Managing the Extraction Socket Flashcards
histologic term for the portion of the alveolar bone that surround the teeth and into which the collagen fibers of the PDL are embedded
bundle bone
which bone replaces the bundle bone?
woven bone
t/f: there is more vertical reduction in the buccal bone because it possesses more bundle bone
true
on an average of 6 months,
avg width bone loss is ______
3.7 to 3.9 mm `
on an average of 6 months,
avg. vertical bone loss:______
1.2mm-1.7mm
t/f: 6-12 months post extraction:
avg. vertical bone loss is 1.5-2 mm
avg width of bone loss is 40-50%
most change during the first 3 months
true
What are the four classifications of sagittal root position?
buccal
middle
palatal
resorbed bone at the root apex
t/f: when regeneratiing bone, keeping connective tissue out of the socket prevents the development of granulation tissue
true
which materials stimulate osteoprogenitor cells into osteoblast and create new bone?
osteoinductive materials
What are the two types of osteoinductive materials?
autograft- from pt
allograft- from cadaver
Which graft materials act as a scaffold for new bone growth from native osteoblasts, and use the graft material to spread the new bone material.
osteoconductive materials
What are the two osteoconductive materials?
xenograft- bovine
alloplast- synthetic
socket presentation advantages:
reduce vertical and horizontal dimensional changes
maintain soft tissue integrity and esthetics
improve dental implant treatment outcome
socket presentation disadvantages
increase treatment time and costs
technique sensitive/ surgical factors
usage of regenerative materials
Timing of Dental Implant placement post-extraction:
Which type is this?
immediate implant placement
type 1
Timing of Dental Implant placement post-extraction:
Which type is this?
4-8 weeks- soft tissue healing
type II
Timing of Dental Implant placement post-extraction:
Which type is this?
3-4 months partial bone healing
type III
Timing of Dental Implant placement post-extraction:
Which type is this?
6 months
complete healing - late implant
type IV
When is immediate implant placement indicated?
- adequate presence of the buccal plate
- soft tissue may/may not be intact
- adequate alveolar bone in the palatal aspect of extraction socket for primary stability of the implant
- esthetic considerations
- reduced treatment time
WHat are the post-operative management steps taken?
- antibiotics (amoxicillin 500 mg or clindamycin 300 mg
- 0.12% chlorohexidiene gluconate rinse
- medrol dose pack
- NSAID (600-800 mg ibuprofen)
- narcotics
when are sutures removed?
2 weeks
t/f; take new radiographs at 6-8 weeks and the day of uncovery or impression taking
true
What is the typical healing timeline depending on the integrity of extraction socket and primary stabiility of immediate implant at time of surgery
3-6 months
