■颈椎姿势与颅面形态有关,气道,步态和身体姿势。这种姿势可能会受到功能矫治器疗法带来的下颌位置变化的影响。因此,本系统综述旨在评估在骨骼II类受试者中使用功能矫治器治疗时颈椎姿势的变化.
■在六个电子数据库中搜索研究-Medline(通过Pubmed),Cochrane图书馆,OVID,LILACS,Scopus和WebofScience进行到2024年1月18日,没有任何日期或出版语言的限制。资格筛选,研究选择,数据提取由两名评审员独立进行.采用纽卡斯尔渥太华量表和CochraneRoB2.0对纳入研究的偏倚风险进行评估。使用随机效应模型进行Meta分析,以评估可移动和固定功能矫治器的颈椎变化。
■12篇满足资格标准的文章被纳入系统评价,9篇文章被纳入荟萃分析。五项研究显示偏见的风险较低,一个是中度的,六个是高风险的。等级评估显示了低质量的证据。荟萃分析显示,上颈椎倾斜度降低了1.16°(95%CI为-2.68至0.35,I2=6%),中颈椎倾斜增加2.20°(95%CI为0.46-3.94,I2=49%),颈椎曲角增加1.60°(95%CI为0.12-3.09,I2=89%),颈椎前凸角减少1.54°(95%CI为-4.16-1.08,I2=0%)。
■使用功能性矫治器注意到颈椎的最小直立。固定功能电器比可移动功能电器发挥更大的作用。通过可移除的功能性矫治器治疗可减少宫颈高前凸。虽然这些变化很小,临床正畸医生应该意识到功能疗法也会影响颈椎姿势。由于证据的异质性和低质量,结果将被批判性地考虑。
UNASSIGNED: Cervical spine posture is related to craniofacial morphology, airway, gait and body posture. This posture may be influenced by the changes in the mandibular position brought about by functional appliance therapy. Therefore, this systematic
review aimed to assess the changes in the cervical spine posture with functional appliance treatment in Skeletal Class II subjects.
UNASSIGNED: A search of studies in six electronic databases - Medline (via Pubmed), the Cochrane Library, OVID, LILACS, Scopus and Web of Science were performed until January 18, 2024 without any restriction in date or language of publication. Eligibility screening, study selection, and data extraction were performed by two reviewers independently. The risk of bias assessment of the included studies was performed with the Newcastle Ottawa scale and Cochrane RoB 2.0. Meta-analysis was performed using random effects model for assessment of changes in the cervical spine with removable and fixed functional appliances.
UNASSIGNED: Twelve articles that satisfied the eligibility criteria were included for systematic
review and nine articles for meta-analysis. Five studies showed a low risk of bias, one as moderate and six as high risk of bias. GRADE assessment revealed a low quality evidence. Meta-analysis revealed a decrease of the upper cervical inclination by 1.16° (95 % CI of -2.68 to 0.35, I2 = 6 %), an increase of the middle cervical inclination by 2.20° (95 % CI of 0.46-3.94, I2 = 49 %), an increase in cervical curvature angle by 1.60° (95 % CI of 0.12-3.09, I2 = 89 %) and a decrease in cervical lordosis angle by 1.54° (95 % CI of -4.16 to 1.08, I2 = 0 %).
UNASSIGNED: Minimal uprighting of the cervical spine was noted with functional appliances. Fixed functional appliances exerted a greater effect than removable functional appliances. Cervical hyperlordosis was reduced with removable functional appliance treatment. Though these changes are minimal, the clinical orthodontist should be aware that functional therapy also influences cervical spine posture. Due to the heterogeneity and low quality of evidence, the results are to be considered critically.
