Dental Veneer or veneer is a very thin, translucent ceramic shell for the teeth, which is applied with special adhesive on the tooth surface – especially of anterior teeth -. The adhesive shell is made of ceramic. Apart from rare allergies to the mounting material, the use of ceramic veneers is usually not a health hazard, because the ceramic material has a very high biocompatibility. There are problems only with very solid fluoridated enamel. In addition, the necessary occlusal the risk of chronic pulpitis (inflammation of the teeth), which must inform the doctor (decision of the OLG Hamm of 30 May 2011). Veneers can correct minor malocclusions, gaps in the teeth, unsatisfactory tooth colors and local discoloration. Veneers give the visible surfaces of the teeth an optimized appearance, and tooth color is also individually corrected in this procedure. As a rule, old plastic fillings or corner structures are removed when they are used.
Present clinical long-term studies show that only two percent of ceramic veneers are lost within six years. This positive result has led to the recognition of the procedure by the German Society of Dental, Oral and Maxillofacial Surgery (DGZMK).
Ceramic is light-transmitting and tooth-colored and thus enables a very aesthetic tooth pattern. In addition, it is chemically inert, that is, it does not dissolve in the mouth and is therefore biologically very compatible.
Procedure of Dental Veneers
A non-prep veneer: in contrast to conventional veneers, it is much thinner. Their average thickness is 0.3 mm.A thin layer (0.3-1.0 mm) of the enamel is removed. This preparation is based on the anatomical conditions with the aim to achieve an optimal cosmetic and durable result. There is an impression. The provisional supply takes place with plastic veneer. The dental technician makes the veneer on the model and gives it to the dentist for insertion. After a try-in by the dentist, the tooth is cleaned and ideally drained with the help of rubber dam. The enamel is etched, possibly exposed dentin is treated with a so-called Dentinadhäsiv. The ceramic veneer is treated with special ceramic etching gel and silanized to ensure good adhesion of the composite plastic adhesive. The bonding of the ceramic with the tooth is quite complex and usually takes about 30 minutes per tooth with all preparatory measures.
By applying new techniques, it is possible to make veneers in the material thickness of contact lenses (about 0.2 mm). They offer the advantage that they can be applied directly to the tooth hard substance, that is without prior grinding of the tooth. These non-prep or non-invasive veneers also offer the possibility of extended indications. In contrast to conventional veneers, they can also be adhesively attached to earlier plastic fillings, ceramic crowns or bridges.
Patented developments allow today by so-called insertion aids an enormous time savings, since all veneers of a patient can be incorporated simultaneously. This procedure saves about 80-90% of the time required for conventional veneers and significantly reduces the cost factor.
Depending on the quality and effort that must be used for veneers (ceramic or hybrid plastic), a veneer costs between € 300 and € 1,500.
Whether and to what extent then a privately insured patient to reimburse the fee and laboratory costs for the preparation and use of such preparations from his health insurance, sometimes provides for dispute. If the veneer is not only used for aesthetic reasons, but is to be regarded as a justifiable treatment, the district court of Frankfurt am Main arrives in a judgment from 2004 to a refund obligation of private health insurance.
History of Dental Veneers
First veneers existed in the 1930s, at that time still as plastic veneers. The then child star Shirley Temple had supposedly too short milk teeth. On the set her dentist had to be present with several veneers for her. The gluing technique was not known at the time. These early veneers were much thicker than today. They had to be painstakingly glued with denture paste and only lasted a few hours on the tooth surfaces. It was Californian dentist Charles L. Pincus, founder and first president of the American Academy of Aesthetic Dentistry, who stated in a 1937 lecture to the California State Dental Association (now in Sacramento): “A winning smile that is an even series of natural, shimmering white teeth is an essential factor to achieve that hard-to-describe, all-defining characteristic called personality. “Pincus, who treated stars such as Marilyn Monroe and James Dean and 1986 at the age of 82 Died years ago, is considered together with Ronald Goldstein as the “father of veneers”. For his merits he was u. a. recorded in the Hall of Fame of the University of Southern California.
Veneers are manufactured by dental technicians or in state-of-the-art CAD / CAM centers. There are dental technicians who specialize in the manufacture of ceramic veneers for cosmetic restorations.
