Question 1

What is the success criteria for implants?

Answer 1

No mobility
No radiolucency
Bone loss <0.2mm after the first year
Esthetically Satisfying

Question 2

What is the success rate for implants based on the A/S/Z success criteria?

Answer 2

85% at 5 years

80% at 10 years

Question 3

Define Osseointegration

Answer 3

A direct connection between living bone and a load carrying endosseous implant at the light microscopic level

Question 4

What prerequisites are necessary to achieve successful osteointegrated bone-to-implant interface?

Answer 4

Atraumatic surgery
Immediate stabilization of the implant
No loading during initial integration
A Passive stress distributed prosthetic technique

Question 5

What are the keys to osseointegraiton?

Answer 5

Atraumatic surgery (<47’ C)
1mm bone B and L at the crest
No micro-movement
Adequate healing time (6 mo)

Question 6

What current materials are used for cylindrical implants?

Answer 6

Inert materials
A lot of implants today are stronger than titanium alloy
We have roughened and acid etched implants that can help the bone grow faster
