components of rpd

Removable partial denture (RPD) is one of the various treatment options available for the replacement of teeth for partially edentulous patients. All definitive RPDs will have the following components: (1) a major connector, (2) several minor connectors, (3) two or more direct retainers, (4) one or more denture bases, and (5) one or more prosthetic teeth (Fig. !�����}F5�po���3�n���ͯ�爎0jDf' W��h���E3�S>#]���Gm[�g�����{��G&b�����9N� �@_V�q���i�h���pd���a\y4Z~0ʬ�T���nN#(B���A_���SZ@��+�W )�R�+U�h^��W�q�ɬd�/j�>r���2����_k\2��Aͽ�"�Rc���s��.ݝ_�3��1'~ҪM.�����n�oϡk��I�+}����If�����ӿ��� 8#, b.

Contributes to support the prosthesis. Components of RPDs 1. The components of a removable partial denture that serve primarily to transfer forces occurring against the prosthesis down the long axis of the abutment teeth are called rests, and a rest seat is the prepared surface of a tooth or fixed restoration into which a rest fits. Fixed partial denture – requires abutments at opposite ends of edentulous space, more expensive than RPD, must grind down abutments, flexes and can fail if too long. This program reviews some of the basic principles of RPDs and outlines the reasons why patients often select RPD treatment as opposed implant therapy when cost factors and anatomic limitations and other factors are taken into consideration. 24. The major connector of an RDP is the component that connects the different parts of the RPD as well as can achieve numerous functions and influence the success of RPD. 6.

INDIRECT RETAINER- The component of rpd which assists the direct retainer in preventing displacement of distal extension base by acting through lever action on the opposite side of the fulcrum line when the denture moves away in pure rotation around the fulcrum line. The load transfer characteristics of various RPD designs are important for best prognosis and longevity. Improvement with FPD was more frequent than with RPD for several perceptions.l Despite the slight superiority of the FPD in terms of patient satisfaction, lack of functional differences and success rates do not support the selection of implant-supported FPD over RPD, without consideration of other factors. The four basic components involved in an RPD are the artificial teeth, the denture base, retainers, and connectors (Figure 3.17). 48.
