Managing the Extraction Socket

Question 1

bundle bone (3)

Answer 1

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

Question 2

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)

Answer 2

8
woven bone
vertical

Question 3

on avg in 6 months
avg vertical bone loss:
avg width bone loss:

Answer 3

1.2-1.7 mm
3.7-3.9 mm

Question 4

classification of the extraction socket is based on the

Answer 4

status of the buccal bone and soft tissue

Question 5

intact buccal bone =

Answer 5

maginal dehiscence = severe dehiscence

Question 6

type of socket affects

Answer 6

our tx approach

Question 7

at 6-12 mo post extraction
avg VBL:
avg wifth bone loss:
most changes during

Answer 7

1.5-2 mm
40-50%
first 3 mo

Question 8

patient factors (4)

Answer 8

smoking
oral hygiene
systemic conditions
compliance

Question 9

atraumatic extraction (4)

Answer 9

diagnostic planing
RCT, restored, or fractured teeth
sectioning teeth
flap or flapless

Question 10

regeneration (3)

Answer 10

-regeneration of PDL, cementum, and bone (teeth)
-regeneration of (bone) through osteoblasts and exclusion of CT
-requires space maintenance, osteoconduction, and osteoinduction

Question 11

requirements (3)

Answer 11

stable clot formation
epithelial cell exclusion
graft containment

Question 12

osteoinductive materials (2)

Answer 12

autograft - local or peripheral sites
allograft - freeze dried bone (cortical/cancellous)

Question 13

osteoconductive materials (2)

Answer 13

xenogradt (BioOss)
alloplast - ca sulfate, btcp

Question 14

barrier materials

Answer 14

collagen membrane -resorbable vs nonresorbable

Question 15

socket presentation adv (3)

Answer 15

-reduce vertical and horizontal dimensional changes
-maintain soft tissue integrity and esthetics
-improve dental implant tx outcome

Question 16

socket presentation disadv (3)

Answer 16

-increase tx time and costs
-technique sensitive/surgical factors
-usage of regenerative materials

Question 17

immediate implant placement

Answer 17

placement of the dental implant immediately into a fresh extraction socket

Question 18

type 1

Answer 18

immediate placement

Question 19

type 2

Answer 19

3-8 weeks
early implant (soft tissue healing)

Question 20

type 3

Answer 20

3-4 mo
early implant (partial healing)

Question 21

type 4

Answer 21

6 mo
late implant (complete healing)

Question 22

immediate implant placement indications
(5)

Answer 22

presence of 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
reduce tx time

Question 23

surgical planning:

Answer 23

proper position= restorative driven

Question 24

post op management (5)

Answer 24

abx (amoxicillin 500 mg or clindamycin 300 mg)
0.12% chlorhexidine gluconate rinse
medrol dose pack
NSAID 600-800 mg ibuprofen
narcotics

Question 25

post of timeline suture removal: update home care and diet instructions new radiographs: total healing time:

Answer 25

2 weeks 6-8 weeks and at day of uncovery or impression taking 3-6 mo depending on integrity of extraction socket and primary stability of immediate implant at time of surgery

Question 26

proper understandning of -- to improve tx outcome

Answer 26

extraction socket

Question 27

(2) are most critical considerations fo immediate implant placement

Answer 27

bone quality and quantity

Question 28

immediate implant placement in the anterior region requires

Answer 28

esthetic work up

Question 29

orientation of the implant should be

Answer 29

restoratively driven
