Tooth wear is a multifactorial condition and the term is used to describe all types of non-carious tooth substance loss: abrasion (produced by interaction between the teeth and other substances), attrition (produced during tooth-to-tooth contact), erosion (produced by a chemical process) and abfraction (produced through abnormal occlusal loading that predisposes tooth substance to mechanical and chemical wear). Dental technology has an important role in preventing, managing and monitoring tooth wear in a variety of ways. Hard poly(methyl methacrylate) or soft ethylene-vinyl acetate splints can be prescribed to alleviate bruxism, the most common cause of attrition. Thermoformed appliances can be used for the application of products that reduce dental erosion such as fluoride gel. Patients with significant tooth surface loss may require laboratory-made restorations, as well as removable appliances with bite planes that generate inter-occlusal space to facilitate restorations, or surgical templates to provide guidance in preparing restorations for those requiring surgical crown lengthening. Dental study models and digitised models can also prove valuable in terms of monitoring the condition. This paper presents a review of the role that dental technology plays in tooth wear prevention, management and monitoring.
牙齿磨损是一种多因素导致的状况，该术语用于描述所有类型的非龋性牙体组织丧失：磨耗（由牙齿与其他物质相互作用产生）、磨损（在牙齿与牙齿接触过程中产生）、酸蚀（由化学过程产生）以及楔状缺损（由异常咬合负荷导致牙体组织易遭受机械和化学磨损而产生）。牙科技术在以多种方式预防、管理和监测牙齿磨损方面发挥着重要作用。可以开具硬质聚甲基丙烯酸甲酯或软质乙烯-醋酸乙烯酯夹板来缓解磨牙症，磨牙症是磨损最常见的原因。热成型矫治器可用于涂抹减少牙齿酸蚀的产品，如氟凝胶。牙面严重丧失的患者可能需要实验室制作的修复体，以及带有咬合平面的可摘矫治器，以产生牙合间间隙便于修复，或者需要手术模板，为那些需要进行外科牙冠延长术以制备修复体的患者提供指导。牙科研究模型和数字化模型在监测病情方面也可能很有价值。本文综述了牙科技术在牙齿磨损预防、管理和监测中所起的作用。
