摘要

目的对颈缘厚度和形状对后置单片氧化锆冠强度的影响进行文献综述。材料与方法检索2014 - 2020年发表的评价不同类型颈缘单片氧化锆冠抗骨折性的研究，检索关键词为:“单片氧化锆”、“半透明”、“无肩”、“缘制备设计”。结果研究分析表明，牙缘的整体设计对冠的强度有显著影响。带有刀口边缘的单片氧化锆冠显示出比人类最大咀嚼力更高的断裂负荷。结论建议采用后置单片氧化锆冠垂直制备是安全的。由于新型的半透明单片氧化锆冠是最近才出现的，需要进一步的研究来指导选择合适的最小刀口厚度以满足临床使用指南。

Influence of the Type and Thickness of Cervical Margins on the Strength of Posterior Monolithic Zirconia Crowns: A Review

Objective The aim of this research is to review the literature for the influence of the thickness and shape of cervical margins on the strength of posterior monolithic zirconia crowns. Materials and Methods Studies to assess the fracture resistance of monolithic zirconia crowns with different types of cervical margins, published from 2014 to 2020, were searched using the electronic database PubMed and Google Scholar using the following keywords: “monolithic zirconia,” “translucent,” “shoulderless,” and “margin preparation design.” Results Analysis of studies has shown that overall the design of the margin would have a significant effect on the strength of these crowns. Monolithic zirconia crowns with a knife-edge margin have shown a breaking load higher than the maximum chewing force of humans. Conclusion It would be safe to suggest the utilization of posterior monolithic zirconia crowns with vertical preparation. As the new translucent monolithic zirconia crowns are recent, further studies would be needed to guide the selection of the appropriate minimum thickness of the knife-edge margin to meet the clinical guidelines for their use.

期刊介绍： European Journal of General Dentistry (EJGD) is one of the leading open-access international dental journal within the field of Dentistry. The aim of EJGD is publishing novel and high-quality research papers, as well as to influence the practice of dentistry at clinician, research, industry and policy-maker level on an international basis. EJGD publishes articles on all disciplines of dentistry including the cariology, orthodontics, oral surgery, preventive dentistry, periodontology, endodontology, operative dentistry, fixed and removable prosthodontics, dental biomaterials science, long-term clinical trials including epidemiology and oral health, technology transfer of new scientific instrumentation or procedures, as well as clinically relevant oral biology and translational research.Moreover, EJGD also publish the scientific researches evaluating the use of new biomaterials, new drugs and new methods for treatment of patients with different kinds of oral and maxillofacial diseases or defects, the diagnosis of oral and maxillofacial diseases with new methods, etc. Moreover, researches on the quality of life, psychological interventions, improving disease treatment outcomes, the prevention, diagnosis and management of cancer therapeutic complications, rehabilitation, palliative and end of life care, and support teamwork for cancer care and oral health care for old patients are also welcome. EJGD publishes research articles, case reports, reviews and comparison studies evaluating materials and methods in the all fields of related to dentistry.
