Is the process of reduction and coating teeth loss of material due to dental caries, fractures or other reasons or for aesthetic reasons. BRIDGE: Is the intermediate empty filling operation in case of lack of one or several teeth, reducing the volume of the adjacent teeth and drawing thereto. In case of tooth loss for any reason, the neighboring teeth begin to move empty. Following this, gum problems, bone loss associated with spills, malfunctions on the line of chewing and aesthetic problems appear on the teeth. These voids must be restored with implants or bridges.
CROWNS AND BRIDGES TOTALLY DENTAL PORCELAIN :
The reinforced porcelain or zirconium is used as infrastructure instead of metal. As zirconium is a white material infrastructure, it gives very good results close to the natural appearance in aesthetic work.
- As the infrastructure is not metal, a dark drawn does not appear at the gum-crown and a more aesthetic appearance appears.
- When withdrawn gums, integral porcelain retain their aesthetic appearance but the porcelain metal infrastructure make appear a grayish appearance to reflect in their area of union with the tooth.
- The full porcelains do not cause allergic reaction that can appear on certain materials (nickel) contained in the metal infrastructure.
Zirconium oxide is a product of high strength and durability. It combines the highest aesthetic and the highest biocompatibility. Allergic reactions are not known, metal-sensitive people can be rehabilitated without fear. The edges visible and gray metal-ceramic crowns of the past. Les bords visibles et gris des couronnes céramo-métalliques appartiennent au passé.Material:
Zirconia, the new biomaterial allows for white or colored infrastructure, bridges or unit up to 12 items securely. Its excellent biocompatibility eliminates any risk of release of metal ions in the body. His perfect breaking strength, in fact the material of choice for prosthetic reconstruction pillar on natural or implant.
Areas of use Zirconium?
- In restorations of dental crowns for single tooth
- In bridge restorations
- In the crown bridge restorations on implants
Method of preparation of the crown-bridge zirconium
The patient's teeth for which the realization of a crown or bridge is decided zirconium are prepared under anesthesia and measurements are carefully taken and actions are sent to the laboratory for a plaster model.
Temporary crowns are made to the patient for the continuation of patient comfort during laboratory operations. The teeth cut on the resulting plaster model is scanned by the CAD system and the infrastructure zirconium are obtained by stripping from zirconium blocks on computerized machines.
The infrastructure zirconium obtained is sent to the doctor for a test. The doctor tries zirconium infrastructure on the teeth and check its compatibility with the teeth and gums. If there is no problem during the test, the choice of color is done and the infrastructure is returned to the laboratory for fabrication of porcelain superstructure operations. The laboratory affix porcelain on zirconium infrastructure depending on the chosen color and the porcelain produced is sent again to the doctor to be tested.
This phase is called dental trial and at that stage the compatibility of the restoration made with the teeth and gums, morphological structures and relations with the chewing area are checked once again and it is returned to the lab to be polished after the stripping operations and necessary development. The laboratory is polished porcelain following any desired changes by the doctor and the final leveling operations. The finished porcelain is now ready to be inserted in the patient's mouth and to use.
