What are the denture bearing areas?
What are the denture bearing areas?
Those surfaces of the teeth and edentulous ridges covered by a denture.
What are the primary denture support areas on the maxilla and mandible?
Palatal Seal Area Tuberosity Maxilla-Anatomic Landmarks Tuberosity – is an important primary denture support area . It also provides resistance to horizontal movements of the denture. Posterior Palatal Seal Area – Is distal to the junction of the hard and soft palate at the vibrating line . 10.
What is stress bearing area?
Primary stress bearing areas of maxilla are crest of alveolar ridge and the horizontal plate of palatine bone and in the mandible; it is the buccal shelf area. Secondary stress bearing areas of the maxillary foundation are rugae area and the slopes of the ridge in the mandibular foundation.
What is buccal shelf area?
buc·cal shelf (bŭkăl shelf) Broad flat surface of the posterior mandible buccal to the teeth or alveolar ridge that provides denture support.
What is basal seat area?
ba·sal seat ar·e·a that portion of the oral structures available to support a denture.
What is the difference between retention 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.
Why is it called primary stress bearing area?
1. Hard palate: the ultimate support for a maxillary denture is the bone of the hard palate which is formed of two maxillae and the palatine bone. It is considered as primaey stress area because it resist resorption.
What is Retromylohyoid space?
Definition. The space behind and below the mylohyoid ridge. Specifically, the part of the alveolingual sulcus distal to the lingual tuberosity (the distal end of the mylohyoid ridge). retromylohyoid space.
What is basal seat of denture?
Tissues in the mouth that support a denture.
What is RRR in dentistry?
RRR is basically a term used to describe a condition that affects the alveolar ridge after tooth extractions even after healing of the wounds. RRR is a chronic, progressive, irreversible, and disabling disease, probably of multifactorial origin.
What is Interarch space?
: The interarch space is defined as the vertical space between the edentulous ridge and the occlusal or incisal aspect of the opposing arch. Measuring the interarch space in a patient requiring an implant-supported fixed prosthesis is crucial for determining the prostheses to be used in each clinical situation.
What is Retromolar area?
The retromolar space or retromolar gap is a space at the rear of the mandible, between the back of the last molar and the anterior edge of the ascending ramus where it crosses the alveolar margin.
What is Hamular notch?
Hamular notch means the area behind the upper back molar.
What is impression compound?
Impression compound is a mucocompressive, thermoplastic (i.e., it softens when heated and hardens when cooled) and rigid impression material that was invented by British dentist Charles. T. Stent in 1856.
What is secondary impression?
1. a slight indentation or depression, as one produced in the surface of one organ by pressure exerted by another. 2. a negative imprint of an object made in some plastic material that later solidifies. 3.
What is interdental space?
The interproximal, or interdental, area is the space that lies between teeth that is occupied by the gum.
