Dental Implants Maintenance

Question 1

What 3 parameters should be measured and monitor in dental implant patients?

Answer 1

1. BOP
2. Peri-implant pocketing
3. Stability of crestal bone levels (CBL)

Question 2

What causes early implant failure?

Answer 2

Usually the failure of the initial integration to take place during the healing phase

Question 3

What 2 reasons cause late implant failure either individually or collectively?

Answer 3

1. Biological failure e.g. plaque-induced peri-implant disease
2. Mechanical failures e.g. screw or abutment loosenin

Question 4

What is the treatment for a failed implant?

Answer 4

There is NO treatment for a failed implant

Question 5

List 2 systemic disease and 2 local risk factors of implant failure:

Answer 5

Systemic:
1. Uncontrolled diabetes
2. Immunosuppression

Local:
1. Smoking
2. Radiotherapy

Question 6

What 4 areas are targeted to reduce risk factors and promote implant success?

Answer 6

1. Implant design
2. Soft tissue quality and quantity
3. Patients factors e.g. smoking
4. Patient Motivation

Question 7

What is the desired flossing technique for implant patients?

Answer 7

The cross-over floss technique

Question 8

What 4 different additional cleaning tools can be used to help maintain good OH in implant patients?

Answer 8

1. ID brushes
2. Superfloss
3. Single-tufted brushes
4. Air/water flossers

Question 9

What is the acceptable level of bone loss for the first year and then annually in implant patients?

Answer 9

1. <1.5mm in first year
2. 0.2mm each year after

Question 10

What type of radiograph is used to monitor bone levels in implant patients?

Answer 10

PA

Question 11

What is the definition of biological width?

Answer 11

The natural seal that develops around teeth protecting the alveolar bone from infection

Question 12

What is the standard measurement of biological width and what does it represent?

Answer 12

Biological width = 2.04mm

Represents the sum of the epithelial and connective tissue measurements

Question 13

What is the typical biological width around an implant and what is it made up of?

Answer 13

2-3mm for implants:

2mm= epithelial attachment
1mm= supracrestal connective tissue attachment

Question 14

What 2 outcomes can occur if the biological width is violated?

Answer 14

1. Gingival inflammation only
2. Gingival inflammation with bone loss

Question 15

How is peri-implant mucositis diagnosed?

Answer 15

BOP with gentle probing with a calibrated probe

Question 16

What 3 indices are used to determine the health of the peri-implant tissue?

Answer 16

1. BOP
2. Pocket probing depths (PPD)
3. Presence of plaque, suppuration or mobility

Question 17

What cleaning is most suitable for implants?

Answer 17

Air polishing

Question 18

What is recommended to treat peri-mucositis?

Answer 18

An antiseptic mouthwash e.g. Corsodyl

Question 19

What bacteria plays the most important role in implant failure?

Answer 19

Spirochetes and mobile forms of gram-negative anaerobes
