Veneers basically refer to the synthetic resins that are used as curative adhesives in the dentistry. These are preferred in the concerning field due to a number of reasons and some of them are insolubility, ease of manipulation, insensitivity towards dehydration, easy to pocket and aesthetic. If given a look at its composition then one can conclude that it composes of Bis-GMA analog or Bis-GMA monomer plus a filler constituent namely photoinitiator and silica. Flow ability is also possible as dimethacrylates are added to this. Nevertheless, with time many more modifications are being made to make it tough and capable. Use of compound reinstatement with enamel and dentin bonding measures helps in reinstate back the tooth its former physical veracity. Composite veneers are itself soft in nature but where these are placed harden and polymerize to form the solid filling. Be deficient in of diffusion of beam further than 2 to 3 millimeters into the compound makes it fairly difficult for all composite to harden consequently, assignment of wide layers of composite in the tooth makes it to stay yielding. This is very useful in killing the irritation or any harm that has been done to the nerves. Thus, the doctors recommend that one must wait until the composite has fully polymerized. And further, more layers could be added and yes, too much filling must not be done as in future it might lead to chewing sensitivity. These are very different from the porcelain veneers and comprise of basically the inorganic fillers such as silicon dioxide and resin based oligomer matrix. Few other are urethane dimethacrylates or bisphenol A-glycidlmethacrylate. And, yes composition may differ also depending on the fact that either these are engineered using glass ceramics or filler glasses or combinations of resins are used to make a matrix. The main ideology of using filler is to make the veneer look translucent and must have resistance. Obviously when you are talking about developing a matrix, there has to be a coupling agent and in this case silane is used. And, for the initiator external sources are used as in like heat or light. A catalyst package is also there so that the speed could be maintained. An assortment of benefits is related to veneers and among all the main benefit is improved aesthetic in comparison to the previous filling technique. Few other benefits are intensification of the organization of the tooth due to being glued into the tooth, obtainable in wide range of colors hence making it tricky to be noticed, the development of acid engraving of tooth or teeth to enable a tooth micromechanical link enhances most favorable adhesion of tooth re-establishment for this reason avoiding formation of preservation features that might wipe out vigorous tooth. Composite veneers are the one that are placed in a clinical approach and in this case polymerization is achieved by heat which is produced at a certain wavelength and controlled by catalyst. When this approach is being carried out, it would be advisable if shield is put on operator’s eyes and even the one who is holding the light. This technique is very useful for the ones who want to get their gaps filled and want to have partial crowning done.
