? It can be said with certainty that all-ceramic teeth enjoy a high honor in the ceramic industry. Others once said: to say the shortcomings of all-ceramic teeth, it is really to find bones in eggs. No matter how good all-ceramic teeth are, all-ceramic teeth also have their shortcomings and indications. So what? What are the indications for all-ceramic teeth? The disadvantage of all-ceramic teeth is that they are more expensive than other porcelain teeth. Many patients, especially women, often have allergic reactions to porcelain-fused-to-metal restorations. This allergic reaction usually manifests as severe inflammation or gingival hyperplasia at the gingival margin of the crown. For this reason, I prefer to choose all-ceramic dental restorations. In addition, most dentists and technicians admit that all-ceramic crowns and bridges can achieve better aesthetic effects in some aspects. However, all-ceramic dental prostheses also have their shortcomings, mainly in the high price, which is difficult for many people to accept. What are the indications for all-ceramic teeth? 1, single crown restoration: In most cases, all-ceramic teeth can be used for single crown restoration, and the restoration effect is better than that of metal ceramic crowns. 2. Multi-unit fixed restorations: short-span restorations can be made with some all-ceramic powder. 3. Single crown with dark color or stripes: In some cases, when porcelain-fused-to-metal restorations cannot be used, all-ceramic teeth can make single crowns with dark abutment because of their good color masking effect. 4. Used for the restoration of anterior teeth with high aesthetic requirements: it is difficult to achieve the ideal effect with metal porcelain teeth when single crown restoration of anterior teeth is carried out. Here, all-ceramic powder and dental resin reinforced cement is the best choice, which can achieve good aesthetic effect.
