牙体缺损1(Tooth Defect定义(conception 由于各种原因引起的牙体硬组织不同程度的外形和结构的破坏,造成形态、咬合或邻接关系的异常Tooth defect means different extent ofdefect or the abnormality of structure and thephysical anatomic contour of the dental hardtissue ,namely, defect of normal dentalconfiguration, occlusive relationship andproximal relationship

牙体缺损( Tooth Defect ) 定义(conception) 由于各种原因引起的牙体硬组织不同程 度的外形和结构的破坏,造成形态、咬合 或邻接关系的异常。 Tooth defect means different extent of defect or the abnormality of structure and the physical anatomic contour of the dental hard tissue ,namely, defect of normal dental configuration, occlusive relationship and proximal relationship
