The appearance of your smile can be improved with the use of a removable partial to replace one or more of the teeth that have been lost. They have the appearance of natural teeth, function like natural teeth, and are less expensive and invasive than permanent partial dentures. Dentures can either be complete or partial, depending on their coverage. The number of teeth that a removable partial denture replaces all at once is what distinguishes it from a full denture. A full denture is a full-coverage prosthetic device that replaces an entire dental arch. When compared to complete dentures, removable partial dentures fill in specific gaps in the mouth rather than the entire mouth like a complete denture does.
RPDs, also known as removable partial dentures, are false replacement teeth that are attached to a gum-colored plastic base and are removable from the mouth. This denture base will rest in your mouth like a retainer tray, snugly fitting up against your gum line and covering any empty spaces in your mouth with fake teeth. Claps made of metal or plastic are attached to the teeth that surround the RPD, which are in good health. These teeth are referred to as the abutment teeth. These clasps are typically made of metals like titanium or chrome, and they are designed to easily attach to the teeth that surround them in order to provide a snug fit. These clasps are essential to the functionality of an RPD, and if they are not fitted properly, they have the potential to damage the patient’s gums and remaining teeth.
Some components of removable partial dentures
Each and every type of partial denture may contain the following components:
- The saddle: The dentists refer to the partially edentulous region of the mouth as the saddle area. The saddle, also known as the base, is composed of artificial teeth that will be placed over the saddle area. Either the tissue in the mouth or the teeth can support these saddles. In the event that the edentulous area, also known as an area with missing teeth, does not have a terminal tooth to attach to, this base can be modified, and a distal extension base may be used in its place.
- Retainers: Through the use of abutment teeth, direct retainers are able to fit securely and comfortably against the gum tissue. Examples of this type of attachment include clasps and various other precision fasteners. For the purpose of better securing the denture to the teeth, each clasp will be equipped with a reciprocal arm, a retentive arm, and an occlusal rest. There are, however, a number of different clasps from which to choose, and each one is intended to work with a distinct case. Clasps can be found in a variety of forms, including wrought clasps, bar clasps, and cast circumferential clasps. Indirect retainers, on the other hand, hold the denture saddle in place within the mouth by utilizing a variety of minor connectors and rests.
- Connectors: A removable partial may have either major or minor connectors, depending on the situation. The major connector is the unit that connects one side of the arch to the other and is also the point to which all of the other components are either directly or indirectly connected. It does this by joining the two ends of the arch. The major connector, on the other hand, is what connects to other denture components like clasps and occlusal rests. These components are connected to the major connector via the minor connector.
- Occlusal rests: An occlusal rest is a rigid extension in the denture form that is placed in rest seats to assist in supporting the overall structure of the partial dentures . Occlusal rests are also known as occlusal extensions. The term “rest” refers to any component of a denture that provides vertical support, and “rest seat” refers to any surface of an abutment that has been prepared specifically to receive the rest.
