Several alternatives to full esthetic crowns have been presented. Preparation techniques and factors to be used in patient selection have been discussed for using all-metal esthetic retainers. Problems that arise from the indiscriminate use of full-coverage crowns must not be overlooked. Adjunctive esthetic retainers such as pinledges, three-quarter crowns, and inlays can be used to provide a functional, conservative alternative to full crowns while maintaining maximum esthetics.
已经提出了几种全瓷冠的替代方案。对于使用全金属美学固位体，已经讨论了制备技术和患者选择时要考虑的因素。全冠滥用所产生的问题不容忽视。诸如针状边缘、3/4冠和嵌体等辅助美学固位体可用于在保持最大美学效果的同时，为全冠提供一种功能性、保守性的替代方案。
