23
Q

How much bone should you have buccal to the implant?

A

2mm

24
Q

T/F: The oval shape of the sockets is beneficial for immediate implant placement.

A

False

Implants are circle so hard to prevent gaps

25
Q

T/F: Full thickness flap is necessary for implant placement.

A

True

26
Q

What is a two-stage implant placement procedure?

A

Cover implant and uncover it to place healing abutment after osseointegration phase

27
Q

How long does osseointegration take for maxilla and mandible?

A

3 months for mandible

6 months for maxilla

28
Q

What is the most common way to place implants?

A

Use two piece implant with one stage procedure

Place implant and healing abutment together without closing

29
Q

T/F: Bone level implants must be submerged all the way into the bone.

A

True

Do not want rough surface exposed in tissue

30
Q

T/F: Cover screws are flat and are used during one-stage placement of implants.

A

False

Cover screws are flat but used in two-stage

31
Q

What are three contraindications for one-stage placement?

A
  1. Less than ideal primary stability
  2. Smokers!
  3. Thin tissue biotype
32
Q

T/F: All perio problems should be solved prior to implant surgery.

A

True

33
Q

How apical to the CEJ of adjacent teeth should the implant shoulder be placed?

A

2 mm

34
Q

When are the first two post-op visits?

A

7-10 days - check for infection

1 month - if two-stage, make sure it is still covered

35
Q

What is a stent?

A

Surgical guide

36
Q

What is the amount of space between the shoulder and contact point that will avoid black triangles?

A

5 mm

37
Q

T/F: Articulated casts are necessary for making a stent.

A

True

38
Q

T/F: Vertical and inter-implant papillae bone augmentation are predictable surgeries.

A

False

Lateral is good

39
Q

What is a hybrid?

A

Fixed implant supported denture

40
Q

What is an overdenture?

A

Implant supported denture

41
Q

What is the best way to diagnose peri-implantitis?

A

Serial radiographs

42
Q

T/F: There will be some bone loss after loading of the implant.

A

True

Not peri-implantitis

43
Q

What are some diagnostic findings of peri-implant infections?

A
  1. BoP
  2. Suppuration
  3. Probe depths
  4. Mobility
  5. Radiographic bone loss
44
Q

T/F: There are methods to save a mobile implant.

A

False

It has failed

45
Q

Can an implant with no function have peri-implantitis?

A

NO

If an implant fails before loading it never fully integrated - NOT peri-imlantitis

46
Q

What is peri-implant mucositis?

A

Reversible inflammation in soft tissue around an implant

47
Q

What is the treatment plan for a patient with an implant probe depth of less than 4 mm and no BoP or plaque?

A

Do nothing

48
Q

What are the best treatment options for failing implants?

A
  1. Resolve inflammation
  2. Recontour gingiva (reduce pocket)
  3. Re-osseointegration
49
Q

What is re-osseointegration?

A

Decontaminate the implant surface with citric acid or tetracycline and try GBR around it

50
Q

When the vertical bone loss becomes circumferential around the entire implant, what class of peri-implantitis is this?

A

Class 3

51
Q

Is GBR needed for Class 2 peri-implantitis?

A

Depends on if there are any localized vertical defects

52
Q

What is imantoplasty?

A

Removing the grooves from the exposed implant surface

53
Q

What is infuse?

A

A collagen sponge mixed with bone growth proteins placed under the packed bone to help infuse bone growth

54
Q

T/F: Patients with implants must get at least 2 visits a year.

A

True

55
Q

What is the furthest possible apical placement for the shoulder of the implant compared to the CEJ of adjacent tooth?

A

5 mm

2-5mm is acceptable

56
Q

What is platform switching?

A

Placing an abutment that is narrower than the implant - could lower chance of peri-implantitis

57
Q

T/F: Tissue around an implant is less capable of containing and repairing damage caused by plaque-induced inflammation.

A

True
