Socket Preservation

Question 1

What is the goal of atraumatic tooth extraction?

Answer 1

Extracting the tooth by only cutting the fibers without removing bone

Question 2

What is expected within 24 hours of extraction?

Answer 2

Blood clot

Question 3

What is expected within 1-3 days of extraction?

Answer 3

Fibrinolysis

Question 4

When is granulation tissue expected to replace the coagulum?

Answer 4

2-4 days

Question 5

When is the vascular network expected to form?

Answer 5

1 week

Question 6

T/F: By week 2, the socket should be covered in new connective tissue.

Answer 6

True

Question 7

How long does it take for the new soft tissue to become keratinized?

Answer 7

4-6 weeks

Question 8

T/F: Hard tissue remodeling continues for months after the extraction.

Answer 8

True

Will eventually lose bone

Question 9

T/F: There is more bone resorption in the buccal area of an extraction site.

Answer 9

True

Question 10

How much of the buccal-lingual thickness of the ridge will be lost in the first year after extraction?

Answer 10

5-7 mm

Question 11

T/F: There is roughly half the bone loss is a grafted extraction site.

Answer 11

True

Question 12

Could you do immediate implant placement in a Class I socket?

Answer 12

Yes

Question 13

What causes a socket to be a class II or III?

Answer 13

Dehiscence defects

Question 14

A socket with horizontal defects will be which class? Vertical defects?

Answer 14

Horizontal - class IV
Vertical - class V

Question 15

T/F: Alveolar ridge preservation (ARP) is done to stop bone resorption.

Answer 15

False

Control bone resorption

Question 16

What are the contraindications for ARP?

Answer 16

Infection, immediate placement, soft tissue limitations (fistula)

Question 17

T/F: Osteoconductive grafting materials stimulate the resident cells.

Answer 17

False

conductive - act as scaffold

Inductive - stimulate cells

Question 18

T/F: Autogenous grafts are osteogenic, osteoinductive, and osteoconductive.

Answer 18

True

Holy Grail

Question 19

What properties do allografts have?

Answer 19

Osteoinductive and/or osteoconductive

Question 20

What properties do xenografts have?

Answer 20

Osteoconductive

Question 21

What is the role of the membrane barrier?

Answer 21

Keep good stuff in, keep bad stuff (epithelium) out

Question 22

What are four keys for the outcome of alveolar ridge preservation?

Answer 22

1. Blood supply
2. Space maintenance
3. Membrane stability
4. Tension-free flap closure

Question 23

T/F: Implants should be placed at the same angle of the roots of the adjacent teeth.

Answer 23

False

More upright and slightly lingual

Question 24

What makes side by side implant placement so difficult?

Answer 24

Bone between implants will be lost and the papillary soft tissue will go with it - black triangle
