本文对不同临床牙槽骨吸收类型作组织学定量分析。 4具尸解上颌牙槽骨与腭骨,中度吸收,无最近拔牙征象及过多松软组织,3个有戴全口义齿史。固定脱钙染色从前到后分6个区作组织学检查。骨表面分4种组织类型:吸收型、板状骨、编织骨、化生骨。据各种类型所占表面长度,计算机处理图象,作出定量分析。结果:吸收型多在牙槽嵴顶和靠近牙槽嵴唇、腭侧;板状骨主要在腭部,牙槽骨区比例较少仅占3～25%;编织骨是不成熟骨,在牙槽骨顶占比例较多,有1例为85%;化生骨指不正常骨有混合特点,偏光显微镜下可见胶原纤维,但缺乏典型的编织骨和板状骨,这
In this paper, different clinical alveolar bone resorption histological quantitative analysis. 4 corpse of the maxillary alveolar bone and palatal bone, moderate absorption, no signs of recent tooth extraction and excessive soft tissue, 3 have wear complete denture history. Fixed decalcification staining from before to after 6 points for histological examination. Bone surface divided into four types of tissue: Absorption, plate-like bone, braided bone, metaplastic bone. According to the various types of surface length occupied, the computer processes the image to make a quantitative analysis. Results: Absorption was mostly at the alveolar crest and near the alveolar ridge and the palatal side. The plate-shaped bone was mainly located in the palatal part and the alveolar bone area accounted for only 3-25% of the total. The braided bone was immature bone. Alveolar bone accounted for a larger proportion, 1 case was 85%; metaplastic bone refers to the characteristics of abnormal bone mixed with polarized light microscopy of collagen fibers, but the lack of typical braided bone and plate bone, which
