Pfm crown cost: Dental crowns have enhanced the life of many. These are cap-shaped that are used to cover, protect, or restore the shape, colour, or size of the original tooth. There are different types of crowns.
If a person suffers from dental issues, then it causes a lot of problems. Dental crowns help a person to smile openly and enjoy food. If a person has pain in a tooth, then he/she is not able to live life to the fullest. Star dental crown is a leading brand that provides artificial dental crowns and bridges. PFM crowns are also available. You can enquire about pfm crown cost to know more about them.
PFM is a popular choice in India. PFM stands for Porcelain Fused to Metal. The outer layer of PFM is covered with porcelain. It provides good aesthetics and gives a natural appearance to the tooth. Metal is used as the base to provide strength. The porcelain layer may wear off with time and metal may become visible.
It is important to maintain oral hygiene. It becomes much more important when the crown is used. Brushing teeth twice a day and regular dental check-ups are important precautions to avoid cavities beneath the crown.
All-Porcelain | Porcelain Fused to Metal | Zirconia Metal | |
General Description | Porcelain, ceramic or glasslike fillings and crowns | Porcelain is fused to an underlying metal structure to provide strength to a crown or bridge | Zirconia metal result in strong, effective crowns and bridges |
Principal Uses | Inlays, onlays, crowns and aesthetic veneers | Crowns and fixed bridges | Crowns and Fixed bridges |
Durability | May fracture under heavy biting loads | Very strong and durable | High corrosion resistance prevents tarnishing; high strength resists fracture and wear |
Preparation Consideration | Strength depends on adequate porcelain thickness; it requires oderate tooth reduction during preparation | Including both porcelain and
metal creates a stronger
restoration than porcelain
alone; moderately aggressive tooth reduction is required |
We can make a full zirconia crown with only 1mm of space |
Resistance to Wear | Highly resistant to wear, but porcelain can rapidly wear opposing teeth if its surface becomes rough | Highly resistant to wear, but porcelain can rapidly wear opposing teeth if its surface becomes rough | Highly Resistant to wear and gentle to opposing teeth |
Resistance to Fracture | Prone to fracture when placed under tension or on impact | Porcelain is prone to impact fracture; the metal has high strength | A full zirconia crown is virtually indestructible |
Biocompatibility | Well tolerated | Well tolerated, but some patients may show allergenic sensitivity to base metals | Zirconia is a 100% biocompatible material |
Post-Placement Sensitivity | Low thermal conductivity reduces the likelihood of discomfort from hot and cold | High thermal conductivity
may result in early postplacement
discomfort from hot and cold |
High thermal conductivity may result in early postplacement discomfort from hot and cold |
Esthetics | Color and translucency mimic natural tooth appearance | Porcelain can mimic natural tooth appearance, but metal limits translucency. | Metal colors mimic natural teeth |
Relative Cost/Visits | Near about 3 times higher to Porcelain fused to metal; requires at least two office visits and laboratory services | Requires at least two office visits and laboratory services | Priced nearly same as All Porcelain and requires the same amount of procedure time |
