Pathogenic link of dentofacial abnormalities with posture disturbance and vertebra deformation causes interest in researchers, because the problem of the disorder of skeletal system has an important role. Orthodontic correction of dentofacial abnormalities without treatment of skeletal apparatus is incorrect and it leads to the large number of relapses and complications and also including temporo-mandibular joint. The aim of the research was to study correlation between injuries of hard tissues of teeth, posture disorders, bite abnormalities (malocclusion) in schoolchildren with hearing disorders.
The condition of hard tissues of teeth, muscoskeletal system, dentofacial system in pupils with hearing impairment was done and evaluated. The age of examined is 6-19 years old, bite formation: 1st – presents the period of mixed bite (6-13 years old), 2nd – presents the period of permanent bite (14-19 years old).
Results and conclusions: During dental examination it was detected that 58 pupils with hearing disorders (81,8%) have carious lesions of the teeth, the level of caries intensity contains 3,36. The condition of skeletal system was investigated in 56 pupils (36 boys and 20 girls). Disturbances of skeletal system in schoolchildren with hearing disorders presented 94,74%; 5,26% of pupils were almost healthy. The condition of the bite was examined in 58 pupils (32 boys and 26 girls). Different types of disorders of dentofacial apparatus were detected in 100% of pupils with hearing disorders. The most widespread pathology of bite was Angle’s bite (the first class) 68,97%, the second class – in 27,58%, the third class – 3,45%. Orthognathic bite among pupils with hearing disorders was not observed. In 31,15% of pupils during temporo-mandibular joint, deviation of mandible is observed.
牙颌面异常与姿势紊乱及椎体变形之间的致病联系引起了研究人员的关注，因为骨骼系统紊乱问题具有重要作用。在不治疗骨骼结构的情况下对牙颌面异常进行正畸矫正的做法是不正确的，这会导致大量复发和并发症，还包括颞下颌关节问题。本研究的目的是探讨听力障碍学童牙齿硬组织损伤、姿势紊乱与咬合异常（错牙合）之间的相关性。
对听力受损学生的牙齿硬组织、肌肉骨骼系统和牙颌面系统状况进行检查和评估。受检者年龄为6至19岁，咬合形成情况：第一阶段为混合牙列期（6至13岁），第二阶段为恒牙列期（14至19岁）。
结果与结论：在牙科检查中发现，58名听力障碍学生（81.8%）有牙齿龋损，龋病强度水平为3.36。对56名学生（36名男生和20名女生）的骨骼系统状况进行了调查。听力障碍学童骨骼系统紊乱的比例为94.74%；5.26%的学生几乎健康。对58名学生（32名男生和26名女生）的咬合情况进行了检查。100%的听力障碍学生存在不同类型的牙颌面装置紊乱。最常见的咬合病理类型是安氏Ⅰ类咬合（68.97%），Ⅱ类咬合占27.58%，Ⅲ类咬合占3.45%。未观察到听力障碍学生中有正颌咬合情况。在31.15%的学生中观察到颞下颌关节处下颌偏斜。
