Porcelain Jacket crowns, all-ceramic dental crowns (non-zirconium)

All porcelain dental crowns provide better natural colour match than other crown type and may be more suitable for people with metal allergies. However, they are not as strong as porcelain fused to metal crowns or zirconium crowns and they wear down opposing teeth a little more than metal or resin crowns. All-ceramic crowns are a good choice for front teeth.
