Study Notes
Retention in Removable Partial Dentures
- Support is the factor that is achieved by the intimate relationship of the denture base and the rigid major connector to the underlying soft tissues.
Components of Removable Partial Dentures
- Direct retainers are defined as any type of clasp, attachment, or device used for the fixation, stabilization, or retention of a prosthesis.
Resistance to Dislodgement
- Stability is the quality inherent in the removable partial denture that resists the vertical forces of dislodgement.
Gilan Youssef Altonbary
- Gilan Youssef Altonbary is associated with the University of Aleppo.
Abutment Tooth
- Encircling an abutment tooth in such a manner as to resist displacement of the prosthesis away from basal seat tissues achieves retention.
Clasp Assembly
- The function of the retentive arm in a clasp assembly is to resist displacement of the prosthesis away from basal seat tissues.
- The minor connector is the component of the clasp assembly that must be rigid and joins the body of the clasp to the remainder of the framework.
Prothero's Advanced Cone Theory
- The line formed at the junction of the cones represents the path of insertion.
Reciprocal Arm
- The reciprocal arm connects the rest and shoulder of the clasp to the minor connector.
- In dental prosthetics, the reciprocal arm functions to resist the tendency of the retentive arm to dislodge the prosthesis.
Rest in Clasp Assembly
- The primary function of the rest in a clasp assembly is to distribute the load to the abutment tooth.
Terminal End of Retentive Clasp Arm
- The terminal end of the retentive clasp arm is called the terminal shank.
Classic Clasp
- A classic clasp consists of a minor connector, truss arm, tail, tang, upright arm, and clasp stalk.
Dental Surveyor
- A dental surveyor helps identify areas of retention and undercuts in partial denture retention.
Learn about the factors affecting the retention of removable partial dentures and the quality inherent in them that resists vertical forces of dislodgement. This quiz covers topics such as the force of gravity, adhesiveness of foods, and the forces associated with the opening of the jaws.
