thickness of minor RPD connectors - 1.5 mm
Minimum space between vertical components of RPD - 5 mm
Kennedy Class I - bilateral distal extension
Kennedy Class II - unilateral distal extension
Kennedy Class III - entirely tooth born with teeth anterior and posterior
Kennedy Class IV - edentulous area anterior to remaining teeth
Lingual bar distance from gingival margin - 3 mm
Lingual bar width (minimum) - 4 mm
Maxillary major connectors, how far from gingival margin - 6 mm
Max RPD bead line width and depth - .75-1 mm
Anterior-posterior palatal strap, minimum distance between straps and minimum width for
each strap - 15 mm between, 6 mm anterior and 8 mm posterior
Palatal plate advised when? - The last abutment on either side is a canine or premolar
Main function of indirect retainers - prevents vertical dislodgement of the distal
extension base away from tissues (sticky food)
Minimum number of rests for RPD - 3
For a distal extension where is the rest on the most posterior tooth - mesial
rest seat depth - 1.5 mm at marginal ridge and 2 mm in center, at least 2.5 mm wide
,what is prepared first? Guide planes or seats - guide planes
extended occlusal rests used when? - used when most posterior molar abutment is
mesially tipped in class II (mod I) and class III
Cingulum rest depths - 2 mm wide (F-L), 2.5-3 mm (M-D), 1.5 mm deep
Guide plane position relative to height of contour for classes of RPD - Class III and IV can
end above the height of contour because there is no functional movement. Class I and II must
be below the height of contour (to prevent torquing). With I-bars and mesial rests on premolars,
must end exactly at the height of contour.
how to determine number of clasps - kennedy classification + 1 (except for class IV)
Undercut of 0.01 - cast clasp
Undercut of 0.02 - wrought wire (0.5 mm and must be at least 8 mm long, 18 gauge)
chromium provides what - corrosion resistance
cobalt provides what - rigidity
Nickel provides what - ductility
What muscle dictates the DB of the mand flange of a denture - masseter
What muscle dictates the DL of the mand flange of a denture - superior constrictor
muscle
how far to trim back the custom tray from the mucosal reflection - 2 mm
occlusion rim heights - maxillary 22 mm, mandibular 18 mm
The inferior surface of the maxillary occlusal rim should be parallel to... - Camper's Line
(Ala-tragus Line) and inter-pupillary line
primary and secondary support for mand denture - primary - buccal shelf, secondary -
alveolar ridge
Posterior palatal seal - extends through the hamular notches, 2 mm in front of fovea
palatinae, carried 5 mm anterior to the vibrating line
if denture falls down when smiling - buccal notch and buccal flange are excessively thick
Golden Proportion Ratio - 1.6:1:0.6 (central:lateral:canine)
,S sounds like "th" - either max anteriors are too far palatal or palate is too thick. S sounds
bring the max and mand closest together (than other sounds)
Occlusal clearance gold - 1.5 mm functional, 1 mm non-functional
Occlusal clearance PFM - 1.5-2 mm functional, 1-1.5 non-functional
all ceramic clearance - 2 mm
Percentages for PFM copings - high noble (98% gold, platinum and palladium - these
metals do not oxidize on casting), Noble (50-60% palladium, 30-40% silver - silver will oxidize),
Base (70-80% nickle, 15% chromium - these both oxidize on casting)
Coping thickness - noble metal is 0.3-0.5, base as thin as 0.2
Implant overdenture minimum space - locator - 8.5 mm, ball and o-ring - 10-12 mm, bar
clip - 13-14 mm
Polysulfide impression material - rubber base, setting time of 12-14 min
PVS - poured up to 1 week, hydrophobic, do not wear latex gloves, 6-8 min setting time,
temperature sensitive (sets faster in heat)
polyether - impregnum, hydrophillic4-6 min setting time, most stiff,
gypsum made of? types? - calcium sulfate hemihydrate; type I - rarely used, plaster of
paris, type II - ortho casts, not very strong, type III - dentures, type IV - use for stone dies, type V
- stone dies, most popular today
PDL types of elastin - No mature elastin, 2 types of immature: oxytalan (regulates
vascular flow, parallel to root surface) and eluanin
attached gingiva - narrowest bands - buccal mand canines and 1st premolars, lingual
mand incisors and canines
Junctional epithelium - 2 basal laminas (internal faces the tooth) and external (faces the
connective tissue)
Proliferative cell layer - responsible for most cell divisions and located next to external basal
lamina
long junctional epithelium - refers to junctional epithelium in disease, as JE gets longer
and moves apically the coronal portion detaches
, ANUG (acute necrotizing ulcerative gingivitis) - treponema denticola (spirochete),
predominately neutrophils involved
First cells involved in acute inflammation (start of gingivitis) - Polymorphonuclear
neutrophils (PMNs)
Acute inflammation - vascular phase (mast cells, basophils and platelets release
histamine) and cellular phase (PMNs, then eventually macrophages)
main cell components of chronic inflammation - polymorphonuclear leukocytes (PMLs)
pregnancy gingivitis has increased levels of - prevotella intermedia
Generalized Aggressive Periodontitis - At least *3* permanent teeth other than the *1st
molar* and *incisors* are involved
Localized aggressive periodontitis - -Disease that begins at age 11 to 13 with strong
familial tendency
- attachment loss at first molars and incisors
- AA bacteria
Hyperthyroidism - Graves disease - most common, goiter and exopthalmos
Plummer's disease - multiple adenomas of the thyroid gland, exopthalmos is rare
Hypothyroidism - myxedema - puffiness of face and eyelids, swelling of tongue and larynx
cretinism - in a child, severe mental retardation, large tongue, under-developed mandible, over-
developed maxilla, delayed teeth eruption and deciduous teeth retained longer
hyperparathyroidism - common complaint of kidney stones; osteoporosis and giant cell
granulomas, usually caused by adenoma but could occur if there is excessive loss of calcium in
the urine (parathyroid will increase in size to compensate)
Clinically - cystic bone lesions(Recklinghausen's)
Hypoparathyroidism - usually due to accidental excision during thyroidectomy, congenital
(DiGeorge's syndrome)
Pituitary diseases - excess (from adenoma) - acromegaly (giganitism if before growth
plates fuse)
too little - achondroplasia (dwarfism)
