モデリングコンパウンド印象材と新しい熱可塑性高分子印象材の特性について On the Characteristics of Modeling Compound Impressinon Materials and a New High Polymer Thermoplastic Impression Material 杉江, 玄嗣 洞沢, 功子 永沢, 栄 高橋, 重雄 橋本, 京一 平嶺, 勝嗣 外山, 恵一 金子, 万造 印象材 熱可塑性 高分子 物性 application/pdf Currently marketed modeling compound impression materials, and a new thermoplastic high polymer impression material, were compared in terms of their themoplastic characteristics, and their physical and mechanical properties. The twelve kinds of modeling compounds used included both Japanese and foreign products. The new material consists of poly capryl lactone. It must be softened at 72-82℃, but can be used for taking impressions at 48℃. It has higher compressive strength and Young's modulus, but less elasticity than conventional modeling compounds. Its thermal conductivity in low, and its specific heat high. From these factors it is concluded that the new impression material is suitable for a variety of applications including impressions for an individual tray, for complete dentures, or for determining the occlusal relation. 松本歯科大学学会 1989-12-31 jpn journal article VoR https://mdu.repo.nii.ac.jp/records/1136 AN00232590 0385-1613 松本歯学 15 3 303 309 https://mdu.repo.nii.ac.jp/record/1136/files/matsumoto_shigaku_15-03-07.pdf application/pdf 866.4 kB 2012-05-24
