What is a rest seat denture?
Any component of a partial denture on a tooth surface that provides vertical support is called a rest (Figure 6-1). Rests should always be located on properly prepared tooth surfaces. The prepared surface of an abutment to receive the rest is called the rest seat.
Why the occlusal rest should be prepared that direct the occlusal force along the long axis of the abutment?
The relationship between a rest and a rest seat must be such that forces transmitted from the prosthesis to an abutment are directed apically down the long axis of the tooth. In this manner, stress can be absorbed by the fibers of the periodontal ligament without damaging the ligament or the supporting bone.
What is the purpose of taking the bite and occlusal registrations for partial dentures?
Taking a jaw registration has been found to facilitate the achievement of optimum occlusal and mucosal support, as well as minimising clinical and technical errors in partial dentures.
What is the function of a rest on a partial denture quizlet?
Rest prevents the partial denture from moving gingival direction, aids in distributing the retention load the several T, and prevents food from getting between the abutment and retainer.
Which factor enhances retention of a removable denture?
Physical forces influencing denture retention are believed to include adhesion, cohesion, capillary attraction, surface tension, fluid viscosity, atmospheric pressure, and external forces imparted to the prostheses by oral-facial musculature.
Can you brush partial dentures?
You’ll need to brush your partial dentures every day to remove plaque and help prevent stains on the false teeth. It’s best to use a brush that is designed for cleaning dentures.
How does a removable partial denture receives its support and retention?
How does a removable partial denture receive its support and retention? It prevents the partial denture from moving in a gingival direction. It aids in distributing the retention load to several teeth. It prevents food from getting between the abutment tooth and the retainer.
How does a removable partial denture receive support and retention?
Some of the occlusal force distributed from artificial teeth is transferred to the edentulous ridge directly through the denture base. Since there is some surface adhesion and friction between the denture base and oral mucosa, this assists the retention and stability of partial dentures.
What is indirect retainer in prosthodontics?
An indirect retainer consists of a minor connector and a rest, and helps to stabilize the distal extension RPD, indirectly (compared to direct retention with clasps), when the patient eats sticky foods. Most frequently, indirect retainers are placed on canines or the mesial fossa of first premolars.
