1
Q

What is the pattern of early microbial colonization in regards to titanium implants and teeth

A

they follow the same pattern

2
Q

What is the main difference between plaque build-up regarding implants and teeth

A

with increasing the duration of plaque build up (3 months) the duration of the peri-implant mucosa expands more and progresses further “apically
than in the case of the gingiva

3
Q

What is the difference between peri-implantitis and periodontitis

A

peri-implantitis is a microbial heterogenous infection with predominantly gram-negative species and is less complex

4
Q

True or False

the peri-implant micro biome differs significantly from the periodontal community in both health and disease

A

true!

5
Q

What type of etiological factor is occlusal trauma regarding peri-implant disease

A

a PRIMARY etiological factor

6
Q

This can create complications for peri-implant disease

A

bruxism

7
Q

What are 4 possible risk factors for peri-implant disease

A

smoking
uncontrolled systemic disease (effect on healing)
radiation therapy
patients with a history of periodontitis

8
Q

What are two etiological factors involved in tooth loss

A

deficiency in immune response

genetics

9
Q

What is the difference between peri-implant mucositis and peri-implantitis

A

PIM - only at soft tissue level; like gingivitis

PI - bone loss around implant

10
Q

What is the difference between early and late implant complications

A

early - before loading

late - after loading

11
Q

What can cause an ailing implant

A

no stability, but can save it
PIM
PI

12
Q

What can cause a failing implant

A

PI

13
Q

What can cause a failed implant

A

PI with mobility and complete loss of osseointegration

14
Q

This is the reversible inflammation of the mucosa surrounding the implant

A

peri-implant mucositis

15
Q

What clinical manifestations are indicative of PIM

A

presence of bacterial plaque and calculus
edema, redness, and mucosal hyperplasia
bleeding on probing
exudate or pus formation on occasions
no radiological evidence of bone resorption

16
Q

The peri-implant mucosa seems less effective than the gingiva in what

A

encapsulating plaque-assocaited lesions; thus, the existence of gingivitis is riskier for implants

17
Q

This is an inflammatory reaction associated with loss of supporting bone around an implant in function

A

peri-implantitis

18
Q

PI lesions are characterized by what

A

the presence of numerous neutrophils in the tissue surrounding the implant (not seen in periodontitis)

19
Q

In PI, there is direct contact between what

A

plaque on the implant surface and the inflamed connective tissue (not seen in periodontitis)

20
Q

PI occurs in what percentage of patients

A

28-56%

12-40% of implant sites

21
Q

What are the 6 clinical factors used to evaluate peri-implant health

A
  1. absence of motility
  2. radiographic examination
  3. absence of bone loss ≥0.2mm/year follow the first year
  4. absence of any pain, complaint, or infection
  5. functional and esthetic acceptance of implant
  6. a success rate of 94-98% following 5 years, and 90-94% following 10 years
22
Q

What are the factors that play into the decision making in tooth extraction and implant placement

A
anatomy/bone quality
perio/restorative/endo status
systemic health
economics
compliance and motivation
23
Q

What are 5 diagnostic tools used regarding implants

A
probing of peri-implant mucosa
bleeding on probing
suppuration
radiographic interpretation
mobility
24
Q

True or False
There is NO correlation between plaque accumulation and the amount of marginal tissue inflammation, probing depth, and bone loss

A

True

25
Q

Mobility of an implant shows wht

A

lack of osseointegration, but check the abutment first
