ABSTRACT

Tooth discolouration and the existence of metallic substrates increase the difficulty of restoration to reproduce natural and aesthetic appearance. The commonly used veneered zirconia restorations have a high risk of porcelain chipping, and the monolithic zirconia restorations cannot always achieve satisfying aesthetics. The newly developed self-glazed monolithic zirconia restorations digitally manufactured by additive technique have colour- and translucency-gradient characteristics. They could mask the different coloured substrates and achieve a natural look simultaneously. This clinical report describes the prosthodontic treatments of two patients with different coloured substrates in the anterior region. Both functional and aesthetic outcomes are satisfactory after 1–3 years of follow-up.

摘要

牙齿变色和金属基材的存在增加了修复的难度，以重现自然和美观的外观。常用的贴面氧化锆修复体有很高的碎瓷风险，整体氧化锆修复体不能总是达到令人满意的美学效果。新开发的自上釉整体氧化锆修复体通过增材技术数字化制造，具有颜色和半透明渐变特性。它们可以掩盖不同颜色的基材并同时获得自然的外观。本临床报告描述了前牙区域具有不同颜色基底的两名患者的修复治疗。经过 1-3 年的随访，功能和美学效果均令人满意。
