Metal Ceramic Dental Crown

Metal Ceramic Dental Crown is a restoration that reproduces the entire surface anatomy of the clinical crown of a tooth. It is fabricated with porcelain fused to metal casting. Its abutment can be a prepared tooth or an implant abutment. The prepared tooth abutment may be sound, or it may be partially rebuilt by a cast metal core or a cast core and post, cemented to the remaining tooth structure, or by composite resin or by amalgam.

Metal-Ceramic Alloys for Porcelain Bonding
1. They had higher melting temperatures (due to greater palladium content) to accommodate the temperatures required for porcelain application.
2. They contained little, if any, silver which could cause the porcelain to turn green.
3. They contained little, if any, copper because it could cause the alloy to sag during porcelain firing.

Indications for Porcelain Fused to Metal Dental Crowns
1. The tooth should have extensive restorations and be required as an abutment for an RPD.
2. It should be a heavily restored tooth and should oppose a natural tooth with no other vertical stops on the side of the arch.
3. Porcelain Fused to Metal Dental Crowning is the only way to improve esthetics.
4. Porcelain Fused to Metal Dental Crowning is required to correct the integrity of the occlusal plane.
5. An endodontically treated multirooted tooth is under extensive load from a natural dentition.
6. Extensive Strength is needed for the final restoration.

Kapag umabot na sa pulp, kailangan iroot canal treatment muna bago pastahan or crown. For more info about dental crowns visit: http://costdentures.com/fixed/metal-ceramic-crown/ […]
