Q

How does gingival inflammation enter the alveolar bone?

A

1) It extends along the collagen fiber bundles
2) Follows the course of the blood vessels

Q

Bone loss due to periodontal disease is caused by what?

A

Loss of physiologic bone equilibrium

Bone loss in perio disease occurs when destruction overtakes formation

Q

F2

A

In the concavity - in this furcation, we try to do regenerative surgery

17
Q

F3

A

Through and through

At this point it is too late to do surgery

18
Q

What is the goal of treatment with Horizontal Bone Loss?

A

Pocket reduction

Correct reverse architecture

19
Q

What are the treatment options for Horizontal Bone loss?

A

SRP
Gingivectomy
Open flap debridement
Osseous surgery

20
Q

What are the treatment goals with Angular bone loss?

A

Pocket reduction

Restoration of attachment

21
Q

What are the treatment options for Angular bone loss?

A

Osseous Surgery

Guided Tissue Regeneration

22
Q

What are the treatment goals of Furcation defects?

A

Eliminate furcation defects

Provide self-cleaning area

23
Q

What are the treatment options of Furcation defects?

A

SRP
Open Flap Debridement
Osseous Surgery
Guided Tissue Regeneration

24
Q

What type of flap is used with Osseous Surgery?

A

Full thickness

Apically positioned

25
Q

What type of flap is used with Regenerative Surgery?

A

Full thickness

Coronally positioned

26
Q

What type of incision is used with Osseous Surgery?

A
Generally scalloped (but sulcular is used if keratinized tissue is limited)
Additional incisions can be made if needed to apically position
27
Q

What type of incision is used with Regenerative Surgery?

A

Sulcular

Additional vertical incisions can be used if needed to coronally position
