【摘要】 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。更多还原

【Abstract】 Objection:To study the occlusion type and tooth contact relationship of lateral occlusion to provide basic knowledge for clinic occlusion. Material and methods:The observation was made on 146 sutdents. Results:Group functional occlusion is the most among the three kinds of occlusion(45.21%), the second is canine protected occlusion(34.25%), the third is mixed type(20.54%); there are seven kinds of tooth. Contact relationship in group functional occlusion, 34563456 is more than any other kind. Conclusion: The sequence of three kinds occlusion type is group functional occlusion, canine protected occlusion and mixed type according to their occurrence rate when lateral occlusion. There are seven kinds of relationship of tooth contact.更多还原
