1

All are indications for perio surgery except?

To remove epithelial tissue from inner wall of perio pocket

2

Indications for perio surgery

Provide access for improved perio instrumentation of root surfaces
Reduce pocket depths
Provide access to perio osseous defects
Respect or remove tissue
Regenerate the periodontium lost due to disease
Graft bone or bone stimulating materials into osseous defects
Improve the appearance of the periodontium
Enhance prosthetic dental care
Allow placement of a dental implant

3

Common contraindications for perio surgery

Pts who have certain systemic diseases or conditions
Pts who are totally noncompliant with self care
Pts who have a high risk for dental caries
Pts who have totally unrealistic expectations for surgical outcomes

4

Can you do surgery on a pt who is on dialysis?

NO

5

Can you do surgery on a pt with seizures?

YES

6

What is the goal of perio surgery?

For long junctional epithelium to form

7

Should all pts receive non surgical therapy along with surgical therapy?

YES

8

Bone take from pts own body

Autograft

9

Bone taken from another human

Allograft

10

Bone taken from another species

Xenograft

11

Synthetic bone like material

Alloplast

12

How soon should you probe a bone graft site?

When dr says

13

How long do you leave a bone graft undisturbed?

Months or until dr says

14

Before surgery you should always..

Inform pt of changes that they may not like

15

Postsurgically you should...

Expect Swelling
Take medications as prescribed
Take it easy for several days
Eat soft foods
No hot beverages
Don’t chew on surgical site
Rinse with recommended mouth rinse

16

Healing of a wound by formation of tissues that do not precisely restore the original architecture or original function of the body part

Repair

17

What is an example of healing by repair?

The formation of a scar during the healing of an accidental cut finger

18

Healing of a periodontal wound by the reunion of the connective tissue and roots where these two tissues have been separated by incision or injury but not by disease

Reattachment

19

The union of a pathologically exposed root with connective tissue or epithelium

New attachment

20

Biological process by which the architecture and function of lost tissue is completely restored

Regeneration

21

For healing of the periodontium to be described as ________ the healing would have to result in the formation of lost cementum, lost periodontal ligament, and lost alveolar bone

Regeneration

22

A procedure in which incisions are made in the gingiva or mucosa to allow for separation of the surface tissues (epithelium and connective tissue) from the underlying tooth roots and underlying alveolar bone

Periodontal flap

23

A full thickness flap is elevated with what is generally referred to as a

Blunt dissection

24

What is a full thickness flap also called?

Mucoperiosteal flap

25

Involves elevation of entire thickness of the soft tissue

Full thickness flap

26

What is a partial thickness flap also called?

Split thickness flap

27

Includes elevation of only the epithelium and a thin layer of the underlying connective tissue

Partial thickness flap

28

A partial thickness flap is elevated with

Sharp dissection

29

A flap that is sutured with the margin of the flap at its original position in relationship to the CEJ on the tooth

Nondisplaced flap

30

A flap that is sutured with the margin of the flap placed at a position other than its original position in relationship to the CEJ of the tooth

Displaced flap

31

Which type of healing is expected from flap for access surgery?

Healing by repair and usually involved formation of a long junctional epithelium

32

Removal of some tooth supporting bone

Osectomy

33

Reshaping of the surface bone contours

Osteoplasty

34

During surgery to minimize periodontal pockets, it is common for the gingival margin to be positioned..

At a more apical level to the CEJ than originally occupied

35

What does the more apical positioning of the gingival margin result in?

Exposure of a portion of the root to the oral cavity

36

New bone cells and new bone that forms following bone grafting

Osteogenesis

37

A periodontal surgical procedure employed to encourage regeneration of lost periodontal structures (to regrow lost cementum, lost PDL, lost alveolar bone)

Guided tissue regeneration

38

What might be placed under a periodontal flap at the time of surgery to delay the ingrowth of unwanted types of cells into the healing of the wound?

A barrier membrane

39

A type of periodontal plastic surgery that was one of the first procedures to augment the width of attached gingiva

Free gingival graft

40

What does the donor tissue for a free gingival graft include?

Surface epithelium and some of the underlying connective tissue

41

Results in excellent esthetics since the color of the healed tissue often mimics the natural pre existing tissue color precisely what

Subepithelial connective tissue graft

42

Plastic surgery designed to create a longer clinical crown for a tooth by removing some of the gingiva and usually by removing some alveolar bone from the necks of the teeth

Crown lengthening surgery

43

A surgical procedure designed to excise and remove some of the gingival tissue

Gingivectomy

44

Are dental implants surrounded by cementum and periodontal ligament?

No

45

Are implants subject to periodontal disease that can result in the loss of supporting bone just like a natural tooth?

YES

46

How long should you wait to remove sutures?

After 1 week of healing

47

How long can most absorbable sutured be left in place?

1-3 weeks

48

Dressing should be what?

Minimal!
