Abstract

Background and objective: Skeletal Class II malocclusion patients frequently exhibit an extended craniocervical position. The study's objective was to evaluate how the craniocervical posture has changed following skeletal class II correction using the Forsus fatigue-resistant device (FFRD).

Methodology: A retrospective analysis was undertaken using the pre- and post-treatment records of 35 skeletal class II patients who used the FFRD to achieve class II correction. The metrics suggested by Solow and Rocabado were used to evaluate the cranial and cervical positions. Eleven angular parameters were evaluated to determine the relationship between the mandibular ramus and the skull as well as the upper and middle craniocervical positions. To compare the parameters before and after fixed functional therapy, a Wilcoxon signed rank test was used.

Results: Significant differences were obtained in the parameters SNA, SNB, and ANB post-FFRD. Significant differences were also noted in NL/OPT, NSL/OPT, FH/CVT, FH/OPT, NSL/CVT, NL/CVT, ML/CVT, FH/RL, and oropharynx position.

Conclusions: The upper and middle craniocervical posture altered significantly with the FFRD. Skeletal class II correction obtained with FFRD delivered the patients a more erect craniocervical posture.

forsus辅助下颌骨进位对颅颈体位适应的影响-一项回顾性研究。
背景和目的:骨骼II类错颌患者经常表现为颅颈位延伸。该研究的目的是评估使用Forsus抗疲劳装置(FFRD)进行骨骼II级矫正后头颈部姿势的变化。方法:回顾性分析35例使用FFRD实现II级矫正的骨骼II级患者的治疗前后记录。使用Solow和Rocabado提出的指标来评估颅位和颈椎位。评估了11个角度参数,以确定下颌分支与颅骨之间的关系以及上、中颅颈位置。为了比较固定功能治疗前后的参数,采用Wilcoxon符号秩检验。结果:ffrd后SNA、SNB、ANB参数有显著性差异。NL/OPT、NSL/OPT、FH/CVT、FH/OPT、NSL/CVT、NL/CVT、ML/CVT、FH/RL、口咽部位置也存在显著差异。结论:上、中颅颈体位随FFRD发生明显改变。通过FFRD获得的骨骼II级矫正为患者提供了更直立的颅颈姿势。
