The development of protective mouthguards resulted from extensive injuries during participation in contact sports. This has produced a dramatic decrease in the incidence of injuries to the orofacial complex. Numerous materials and techniques have been used for mouthguard fabrication. The purpose of this investigation was to make an in vivo comparison of various thermoplastic mouthguard materials. Mouthguards were fabricated upon maxillary models of 40 members of the UCLA football team. The mouthguards were made of the following materials: poly (vinyl acetate-ethylene) copolymer clear thermoplastic; polyurethane; and laminated thermoplastic. Eleven measurements were taken for each mouthguard to demonstrate dimensional changes that occurred with wear. Statistical analyses determined differences between the types of mouthguards. The clear thermoplastic revealed less dimensional change than the polyurethane material. The laminated thermoplastic showed significantly less dimensional change than the other materials tested.
防护牙套的发展源于参与接触性运动时出现的大量损伤。这使得口面部复合体损伤的发生率大幅下降。众多材料和技术已被用于制作牙套。本研究的目的是对各种热塑性牙套材料进行体内比较。根据加州大学洛杉矶分校橄榄球队40名队员的上颌模型制作了牙套。这些牙套由以下材料制成：聚（醋酸乙烯酯-乙烯）共聚物透明热塑性材料；聚氨酯；以及层压热塑性材料。对每个牙套进行了11次测量，以证明佩戴时发生的尺寸变化。统计分析确定了不同类型牙套之间的差异。透明热塑性材料的尺寸变化比聚氨酯材料小。层压热塑性材料的尺寸变化明显小于所测试的其他材料。
