Porcelain Crowns are usually the best treatment option when there is too much tooth structure missing. Crown can strengthen the tooth and also provide great appearance and correct alignment. The commonly used materials are as following (in our office):
- All Porcelain
- Porcelain-fused to metal
- Gold alloys (rare)
All porcelain crowns used to be used only for the front teeth for the natural looking appearance and the beauty but lacked strength. However, the newer porcelain crowns are much stronger; and we could place in the back teeth as well. Crown is cemented over the treated tooth.
Porcelain Inlays and Onlays
When you have a moderately sized piece of tooth that has broken off or decayed, a filling is usually not appropriate. Everyday biting and chewing would just cause a smaller restoration to break off or compromise the overall integrity of the tooth. But completely crowning the tooth goes beyond what is actually needed.
Inlays and onlays offer the perfect medium for repairing teeth in a conservative manner.
Sometimes called “three-quarter crowns,” dental inlays and onlays cover or fill damaged tooth structures and restore overall shape to the tooth. They cover approximately 2/3 to 3/4 of the tooth surface, reinforcing areas that are impacted by fractures or cavities.
