Esthetic Solutions With Layered Zirconia Prostheses: A Case Report

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.

The data were pooled for analysis, statistical significance was set to p-value ˃ 0.05. Results: There was a significant differences in the parallel interpupillary line and coincided of dental midlines alone and with facial midlines in the aesthetic and non-aesthetic choices, also between the symmetry of maxillary central and lateralicisors, and canines with their axial inclinations choices (p< 0.05). Some group of questions showed significant differences among female and male subjects while, the male subjects Some questions were near to the statistical significant differences, while others showed no significace between males and females choices.
