Ceramics are very important in the science of dental biomaterials. Among all dental ceramics, zirconia is in evidence as a dental biomaterial and it is the material of choice in contemporary restorative dentistry. Zirconia has been applied as structural material for dental bridges, crowns, inserts, and implants, mostly because of its biocompatibility, high fracture toughness, and radiopacity. However, the clinical success of restorative dentistry has to consider the adhesion to different substrates, which has offered a great challenge to dental zirconia research and development. This study characterizes zirconia as a dental biomaterial, presenting the current consensus and challenges to its dental applications.
陶瓷在牙科生物材料科学中非常重要。在所有牙科陶瓷中，氧化锆作为一种牙科生物材料备受关注，并且是当代修复牙科的首选材料。氧化锆已被用作牙桥、牙冠、嵌体和植入物的结构材料，主要是因为它具有生物相容性、高断裂韧性和射线不透性。然而，修复牙科的临床成功必须考虑与不同基底的粘附性，这给牙科氧化锆的研发带来了巨大挑战。本研究将氧化锆表征为一种牙科生物材料，介绍了其牙科应用的当前共识和挑战。
