This is a morphlogical study of tissue remodeling aroud dental implants that were placed in distracted mandible. Three months after extraction of premolars of mandible, horizontal distraction of the alveolar ridge in dogs was performed. Alveo-Wider【○!R】 (Okada Medical Supply Co.Ltd.) was used as distracting apparatus. After completin of distraction, dental implants (Replace Select【○!R】, 3.5mm diameter, 10mm length, Nobel Biocare) were placed into the distracted areas. Three months after placement of implants, abutments and crowns were placed. Some implants were under excessive occlusal load. Implants with surrounding tissue were dissected and undecalcified sections were prepared. The sections were stained with toluidine blue and obsereved under light microscopy. Histologically, all of the implants in horizontally distracted alveolar ridges acquired osseointegration. Mobility was not detected by Periotest【○!R】.

这是一项关于放置在下颌骨中的牙种植体周围组织重塑的形态学研究。拔除下颌前磨牙三个月后，对狗进行牙槽嵴水平牵引。 Alveo-Wider【○！R】（冈田医疗用品有限公司）用作分散装置。牵引完成后，将种植牙（Replace Select【○！R】，直径3.5mm，长度10mm，Nobel Biocare）植入牵引区域。植入种植体三个月后，植入基台和牙冠。一些种植体承受过大的咬合负荷。解剖具有周围组织的植入物并制备未脱钙切片。将切片用甲苯胺蓝染色并在光学显微镜下观察。在组织学上，水平分散的牙槽嵴中的所有种植体都获得了骨整合。 Periotest【○!R】未检测到移动性。
