Study Notes
Cerec Technology
- Cerec technology uses ceramic to make crowns more durable than composite fillings.
- Cerec technology can save money by reducing laboratory fees.
Fixed Prosthodontic Treatment: Bridges
- Bridges are used to replace missing teeth in the same arch.
-
Fixed Bridge
- A fixed bridge uses multiple units joined together, the number of units is based on the number of teeth missing.
- Abutments (anchor teeth) can be natural teeth or titanium cylinders placed on dental implants.
- Did You Know? A good rule of thumb for longer bridges (more than one tooth missing) is to use one abutment on the posterior and a double abutment on the anterior portion of the bridge to support the missing teeth.
-
Resin-Bonded Bridge
- Also known as a Maryland bridge.
- Contains a resin or porcelain pontic bonded to the lingual surfaces of the adjacent teeth with resin wings.
- Not used often because it is unpredictable and often needs re-cementing.
- Most commonly used to replace missing front teeth.
Fixed Prosthodontic Treatment: Inlays, Onlays, and Veneers
- These restorations are permanent, unable to be reshaped or removed by the patient.
-
Inlays
- Replace missing tooth structure within the tooth.
- Used when there is not enough healthy tissue for a regular restoration but not enough damage to require a crown.
- Ideal when tooth destruction is less than half the distance between cusp tips.
-
Onlays
- Similar to inlays, replacing missing tooth structure.
- Cover more of the tooth than inlays.
-
Veneers
- Thin layers of composite or porcelain placed over a tooth for cosmetic purposes.
