目的 :研究侧咬合型及牙接触关系 ,为临床应用提供基础。材料方法 :活体观察 146名青年人侧咬合型及牙齿接触关系。结果 :侧咬合时 ,型分组牙功能最多 (45 .2 1% ) ,尖牙保护次之 (34 .2 5 % ) ,混合型最少(2 0 .5 4% ) ;组牙功能时 ,上下牙接触关系分为七种类型 ,其中以34 5 634 5 6 最多 (31.0 6 % )。结论 :青年人侧咬合时以组牙功能最多 ,尖牙保护次之 ,混合型最少 ;组牙功能时 ,上下颌牙齿接触关系分为七种类型。
Objective: To study the relationship between the occlusal type and the tooth contact, and provide the basis for clinical application. MATERIALS AND METHODS: One hundred and forty-four young people were observed for occlusal occlusion and dental contact. Results: In the occlusal approach, the maxillary tooth function (45.21%), canine secondarily (34.25%) and mixed type (20.44% There were seven types of contact between the upper and lower teeth, of which 34 5 634 5 6 were the most (31.0 6%). Conclusions: When the young people engage the side bite, the maximal number of teeth in the group is occlusal, the canine protection is followed by the least, and the mixed type is the least. In the group of teeth, the contact between upper and lower jaws is divided into seven types.
