Veneers are one of the best advancements in cosmetic dentistry. They are made in the lab from a thin layer of porcelain. They are then cemented directly over a slightly prepped tooth. They are best performed over a healthy, non-chewing surface or front tooth. They can cover stains, close spaces, cover chipped teeth and change the color of the teeth. They are very natural looking, resilient to wear and improve the appearance significantly. They will not discolor. If you are looking for white teeth, porcelain veneers are the ultimate. The dental veneers procedure usually take two office visits.
On the 1st visit, a small amount of tooth is reduced from the front (facial) to compensate for the thickness of the veneer. An impression is then taken of the patients prepped teeth and sent to the dental lab for custom fabrication. You are then fitted with a temporary facing for approximately two weeks.
To cement the completed veneer, the Alaska dentist in Anchorage carefully prepares the tooth with acid gel, which creates small pores on the surface of the tooth. When the new veneer is pressed against the prepared tooth, the pores interlock and create a very strong bond. Because they are porcelain, the possibility of fractures are present but rare. The veneers should last a lifetime with proper care. Ask if there are any guarantees against fracturing.
A silicone precast is created from the set-up, and a proper abutment is chosen. On top of the abutments, primary telescope crowns and galvanically produced secondary parts are constructed along with a gingival mask for the verification of the gingival margin
The tertiary framework was produced with the model casting method. With the cast and finished tertiary structure, the optical verification with the veneers in the precast takes place. A transfer key for the abutments is mandatory as the absence of the rotation lock requires it in the dental veneers procedure.
In the next step of the dental veneers procedure, the abutments are placed and definitively screwed in with the transfer key. Non-rotation locked abutments can only be placed once and have to fit perfectly in the secondary construction in the mouth in other words: on the first try. The primary crowns are bonded to the abutments, and the secondary crowns are placed on top followed by a try-in of the tertiary structure and tension-free cementing. Another impression over the tertiary structure is necessary because we have to produce a new model to finalize the work. The travel prosthesis is integrated and lined with a non-hardening material.
After the model is produced the same tooth shape of the veneers is placed on the tertiary structure unless the patient requests changes. These are the advantages of travel prosthesis: the abutments and primary crowns are placed in the mouth quickly; the patient can leave with her first prosthesis. The patient can test the prosthesis in her daily life: is the speech as it was during the try-in? Is the aesthetic effect to her liking?
The finishing of the veneering from the palatal region and the designing of the inter-dental areas is carried out with crealign. These composites can be used for the characterization of the veneer in the selected dentine and incisal shades.
