The recommendation to use pin implants as fixing elements in horizontally fractured roots of anterior teeth is based on our own animal experiments as well as on clinical and radiological examinations of six patients. The examinations were made in 14 anterior teeth fixed to the bone by a pin the roots of which had been reduced to about half the physiologic length by resorption, amputation or fracture. The original biomechanical situation was the same in all three types of root reduction. We observed the pin-fixed teeth for 2 1/2 years on the average.
将针形种植体用作前牙水平折断牙根固定元件的建议是基于我们自己的动物实验以及对六名患者的临床和放射学检查得出的。这些检查是在14颗通过针固定于牙槽骨的前牙上进行的，这些牙齿的牙根因吸收、截根或折断已缩短至生理长度的约一半。在所有三种牙根缩短类型中，最初的生物力学状况是相同的。我们平均观察针固定牙2年半。
