近年来,随着口腔种植材料研究的不断发展,要求研究手段也要随之更新。要观察种植材料与组织之间的结合关系,需要制出良好的切片。脱钙切片会使植入材料经酸处理后脱落;直接磨片法则容易破坏组织间结构,特别易损坏软组织。我们经过不断摸索,采用复合材料包埋的磨片技术,得到了满意的效果。1材料和方法1.1标本植有颗粒型复合生物陶瓷和颗粒型微密多晶羟基磷灰石的动物(猴、犬),牙周骨缺损修复标本6例。植有块状复合生物陶瓷
In recent years, with the continuous development of oral implant material research, research tools also need to be updated. To observe the binding relationship between the planting material and the tissue, it is necessary to make a good slice. Decalcified slices will implant material after acid off; direct grinding method is easy to destroy the inter-organizational structure, especially vulnerable to soft tissue. We have been groping, the use of composite materials embedded in the grinding technology, has been satisfactory results. 1 Materials and methods 1.1 Specimens with granular composite bioceramics and granular polycrystalline hydroxyapatite animals (monkeys, dogs), periodontal bone defect repair specimens in 6 cases. Planting a massive composite bio-ceramic
