandibular miniplates and rapid maxillary expansion with face mask.

Background: This study compared the skeletal and dental effects of a hybrid maxillary expander with mandibular miniplates (HE-MP) and Class III elastics to conventional tooth-borne rapid maxillary expander and face mask (RME-FM) in skeletal Class III treatment.

Methods: This retrospective study included 36 skeletal Class III patients. Eighteen patients (mean age 10.24 ± 1.31 years) were treated with a hybrid expander, two mandibular L-shaped miniplates and full-time Class III elastics (HE-MP group). Their results were compared to a group of patients treated with conventional RME-FM (n = 18; mean age 10.56 ± 1.41 year). Radiographs were taken before (T1) and after treatment (T2). All patients were in cervical maturation stages CS1-CS3 at T1. The measured outcomes were the changes in sagittal and vertical skeletal and dental cephalometric measurements.

Results: Treatment time was approximately 15.5 ± 2.8 months with the HE-MP and 11.85 ± 3.41 months for the RME-FM. The Class III malocclusion was corrected in both groups with significant changes. The maxilla advanced more in the HE-MP group, with an increase in SNA of 4.26° ± 2.15° compared to 1.14 ± 0.93 in the RME-FM group (p < 0.001). The effect on the mandible was similar in both groups, while the overall skeletal change was significantly greater with HE-MP, with an increase in the ANB of 5.25° ± 2.03° and a Wits appraisal increase of 6.03 ± 3.13 mm, as opposed to 2.04° ± 1.07° and 2.94 ± 1.75 mm with the RME-FM (p < 0.001). Dental changes were significantly higher with RME-FM, with an increase in incisor inclination (U1-SN) of 5.02° ± 3.93° (p < 0.001), with no significant changes in the HE-MP group. The mandibular incisors retroclined by 5.29° ± 3.57° at L1-MP with the RME-FM, while they advanced slightly with the HE-MP by 2.87° ± 5.37° (p < 0.001).

Conclusion: The use of skeletal anchorage for maxillary expansion and protraction significantly increases skeletal effects and reduces dental side effects compared to tooth-borne maxillary expansion and protraction. These results need to be investigated in the long term.

期刊介绍: Progress in Orthodontics is a fully open access, international journal owned by the Italian Society of Orthodontics and published under the brand SpringerOpen. The Society is currently covering all publication costs so there are no article processing charges for authors. It is a premier journal of international scope that fosters orthodontic research, including both basic research and development of innovative clinical techniques, with an emphasis on the following areas: • Mechanisms to improve orthodontics • Clinical studies and control animal studies • Orthodontics and genetics, genomics • Temporomandibular joint (TMJ) control clinical trials • Efficacy of orthodontic appliances and animal models • Systematic reviews and meta analyses • Mechanisms to speed orthodontic treatment Progress in Orthodontics will consider for publication only meritorious and original contributions. These may be: • Original articles reporting the findings of clinical trials, clinically relevant basic scientific investigations, or novel therapeutic or diagnostic systems • Review articles on current topics • Articles on novel techniques and clinical tools • Articles of contemporary interest
