Abstract

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.

摘要

将牙科汞合金和瓷质对照盘植入大鼠皮下组织。汞合金植入物因金属离子释放而产生毒性作用，其特征为炎症持续时间长、肉芽形成延迟和胶原形成紊乱。发现牙科瓷是一种合适的生物相容性对照物，它提供了与牙科汞合金相似的体积，但仅引起简单的肉芽反应。
