______ fixed partial denture is used when support can be obtained only from one side of the edentulous space. These dentures have compromised support. The abutment teeth on the supporting side should be strong enough to withstand the additional torsional force.

<p>Cantilever</p> Signup and view all the answers

Very conservative design especially when a single abutment is involved. When secondary abutments are used, parallel preparation can be easily obtained because the abutments are adjacent to another. Easy to fabricate. Produces torquing forces on the abutment. Cannot be used to restore long span edentulous spaces. Minor design errors can affect the abutments in a large scale.

Dentures with or without preparation, which have a truly adhesion-based retention system, as there is no macromechanical retention on the metal surface of bridges, the surface of which is simply oxidized and bonded with organosilane adhesives.

<p>Adhesive Bridge</p> Signup and view all the answers

Has rigid connectors at both ends of pontics which forms a rigid prosthesis. The abutment teeth are therefore rigidly splinted together, and for a conventional bridge must be prepared parallel to each other so that the bridge, which is a minimum of three units, can be cemented in one piece. The retainers should have approximately the same retention as each other to reduce the risk that forces applied to the bridge will dislodge one retainer from its abutment, leaving the bridge suspended from the other abutment.

Can be used for diastema cases. Metal crown retainers that require minimal tooth preparation, can be used in posterior teeth to replace missing incisors. The connector bar may interfere with speech and mastication. Deformation of the connector bar may produce coronal displacement of the pontic. There may be food entrapment under the connector bar, which may lead to tissue hyperplasia.

Study Notes

Bridge Design

  • When a single abutment is involved, a cantilever bridge design is especially conservative.
  • Cantilever bridge design produces torquing forces on the abutment.
  • A bridge design that uses a retention system that is adhesion-based with no macromechanical retention on the metal surface is called an adhesive bridge.
  • A fixed-fixed bridge design has rigid connectors at both ends of pontics and forms a rigid prosthesis.
  • A bridge design that allows some vertical moment of the mesial abutment tooth is called a cantilever bridge.

Abutment and Pontic

  • The function of an abutment is to provide attachment and support for a bridge.
  • A pontic is an artificial tooth that is suspended from the abutments.
  • The primary function of a pontic is to replace a missing tooth or teeth.

Retainer and Connector

  • A retainer is a component that is cemented to the abutments to provide retention for the prosthesis.
  • The primary function of a retainer is to provide retention for the prosthesis.
  • A connector is a component that joins the pontic to the retainer and may be rigid or non-rigid.

Saddle (Edentulous Space)

  • A saddle is the area of edentulous ridge over which the pontic will lie.
  • The purpose of a saddle is to provide a space for the pontic to replace a missing tooth or teeth.

Conventional Bridge

  • A conventional bridge is the most commonly used type of fixed partial denture.
  • The design of a conventional bridge involves fabrication of a fixed partial denture, which takes support from abutments on either side of the edentulous space.
  • A conventional bridge has rigid connectors at both ends of pontics and forms a rigid prosthesis.
  • The retainers of a conventional bridge should have approximately the same retention as each other to reduce the risk of forces applied to the bridge dislodging one retainer from its abutment.

Other Types of Bridges

  • A Maryland bridge is a type of bridge that uses a retention system that is adhesion-based with no macromechanical retention on the metal surface.
  • A spring cantilever bridge is a type of bridge that has a movable connector that allows some vertical moment of the mesial abutment tooth.
  • A material combined metallic with labial or buccal veneers bridge is a type of bridge that uses a combination of materials to provide maximum retention and strength.
  • A fixed-removable bridge is a type of bridge that allows units to be cemented as individual sections and does not need preparations to be parallel to each other.

Important Notes

  • Cantilever bridges are used when support can be obtained only from one side of the edentulous space.
  • Cantilever bridges have compromised support and may interfere with speech and mastication due to the connector bar.
  • The abutment teeth on the supporting side of a cantilever bridge should be strong enough to withstand the additional torsional force.
  • Minor design errors can affect the abutments in a large scale in a cantilever bridge.
  • A fixed-fixed bridge is more complicated to construct in the laboratory than a fixed-removable bridge.
  • A fixed-removable bridge is more conservative of tooth tissue and can be used for diastema cases.
