Resin Retained Bridge Over Conventional Dental Bridges

The use of dental bridges, according to cosmetic dentistry los angeles centers, is one of the many practices considered as a branch of cosmetic dentistry. It is part of the many methods of dental restorations that are used to replace a missing tooth by joining permanently to adjacent teeth or dental implants. There are different types of bridges, depending on how they are fabricated and the way they anchor to the adjacent teeth. One popular type of dental bridge is the use of composite resins. This practice is called resin retained bridges.

Resin Retained Bridge

Like any other dental bridges, resin retained bridges are used to replace missing tooth, but heavily rely for their retention on a composite resin cement. One good advantage of using a resin retained dental bridge is its cost, which is relatively cheaper. The resin retained bridge is a good treatment option for those with a lot of missing teeth as it is relatively cheap when compared to alternatives such as dental implants, requires little or no damage to the surrounding teeth during preparation for placement, and it is well tolerated by patients.

Success rate: Typical success rates are quoted as high as 80% after 15 years in the anterior maxilla. However, specialists from cosmetic dentistry los angeles have stated that far lower success rates are seen in the posterior mandible and thus, case selection is important. As with any dentistry, good oral hygiene is paramount for success.

Advantage over Conventional Dental Bridges

One major advantage of the resin retained bridge over a conventional bridge is its failure mode which 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. With a resin retained bridge, the prosthesis can usually be cleaned off and rebonded in position with minimal inconvenience to the patient.

Design of Resin Retained Bridge

The wing or retainer must be rigid and is usually fabricated from a metal alloy and the inner surface must fit closely to the abutment tooth. The intaglio is treated in some way to enhance the micromechanical adhesion between the prosthesis and the composite resin cement. In the past,porcelain fused to metal restoration.
various methods have been used, ranging from metal-weave patterns to tin plating. The modern resin retained bridge retaining wing is usually sandblasted with an alumina powder. The pontic is usually made from dental porcelain. The whole restoration is thus a

Current cement brands commonly used for this procedure include Panavia, Nexus. All are either auto cure or dual cure to ensure complete polymerisation of the resin under the wing.

Contradictions

According to dentists in different cosmetic dentistry los angeles centers, great care must be taken during cementation to avoid contamination of the operative field as this will lower the bond strength of the cement and lead to premature failure. For this reason, rubber dam is often advocated for placement, though this can bring its own difficulties.
