Abstract：
To meet the challenges of rehabilitating anterior teeth and achieving natural-looking restorations, it is essential to address issues such as improper shape, size, irregular gingival contour, and unaesthetic shades. The increasing demand for aesthetically pleasing and metal-free solutions has popularized materials like dental zirconia, offering optimal aesthetics and desirable mechanical properties. Within this context, a case report highlights clinical experiences with layered zirconia fixed dental prostheses designed specifically for anterior teeth. The report focuses on the prosthetic rehabilitation of both endodontically treated and vital abutments, exploring the influence of zirconia composition, design, layering technique, shade selection, occlusion, and the unique clinical challenges associated with each condition. The selection of zirconia composition, framework design, and shade in layered zirconia prostheses is intricately tied to the characteristics of the abutments. This interconnectedness underscores the importance of a thoughtful and customized approach to address the specific requirements of each clinical scenario.
摘要：
为了应对修复前牙和实现自然修复的挑战，解决形状不当等问题至关重要，尺寸,不规则的牙龈轮廓，和不美观的色调。对美观和无金属的解决方案的需求不断增加，已经普及了牙科氧化锆等材料，提供最佳的美学和理想的机械性能。在此背景下,一个病例报告强调了专门为前牙设计的层状氧化锆固定假牙的临床经验。该报告着重于牙髓治疗和重要基牙的假肢康复，探索氧化锆成分的影响，设计,分层技术，阴影选择,遮挡,以及与每种情况相关的独特临床挑战。氧化锆成分的选择，框架设计，层状氧化锆假体中的阴影与基台的特性密切相关。这种相互联系强调了深思熟虑和定制方法的重要性，以满足每个临床场景的特定要求。
