Abstract: Full arch prosthesis is the most common modality for edentulous patients with fixed implant-supported restoration. The prosthesis is usually composed of framework and veneering layer. Metal，zirconia and non-metal polymer are the most commonly used materials for framework fabrication，and acrylic，polymer ceramic and ceramic for veneering layer. The manufacturing performance，mechanical property，biocompatibility，and clinical performance are variable. Personality treatment planning should be given with thoroughly consideration both on the patient and restorative material.

摘要： 一段式修复体为全口种植固定修复最常用的上部修复方式，上部修复体一般可分为支架和饰面材料两部分，常用的支架材料包括金属、氧化锆、非金属化合物等，常用的饰面材料包括丙烯酸树脂、聚合瓷，饰面瓷等。不同材料在加工性能、机械性能、生物相容性、长期稳定性等方面各具特点，临床表现也各不相同。医生应熟知每种材料的特性及其加工工艺，结合患者的种植体数目及分布、咬合力大小、美观需求等自身情况，为患者制定个性化上部修复材料选择方案。
