Non-Prep or non-invasive veneers
Description of non-prep veneers
Non-Prep or non-invasive means a process without preparation and without the tooth attack. As the name suggests, the teeth are not prepared at this Veneerart. That is, to make the veneers, no tooth structure is sacrificed, and the teeth do not have to be ground. Only in rare cases, a minimum removal is required.
Especially in the area of the anterior esthetics allow non-prep veneers aesthetic corrections quickly and painlessly. In particular for patients whose tooth structure is intact, but their own standards is not enough, the non-prep veneers offer an appropriate solution.
The contact lens large non-prep veneers can be found in very different situations apply:
- Closure of unattractive gaps in the anterior region
- to achieve modeling of the teeth to a new course of the dental arches
- Permanent whitening of teeth
- Extension or dissemination of teeth
- Aesthetic optimization of the front teeth or the entire row of teeth
The care of the teeth with non-prep veneers
If the Zahnstellung- and situation permits, and with minimal effort of the dental arch are to be formed, and the veneers are made on a laboratory-produced model. However, special ceramics and extreme dexterity of the technician is required for this procedure. The wafer-thin ceramic shells are usually thin around 0.3 millimeters. The ceramic used to have a lifelike fluorescence, and thus the structure and refraction of natural teeth easily simulate. For the non-prep veneers are best suited smaller teeth or those that or gaps therebetween.
The veneer in the picture above was prepared by our specialized veneers dental laboratory in Hanover and has a thickness of only 0.2 millimeters in the middle pane. In order to produce such thin veneers, both highly trained dental technicians and specially developed for this purpose ceramics are necessary.
A number of ceramic manufacturers has for some time developed special ceramics, with which one can produce the wafer-thin ceramic shells. For Veneerherstellung spot speaks:
- The proximity to the dental laboratory
- The short processing time
- The substitution between dentist and technician
- The possibility that the patient can go to the lab itself to evaluate on- Zahnfarbe- and shape by the dental technician
Advantages of non-prep veneers
account for labor-intensive and sometimes unpleasant steps such as grinding of the teeth or anesthetic injections.
A short deadline for the impression is sufficient usually. Therefore, this method is well suited for anxious patients.
Since teeth are not ground down, the non-prep veneers can be easily removed from the teeth again.
Because no preparation is done, these veneers can also in children (eg after tooth trauma, tooth fracture) are used.
Provisional veneers are not necessary because no tooth is ground.
Disadvantages of non-prep veneers
Only a few dental laboratories master this technique and have the necessary experience and the special ceramic materials for this process.
For a good result, it is very often necessary, a plurality of teeth (usually 4, 8 or 10 teeth per jaw) to supply in order to achieve the desired appearance.
Very dark teeth can shine through. The low heavily stained teeth may be insufficiently covered.
Higher Labor costs for the production. The production technique is expensive and the bonding process takes longer.
