Services offered » Porcelain crown

Porcelain crown is an esthetic prosthesis, restoring dental tissue lost as a result of caries, traumas and other factors.  Such reconstruction method is recommended for patients after endodontic treatment (root canal therapy) to reinforce premolars and molars, patients who have lost too much dental tissue which requires reconstruction, as well as those who have had prostheses in the form of crowns previously, and now should have them replaced with new ones to maintain tightness.

Porcelain crowns are produced in the dental laboratory according to the order of an attending dentist.  It can be made on metal cast support (fabricated even of dental grade gold), onto which porcelain in the color matching that of the patient’s teeth is fired, or it can be all-ceramic – with no metal used.  Another type of crowns is mate of zirconium oxide with zirconium lava components. The particular types of crowns differ in the material used (metal-containing or without metal), as well as color – crowns made of zirconium oxide are much brighter and look more natural than porcelain ones.

In all the cases where the patient has a few adjoining teeth missing, a prosthetic construction referred to as a bridge can be used.  The bridge connects two “banks” (the existing teeth), between which the teeth which have been lost permanently can be reconstructed. The teeth designed to constitute abutments for bridges are subjected to preparation procedures and covered with porcelain crowns.

The technique of porcelain crown production is very precise and employs computer scanning. After obtaining a precise impression form, a gypsum model is prepared by casting in the laboratory, which is then assessed by a special computer program with respect to the site and shape of the crown.   The process allows perfect reconstruction of lost dental tissue.

The prosthetic stage consists of two parts. First the abutment tooth is prepared, tapered under anesthesia, an impression is taken and the tooth covered with temporary protective material to enable the patient to function normally.  During the next visit (usually a week later), so-called structural fitting is accomplished. After another week, following a meticulous control, the process of crown placement (porcelain or zircon one) can be regarded as completed.

All reconstruction procedures are performed under local anesthesia and are practically painless.
