Implant Symposium

Question 1

What is an implant?

Answer 1

Surgically implanted medical device in either mandible or maxilla, which aid in the replacement of missing teeth

Question 2

What is osseointegration?

Answer 2

Direct bone anchorage to an implant body, which will provide a foundation to support a prosthesis

Able to transmit occlusal forces directly to bone, not connective tissue

Question 3

What MH should be considered before implant placement?

Answer 3

Bisphosphonates

Immune suppressant drugs
- steroids
- chemotherapy
- immune suppressants

Radiotherapy

Antiplatelet

Anticoagulant

Question 4

What local considerations must be made before placing implant?

Answer 4

Height of available bone
- distance from ID nerve, mental nerve, maxillary sinus

Width of available bone
- distance to adjacent teeth / implants

Thickness of available bone
- medio-lateral thickness

Gingival biotype

Bone biotype and quality of bone

Question 5

How much distance should be around each implant?

Answer 5

2-3mm top of abutment to CEJ

2mm from implant to adjacent tooth root

3mm from bottom of abutment to blood vessel / nerve

> 7mm CEJ to crown

Question 6

2 stages of osseointegration?

Answer 6

Primary - implant anchored in bone due to frictional forces

Secondary - functional connection between bone and implant. Titanium is inert so bone heals and grows around implant to integrate it
