The techniques and materials available to dentists involved in smile makeovers are constantly improving and great advances have been made in recent years especially when it comes to the use of veneers in a smile makeover.
Veneers are thin facings which are bonded to the teeth to enhance their appearance.
In an ideal world, natural teeth are of a satisfactory shape and shade or colour, and in a position in the mouth which is ideal.
In life, however, this ideal situation is not always present.
Teeth can be discoloured or stained, twisted or rotated, crowded or spaced in combination such that the aesthetic appearance of the smile in unsatisfactory and in need of improvement. Veneers can be used to lighten, brighten or straighten teeth where appropriate and are used on the upper and lower arched on incisor, canine and premolar teeth. Depending on the occlusion/bite, veneers can also be used on the molar teeth.
Veneers can be used with careful planning to correct any or all of the above problems in combination.
Following full case discussion with the patient and planning, together with x rays where appropriate to determine the health of the supporting tooth roots, impressions are taken in order that a diagnostic wax up can be provided. This diagnostic set up is then transferred to the mouth in a temporary material to allow patient visualisation before any treatment is commenced. This is an important stage in the process.
Following approval of this diagnostic set up, the teeth are prepared for final veneers.
It is always the intention to ensure that the preparation of natural tooth tissue is as minimal as possible to preserve the natural tooth structure. In cases of tooth rotation or malpositioned teeth, however, this preparation may require to be a little more invasive. In extreme cases, it may be prudent to consider pre ceramic orthodontic treatment to move the teeth into a more favourable, less invasive position for veneers treatment. In addition, depending upon the case requirements and the smile design required, pre operative crown lengthening can also ensure that the height the gum line is perfect to compliment the perfect smile.
Following the final veneer preparation under magnification, accurate impressions are taken and transferred to the laboratory where the final veneers are fabricated ready for transfer to the mouth. In the intervening period, temporary veneers are generally placed using the transfer technique from the diagnostic wax up described above.
After construction of the veneers, the temporary veneers are removed and the veneer preparations polished before the final veneers are trial fitted for patient approval before being cemented into place carefully.
Veneers can be made from a number of materials depending upon the specific case requirements. These materials include porcelain and composite.
Following completion of veneer treatment, it is imperative to ensure regular attendance to care not only for the veneers but also for the remaining teeth in the mouth to ensure the result lasts as intended. Veneer treatment generally, but not always, requires the use of local anaesthetic for the preparation and fit stages.
