后牙全锆冠龈边缘预备形式的研究进展

doi:10.7518/gjkq.2023067

摘要/Abstract

摘要：

氧化锆是近年来应用最为广泛的陶瓷材料，由第2代氧化锆制作的全锆冠具有美观、强度高的优势，即使在厚度仅有0.5 mm的情况下，也可承担后牙的咀嚼压力，在后牙全冠修复中广泛应用。后牙全锆冠的龈边缘预备形式多样，包括刃状边缘、凹槽边缘、肩台边缘等。后牙全锆冠由于机械强度较高，龈边缘预备形式与玻璃基全瓷冠有所区别，但仍缺乏统一标准。本文拟对后牙全锆冠的龈边缘预备形式进行归纳总结，探讨不同龈边缘预备形式牙冠的应力分布、机械性能、边缘适合性以及对基牙和牙周组织的影响，为后牙全锆冠龈边缘牙体预备提供临床操作参考。

Abstract:

Zirconia is the most widely used high-strength ceramic material in recent years. Monolithic crowns made from second-generation zirconia have the advantage of being aesthetic and solid enough to withstand the masticatory pressure of posterior teeth even at a thickness of 0.5 mm. These crowns are therefore widely used in posterior full crown restoration. The margin of the crowns can be prepared using knife edge, chamfer edge, and shoulder edge. The margin preparation differs from that of glass-ceramic crowns due to the high mechanical properties of monolithic zirconia crowns, but a standard preparation procedure is not yet available. This review aims to summarize the margin preparation forms for posterior monolithic zirconia crowns and discuss the stress distribution, mechanical properties, marginal adaptation and effects on the abutment and periodontal tissues of different margin preparation forms. Results provide a clinical practice re-ference for the margin preparation of posterior monolithic zirconia crowns.

Key words: monolithic zirconia crown, margin, round shoulder, chamfer edge
