Ceka Attachments. Retainer: A component of a partial denture that provides both retention and support for the partial denture When a distal extension RPD is considered, an indirect retainer should be incorporated into the framework in order to prevent upward rotational movement of the denture. Abutment: A tooth that supports a partial denture. Featuring adjustable retention, the design satisfies the criteria for esthetics, retention, support and stability for a tooth-borne maxillary RPD. Traditionally, removable partial denture (RPD) design has focused on biomechanical aspects such as stability, retention, loading of supporting tissues, and mechanical durability. Jing Zhao, Xinzhi Wang, in Advanced Ceramics for Dentistry, 2014. Support: Resistance to movement towards the tissues or teeth 7. RPD DESIGN: CONSIDERATIONS IN SUPPORT, STABILITY AND RETENTION MWANGI A. M. MWANGI C. W. 23.10.2014 Retention Def: the ability of the prosthesis to resist dislodgement in a direction opposite its path of insertion Types of retention: Direct retention Indirect retention Passive retention Direct retention Can be provided by: Clasps/ extra-coronal attachments Precision … After designing support, stability and retention, other parts should be considered. Abutment: A tooth that supports a partial denture. Stability: Resistance to movement in a horizontal direction (anterior-posteriorly or medio-laterally 6. Unique female contacts a greater surface area of the sphere for increased retention and stability. Risk Factors in Traditional Design The majority of prosthodontic textbooks have con-centrated on the RPD design principles of force dis-tribution, support, stability, and retention. Removable partial denture (RPDs) as the names suggests, is not fixed permanently in the patient’s oral cavity and can be easily removed by the patient. Acknowledgements: The authors thank Jeffrey P. Miles, DDS, an associate professor at the University of the Pacific Arthur A. Dugoni School of Dentistry, for the illustrations in Figure 3 and Figure 4. 3-9). The True Precision of the Ceka Revax systems provide for hinge, vertical, and rotational movements to provide maximum abutment protection. Stability also depends on the manner in which the patient uses the prosthesis (Fig. The fit, retention and stability of the RPD foundation is verified again and checked with the pressure indicating paste for uniform tissue compression during connecting male attachments. The purpose of this study is assessing the quality of the frameworks made in the department of prosthodontics, Qazvin school of dentistry, regarding their causes of malfunction, retention, stability, and support. metal components that supply strength, retention, stability, and support of partial denture. Support: Resistance to movement towards the tissues or teeth 7. Stability of a RPD is obtained by all the factors which provide support, retention, reciprocation, bracing, indirect retention, occlusion, and connection. Learn More About Sagix. A denture properly designed and constructed to make The … The most Stability: Resistance to movement in a horizontal direction (anterior-posteriorly or medio-laterally) 6. 3.3.3 Removable Partial Dentures. 38. Troughs for the extensions of the intra-coronal attachments are made to have some space around extensions. 8. 8. Retainer: A component of a partial denture that provides both retention and support for the partial denture As with FPDs, the RPD can also restore an incomplete dentition, but with broader indications because of not-so-strict prerequisites. ple shape.37 There is significant support in the liter-ature for the view that gingival/periodontal health is favored by the open/hygienic design. Retainer (Clasp) Assembly A Clasp (retainer) assembly is a combination of several RPD components that engage an abutment tooth extra-coronally for support, stability and retention of the partial denture.
