摘要

目的:比较牙骨性和牙源性快速上颌扩弓(RME)装置对老年青少年颌面结构的短期影响:这项回顾性研究回顾了接受上颌扩弓术的患者治疗前后的侧方和后正方头颅测量图像以及正畸模型记录。研究分为两组,采用相同的上颌扩弓方案和两种不同的上颌扩弓装置:第一组包括15名采用牙骨质(混合)RME(HRME;9名女孩和6名男孩;平均年龄(16.9 ± 0.42岁)治疗的患者;第二组包括15名采用牙骨质(传统)RME(CRME;8名女孩和7名男孩;平均年龄(16.74 ± 0.54岁)治疗的患者。对治疗前后的记录进行了头型测量和正畸模型测量:结果:两组患者的骨骼和牙齿都有明显的扩张(P虽然 HRME 装置在更大程度上增加了年龄较大的青少年的鼻腔宽度,但在上颌第一磨牙处发现了更多的牙齿副作用。

Comparison of the short-term effects of tooth-bone-borne and tooth-borne rapid maxillary expansion in older adolescents.

Purpose: To compare the short-term effects of tooth-bone-borne and tooth-borne rapid maxillary expansion (RME) devices on dentofacial structures in older adolescents.

Methods: The retrospective study reviewed pre- and posttreatment lateral and posteroanterior cephalometric images and orthodontic model records of patients who underwent maxillary expansion. Two groups were formed, in which the same upper jaw expansion protocol was applied with two different maxillary expansion devices: the first group consisted of 15 individuals treated with tooth-bone-borne (hybrid) RME (HRME; 9 girls and 6 boys; mean age, 16.9 ± 0.42 years) and the second group consisted of 15 individuals treated with tooth-borne (conventional) RME (CRME; 8 girls and 7 boys; mean age, 16.74 ± 0.54 years). Cephalometric and orthodontic model measurements were conducted on the records taken before and after treatment.

Results: Significant skeletal and dental expansions were observed in both groups (p < 0.05). However, the increase in nasal width measurements in the HRME group (2.24 ± 0.61 mm) was significantly higher than the increase in the CRME group (1.12 ± 0.25 mm; p < 0.01). Buccal tipping of the premolars was significantly less in the HRME group (0.46 ± 0.35°) than in the CRME group (2.46 ± 0.63°; p < 0.01). The amount of tipping of the molars was higher in the HRME group (4.76 ± 0.88°) compared to the CRME group (2.9 ± 1.03°; p < 0.01).

Conclusion: Although the HRME device increase the nasal width in older adolescents to a greater extent, more dental side effects were seen at the maxillary first molars.

期刊介绍: The Journal of Orofacial Orthopedics provides orthodontists and dentists who are also actively interested in orthodontics, whether in university clinics or private practice, with highly authoritative and up-to-date information based on experimental and clinical research. The journal is one of the leading publications for the promulgation of the results of original work both in the areas of scientific and clinical orthodontics and related areas. All articles undergo peer review before publication. The German Society of Orthodontics (DGKFO) also publishes in the journal important communications, statements and announcements.
