Managing the Extraction Socket Flashcards
bundle bone (3)
histologic term for the portion of the alveolar bone that surrounds teeth and into which the collagen fibers of the PDL are embedded
-alveolar bone proper
-dependent on the tooth
post extraction dimensional changes
-marked dimensional changed during the first 00 weeks
bundle bone is resorbed and replaced with —
more – reduction in buccal bone (more bundle bone)

classification of the extraction socket is based on the
status of the buccal bone and soft tissue
intact buccal bone =
maginal dehiscence = severe dehiscence

patient factors (4)
smoking
oral hygiene
systemic conditions
compliance
atraumatic extraction (4)
diagnostic planing
RCT, restored, or fractured teeth
sectioning teeth
flap or flapless
regeneration (3)
-regeneration of PDL, cementum, and bone (teeth)
-regeneration of (bone) through osteoblasts and exclusion of CT
-requires space maintenance, osteoconduction, and osteoinduction
requirements (3)
stable clot formation
epithelial cell exclusion
graft containment
osteoinductive materials (2)
autograft - local or peripheral sites
allograft - freeze dried bone (cortical/cancellous)
osteoconductive materials (2)
xenogradt (BioOss)
alloplast - ca sulfate, btcp
barrier materials
collagen membrane -resorbable vs nonresorbable
socket presentation adv (3)
-reduce vertical and horizontal dimensional changes
-maintain soft tissue integrity and esthetics
-improve dental implant tx outcome
