A Study of Physical Properties of Resilient Lining Materials for Denture Bases : Characteristics of polyorefin and silicone 軟質裏装材の物理的性質に関する基礎的研究 : ポリオレフィン系ならびにシリコーン系の特性について 鷹股, 哲也 落合, 公昭 各務, 篤彦 井上, 義久 倉澤, 郁文 高橋, 重雄 永沢, 栄 洞沢, 功子 soft lining material physical property polyorefin and silicone application/pdf Resilient denture base materials have been recommended to prevent excessive pressure on residual alveolar ridges and to provide a more uniform load distribution by absorbing the "mechanical shock" caused by masticatory forces. The desirable properties of resilient denture base materials and certain clinical requirements have been suggested: (1) non-irritable and non-toxic to the oral mucosa, odorless and tasteless, (2) dimensionally stable during processing and in use, (3) low water absorption, (4) high abrasion resistance, (5) permanent resilience, (6) color stability, (7) adequate bond strength to the rigid denture-base resin, (8) no adverse effects on the denture base such as distortion, loss of strength, crazing, or blanching, (9) ease of processing, finishing and polishing and (10) ease of repair. Physical and mechanical properties of resilient lining materials are very important for these suggestions and are recommended to have consistent quality in order to be used in clinics for as long as possible. The purpose of this study is to evaluate the physical properties of two soft lining materials, polyorefin and silicone. journal article 松本歯科大学学会 1992-04-30 VoR application/pdf 松本歯学 1 18 45 53 AN00232590 0385-1613 https://mdu.repo.nii.ac.jp/record/1031/files/matsumoto_shigaku_18-01-06.pdf https://mdu.repo.nii.ac.jp/records/1031 jpn
