Forty-five cobalt-chromium alloy porous rooted dental implants were placed in dogs. They were evaluated periodically over two years. The implants were successful one-third of the time. Failures occurred early (two months) or late (after six). Attempts to explain the failures, early and late, are made.
将45颗钴铬合金多孔牙根种植牙植入狗体内。在两年时间里对它们进行定期评估。这些种植牙有三分之一的成功率。失败情况出现得较早(两个月后)或较晚(六个月后)。本文尝试对早期和晚期的失败原因进行解释。
