Onlays
Onlays are a type of dental restoration used to repair teeth that have been damaged by decay or trauma but still have enough healthy structure to avoid a full crown. They are often referred to as partial crowns because they cover a larger area of the tooth than a filling but not the entire tooth like a crown.
Procedure Overview
Examination
The dentist examines the tooth and takes x-rays to assess the extent of the damage.
Preparation
The damaged or decayed portion of the tooth is removed, and the tooth is shaped to receive the onlay
Impression/scan
An impression or digital scan of the tooth is taken to create a custom-fit onlay.
Temporary Onlay
A temporary onlay may be placed while the permanent one is being made in a dental laboratory.
Fitting
Once the permanent onlay is ready, it is fitted, adjusted, and bonded to the tooth using dental cement.
Polishing
The onlay is polished to ensure a smooth and natural finish.
Benefits
Durability
Onlays are made from strong materials like gold,ceramic or composite resin, making them more durable than traditional fillings.
Aesthetics
Ceramic and composite onlays can be colour-matched to your natural teeth, providing a seamless appearance.
Preservation
Onlays help preserve more of the natural tooth structure compared to crowns.
