本文作者对22例Adaptic充填后5年零8个月后的情况作了调查,结果是:充填的177个部位中有95.5%都发生了磨耗。其磨耗深度分三级,轻者深度为96μm;中度磨耗的深度为189μm;重度磨耗者深度为555μm。关于Adaptic的硬度,作者用诺氏硬度法进行了测定。其结果Adaptic的表面硬度低。关于Adaptic的磨耗,岩谷等用在水中保存的树脂作了调查。Adaptic的表面,由 The authors investigated 22 cases of Adapti Fill 5 years and 8 months later. As a result, 95.5% of the 177 Fill sites were abraded. The depth of wear is divided into three levels, the depth of light is 96μm; the depth of moderate abrasion is 189μm; the depth of severe abrasion is 555μm. The hardness of Adaptic, the authors used the Knoop hardness method was measured. As a result, Adaptic's surface hardness is low. About Adaptic abrasion, Iwatani and other stored in the water resin was investigated. Adaptic's surface, by
