Wound Healing And Osseointegration Flashcards
What happens to the alveolar ridge after extraction?
THE RIDGE WILL CHANGE SHAPE
Macroscopic and microscopic changes to the alveolar ridge
There is buccal bone loss
Narrowing of the band of attached gingiva, and effectively coronal shifting of the MGJ (mucogingival junction)
Why is it important if the shape of the ridge changes?
What are the implications for restorative treatment if the alveolar ridge changes shape ?
Implications for restorative treatment
Does an implant stop ridge resorption?
No
What do you need to place an implant?
At least 1mm of bone layer thickness all around an implant
(Can be diff bone layer thickness needed for diff types of implants)
Timing of an implant
How does timing of when an implant is placed affect bone loss?
How should an implant be placed?
How does implant placement affect emergence of a restoration?
What can we do for implants to achieve good emergence profile ?
Implications for implant treatment
Implant placement has to be restoratively driven
What is important to consider for the aesthetics of an implant?
What is osseointegration ?
What is osseointegration dependant on?
osseointegration - what do we want ?
Principles of osseointegration
(Stages of osseointegration )
How can you change the implant surface to encourage osseointegration ?
Ie how does the implant surface influence osseointegration
1) increase roughness
2) flouride loading

What is the Importance of roughened surface?
Timing of osseointegration: what happens after:
4 days?
1 week?
2 weeks?
4 weeks?
12 weeks?
What is contact osteogenesis?
De novo = new
What is TiOblast surface
Healing/ remodelling around SLA surface in human model
SLA - sandblasted , large grit , acid etched implant - creates surface roughness with goal of enhancing osseointegration through greater bone to implant contact
Through osseointegration , there is more stability of implant and therefore improved longevity
