What is a Porcelain Onlay?
A porcelain onlay is similar to an inlay but includes one or more of the chewing cusps if they are affected. It is sometimes referred to as a partial crown. Onlays are ideal for repairing teeth with large fillings or decay while conserving more natural tooth structure compared to a full crown.
Reasons for Porcelain Onlays:
- Broken or fractured teeth
- Cosmetic enhancement
- Decayed teeth
- Fractured fillings
- Large fillings
What Does the Procedure Involve?
- First Appointment:
- Highly accurate impressions (molds) of the tooth are taken.
- A temporary restoration is placed to protect the tooth while the onlay is fabricated by a dental laboratory.
- Decay or old filling material is removed, and the tooth is prepared to fit the onlay.
- Second Appointment:
- The temporary restoration is removed.
- The custom onlay is cemented into place with precision.
- Bite and fit are adjusted as necessary.
- Aftercare:
- Follow good oral hygiene practices, maintain a proper diet, and attend regular dental visits to ensure the long life of your onlay.
Durability:
Porcelain onlays are highly durable and long-lasting, though they may eventually need replacement, just like other dental restorations.
Additional Notes for Both Inlays and Onlays
- Both restorations provide a natural look that blends with your existing teeth.
- They are excellent alternatives to full crowns when preserving tooth structure is a priority.
- CEREC technology may allow for same-day restorations in selected cases.
Careful planning and professional placement are essential for optimal results
