17
Q

Why are cemented prosthesis more Riley to be affected by biological complciaotns

Study These Flashcards
A

Can be difficult to clear cement for the edges leading to biological interactions and complications

18
Q

Give examples of biological complications affect peri implant tissues

Study These Flashcards
A
  1. Peri implant mucositis
  2. Peri implantitis
  3. Plaque induced conditions
19
Q

What is Peri implant mucositis

Study These Flashcards
A

Reversible inflammatory reaction in the soft tissues

20
Q

How many patients are affected by Peri implant mucositis

21
Q

What is Peri implantitis

Study These Flashcards
A

Inflammatory reaction in the tissues surrounding an implant with loss of supporting bone

22
Q

How many patients are affected by Peri implantitis

23
Q

How do you assess an implant

Study These Flashcards
A
  1. visually
  2. Palpate it
  3. Is it mobile
  4. Smoker
  5. Oral hygiene
24
Q

What do you examine visually when assessing a dental implant

Study These Flashcards
A
  1. Colour
  2. Consistency; is there any swelling present
  3. Sinus
  4. Recession
25
What type of probe do we use to assess an implant
plastic probe
26
How much force should we use to assess an implant
25g around teeth | 15g around implant
27
What are we looking for when probing around an implant
1. 6 points 2. Bleeding on probing 3. Probing pocket depths 4. Suppuration
28
Do we do BPEs around an implant
NO
29
What don't we use BPEs around implants
Because the bone level is more variable around an implant
30
What does implant mobility indicate
Implant failure due to loss of osseointegration
31
How do assess the bone levels around an implant
Radiographic examination
32
Which radiographs can we take to assess bone levels
Panoramic | Periapical
33
When should we take radiographs to assess bone levels of an implant
2 yearly intervals or if any changes assessed
34
What habit can lead to increased failure risk of implant
Smoking
35
By how much can smoking increase implant failure
2.6 times
36
Smoking increases the risk of which bioligcla complication
Peri implantitis by 36.5%
37
How can periodontal history affect implant success
Rate of implant failure/ complications is higher in patient with a history of treated periodontal disease
38
What do we assess when looking at a patients dental history
Periodontal health | patietn attendance
39
When looking at etc implant restoration what do we look at
1. Linked units 2. Contour 3. cement tupe 4. Margin postion
40
How do we treat peri implant disease
Early and aggressively by: 1. Giving OHI 2. Non surgical debridement on a 6 or 3 month basis 3. Modify the prosthesis ?
41
What can we use to carry out non surgical treatments of implants
Plastic carbon fibre enforced scalers are better as they are less likely to scratch the titanium
