将牙汞合金和瓷对照盘植入大鼠皮下组织。汞合金植入物的毒性作用是由金属离子释放引起的，其特征是炎症延长，肉芽形成延迟，胶原蛋白形成紊乱。牙瓷被发现是一种合适的生物相容性对照，它提供了类似于牙汞合金的体积，但只引起简单的肉芽反应。
Dental amalgam and porcelain control discs were implanted in the subcutaneous tissue of rats. Amalgam implants exerted a toxic effect caused by release of metal ions which was characterized by prolonged inflammation, delayed granulation and disordered collagen formation. Dental porcelain was found to be a suitable biocompatible control which provided a bulk similar to that of dental amalgam but induced only an uncomplicated granulation response.
