The high esthetic expectations from the prosthodontic restorations have directed the qualitative development of the materials towards the all-ceramic materials that are capable of replacing porcelain-fused-to-metal systems.
This article reviews the literature covering the contemporary all-ceramic materials and systems with a focus on the chemical composition and materials' properties; also it provides clinical recommendations for their use.
The glass-matrix ceramics and polycrystalline ceramics are presented, as well as recently introduced machinable materials, all-zirconia and resin-matrix ceramics. The specific properties of zirconia, such as transformation toughening, stabilisation of the crystallographic structure, low-temperature degradation and factors affecting the zirconia's ageing, are emphasised.
The favourable properties of the resin-matrix ceramics, such as modulus of elasticity similar to dentin, shock-absorbing characteristics and high resilience and fracture resistance, are also covered in this article.
对口腔修复体的高美学期望推动了材料向全陶瓷材料的质量发展，全陶瓷材料能够替代烤瓷熔附金属系统。
本文回顾了涵盖当代全陶瓷材料和系统的文献，重点关注化学成分和材料性能；还为其使用提供了临床建议。
介绍了玻璃基陶瓷和多晶陶瓷，以及最近引入的可加工材料、全氧化锆和树脂基陶瓷。强调了氧化锆的特殊性能，如相变增韧、晶体结构稳定、低温降解以及影响氧化锆老化的因素。
本文还涵盖了树脂基陶瓷的有利性能，如与牙本质相似的弹性模量、减震特性以及高弹性和抗断裂性。
