Pros Flashcards
main areas of support for upper denture
hard palate
alveolar ridge
maxillary tuberosity
main support for lower denture
buccal shelf
2/3rds pear shaped pad
alveolar ridge
if anterior flange is missing how can this be fixed
addition of greenstick into flange, take impression, ask for rebase
how to fix midline diastema
if all other parts of denture fine - replica denture and at tooth trial ask lab to close diastema
if denture underextended at porosities - how to fix
reline if only problem
remake if other problems
if mandibular tori are present and denture is digging in, how to fix
relieve with soft reline - can be done chair side with self cure acrylic
where should teeth lie on complete dentures
upper - slightly buccal to alveolar ridge
lower - direcetly on alveolar ridge
upper should be more buccal than lower
how to fix a fractured denture
take impression with denture insitu and send to lab
patient has to know will be without denture for couple days - needs to suit patient
what is denture induced stomatitis
poor denture hygiene or ill fitting denture causing inflammation of palate in outline of denture, fungal infection
how is denture induced stomatitis treated
denture hygiene instruction - brush with soft brush after every meal, remove at night time and store in water
keep out as much as possible for now
wash 2x daily in CHX for 10 mins
if medically compromised - prescribe 2% miconazole for topical use
reline denture with coe-comfort, can make new one once resolves
how can angular chelitis come about in denture wearers
reduced OVD if dentures very worn, reduced face height
causing sides of mouth to fold over, moist area allowing bugs to grow
how is angular chelitis treated
occlusal pivots on denture to increase OVD - 1mm a week
prescribe miconazole gel 2% - will work against candida and staph aureus
make new denture once at OVD pt can tolerate
check for anaemia and diabetes
what advantages does CoCr have over acrylic
stronger, can be thinner, less destructive to PDL, better tolerated
what advantages does acrylic have over CoCr
cheap, easy to add to, more aesthetic
when checking for faults in CoCr - what to check for
gaseous porosity - roughness, will collect bacteria and sore on tongue
design - close to gingival margin
sublingual bar instead of lingual bar - will be on FOM, no room for movement
check survey lines, ensure clasps are engaging
check prescription and that it matches
