Study Notes
Bridge
- A bridge is a dental restoration used to replace missing teeth.
- It is permanently attached to the adjacent teeth or dental implants.
- It can be either fixed or removable.
Bridge Components
- Pontic: The artificial tooth that replaces the missing tooth.
- Retainer: The part of the bridge that is attached to the natural teeth or implants.
- Abutment: The natural teeth or implants that support the bridge.
Bridge Classification
According to Retention
-
Fixed Bridge: A permanently fixed structure with cemented abutments.
- Fixed-Fixed Bridge: Pontic and retainers are soldered at both ends and cemented to abutments.
- Fixed-Support Bridge: Connected to a retainer at one end with a soldered joint and a non-rigid connector at the other end, allowing abutment movement.
- Fixed-Free (Cantilever) Bridge: Supported at one end by retainers while the other end is unsupported.
- Spring Cantilever Bridge: A cantilever bridge with a resilient curved arm resting on the palate, supported by an abutment away from the edentulous area.
- Removable Bridge: Attached to the abutment teeth with clasps or other attachments.
- Compound Bridge: Combines two or more simple bridge types.
According to Material
- All Metal Bridge: Constructed entirely of metal.
- All Non-Metallic Bridge: Made entirely of acrylic or ceramic.
- Metal-Ceramic Combination Bridge: Made of a metal substructure covered with ceramic.
According to Position
-
Anterior Bridge: Replaces teeth in the front of the mouth.
- Unilateral Anterior Bridge: Replace missing teeth on one side of the mouth.
- Bilateral Anterior Bridge: Replace missing teeth on both sides of the mouth.
- Posterior Bridge: Replaces teeth in the back of the mouth.
- Complex Bridge: Extends from the anterior to the posterior arch, passing the canine area.
Resin Bonded Bridge (Maryland Bridge)
- Constructed with cast metal or partial veneer bonded to etched enamel.
- Known as a minimal preparation bridge.
Implants
- Inert materials implanted into oral tissues beneath the mucosa or periosteal layer, providing retention and support for fixed or removable prosthesis.
