classification of mucosa that is EXCESSIVELY DISPLACABLE and possibly requires. surgical corrrection

epulis fissuratum

folds of hyperplastic tissue in the edentulous ridge caused by chronic irritation from dentures.

inflammatory papillary hyperplasia

multiple papillary projections of inflammatory tissue on the palate, often associated with ill-fitting dentures or poor hygiene

Retrognathic

a dental condition characterized by the mandibular arch positioned extensively LINGUAL to maxillary arch, potentially affecting occlusion and denture fit

prognathic

a dental condition characterized by the mandibular arch positioned LABIAL to maxillary arch, potentially affecting occlusion and denture fit

supeiror pharyngeal constrictor

the distal extension of the lingual flange of mandibular denture is limited primarily by the _____ muscle

posterior to vibrating line

where are the fovea palatine most commonly located

true

T/F The incisive papilla is the exiting point of the nasopalatine nerves and vessels, and may require relief in the finished denture base

true

T/F The retromolar pad is a landmark that can be used to determine the occlusal surface of the lower posterior teeth.

true

T/F The hamular notch is a soft area of areolar tissue between the distal surface of the tuberosity and the hamulus; it houses the distolateral termination of the denture base

retention

the ability of a denture to resist movement away from the underlying tissues during function

stability

The ability of a denture to maintain its position and resist LATERAL movement during function
