Waldrop Flashcards
Options to fix a narrow alveolar ridge to prepare
for an implant
narrow platform fixture
Ridge expansion via: guided bone regeneration,
distraction osteogenesis, or split alveolar ridge
What is used in conjunction with Guided bone
regeneration to control the soft tissue bridging of a
defec
e-PFTE membrane
Time for soft tissue healing at extraction site
6-12 weeks
Areas for bone graft materials extra-ora
illium, calvarium, clavicle, tibia, fibula, scapula
Areas for bone graft materials intra-oral
mandibular symphysis, retromolar area, body of
mandible, ramus of mandible
)2 types of resorbable membranes
non-resorbable (e-PTFE)
Resorbable (collagen or synthetic polymers)
Best way to close flap for healing
ension free flap closure with smallest needle and
suture material with mattress holding sutures or
interrupted sutures
What can be used to enhance bone grafts
platelet rich plasma or growth factors
Do you need a surgical template/guide
yes
)4 ways to restore inadequate keratinized tissue for
implant
free gingival graft
Connective tissue graft
Alloderm-acellular dermal graft
Skin graft
do what if have inadequate oral mucosa for
implant
guided tissue expansion
Do what for gingival excess at implant site
esthetic crown lengthening
All platforms/diameters/surgical systems have
what for ease of use
color coding
What bone requires tapered 4.3mm drill
Types 2,3,4
Dense bone drills are used in what bone type
Type 1 & 2
4 things a dense bone drill does for implant
site
dense bone drill is the final bone drill
Removes steps left by tapered drills
Will not oversize the site
Allows passive fit
)When is a dense bone drill used
after the final tapered drill
Must an implant always be placed at the same
level in the bone
No, varies, can be level with crest, slightly above
crest or collar above crest
4 reasons for the variability in depth of implant
limited intra-arch space
Narrow bone bucco-lingual
Esthetics
Increase crown:root ratio
This determines initial stability of the implant and
prevents over tightening the implant
surgical torque wrench
Primary stability with the surgical torque wrent
between ___ and ___ Ncm
35-40 Ncm
What is used in the surgical area and with the
instruments
copious cooled irrigation
What is drill speed for the tapered groovy and
dense bone drills
800 rpm
)What is the drill speed for the straight groovy bone
drills
2000 rpm
What is the rpm/ Ncm for screw tap drilling
25 rpm or 45 Ncm torque
What is the rpm/Ncm for implant placement
25 rpm or 20-45 Ncm torque
What is the final torque with the torque wrench
35-45 Ncm
What motion is used for implant site drilling
in and out with drill in bone for 1-2 seconds
How far does the drill preparation extend beyond
the implant
1mm (must be accounted for in treatment
planning)
which drill type is single use: tapered or straight
Straight
When are tapered drills to be replaced
after 20-30 uses or when cutting efficiency lessen
Heat generated from drill can be transmitted how
far in bone and what does this ultimately result in
> 3mm, implant failure
Do not exceed what temperature when preparing
site
47 deg C
Factors to minimize heat
copious cooled irrigation
Incremental drilling
Intermittent drill pressure
New (sharp) drills
Rule for placing implant
2mm below adjacent CEJ or gingival margin
Rule for bone graft in socket at implant placement
bone graft if space larger than 2mm
2 uses for a surgical guide
implant placement
Index implant for temporary crown
Posterior occlusal tables should be _____to
alleviate lateral occlusal forces
Narrow
Of the 3 flow charts for approaches to treatment,
what was the first consideration before the implant
Site: immediate implant at EXT site
Site: Flap technique
Site: Flapless technique
With the 3 flow charts for approaches to
treatment, after it is determined what the site will be
(e.g. EXT site, flap, flapless), what is asked next
Bone graft or no bone graft
With the 3 flow charts for approaches to
treatment, after it is determined what the site will be
(e.g. EXT site, flap, flapless), what is asked next
Bone graft or no bone graft
With the 3 flow charts for approaches to
treatment after it is determined if the site will require a
bone graft or not, what are the common options in all 3
graphs
)healing abutment or immediate provisionalization
With the 3 flow charts for approaches to
treatment the Immediate placement at EXT site and the
Flap site, when it required a bone graft, what was the
other option besides healing abutment or immediate
provisionalization
2 stage implant
Wit the 3 flow charts for approaches to treatment,
what is the consideration in all of them in the esthetic
zone
connective tissue graft with or without bone graft
