In the search for the ultimate esthetic restorative material, many new all-ceramic systems have been introduced to the market. One such system, In-Ceram, is primarily crystalline in nature, whereas all other forms of ceramics used in dentistry consist primarily of a glass matrix with a crystalline phase as a filler. In-Cream can be used to make all-ceramic crowns and fixed partial denture frameworks. Three forms of In-Ceram, based on alumina, spinal (a mixture of alumina and magnesia), or zirconia, make it possible to fabricate frameworks of various translucencies by using different processing techniques. This article discusses clinical indications and contraindications for the use of In-Ceram Alumina and In-Ceram Spinell all-ceramic restorations. Particular attention is given to cement considerations using several clinical examples.
在寻找终极美学修复材料的过程中，许多新型全瓷系统已投放市场。其中一种系统，即In-Ceram，本质上主要是晶体，而牙科中使用的所有其他陶瓷形式主要由玻璃基质和作为填充剂的晶相组成。In-Cream可用于制作全瓷冠和固定局部义齿支架。基于氧化铝、尖晶石（氧化铝和氧化镁的混合物）或氧化锆的三种In-Ceram形式，通过使用不同的加工技术，可以制造出具有不同透明度的支架。本文讨论了In-Ceram氧化铝和In-Ceram尖晶石全瓷修复体的临床适应证和禁忌证。通过几个临床实例，特别关注了粘结方面的考虑因素。
