Onlay restorations are larger restorations reserved for teeth that require more structural support due to large decay, fractures, or failing large existing traditional fillings. Onlays are custom made by the dental laboratory using either traditional cast gold alloy or a solid tooth colored dental ceramic material that is then permanently cemented into your tooth as a restoration.
Onlays are often referred to as a partial crown. They provide the support of a traditional crown only where it is needed, while maintaining much more of the natural tooth structure that would otherwise be lost if a traditional full coverage crown was required.
Indications for onlay restorations:
- Large decay in teeth
- Large fractures in teeth
- Cusp fractures
- Aesthetic or more durable replacement of old fillings
Porcelain and gold onlays are but one choice for restoring your teeth. All dental materials have certain advantages and disadvantages but no dental material is capable of lasting forever. As your dentist, I will always advise you on the best material choices for any given situation based upon your needs, dental research, and my experience. Of course excellent oral hygiene practices, good dietary habits, and regular dental visits to my practice will aid in the life of any restoration.
