Commonly used materials for fixed restorations in edentulous jaws include acrylic resins, polymerized ceramics, ceramics and zirconia, which have distinct physicochemical properties and clinical application features. The selection of these materials in clinical practice is related to the prosthodontic space, oral soft and hard tissue conditions, occlusal force, lifestyle habits, oral parafunctions, opposing dentition materials, and expectations of patients. Common mechanical complications associated with fixed restorations in edentulous jaws are cracking/chipping and abrasion of the facing materials, which can be avoided through occlusal adjustment, restoration design and processing, and the selection of appropriate restorative materials. This article reviews the characteristics, selection, and design considerations of commonly used materials for fixed restorations in edentulous jaws, as well as the causes and management of common clinical complications related to restorative materials, aiming to provide references for the selection of appropriate materials in fixed restorations for edentulous jaws in clinical practice.
无牙颌固定修复常用材料包括丙烯酸树脂、聚合陶瓷、陶瓷和氧化锆，它们具有不同的物理化学性质和临床应用特点。临床实践中这些材料的选择与修复空间、口腔软硬组织状况、咬合力、生活习惯、口腔副功能、对颌牙列材料以及患者期望等因素有关。无牙颌固定修复常见的机械并发症是饰面材料的开裂/崩瓷和磨损，可通过咬合调整、修复体设计与制作以及选择合适的修复材料来避免。本文综述了无牙颌固定修复常用材料的特性、选择和设计考量，以及与修复材料相关的常见临床并发症的原因和处理方法，旨在为临床实践中无牙颌固定修复合适材料的选择提供参考。
