| 摘 要： | 目的 分析楔状缺损患牙颈部硬组织的应力分布.方法 在下颌前磨牙沿釉牙本质界建立三角形缺损,设计楔状缺损模型,模拟侧方运动中牙齿的受力情况,对下颌前磨牙颈部硬组织行非线性接触分析.结果 斜向载荷下,釉牙本质界缺损的下颌前磨牙缺损区尖端存在明显的拉应力集中.随缺损高度的增加,应力值增大,应力集中程度也增加:应力集中区沿釉牙...

| Abstract: | Objective To study the distribution of stress of simulating teeth with wedge shaped defects in the cer-vical region.Methods The models of anisotropic enamel of the mandibular first premolar and the opposite maxillary first premolar crown were created.A deffect was introduced into the model of mandibular premolar in the buccal cervical region along the enamelo-dentinal junction(DEJ).The stress distribution in the cervical region of the mandibular premolar was investigated considering lateral condition simula... |
