Veneers – Ceramic Veneers for the Visible Part of the Denture


In dentistry, veneers are thin layers of restorative materials, such as ceramic. They are bonded to the cutter or eye teeth that may have been fractured or discolored. Veneers may consist of composites, synthetic materials, and ceramic. The dentist differentiates between the processing methods of veneers made up of composites, on the one hand, and those consisting of ceramic or synthetic material. For veneers made up of ceramic and synthetics are fabricated in the dental laboratory and later simply bonded to the tooth by the dentist in the dental practice. A veneer made up of composites, however, is manufactured during the session at the dentist’s office and will be placed to the tooth immediately afterwards. As a rule, dentists tend to prefer ceramic veneers as they can be better adapted to the color of the adjacent teeth and feature an excellent biocompatibility.
What Are the Conditions for the Use of Veneers?Veneers are a good choice for people who want to improve the esthetic of their denture. Today, the application of the thin layers of ceramic allows for:

Covering up of discolored teeth, alternatively to bleaching methods
Correcting poorly aligned or differently sized teeth
Closing of existing tooth gaps
Covering up of stained teeth
Making old, esthetically questionable amalgam fillings invisible
Replacing fractured margins on existing teeth worth preserving

Using veneers makes particular sense when the existing teeth are no longer corresponding with the esthetic demands of the owner. In cases where bleaching has not yielded much results, veneers might also be a good choice for those looking for a healthy smile. The dentist is also likely to recommend veneers as and alternative to crowns. Veneers are also used to correct poorly adjusted teeth or easily noticeable tooth gaps. Because of its thin layer of dental restorative material, and unlike crowns, veneers do not cover the entire tooth but only the part of tooth concerned.

How do dentists bond a veneer to the tooth?To allow veneers to be properly fixed to the teeth at all, the dentist would have to remove abrasively a thin layer of the existing teeth concerned. Since the layer to be grinded away does not exceed 0.8 millimeters, not much dental substance will be lost by this method. Once the dentist has removed this layer, he or she takes an impression of the remaining tooth, so as to provide the dental laboratory with the exact specifications of the future veneer. Until the dental lab will be done, interim synthetic veneers are placed upon the grinded tooth.

Similar to dental reconstructions after fractures, veneers take advantage of the latest in adhesive technologies. Through this, the fixing procedure of the veneer yields extraordinary results. The actual treatment takes about 45 minutes. Surveys show that allergic reactions due to the introduction of these foreign materials are extremely rare. If the job of the dental technician is well done, veneers are very enduring and easily hit the 15 years mark or more.

Composite Inlays – An Esthetic Alternative to Metallic Restorations

Composites, also called synthetic materials, are advanced dental filling materials, which offer esthetically and lastingly satisfying ways of filling dental cavities. These composites consist of tiny ceramic particles, which are bound by the synthetic part of the material, so as to allow for a plastically shapeable mass, similar to plasticine, which enables easy modeling. After placing, these composites start a hardening process that is rendered possible by their exposure to ultraviolet light. In order to make composites processable, the dentist needs to cauterize the dentine and the dental enamel. The cauterization process disposes of the smooth surface of the tooth and helps the composite filling to adhere enduringly to the dentine. This is because of the development of innumerous, small and microscopic pores. They are needed for the composite inlay to adhere to the dentine or dental enamel. The pores ensure the anchoring of the inlay with the entire contact surface and facilitate the concentration on the dental cavity alone.
As soon as the dentist has cauterized the dental material as therefore prepared and conditioned the tooth for the treatment, small and manageable portions of the composite filling can be placed into dental cavity. Each of the portions will be hardened before a new portion is inserted. As a result, this method requires the insertion of the composite material in the cavity to be done layer by layer, until the cavity is filled. Since composite materials shrink during the hardening process, the dentist has to work very diligent and with great care, because only this would close the cavity and have some of the composite left for the finishing part. Since this excess filling material is not on a level with the chewing surface, but a bit higher (or lower, respectively), the grinding-in process can start as soon as the material has completely hardened. This is no easy task as the composite closely resembles the remaining tooth in color and surface structure. It requires therefore great skills, a good eye, and patience on the dentist’s side to see where the composite ends and the dental substance begins. Every patient is well advised to choose a dentist who is an acknowledged expert on the case and has sufficient experience in the field.

Porcelain Crowns and Full Ceramic Crowns – Just Like Own Teeth

In the past, dentists recommended platinum or gold to fill dental cavities or tooth spaces. But today, they would rather prefer to use porcelain instead. Porcelain crowns cannot be distinguished from own teeth, do not fracture, and cause no allergic reactions. Porcelain crowns consist of zirconium oxide, a material closely resembling own teeth.
As a rule, dental crowns are required in cases where the decay of dental substance is in such an advanced stage (through caries or dissolution) that the dentist is forced to forego placing inlays or fillings. The dentist's recommendation as to the placing of either a porcelain crown or a partial crown largely depends of the degree of destruction of the dental substance.

For their restorative dental treatments, dentists particularly rely on synthetic crowns, crowns made of metal compounds, and dental crowns consisting of metal ceramic. Ceramic crowns have not been used to date as their lack of breaking strength may lead to early damage of the material. Recent scientific research has led to the application of zirconium oxide as an alternative to ceramic materials. Through the introduction of this effective material, porcelain crowns and full ceramic crowns offer even better longevity than the so far used gold inlays and crowns.

Other advantages of porcelain crowns and full ceramic crowns are their constituent elements, namely porcelain, which do not elicit hypersensitivities, and their perfect match as to the color of the surrounding dental substance. For that reason, dentists recommend porcelain crowns and full ceramic crowns for front teeth and back molars. Compounds consisting of porcelain and zirconium oxide are as well resistant to the masticatory pressure as those containing metal elements.

If the dentist is a master of his trade, a porcelain crown or full ceramic crown won’t be inferior to own teeth in terms of color, light transmission, the required strengths and firmness, and the different individual sensations prevalent in the oral cavity. It should be noted, that porcelain compounds consisting of zirconium oxide features basic characteristics dissimilar to restorative material made of metal compounds. The material is considerably lighter and transmits the alternating temperatures caused by air, food, and drinks to the dental nerves, evoking real-live sensations.

Porcelain crowns and full ceramic crowns require more elaborative work on the dental technician’s part than would be the case with metal crowns. This is because of the dental lab’s necessity to mill, burn, and compression-mould the single layers of zirconium oxide for the porcelain compounds. Zirconium oxide is available in different shades of white. The eventual color of the restorative material is selected by both patient and dentist. Porcelain crowns and full ceramic crowns may easily reach longevities of 30 or more years, provided the patient has observed the necessities of dental hygiene.
