Los Angeles, CA (PressExposure) August 14, 2009 -- Dental bridge is one of the many fixed prosthodontic materials, along with dental crowns, veneers, as well as inlay and onlay, that is used to restore missing tooth. Traditionally, materials used to make dental bridges are made from gold and porcelain. Gold, although not as aesthetically pleasing as those with porcelain, is known to last twice as long as porcelain as well as stronger. Porcelain, however, is more aesthetically pleasing than gold, although not as strong as gold. The only similarity that these materials both have is that they can only be applied indirectly.
Other than gold and porcelain, composite resins have been made available for use in dental bridges. So what are composite resins? What are the advantages of using them compared to the use of porcelain and gold to fabricate a dental bridge?
Composite Resins According to the dentist burbank [http://www.alhambradental.com/blog], composite resins are made from Bis-GMA monomers or some Bis-GMA analog, as well as filler material such as silica and in most current applications, a photoinitiator. Composite resins are widely used today as restorative materials for different practices of dentistry, particularly with cosmetic such as dental veneers and crowns. Since they are insoluble, aesthetic, insensitive to dehydration, and inexpensive, composite resins quickly grew in demand, particularly as a material for dental bridges which are also known as resin retained bridges.
Resin retained bridges One advantage that made composite resins in demand in the practice of dentistry, particularly with dental bridges, is they are relatively cheaper than porcelain or gold. They also require little, or no damage, to the surrounding teeth which is usually required for porcelain or gold based dental bridges. Another is that it is well tolerated by patients compared to gold. According to the dentist burbank [http://www.alhambradental.com/blog], the success rate of applying a resin retained bridge is as high as 80% compared to gold and porcelain. This is mainly due to its flexibility to be used in both direct and indirect application, which is beneficial when certain instances make the other method incapable of accomplishing the job. Also, resin retained bridges are said to last for more than 15 years.
Another major advantage of the resin retained bridge over a conventional bridge is that the failure mode is likely to be debonding of the retainer. In conventional bridges the failure mode is likely to be complete fracture of the abutment tooth with difficult to manage sequelae, possibly requiring root canal treatment. According to the dentist burbank [http://www.alhambradental.com/blog], with a resin retained bridge the prosthesis can usually be cleaned off and rebonded in position with minimal inconvenience to the patient.
