Premium Porcelain Veneers for Teeth
Veneers are generally considered to be made of porcelain. There are two types of porcelain or ceramic used:
Type 1 – Feldspathic porcelain is highly aesthetic and if the bite allows – it is the most desirable. Patients who are Bruxers (Heavy tooth grinders) should avoid Feldspathic porcelain veneers.
The downside of feldspathic porcelain veneers is because they are so thin, as you age, the darkening tooth underneath may shine through. In some cases crowns may be required at an older age to mask out the darkened teeth.
Type 2 – Zirconia/Porcelain Veneers are now available which are the strongest. The substructural frame and biting edge is made of zirconia and the front or facing is made of porcelain these are ideal for Bruxism patients. However, they are not as translucent as Feldspathic porcelain veneers but better at masking out underlying negative dark tooth colour.
There are also two ways to make a Veneer:
Process 1 – To fabricate a Contemporary Veneer (Zirconia/Porcelain or Feldspathic Porcelain) a dentist drills a thin portion of the tooth, for example 6/10ths of a millimeter. Hence, the ceramic will then be made 6/10ths of a millimeter thick for bonding onto the tooth.
Process 2 – Alternatively a ‘Preparation-Free Veneer’ can be fabricated to fit the existing tooth. That is, no drilling is performed. This type of veneer is also known as a ‘Prep-less Veneer’ or ‘No Prep Veneer’. This can only be made with Feldspathic porcelain because it is highly translucent in thin sections and will blend inconspicuously into the external shapes of the tooth.
A Contemporary Veneer is uniform in thickness and will have uniform colour, superior strength and with less finish lines.
A Prepless Veneer has the advantage that no tooth structure has been drilled. However, if the finish lines of the Prepless veneer crisscross the tooth they will be in a visible region which could result in unaesthetic stain lines. If the Prepless veneer is not uniform in thickness (due to your natural tooth structure), there is potential for it to crack and break with time.
All types of Dental Veneers are bonded onto enamel with resin cement – This bond is extremely retentive. However, if there is no enamel present then the next layer of tooth that is available for bonding is called dentine. The bond of a porcelain veneer to dentine is poor and therefore a full Crown would be recommended.
