What is bracing in dentures?
2a and b — Bracing. The horizontal forces are resisted by placing rigid components of the denture (bracing components) against suitable vertical surfaces on the teeth and residual ridges. Parts of a denture resting against the stippled areas will resist the forces whose directions are shown by the arrows.
What is bracing in RPD?
4 — Bracing. Those components of the RPD coloured blue are capable of resisting. lateral forces coming from the direction indicated by the arrows. Needless to say, lateral forces in the opposite direction will be. resisted by the mirror images of these components.
What is retainer in partial denture?
Direct retainers are flexible parts of the casting that are designed to engage undercuts on the abutment teeth to resist removal of the prosthesis and to help prevent dislodgement.
Where should retentive arms be placed?
Reciprocal elements of the clasp assembly should be located at the junction of the gingival and middle thirds of the crowns of abutment teeth. The terminal end of the retentive arm is optimally placed in the gingival third of the crown (Figures 7-4 through 7-6).
Are dentures and braces the same?
Whilst both braces and dentures share the ultimate goal of giving you a great smile, they achieve this in very different ways. Dentures are typically used to replace missing teeth whilst braces help to straighten out your existing teeth, usually without the need for removing any teeth at all.
What is bracing and reciprocation?
The horizontal forces are resisted by placing rigid components of the denture (bracing components) against suitable vertical surfaces on the teeth and residual ridges. Parts of a denture resting against the stippled areas will resist the forces whose directions are shown by the arrows.
What is cross arch stabilization?
The denture design method most commonly used is cross arch stabilization which involves creating a retainer on the side opposite the defect via a bar in order to stabilize the denture and protect the retaining teeth. Almost all research on this method involves experiments using a static load.
What does a retainer do?
Constant use of retainers ensures that the teeth don’t shift or crowd due to lack of space. The teeth will start moving back to their old position in the months following the removal of braces. A retainer can prevent the reversal.
What is clasp assembly?
A CLASP ASSEMBLY is the part of an RPD that acts as a direct retainer and/or stabilizer for the prosthesis by partially encompassing or contacting an abutment tooth. Most RPDs utilize clasp assemblies as direct retainers.
What is the function of a rest on a partial denture?
Thus rests serve to support the position of a partial denture and to resist movement toward the tissue. They serve to transmit vertical forces to the abutment teeth and to direct those forces along the long axes of the teeth.
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.
