What is support in complete denture?

What is support in complete denture?

Support Of Complete Denture. Support , is defined as the resistance to vertical forces of mastication ,occlusal. forces and other forces applied in a direction towards to denture bearing area.

What is support RPD?

Each component part of an RPD will provide one or more of the following functions: Support: Resistance to movement of the prosthesis toward the edentulous ridge. Support is the means by which occlusal forces are transferred to the teeth and denture bearing tissues for dissipation (Fig. 3-2).

What is stability in denture?

STABILITY. “the resistance against horizontal movements and forces that tends to alter the relationships between the denture base and its supporting foundation in horizontal or rotatory direction.”

How do you achieve stability in complete dentures?

Brill (1967)- stated that the 3 important factors essential for stability in complete denture are maximum coverage of the denture bearing area, good peripheral seal, equalization of pressure.

What is the difference between retention and stability?

Denture fit is usually described in terms of reten- tion and stability. Retention is defined as movement in the vertical plane and stability as movement in the horizontal plane. 1 Clinically, denture movement is assessed subjec- tively either by examination or the use of qualitative scales.

What is the retromolar pad?

The retromolar pad is a mass of soft tissue located at the posterior end of the mandibular alveolar ridge. This pad covers the underlying bone with surrounding attached muscle fibers. Sicher described retromolar pad as a triangular soft elevation of mucosa that lies distal to third molar [1].

How is an overdenture supported in the mouth?

An overdenture, as its name implies, is designed to go over a supporting structure. This could be natural teeth, but more often dental implants are used. In the upper jaw, the supporting structure for an overdenture is generally a metal frame anchored by three or more implants.

What is retention in RPD?

RETENTION is resistance to movement of a denture away from the teeth and/or tissues along the path of placement of the prosthesis. Most retention of RPDs is provided by DIRECT RETAINERS which are clasp assemblies or attachments applied to an abutment tooth to retain an RPD in position.

What is the most stable area for support of a mandibular complete denture?

The lingual flange of the mandibular denture should be turned into the anteroinferior part to produce maximum stability for the denture since no muscle lies directly underneath.

What is the Retromolar pad?

What is a molar pad?

A cushioned mass of tissue, frequently pear-shaped, located on the alveolar process of the mandible behind the area of the last natural molar tooth.

What are implant supported denture?

An implant-supported denture is a type of overdenture that replaces several teeth at once. If you’ve lost most of your teeth, we may recommend implant-supported dentures. Your overdenture will need at least two dental implants for support. However, our dentist typically recommends all-on-6 implants for the best result.

What is overdenture attachment?

Implant overdenture attachment systems are comprised of two parts, one part connected to the implant/bar and the other within the prosthesis. The matrix is the receptacle component and a corresponding patrix fit closely either mechanically or by friction.

What is pier abutment?

Pier abutment, also named inter- mediate abutment, is defined by the Glossary. of Prosthodontic Terms as a natural tooth. located between terminal abutments that. serve to support a fixed or removable dental.

What is a fulcrum line?

A fulcrum line is a theoretical line around which a removable dental prosthesis tends to rotate when subjected to forces towards or away from the residual ridge. This movement away from the residual ridge around the fulcrum line can be prevented by the action of an indirect retainer, (Fig.

What is denture bearing area?

Those surfaces of the teeth and edentulous ridges covered by a denture.

What is the difference between curve of Spee and curve of Wilson?

[1] The curve of Spee is designed to permit protrusive disocclusion of the posterior teeth by the combination of anterior guidance and condylar guidance, and the curve of Wilson also permits lateral mandibular excursions free from posterior interferences.

What is key of occlusion?

The Key to Occlusion has to do with how the Maxillary 1stMolar and the Mandibular 1stMolar come together. In ideal occlusion, the Mesio-Buccal cusp of the Maxillary 1stMolar occludes in the Developmental Groove of the Mandibular 1stMolar. This is known as Class I occlusion. However, not all occlusion is ideal.

What is retromolar gap?

The retromolar triangle, retromolar fossa, retromolar space or retromolar gap is a space at the rear of a mandible, between the back of the last molar and the anterior edge of the ascending ramus where it crosses the alveolar margin.
