摘要： A denture comprising teeth consisting essentially of hard non-hydrophilic polyurethane elastomer imbedded in and chemically bonded to a gum member consisting essentially of soft non-hydrophilic polyurethane elastomer is prepared from a model assembly consisting of a wax replicate denture (artificial teeth imbedded in a wax pattern) mounted on a mouth model which assembly is usually provided by a dentist or dental technician after a series of dental impressions, bites, and trials with the patient. A female mold is prepared from the model assembly having a cavity conforming to the wax replicate denture which, together with the mouth model after the wax replicate denture has been removed, forms a denture mold. The hard non-hydrophilic polyurethane elastomer teeth are first cast in the cavity of the mold. The casting is then removed and trimmed of its flash down to the gum line to delineate the shape of that portion of the teeth to be imbedded in the gum portion of the denture and replaced in the mold. The gum portion of soft non-hydrophilic polyurethane elastomer is then cast in and around the teeth with the mouth model in place, thereby forming a denture having exactly the same shape and configuration of the wax replicate denture originally provided.

摘要： A denture consisting of teeth anchored in a gum member composed of a unitary mass of non-hydrophilic polyurethane elastomer, the tooth-holding portion of which is hard and the mouth-engaging portion of which is soft is prepared by first casting the teeth-holding portion about the teeth and then casting the gum holding portion onto the tooth-holding portion and curing the denture during which the gum-engaging portion and the tooth-holding portion become integrally chemically bonded into a unitary mass.

摘要： A hard, substantially non-hydrophilic polyurethane elastomer denture is disclosed in which the elastomer possesses a hardness of not less than about Shore D60 and preferably not greater than about Shore D100. The polyurethane elastomer is prepared from a polyether polyol and an aromatic polyisocyanate in which the isocyanate groups are bonded directly to the aromatic nucleus. The aforesaid hard non-hydrophilic polyurethane elastomer can constitute the entire material of which the denture is made, including the teeth if so desired, or it can be employed as the tooth-holding portion of the denture in combination with a soft, substantially non-hydrophilic elastomer as the mouth-engaging portion of the denture. The hard non-hydrophilic polyurethane elastomer possesses superior resistance to thermal distortion under the conditions prevailing in the mouth.
摘要翻译：公开了一种硬的，基本上非亲水的聚氨酯弹性体义齿，其中弹性体具有不小于约肖氏D60的硬度，优选不大于约肖氏D100。聚氨酯弹性体由聚醚多元醇和芳族多异氰酸酯制备，其中异氰酸酯基团直接键合到芳族核上。上述硬质非亲水性聚氨酯弹性体可以构成义齿的整个材料，如果需要，包括齿，或者它可以用作义齿的牙齿保持部分，与柔软的，亲水性弹性体作为义齿的口接合部分。硬质非亲水性聚氨酯弹性体在口腔中普遍存在的条件下具有优异的耐热变形性。
