Porcelain Fused To Metal Crowns Cost
Metal Ceramic Crowns is Ideal For Back Teeth. It is a material Reliable Strong, And Robust Type Of Crown. In Dentistry Know A Days They Are A Little Outdated As Many Patient Would Rather Have A All Ceramic Restoration. PFM Crowns Consist Of A Metal Interior Or Base Which Is Fused with The porcelain.

PFM Advantages And DisAdvantages
PFM Crown Steps Mexico – Manufacturing And TimeFrames
1- The material presents as powder to be mixed with liquid forming a slurry that is used to build the restoration up
2- The ceramic ingot is fused and cast in a refractory (investment) mold made by the lost wax technique
3- Base Metal Alloys – most popular for PFM’s. Contain NO noble metals – “Non-Precious
4- Metal is relatively stable when is solid, the metal mold it must be heated beyond its melting range. When cooled, metal forms a crystalline solid.
Bonding of porcelain to the metal Copings. Certain metal system (electro-forming) requires the application of specific bonding paste before building-up the porcelain.

These restorations are composed of; Metal substructure (Coping) supporting a ceramic veneer those are chemically and mechanically-bonded together.
PARTS OF PFM
( PORCELAIN FUSED TO METAL)
These restorations are composed of; Metal substructure (Coping) supporting a ceramic veneer those are chemically and mechanically-bonded together
Core: cast metallic framework. Also known as coping.
Opaque porcelain : first layer consisting of porcelain modified with opacifying oxides
Mask the darkness of the oxidized metal framework
Final buildup of dentine and enamel porcelain.
Bonding of porcelain to the metal copings
– Infiltration (flow) of the fused ceramic into the surface irregularities of the metal coping.
– Sandblasting of the metal surface or using plastic beads during waxing are important for this issue.
– Ionic bond between the metal oxide layer and the opaque porcelain.
– Metal degassing is important for oxide formation, removing the surface contaminants and greases.
– Thin oxide layer (in case of noble alloys) provides stronger bond than the thick one (in case of base metal alloys).
Coeff. of thermal expansion mismatch:
As a result of higher metal contraction on cooling,
– The fused porcelain will be sucked (attracted) more strongly into the metal surface irregularities.
– Residual compressive stresses will developed in and strengthen the porcelain.
Application of a special bonding agent:
Certain metal system (electro-forming) requires the application of specific bonding paste before building-up the porcelain.
