On the behaviour of zirconia-based dental materials: A review

Zirconia-based dental materials are extensively used in clinical practice due to their tooth-like appearance, biofunctionality, biocompatibility, and affordability. However, premature clinical failures of veneering porcelains raise a concern about their integrity. Extensive studies have been performed over a decade to resolve this issue, but it is challenging to reference all information effectively. A single source identifying the significance of potential parameters on material performance has not previously been available. An evidence-based metanarrative review technique was used to review the characteristic parameters that can affect the overall behaviour of zirconia-based materials. Keywords were chosen to assess manuscripts based on scientific coherence with this paper's research objective. Online keyword searches were carried out on ScienceDirect, PubMed, and SAGE databases for relevant published manuscripts from year 1985-2020.261 out of 3170 identified manuscripts were included. A total of 10 parameters were identified and classified into the material, manufacturing, and geometric aspects. The effect of every parameter was reviewed on the performance of the material. A discrepancy in findings was observed and is attributed to the fact that there is no standard methodology. This review acts as a single source that summarizes various parameters' contribution to zirconia-based dental materials' performance. This review facilitates manufacturing improvements by accounting for every parameter's effect on overall performance.

基于氧化锆的牙科材料因其类牙外观、生物功能性、生物相容性以及价格可承受性而在临床实践中被广泛使用。然而，饰面瓷的过早临床失效引发了对其完整性的担忧。十多年来为解决这一问题进行了大量研究，但有效参考所有信息具有挑战性。此前没有一个单一来源能够确定潜在参数对材料性能的重要性。采用了一种基于证据的元叙事综述技术来综述可能影响基于氧化锆的材料整体性能的特征参数。根据与本文研究目标的科学连贯性选择关键词来评估手稿。在ScienceDirect、PubMed和SAGE数据库中对1985 - 2020年相关已发表手稿进行了在线关键词搜索。在3170份确定的手稿中，有261份被纳入。共确定了10个参数，并将其分类为材料、制造和几何方面。综述了每个参数对材料性能的影响。观察到研究结果存在差异，这归因于没有标准方法这一事实。本综述作为一个单一来源，总结了各种参数对基于氧化锆的牙科材料性能的贡献。本综述通过考虑每个参数对整体性能的影响，促进了制造改进。
