Final; Dental Implants Infections

Question 1

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

Answer 1

they follow the same pattern

Question 2

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

Answer 2

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

Question 3

What is the difference between peri-implantitis and periodontitis

Answer 3

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

Question 4

True or False

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

Answer 4

true!

Question 5

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

Answer 5

a PRIMARY etiological factor

Question 6

This can create complications for peri-implant disease

Answer 6

bruxism

Question 7

What are 4 possible risk factors for peri-implant disease

Answer 7

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

Question 8

What are two etiological factors involved in tooth loss

Answer 8

deficiency in immune response

genetics

Question 9

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

Answer 9

PIM - only at soft tissue level; like gingivitis

PI - bone loss around implant

Question 10

What is the difference between early and late implant complications

Answer 10

early - before loading

late - after loading

Question 11

What can cause an ailing implant

Answer 11

no stability, but can save it
PIM
PI

Question 12

What can cause a failing implant

Answer 12

PI

Question 13

What can cause a failed implant

Answer 13

PI with mobility and complete loss of osseointegration

Question 14

This is the reversible inflammation of the mucosa surrounding the implant

Answer 14

peri-implant mucositis

Question 15

What clinical manifestations are indicative of PIM

Answer 15

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

Question 16

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

Answer 16

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

Question 17

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

Answer 17

peri-implantitis

Question 18

PI lesions are characterized by what

Answer 18

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

Question 19

In PI, there is direct contact between what

Answer 19

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

Question 20

PI occurs in what percentage of patients

Answer 20

28-56%

12-40% of implant sites

Question 21

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

Answer 21

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

Question 22

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

Answer 22

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

Question 23

What are 5 diagnostic tools used regarding implants

Answer 23

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

Question 24

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

Answer 24

True

Question 25

Mobility of an implant shows wht

Answer 25

lack of osseointegration, but check the abutment first
