What are the components of RPD?
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. 3-1). Each component or part one or more functions necessary for the operation of the RPD.
What are the parts of denture?
Generally speaking, any removable partial denture includes the following components: the saddle, direct retainers, indirect retainers, connectors, and incisal and occlusal rests. Each of these components helps the denture work efficiently within the mouth.
What are the three parts of denture?
Parts of a complete denture (1) Denture base (2) Denture flange (3) Denture teeth (4) Denture border [2].
What is distal extension RPD?
Movements of a Distal Extension RPD Rotation of the prosthesis around a fulcrum line passing through the two principal occlusal rests of the direct retainer or through the points where the minor connectors adjacent to the edentulous area break contact with the tooth surface.
What is the saddle in dentistry?
The saddle is the part of the denture that carries the artificial teeth over the edentulous area or saddle area. Saddles may be designed as mucosa-borne to transmit the occlusal load through the mucosa (Figure 3.3. 1) or tooth-borne, where occlusal rests transmit the load to the adjacent teeth (Figure 3.3. 2).
What is bracing in RPD?
1.Covering the sides of the residual. ridges with the denture bases. 2. Bracing the sides of the teeth by means of rigid clasp arms.
Can you have a single tooth denture?
When you think of the word “denture” you may think of a full set of false teeth but that’s not always the case. Yes, full dentures can be used to replace a whole set of teeth but you can also have a removable partial denture to fill the gap from just one missing tooth.
What is a spoon denture?
A maxillary provisional removable dental prosthesis, without clasps, whose palatal resin base resembles the shape of a spoon. The resin base does not contact the lingual surfaces of the teeth and is confined to the central portion of the palate.
What is minor connector?
A MINOR CONNECTOR is the connecting link between the major connector or base of a RPD and the other units of the prosthesis, such as clasps, indirect retainers, and occlusal rests. 1. Minor connectors join. the major connector with other parts of the RPD. 2.
What is the difference between RPD and fixed partial dentures?
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. 3. Implant supported prosthesis – most costly, closest replacement to natural dentition, less costly over long term 4.
What are the components of a definitive RPD?
CHAPTER 3 COMPONENT PARTS OF AN RPD AND THEIR FUNCTIONS. INTRODUCTION. 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. 3-1).
What are the components of a partial denture?
E. Components of a Partial Denture a. Major Connector: The unit of a removable partial denture that connects the parts of one side of the dental arch to those of the other side. It’s principal functions are to provide unification and rigidity to the denture.
What are the indications for RPD’s?
D. Indications for RPD’s 1. lengthy edentulous span (too long for a fixed prosthesis) 2. no posterior abutment for a fixed prosthesis 3. excessive alveolar bone loss (esthetic problem) Table of Contents – 2 4. poor prognosis for complete dentures due to residual ridge morphology 5.
