11/5 Implant Overdenture pt. 3 Flashcards
nobel biocare are
bone level only
if measured 1 mm all the way around with a little 1.5 order what
1
want as close to free gingival margin as possible
tissue level implants are usually
one stage surgery
sites ABOVE the free gingival margin
needs NO trans-gingival measurment for the abutment
T/F in tissue level you need cuff height / trans gingival measurements
YES some might
T/F bone level implant can project out of gingiva / tissue
yes it can but shouldnt necessarily happen
T/F bone level implant can project out of gingiva / tissue
yes it can but shouldnt necessarily happen
locator had a tapered profile?
maybe the implant was suppse to be more submerged
so margin of retention was suppose to be at FGM
please make EXTREME CAUTION WHEN MEASURING ____
when measuring so you DO NOT add any additional height to a bone level abutment

only order the tissue cuff height that you …
MEASURE!
rule #3
the more RESILIENT the attachment the more you must rely on the RIDGE ANDTISSSUE for SUPPORT
non resilient attachments
100% implant borne
impression of soft tissue is irrelevent
dependent on the accurate impression of the implant fixture
examples - fixed and fixed detachable
hybrid
a nonspecific term applied to any prosthesis that does not follow a conventional design frequently used to describe a dental prosthesis that is compromised of different materials
usually like combo of denture and fixed restortaitons
fixed element of hybrid
porcelain or zirconia
both teeth and tissue POSSIBLE iwht porcelain
BUT ARCYLIC OR COMPOSITE resin recommended
metal part of a hybrid?
Yes –
restricted vertical resilient in
a dolder bar unit
95% implant born
5% tissue
need a minmum of 4-6 fixtures (max - mand) to prevent torquing
minimum fixed in a dolder bar
4-6 fixtures to prevent torquing
hinge resiliency is usually
a hader bar joint
hader bar joint
35% implant borne
65% tissue / ridge
2-4 fixtures
nylon patrix provides great resiliency
dolder bar joint
EGG SHAPED
50% IMPLANT BONE - 50% TISSUE
4 fixtures
is restriced vertical resilient only if mulitple bars
dolder bar joint is resitricted vertical resilient?
yes but only if multiple bars are used
dolder bar joint is resitricted vertical resilient?
yes but only if multiple bars are used
space analysis of bar
prosthesis size and what is going on underneath it
neutral zone has to fit all of this
esthetic space is
space between the ridge crest and the correspoonding lips at repose
removable vs those with attachments in terms of estehtic space
removable restoration supported by individual attachments will require less esthetic space than those supported by a bar
basic needs for cross arch stabilizaton
bars to resist lateral loads
bars to improve stability of the prosthesis
