Crowns and bridges are typically made of metal alloys, porcelain-fused-to-metal alloys (PFM) or all ceramics. The material selected differs in strength, after care maintenance and aesthetics:
1. Metallic crowns
stainless steel metal alloy or all gold crowns provides good strength. All gold crowns is adaptive but can be expensive and wiil be visible.
2. PFM crowns
Porcelain-fused-to-metal alloys are made in the dental laboratory with ceramic glass material on outer with varying metallic alloys on the inner sub-structure. PFM crowns is tooth-colored for natural-looking aesthetics and has inner
3. All ceramic crowns
Like PFM crowns, all ceramic crowns are made in dental labs but do not contain any metals. This allows high asethetics whereby crowns mimics natural teeth. With advancements in today’s materials, zirconia ceramics crowns provides for good strength on both anterior and posterrior teeth.
4. Composite crowns
Temporary crowns rae normally made from composite resins that is completed at chairside during one visit. Composite crowns provides for quick restorations. It is however not as strong in comparison to ceramic crowns and may chip. The color shades of composites may also change over the long run and will need replacement.
