Abstract

Transmucosal application of implants of dense hydroxylapatite has been studied in a long-term animal experiment. Implants were loaded with crowns or removable restorations. It appeared that transmucosal implants adhered to bone similarly as in the submucosal application. The clinical aspect of gingival tissues around the implants was the same as that around the adjacent natural teeth. Histologically, there were indications for a good attachment of gingival tissues to the implants. Implants fractured due to fatigue failure of the ceramic material. Prestressing of the implants may be the solution to this problem. Failing implants can clinically be treated by submerging, removal, or substitution.

摘要

在一项长期动物实验中研究了致密羟基磷灰石植入物的经黏膜应用。植入物上安装了牙冠或可摘修复体。结果显示，经黏膜植入物与骨的附着情况与黏膜下应用相似。植入物周围牙龈组织的临床情况与相邻天然牙周围的情况相同。组织学上，有迹象表明牙龈组织与植入物有良好的附着。植入物因陶瓷材料的疲劳失效而断裂。对植入物进行预应力处理可能是解决该问题的方法。临床上，失败的植入物可以通过埋入、取出或替换进行治疗。
