Q

How often should implant patient with pathology go?

1.5 mm

38
Q

Thickness of acrylic in over denture (even over the locator abutments)

A

2 mm

(on slides it said 2.5 mm)

39
Q

Radiographic follow up protocol for normal implant patient:

A

1) Initial placement
2) 6 months
3) 12 months
4) every 2 years *** if no pathology present

40
Q

According to some regulation which is true?

a) mandibular over denture requires 2 implants

b) mandibular over denture requires 4 implants

c) maxillary over denture requires 2 implants

A

a) mandibular over denture requires 2 implants

41
Q

Screw retained vs. cement retained question

A

Cement:
- more permanent (can’t screw off like screw retained) also because of this if abutment becomes loose entire restoration is ruined
- hard to remove excess cement which can lead to peri-implantitis –> implant failure
- minimum vertical space 7mm

Screw retained
- provides retreivability
- less esthetic
- less strong
- minimum vertical space 4mm

42
Q

impression coping remains on the implant during the impression making and removal of the set impression from the mouth; the coping is removed from the implant and then attached to the implant analogue

A

Closed tray impression technique

-less accurate
-used when teeth are parallel

43
Q

-more accurate
-harder to perform
-used when teeth are not parallel

A

Open tray impression technique

44
Q

T/F: A verification radiograph of the fully seat impression coping is typically done before taking the impression

A

True

45
Q

What resorbs first after impression?

A

Bundle bone

46
Q

T/F: Mose people have thinner buccal than lingual bone

A

True

47
Q

can the gingival contour change due to the provisional crown?

A

Yes

48
Q

T/F: CBCT exposes patient to LESS radiation than medical CT

A

True

49
Q

T/F: CBCT is better for soft tissue imaging than medical CT

A

False

Medical CT –> Better for soft tissue imaging

50
Q

What type of X-ray can you check magnification by placing a 5 mm bead?

A

Pano

51
Q

If X-ray shows non-seating of impression coping what do you do?

A

Reposition & reseat until FULLY seated

52
Q

All are true of tooth implant supported prosthesis except:

a) definite cementation (permanent; no screw retention or temp cement)
b) short span
c) stress breaking connectors
d) avoid telescopic crowns (no copings)

A

c) stress breaking connectors

CANNOT have stress breakers, need to be rigidly connected to tooth and implant
