Q

How does Bio-Oss work?

A

Causes clot stabilisation –> revasularisation and migration of osteoblast –> growth of woven bone enhance by scaffold of BioOss
Bone integration

Q

How to use Bio-Glass?

A

Introduce into defect site –> react w/ body fluids

Modified surface bioglass induces tissue regeneration

Q

What is GTR?

A

Placing a membrane barrier to cover bone and PDL - separates bone and PDL from gingival epithelium
Prevents epithelial migration favouring repopulation by cells PDL/bone

17
Q

What does Emdogain do?

A

Differentiate cells at dental follicle into cementoblast

A

Intra-bony defects

Recession

19
Q

What is procedure for tx of recession w/ Emdogain?

A 
Coronally advanced flap
Root surface conditioning
