选择3种不同种植体采用即刻和延期两种方式植入5只狗的下颌前磨牙及第一磨牙区内,呈半负荷状态,分别于术后 2.4.6.8.12.24周取出标本作X线.LM SEM观察,结果显示:3个月时所有种植体均已达到完善骨整合,成骨量和骨小梁排列方向与(牙合)力负荷一致,且在同一机体上,骨整合无显著性差异,不同种值体之间8周时骨整合己无差异. Three different kinds of implants were implanted into the mandibular premolar and the first molar of the five dogs by both immediate and delayed implantation at half load. The specimens were taken for X-ray at 2.4.6.8.12.24 weeks after operation. LM SEM, the results showed that: all implants had achieved perfect osseointegration at 3 months, the amount of bone formation and the direction of trabecular arrangement were consistent with those of (occlusal) force, and in the same body, there was no significant difference in osseointegration Differences, different species of body value between the eight weeks no difference in bone integration.
