骨性Ⅱ类错(牙合)畸形颌骨生长模式与上气道相关研究
Evaluation of pharyngeal space in different growth pattern of Class Ⅱ skeletal malocclusion
摘要
Abstract
Objective To assess whether morphology and dimension of pharyngeal airway is different in untreated skeletal Class Ⅱ subjects with normal facial pattern characterized by various growth patterns of maxilla and mandible.Methods Fourty young men's CBCT of Class Ⅱ malocclusion with normal facial vertical pattern were selected from February 2015 to March 2016 in Urumqi Stomatological Hospital Orthodontic Division.The 78.5° ≤SNA≤86.8° was regarded as normal maxilla and 76.2° ≤ SNB ≤ 84° as normal mandible,and the samples were accordingy divided into four groups:12 cases in normal group (group A),10 cases in retrognathic mandible with normal maxilla group (group B),9 cases in prognathic maxilla with normal mandible group (group C),9 cases in retrognathic double jaw group (group D).Analyze the pretherapeutic cone-beam computed tomography(CBCT)scans.Results There was significant difference in the linear measurements in different groups,including∠ ANB,∠ FMA,∠ ANS-PNS to P,adl-PNS,ad2-PNS,ANS-PNS to PPW,AAO-PNS,P-PP,PH-PPH,P-SN,M-SN,the mandible length and the somatic part of mandible length,and the difference was statistically significant.The comparison results among groups also had difference,and the difference had statistical significance.Conclusion A significant relation exists between oropharynx pattern and the sofi palate pattern and growth pattern of maxilla and mandible with normal facial vertical pattern in Class Ⅱ subjects.According to various growth patterns,different growth modification appliance can be used to improve the pharyngeal airway.关键词
