What is Prosthodontics?
Prosthodontics’ task is the occlusion restoration after the tooth loss or massive teeth damage using dental bridges, crowns and dentures. A missing tooth causes the movement of adjoining and opposing teeth and major bone level decrease. This situation may result in more teeth loss, lowering the occlusion aesthetic and chewing functions.
What is the prosthetic crown?
The prosthetic crown – a permanent denture covering a damaged tooth crown applied when it’s impossible to restore the tooth with UV-curable composite or if there is a high risk of tooth breakage. The crowns are also being used for broken or highly stained teeth.
What is the prosthetic crown application procedure?
Before the crown application, the tooth needs to be polished. During the same visit, the doctor will prepare a tooth print for a tooth model and the dental-prosthesis maker will prepare a crown accordingly to the doctor’s indications. The crown will be applied to the patient’s oral cavity on the second visit. In case of a serious tissue damage it is recommended to perform the endodontic procedure with post and core treatment first.
What are the types of prosthetic crowns?
In our clinic we offer:
Porcelain crown on steel base
The construction is based on a metal frame covered with porcelain. This type of crown provides a very good aesthetic result and optimal treatment costs. The advantages are:
- good aesthetic
- restoration of lost tooth tissue
- residual tooth structure enforcement
- good tightness
- durability and mechanical strength
- a reasonable price
Porcelain crown on golden base
The construction is based on a golden frame covered with porcelain. This type of crown provides a very good aesthetic result but the cost of the treatment is higher. The advantages are:
- very good aesthetic
- biocompatibility – low allergy risk
- the bacteriostatic properties of gold lower the risk of secondary caries
- the yellow colour of gold provides a better aesthetic result than the steel based crown
- the higher elasticity and malleability of gold provide better mechanical properties of the crown
Porcelain crown on zirconium oxide base (fully ceramic crown)
The core of the crown is made of zirconium oxide which is very sturdy and teeth-white. What’s more, the zirconium oxide is highly biocompatible therefore the risk of allergy doesn’t exist. It’s only flaw is the price. The advantages are:
- perfect aesthetic
- totally biocompatible to the tissues
- tooth-like abrasion
- it doesn’t affect tomography or MRI – no metal in the structure
Acrylic crown – temporary crown
After the tooth polishing, the tooth print is being made and it takes few days for the final crown to be prepared in the laboratory. Therefore the doctor will secure the tooth stub with an acrylic crown providing the patient’s comfort until the proper crown is being applied. Thanks to this only the patient and the doctor are aware of the procedure in progress.
Acrylic crowns are mechanically weak and the aesthetic of them is pretty low, thus they are only being used as a temporary measure during the treatment procedure.
