为了增强上颌总义齿的抗折力,几年来我们采用尼龙网或铝网加强的简易有效措施。据四年多的临床观察,口腔粘膜无不良反应,疗效满意。尼龙网质轻,不透色,铝例质轻,易成形,操作简便,价格低廉,深受欢迎。但其生物安全性问题,有必要进行探索。本文检测铝网及尼龙网接触皮下组织的体内毒性,及其 In order to enhance the maxillary denture resistance, over the years we use nylon mesh or aluminum mesh to enhance the simple and effective measures. According to more than four years of clinical observation, no adverse reactions of oral mucosa, efficacy is satisfactory. Nylon mesh light, impermeable, lightweight aluminum, easy to shape, easy to operate, low cost, popular. However, its biosafety issues need to be explored. This article examines the in vivo toxicity of aluminum mesh and nylon mesh in contact with subcutaneous tissue, and its
