A filling may be insufficient after decay, fracture or loss of tooth structure. A crown covers the remaining tooth; its need and more conservative options are assessed during examination.
Which Type of Crown Is Right for You?
Material selection depends on remaining tooth structure, tooth position, bite forces and appearance expectations. Every material has limitations and care requirements.
1. Zirconia Crowns: Natural Appearance and Strength
Zirconia is a ceramic used in dental restorations, not a metal alloy. Selection depends on tooth position, bite and clinical requirements.
- Suitability: Zirconia may be used in different restorations; appearance, strength and gum relationships require individual assessment.
2. All-Ceramic Crowns
All-ceramic crowns can be made from different ceramics. Appearance, fracture risk, preparation requirements and suitable uses vary by material.
3. Porcelain-Fused-to-Metal Crowns
A metal-ceramic restoration has porcelain over a metal framework. Span, loading, appearance and individual sensitivities are considered when choosing materials.
- Suitability: Porcelain fused to metal may be considered for some posterior teeth or bridges.
4. Stainless-Steel Crowns for Children
Stainless steel crowns may restore selected primary teeth. Need and service duration depend on the tooth’s condition.
Restoration Preparation with CAD/CAM
Digital impressions and computer-assisted manufacture may be used for some restorations. Same-day completion is not suitable for everyone; necessary treatment, try-in and laboratory stages remain essential.
How Does the Process Work?
- Digital scan: An intraoral scanner may take impressions where suitable. Conventional impressions may also be needed.
- Design: Your crown is designed digitally to suit your tooth, bite, and facial features.
- Manufacture: The restoration is made, finished and checked in the mouth. Total time is not limited to the machine’s operating time.
What Is Assessed Before a Crown?
Remaining tooth structure, decay, cracks, gums and bite are assessed. More conservative options such as a filling or partial restoration may be possible. Tooth reduction is irreversible; discuss sensitivity, possible root canal treatment and future replacement.
