The intraoral 3Shape scanner gives us the possibility to achieve a digital image of the patient’s teeth, adjust the proper colour and establish the individual occlusal conditions before the prosthetic crown installation. After the crown has been designed the milling machine creates the ceramic crown accordingly to the project. This process reduces the time and increases the precision!
What is the role of dental prosthetics?
The role of dental prosthetics is to reconstruct the initial occlusal conditions after the tooth loss or damage. To this end, bridges, crowns and prostheses are used. Leaving even a single missing tooth without reconstruction causes the neighbor teeth to migrate, the opposing tooth protrudes or a significant reduction in the bone level. Subsequently, this may lead to the loss of more teeth, thus worsening the overall aesthetics and impairing the chewing function.
What is ta 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 during the second visit. In case of 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
What are the advantages of crowns on steel base:
- 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
What are the advantages of crowns on golden base:
- 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.
What are the advantages of crowns on zirconium oxide base:
- 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.
