What are the advantages of ceramic crowns?
The task of modern dentists and dental technicians is not only to restore the functions of the lost tooth but to make it look nice and natural. It is not so easy but this very task makes the whole branch of dentistry develop.
Modern prostheses (crowns) requirements:
1. Prostheses must be biologically compatible. Nowadays this factor is very important. Completely ceramic prostheses are compatible. They can be used if the patient wants no metal elements in his prosthesis.
2. Prostheses must be aesthetic, look nice. A good prosthesis must look exactly like a normal tooth. To make a prosthesis like that a good dentist will have to repeat all steps of the nature when it created teeth. Using metal frameworks makes the task even more difficult as they live not enough space for proper coloring. It will be impossible to make the color of the tooth look natural. Healthy teeth are not simply white. Their color is deep. You can secure this deepness of color only if you have enough space.
In case the dentist uses pressed ceramics instead of metal to restore teeth
it will be much easier to make the implant look like a normal tooth. Caps made of pressed ceramics have the natural color of dental tissues. It is possible to preserve the anatomic form of the tooth using metal-ceramic constructions. But in this case the adjacent teeth will be more damaged as the dentist will have to grind them. To crown it all, we can see that ceramic constructions look better and need less grinding of the adjacent teeth. Moreover, healthy teeth are semitransparent. Metal used in the dental construction makes the tooth look non-transparent.
3. Your gums should also look natural. If the edge of the gum exposes, everybody will see the crown. Many people have seen darkened gums or a metal edge around the tooth. It does not look attractive, does it? Metalless constructions do not have these disadvantages as they do not contain metal. Metalless constructions will save you from gum traumas, periodontitis, and gingivitis.
4. Metalless construction are easy (and quick) to make. There is no need to cast a metal framework. This way you can avoid mistakes caused by imperfections of equipment. Even though the dental engineering is rapidly developing mistakes also happen.
5. Ceramic prostheses have the same thermal dilatation as healthy teeth. You will feel no discomfort eating or drinking something cold or hot. Ceramic crowns will serve you longer. What is more important, you are protected from splits.
6. Constructions of metal can cause allergies and idiosyncrasy while ceramics is safer.
7. Ceramic prostheses are light. Weight makes no big difference if you have to restore only one tooth. But in cases when restoration of some teeth is needed metal crowns may simply turn out to be too heavy.
8. There is another advantage of ceramic restoration. Adhesive fixation is possible. It turns the artificial tooth and the root into a single whole. Restorations of this type are fixed with the help of special cement.
9. Only low-temperature ceramics is used in dentistry. It secures natural erasibility of the artificial tooth.
