Is the specialty which mission is teeth reconstruction.
Prosthetic reconstructions can be:
- fixed prosthesis ;
- crowns or dental bridges;
- adhesive prosthesis (on metal or fibreglass);
- prosthesis on dental implants;
- dental prosthesis ;
- dental veneers ;
- dental incrustations.
Crowns and dental bridges can be made of:
- porcelain on dental support (chrome – cobalt or palatinate gold) ;
- porcelain on zirconium oxide;
- full ceramics.
When the evolution of the dental caries (link to caries therapy) or a fracture destroyed a large part of the tooth, it cannot be restored by an obturation (fill). There is little and thin dental tissue left and cannot support the pressures during mastication. This is why is necessary to protect the remained walls and to cover them with a dental crown.
Also, the teeth can be restored by means of the crowns if the teeth display shape modifications, enamel forming deficiencies or major colouring which cannot be remove by professional whitening or by ceramic veneers.
If the tooth cannot be saved and must be extracted, it can be replaced by a dental bridge or a dental implant. The dental bridge is supported by two or more column teeth, therefore replacing one or two missing teeth.
Dental prosthesis can be: partial or total, acrylic or skeletal and are designed for the persons who lost a great number of teeth.
Total prosthesis replace all the teeth and the partial ones are anchored on the remained teeth. Even if the idea of “prosthesis” scared most of the patients, it integrates very good in the mouth cavity and can be comfortably used many years.
Is a device replacing missing teeth, being anchored on the remained teeth by various fixing systems and it can be removed by the patient. Although in a first stage the psychological impact on the bearer can be big, once accepted and integrated in the mouth cavity the prosthesis ensures a good mastication and phonation, as well as a satisfying aesthetics.
The advantages of the prosthesis are given by their fast fabrication, by the lower cost price. The disadvantage is given by the fact that they are movable (they must be removed from the mouth cavity and sanitised).
Dental incrustations are some “obturations” / “fills” made in the dental technique laboratory, following an impression taken by the doctor.
– recommended fi the tooth lost most part of its structure, nevertheless, for restoration, a dental crown is not necessary.
– a more resistant and aesthetic solution.
