Crowns and bridges

The most common dental restorations that solve the problem of tooth loss is crown or sleeve. This solves the problem of lack of one or more teeth. Also, crowns can solve the problem of discolored teeth, misplacement or lack of teeth as a result of caries or trauma. They can be made on natural teeth, abraded teeth or implants. They are divided into two basic groups: metal ceramic and metal-free crowns.

Metal ceramic crowns are dental restorations that have been in use for several decades and which slowly go down in history. They are made in a way to inflict various types of ceramics on metal base or construction. In certain situations, the truth very rare, remain No. 1 in the treatment of some types of edentulousness. In addition to its quality, which they undoubtedly have, we have to mention the disadvantages that this compensation send to history.

• According to statistics, about 7% of the population has some type of allergy to metal.
• With metal, it is impossible to achieve superior aesthetics, because it prevents the natural transparency of the tooth, so all metal compensations have their own, specific color.
• Over time, due to gum recession, edge of the crown becomes visible, which is gray, so the aesthetic moment with the gray color around the teeth is very bad.
• In certain cases, there may be some types of electrolysis and staining of tissue, ie. gingiva in metal color, which is very difficult to remove.

Consequently, dentistry had to overcome this problem. Problems are solved by finding metal-free crowns, which currently represent the last word of dentistry.

Metal-free crowns can be made of alumina, zirconia, lithium silicate ceramics, may be modeled by a computer or manually and can be performed individually or in blocks, the point is that they have managed to overcome the problems of metal ceramic crowns. Metal-free crowns are the kind of highly esthetic restorations completely constructed of ceramic. Metal-free crowns mimics the natural characteristics of teeth (light  emission). The crowns excellent fits in the dental arch, especially in situations where it does not make up for all the teeth, but only some of them, and can not be distinguished. The material itself is completely bio-compatible, so there is no reaction of the surrounding tissue. When gum recession, there is no occurrence of gray edge, because the edge is of the same color as the tooth.

You should ask your dentist of confidence what kind of compensation is best for a particular case, ie. which is the best solution to a particular situation. In a conversation with him, explaining all the things you do not understand, the doctor needs to find a final solution to the satisfaction of the patient.
