Camargo 2.18.15 Flashcards
TF
periodontal regeneration is more complex than bone regeneration around an implant
true
bc growing an organ around the implant
reconstruction o the periodontal unit [alveolar bone, PDL, and cementum]
- bone graft and bone substitutes
- guided tissue regeneration
3.
new CT attachment
new CT on a root surface that has been
previously deprived of its PDL
instead of periodontal regeneration you can have bone fill
true
waht is bone fill?
clinicall restoration of bone in a previously treated periodontal defect [does not
Periodontal regeneration can ONLY BE DONE with ______ bone loss
vertical bone losss ONLY
when you cant solve the pocket problem that the patient has and you cant fix it through repair and resection you do periodontal regeneration
TF
true
TF
resection is appropriate for advanced periodontal destruction
false
NOT APPROPRIATE
waht are the 4 indications of vertical bone loss?
deep vertical defects
aggressive periodontitis [LKP} defects
anatomical limitations
esthetic areas
furction invasions
of the 5 which one is the most common vertical bone loss ?
deep vertical defects
furcation invasion _____ mm horizontal component
greater than or equal to 4 mm
cortical bone is _____ and if you need blood supply for periodontal regneration and instead of hte PDL adj from taht area and the flap we get it from _____
avascular
use high speed bur and decortication and series of perforation until you reach cancellous bone to enhance blood supply
when you use a bone graft we do NOT –_____ and if you with material you wont get _____ and go to the level of the exisitng bony levels
overfill
primary closure
with an open wound ______ washes away and an ____ chance of infection
material
increased chance of infection
autographs
extra oral [hip bone extraction] and has to be in the surgery room
- not used anymore
TF
true
true
allografts
are material from the ___ species taht come from ____
same
cadavers
the two types of allografts
freeze- dried bone
decalcified freeze-dried boen
xenografts
comes frm a _____ species and the mineral material is very similar to human _____ bone
different
cancellous
TF
xenograft bovine - dervied prous bone material will be absored very slowly
true
slowly and may not be compltely resorbed ever
if the material was demineralized like allograft will DISAPPEAR COMPLTELY
TF
true
\
choice of osseous graft material is not the most important what is most imporant?
clearing the root surface of calculus
when you do periodontal regernation the incision is always in the ____
sulcus
TF
you should completely fill the defect with bone graft in clincial cases
false
filling 60 - 70 % of defect so room for partial success and a case for failure
TRUE new periodntal generation attachment can be done with just bone graft but is ______
unlikely
