|
One-fourth to one-seventh
|
|
|
4. As demonstrated by a number of studies, what is the percentage of pts that are fully satisfied with their dentures?
|
70%
|
|
|
Factors which impact dentures
|
nature of bearing mucosa
bone contours and retromolar pad muscle attachments saliva disease factors |
|
|
Frenum
|
affects retention-frenctomy
|
|
|
Buccal vestibule
|
stability and retention
|
|
|
canine eminence
|
support and stability
|
|
|
incisive papilla
|
denture relieved over area
|
|
|
tuberosity
|
primary support area
resistance to horizontal movements |
|
|
rugae
|
resist anterior displacement
2ndary support |
|
|
Hamular notch
|
retention/sorenss
|
|
|
coronoid process
|
width of distobuccal flange will be contoured to coronoid process
|
|
|
fovea palatina
|
2, posterior to jxn of soft/hard
|
|
|
Minor salivary glands
|
posterior 1/3 of hard palate
|
|
|
zygomatic-alveolar crest
|
thin mucosa not good for stress
|
|
|
hard palate
|
horzontal palatine processes
primary support area |
|
|
midline palatal suture
|
releif needed
|
|
|
major palatine foramen
|
releif need, due to blood and nerve
|
|
|
ideal max ridge
|
keratinzed
square u-cross section medium palatal vault no undercuts frenum distal from crestal ridges well defined hamular notces |
|
|
mentalis
|
dictates length and thickness of labial flange
|
|
|
alveolar ridge type of support area
|
2ndary support
|
|
|
buccal shelf type of support
|
primary-need more access, determined by buccinator muscle
resorption can make b.shelf smaller |
|
|
external oblique line
|
lateral termination of buccal flange
|
|
|
mental foramen
|
relieved
|
|
|
retromolar pad type of support
|
primary
|
|
|
masseter groove fxn?
|
masseter muscle reflects buccinator muscle in superior medial direction, must allow freedom of this action(DB flange)
|
|
|
mylohyoid forms?
|
muscular floor of mouth
|
|
|
mylhyoid ridge
|
undercut
|
|
|
geniotubercle attachment?
|
attachment for genioglossus and geniohyoid...relieve
|
|
|
mylohyoid muscle sig?
|
floor of mouth
|
|
|
lingual frenum + sublingual folds
|
LF: overlies genioglossus muscle
SF: sublingual glands and ducts of sm glands |
|
|
retromylohyoid space
|
stability and retention
|
|
|
modiolus
|
later and superior to corner of mouth
where extrinsic perioral muscles join intrinsic fibers of orbicularis oris |
|
|
Buccinator
|
fibers contract in a line parallel to the plane of occlusion..age reduces this tension
|
|
|
mentalis
|
labial flange extenion
|
|
|
Orbicularis Oris
|
sphincter muscle of mouth
|
|
|
soft palate class
|
Class 1 best-->3
1 least movement to close |
