Question Answer
this extraoral landmark is also known as the wet/dry land because it is the area b/n mucus membrane and lipvermillion border
mandibular/maxillary resorption ratio4:1
where the pink labial mucosa or buccal mucosa meets the redder alveolar mucosa at the mucobuccal fold.vestibular fornix
is there a muscle associated with the labial frenum?nope
what is the muscle associated with buccal frenula?levator labii superioris
mucosa of vestibular spacestratified squamous variably orthokeratinized
features of submucosa in vestibular spacethick, mobile; fibrous connective, high in elastic fibers, adipose tissue
is the tissue in the vestibular space easily displaced or overextended?yep; BOTH easily displaced or overextended
maxillary primary stress bearing areascrest of the residual ridges
mucosa of maxillary crest of ridgemoderately thick, keratinzed
submucosa of maxillary crest of ridgefirm, dense fibrous connective tissue; usually firnly attached to periosteum
what gives primary support to the denture in the maxilla?crest of ridge
what is the most posterior area of the maxilla and can be referred to as mucus mass overlying stress bearing area?maxillary tuberosities
where are the central incisors found in relation to the maxilla?8-10 mm anterior
mucosa of incisive papillastratified squamous
thinner submucosa of incisive papillafibrous connective tissue, nasopalatine canal: VAN, tightly attached to compact bone
what area in the maxilla requires selective relief in the denture?incisive papilla
functions of rugaeinvolve swallowing and improve taste receptors and can be used to identify cadavers
mucosa in ruagekeratinzed
submucosa in rugaedense fibrous connective tissue, adipose tissue, tightly attached to compact bone
what area resists anterior movement of the denture and will rebound if compressedanterior hard palate-rugae zone
does the median palatal suture require relief?yes because it is very thin- MINIMAL RELIEF AND MINIMAL PRESSURE
mucosa of median palatal suture/toruskeratinized, thin
submucosa of median palatal suture/torusminimal submucosa, firmly attached to compact bone
maxillary secondary stress bearing areabuccal and palatal slopes of the ridges
where is the glandular zone?palatal slope and floor of maxilla
this is the junction of moveable and immoveable tissueposterior palatal seal area
what does the posterior palatal seal area cover?it lies on mucosa covering glandular tissue
where is the vibrating line?extends 3mm buccal to one hamular notch
posterior border of posterior palatal seal areavibrating line
anterior border of posterior palatal seal areadetermined by palpation
what are the fovea palatini?remnants of glands in posterior palate
mucosa in posterior hard palateorthokeratinzed stratified squamous
submucosa in posterior hard palatethich fibrous connective tissue, ample salivary tissue
what allows placement of posterior palatal seal area in dentureposterior hard palate-needs to have some degree of displaceability
these are formed at the junction of maxillary tuberosity and junction of spehnoid bonehamular notch
are hamular notches very displaceable?not really
mucosa of hamular notchnon keratinzed, thick
submucosa of hamular notchloose areolar connective tissue, deep tensor veli palatini tendon
this is part of the palatal seal, but won't tolerate deep extensionhamular notch
what is the secondary support zone in the mandible?crest of the ridge
mucosa of mandibular crest of ridgethick, variable, keratin
submucosa of mandibular crest of ridgethick, movable connective tissue, variable attachment to SPONGY bone
this area is parallel to the occlusal plane and has thick, cortical bonebuccal shelf
mandibular primary stress bearing areabuccal shelf
mandibular buccal shelf mucosastratified squamous
submucosa in mandibular buccal shelffibrous connective tissue, overlies dense compact bone, variable attachment, fibers of buccinator run ant./psot
this is the primary support zone of the mandible when presentbuccal shelf
mucosa of retromolar pad orthokeratinized
submucosa of retromolar pad loose, areolar connective tissue
muscles in the pterygomandibular raphe of the retromolar padsuperior constrictor and buccinator muscles
where can the temporal tendon be deep inretromolar pad
what in the mandible can be used for secondary support, but is easily displacedretromolar pad
this connects the hamulus to the retromolar padpterygomandibular raphe
this is found at the distal end of the alveolar sulcusretromylohyoid fossa
what areas tend to be undercut and will retromylohyoid fossa
