OS Q7: sutures

-used to suture
-cutting edge faces

-more "0"s = smaller

-monofilimentous
-easier to tie, very passive
-gone in 3-4 days

-capillary action that pulls fluid and bacteria into body
-important for immunocompromised
-silk whicks

-harder to tie

-to close oral-anthrum (?) perferations

-holds something is socket

-grab at knot
-cut flush with the tissue
-don't pull knot through tissue! You are contaminating the wound

periosteum
submucosa
mucosa

vessels
artery
veins
_______

-full thickness
-

-take same amount of time to heal
-do less iatrogenic damage w/ big flap (better access)

-extend envelope
-drop releasing incision

-base has to be >/= margin (b/c of blood supply)
-go 1-2 teeth away from where you are working b/c you want to replace flap on solid bone, not empty hole (will get infected)

-iatrogenic
-flap not cleaned before replacing
-irrigate flap extensively (under retractor too)
-appears 5 weeks after surgery

-NEVER!!!
-risks GP artery
-instead scallop around teeth

-frequently cut
-not a problem

-BAD!! Don't damage

-can damage w/ retractor

-if section all the way through tooth into lingual plate
-flap design for 3rds
-no releasing incisions on lingual of mandible EVER!!

-okay to sacrifice (same as long buccal)

-put a suture in every papilla violated

-stent for 10 days
-or else gravity pulls flap away from blood supply, impedes healing and promotes infection
-must have in tori area

-reflect M-P flab
-buccal bone removal
-division of crown/roots

-when reg ext fails
-divergent, curved roots
-old RCTed teeth
-hypercementosis
-submerged, ankylosed (often deciduous)
-impacted teeth
-ankylosed teeth
-extensive caries, large restoration
-geriatric pts w/ dense bone
-questionable path of delivery
-root fragment

-when molar is in close prox to sinus
-to preserve the maxillary cuspid eminence

-can be left in mouth if no infection in tooth and extraction will be uneccessarily traumatic
-but if there is infection, must extract!
-xray at 3mo, 6mo

-can flap or no flap depending on how big, how many, etc

-"T" design
-find furcation, cut upward
-then cut central groove
-best to cut from furcation first or else common error to not go deep enough, and crown fractures off

-envelope flap
-remove buccal bone from roots
-cut off buccal roots
-remove crown w/ palatal root intact
-then extract buccal roots individually

-put bur in furcation
-cut up 2/3rds of way
-insert elevator (?), fracture tooth
-this protects lingual plate (lingual nerve)
-document!

-flap
-window in bone on buccal
-tap tooth, it will crack out lingual (?)
-ok b/c far from lingual nerve?
