20
Q

indicated for 1 year of stable probing depths

A

26
Q

pathologic process involving the region of the soft tissue
above the crest of bone

A

gingivitis

27
Q

gingivitis can be…

A
  1. plaque-associated
  2. acute necrotizing
  3. ulcerative
  4. hormonal
  5. drug-induced
  6. spontaneously occuring
28
Q

(peri-implant disease) indicates peri-implantitis and consequent bone loss

A

exudate

29
Q

(peri-implant disease) can occur due to reduced amount of bone

A

secondary occlusal trauma

30
Q

treatment for peri-implant disease

A
  • short-term antibiotic treatment
  • chlorhexidine
  • aggressive professional and patient care
31
Q

treatment for presence of exudate persisting for more than 1-2 weeks

A
  • force reduction
  • surgical management of condition
32
Q

neither an indicator of clinical health nor of the state of rigid fixation

A

percussion

33
Q

“ringing” sound in percussion corresponds to…

A

presence of “some” bone at the interface

34
Q

most useful diagnostic tool in determination of a healthy implant

A

crestal bone region

35
Q

used primarily to determine the need for initial preventive therapy

A

crestal bone loss

36
Q

usually a result of stress at the perimucosal site

A

early loss of crest bone

37
Q

implant failure indications

A
  • horizontal mobility beyond 1mm or any clinical observed vertical movement under less than 500g force
  • rapid progressive bone loss regardless of stress reduction or peri-implant therapy
  • pain during percussion or function
38
Q

a scale presented for implant quality based on clinical evaluation; first established by James and modified by Misch

A

Implant Quality Scale

39
Q

Implant Quality Scale groups

A
  • Group 1
  • Group 2
  • Group 3
  • Group 4
  • Group 5
40
Q

(Implant Quality Scale) Group 1

A
  • optimum conditions
  • bleeding index: 0-1; early indicator of soft tissue problems
41
Q

(Implant Quality Scale) Group 2

A
  • implants are stable but show history of clinical problems
  • bleeding index: 0-2
42
Q

(Implant Quality Scale) Group 3

A
  • questionable quality
  • warrants clinical therapy
  • exudate: may last more than 1-2 weeks in preceding 3 years
  • bleeding index: 1-3
43
Q

(Implant Quality Scale) Group 4

A
  • clinical failure
  • should be removed under 5 conditions
44
Q

5 conditions of Group 4 implant removal

A
  1. pain on palpation or function
  2. > 1mm mobility horizontally
  3. any vertical mobility or progressive bone loss
  4. uncontrolled exudate
  5. generalized radiolucency “sleepers”
45
Q

(Implant Quality Scale) Group 4

A
  • implants surgically removed or exfoliated
  • no longer in mouth
