In order to obtain a replica technique suitable for a complete or segments of a dental arch two different impression materials were combined with two epoxy resin model materials. The models were examined and photographed in an optical microscope and a scanning electron microscope. No systematic differences were found between the used combinations of materials except a tendency towards greater contraction of one of the model materials. The A-silicone impression materials combined with one of the epoxy resin material seemed to be the easiest to handle and to give the best models.
为了获得一种适用于整个牙弓或牙弓部分的复制技术，将两种不同的印模材料与两种环氧树脂模型材料相结合。在光学显微镜和扫描电子显微镜下对模型进行检查和拍照。除了一种模型材料有更大收缩的趋势外，所使用的材料组合之间未发现系统差异。A 型硅橡胶印模材料与其中一种环氧树脂材料结合使用似乎最易于操作，并能得到最佳模型。
