Inlays:

• Purpose: Inlays are used to restore a tooth that has mild to moderate decay or damage but still has sufficient healthy tooth structure to support the restoration.
• Material: Inlays are typically made from materials like porcelain, composite resin, or gold.
• Procedure:
  • The dentist removes the decayed or damaged portion of the tooth.
  • An impression or digital scan of the prepared tooth is taken.
  • The inlay is custom-made in a dental laboratory based on the impression or digital scan.
  • Once the inlay is ready, it is bonded to the prepared tooth using dental cement.

Onlays:

• Purpose: Onlays are used when the damage or decay extends to one or more of the cusps (the pointed parts) of a tooth. They are more extensive than inlays and provide additional coverage for the cusp or cusps.
• Material: Similar to inlays, onlays can be made from materials like porcelain, composite resin, or gold.
• Procedure:
  • The dentist removes the decayed or damaged portion of the tooth, including one or more cusps if necessary.
  • An impression or digital scan is taken.
  • The onlay is custom-made in a dental laboratory based on the impression or digital scan.
  • The onlay is then bonded to the prepared tooth using dental cement, providing coverage for the damaged or missing cusps.

Advantages:

• Both inlays and onlays allow for the preservation of more natural tooth structure compared to traditional dental crowns, which require more extensive tooth preparation.
• They are custom-made to fit the specific dimensions of the prepared tooth, ensuring a precise and comfortable fit.
• Inlays and onlays are durable and provide long-lasting restoration of teeth.
