直到最近，牙医通常被限制为义齿患者选择瓷牙或丙烯酸树脂牙。义齿的磨损一直是牙科患者和牙科医生关注的问题。义齿的磨损可能会导致义齿在美学上和功能上不可接受。Schuyler指出，快速的咬合磨损严重影响了咬合的垂直尺寸、牙齿关系和咀嚼效率，并导致水平应力增加和相关的后遗症。假牙的磨损可能会导致相反的天然牙齿萌出。最后，由于义齿磨损导致的力不平衡可能会导致固位力的丧失，鼓励骨吸收，并导致义齿基托的断裂。2丙烯酸树脂义齿的使用受到了批评，因为与牙科瓷器相比，它们表现出更快的咬合磨损。临床和实验室研究证明，与丙烯酸树脂义齿相比，烤瓷义齿具有更好的耐磨性。3-1“一种新的改进型丙烯酸树脂义齿，Trubyte BioForm IPN(Dentsply International，Inc.，York，PA)，作为传统丙烯酸树脂和牙科瓷器的替代品被推出。IPN义齿是一种无填充物、高度交联的共聚物，具有相互穿透的聚合物网络，与传统的丙烯酸树脂牙齿中使用的传统聚合物相关但又不同。“最近的一项临床研究比较了IPN义齿和丙烯酸树脂义齿的磨损情况。12作者发现IPN义齿的耐磨性明显高于丙烯酸树脂义齿。
U ntil recently, dentists have generally been restricted to selecting either porcelain or acrylic resin teeth for denture patients. Wear of artificial teeth is of concern to dental patients and dentists. Wear of denture teeth can cause a denture to be esthetically and functionally unacceptable. Schuyler’stated that rapid occlusal wear seriously affects vertical dimension of occlusion, tooth relationships and masticatory efficiency, and results in increased horizontal stresses and associated sequellae. Wear of denture teeth may permit the supraeruption of opposing natural teeth. Finally, force imbalance due to wear of denture teeth may contribute to loss of retention, encourage bone resorption, and contribute to the fracture of the denture base. 2The use of acrylic resin denture teeth has been criticized because they exhibit rapid occlusal wear compared with dental porcelain. Clinical and laboratory studies have documented the superior wear resistance of porcelain compared with acrylic resin denture teeth. 3-1” A new improved acrylic resin denture tooth, Trubyte Bioform IPN (Dentsply International, Inc., York, Pa.), has been introduced as an alternative to the conventional acrylic resin and dental, porcelain. The IPN denture tooth is a nonfilled, highly cross-linked copolymer with an interpenetrating polymer network that is related to but distinct from traditional polymers used in conventional acrylic resin teeth.” A recent clinical study compared the wear of IPN and acrylic resin denture teeth. 12 The authors found IPN denture teeth to be significantly more resistant to wear than acrylic resin teeth.
