扫描电镜(SEM)技术自问世以采,在口腔医学领域得到广泛应用,其标本制备方法不断更新。但是制备既含有硬组织如牙、牙槽骨和种植材料,又含有软组织牙周膜和粘骨膜,并且要求在制备标本过程中不改变各种结构的位置关系,有一定难度。我们曾以 Since the advent of scanning electron microscopy (SEM) technology, it has been widely used in the field of stomatology and its specimen preparation methods are continuously updated. However, it is somewhat difficult to prepare a tissue that contains both hard tissues such as teeth, alveolar bone, and planting material, as well as soft tissue periodontal ligament and mucoperiosteum, and requires that the positional relationship of various structures should not be changed during preparation of the specimen. We used to
