Abstract

Aim: To evaluate and compare the dentoskeletal and soft tissue effects of the PowerScope and Twin Block appliances for treating Class II malocclusions.

Materials and methods: This retrospective study analyzed pre- (T0) and posttreatment (T1) cephalograms of 14 patients treated with PowerScope (Group A) and 17 patients treated with Twin Block (Group B). Thirty-three cephalometric variables were assessed. Statistical analysis included paired and independent t-tests or their non-parametric equivalents.

Results: Both groups showed significant improvements in soft tissue profiles. The Twin Block group demonstrated a significantly greater increase in SNB angle (p = 0.048) and more pronounced changes in UL-SnPog' and LL-SnPog' posttreatment (p = 0.021 for both). The PowerScope group exhibited significantly greater increases in IMPA and Md-NB (p = 0.029 and p < 0.001, respectively) and a significantly shorter treatment duration (p < 0.0001).

Conclusion: Both appliances effectively treat Class II malocclusion and improve lip positioning. The Twin Block appliance is associated with greater mandibular skeletal advancement, while the PowerScope appliance leads to greater lower incisor protrusion and a shorter treatment time.

PowerScope矫治器治疗ⅱ类错牙合对牙髓及软组织的影响。

目的：评价和比较PowerScope矫治器与Twin Block矫治器治疗ⅱ类错牙合的牙骨骼和软组织效果。材料与方法：回顾性分析了14例PowerScope （A组）和17例Twin Block （B组）患者治疗前（T0）和治疗后（T1）的脑电图。评估了33个头侧测量变量。统计分析包括配对和独立t检验或其非参数等效检验。结果：两组患者软组织形态均有明显改善。Twin Block组SNB角度明显增加（p = 0.048），处理后UL-SnPog‘和LL-SnPog’的变化更明显（p = 0.021）。PowerScope组IMPA和Md-NB均有显著提高（p = 0.029和p）。结论：两种矫治器均能有效治疗ⅱ类错颌，改善唇部定位。Twin Block矫治器与更大的下颌骨骼前移有关，而PowerScope矫治器导致更大的下门牙突出和更短的治疗时间。

期刊介绍： Clinical and Experimental Dental Research aims to provide open access peer-reviewed publications of high scientific quality representing original clinical, diagnostic or experimental work within all disciplines and fields of oral medicine and dentistry. The scope of Clinical and Experimental Dental Research comprises original research material on the anatomy, physiology and pathology of oro-facial, oro-pharyngeal and maxillofacial tissues, and functions and dysfunctions within the stomatognathic system, and the epidemiology, aetiology, prevention, diagnosis, prognosis and therapy of diseases and conditions that have an effect on the homeostasis of the mouth, jaws, and closely associated structures, as well as the healing and regeneration and the clinical aspects of replacement of hard and soft tissues with biomaterials, and the rehabilitation of stomatognathic functions. Studies that bring new knowledge on how to advance health on the individual or public health levels, including interactions between oral and general health and ill-health are welcome.
