There are, however, cases when the denture-bearing area is of such a nature as to make coverage by a rigid denture intolerable to the patient. Many patients experience pain and difficulty using dentures constructed with hard denture bases. Accordingly resilient materials have been used to increase resilience during function and under pressure. The desirable properties, and certain clinical requirements, of a resilient denture base materials have been suggested : (1) non-irritant and non-toxic to the oral tissue, odorless and tasteless, (2) dimensionally stable during processing and in use, (3) low water sorption, (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. However, such an excellent material cannot be found in clinics. The purpose of this study is to evaluate the color stability of one of the resilient soft lining materials, "Molteno", for a removable prosthesis. The results were obtained as follows : (1) The values were not influenced by the three solutions, saline, turmeric, and red color No.102. (2) The hue was influenced by all solutions, and especially by olive oil which contains theβ-carotene. (3) The degree of color change differed depending on the solution.}, pages = {268--275}, title = {ポリオレフィン系軟質裏装材の基礎的検討 第2報 各種溶液における変色について}, volume = {16}, year = {1990} }
