Biological Mediators Flashcards
These cells are responsible for making new PDL.
Fibroblasts
When do you get a long epithelial attachment?
When the epithelial cells from the flap migrate downwards.
Perio therapy to restore cementum, PDL, and alveolar bone what was lost from periodontitis.
Regeneration
When we cut tissues away rather than regenerate them.
Resection
Need this kind of closure when placing a graft or barrier membrane.
Primary (sutures)
Excluding the epithelia while causing regeneration of the PDL and alveolar bone.
Guided Tissue Regeneration (GTR).
What are barrier membranes a barrier to?
Gingival epithelium and CT from entering the site.
What do barrier membranes allow into the site?
Fibroblasts and osteoblasts to form new CT and bone.
In addition to barrier membranes, these are used to create a barrier from epithelial cells and CT cells.
Bone grafts
A scaffold for osteoblasts to form new bone.
Osteoconductive.
A scaffold + BMP’s to induce mesenchymal cells to differentiate into OSTEOBLASTS.
Osteoinduction
Bone grafts are best for what walled defect?
3
Bone grafts do not work for what walled defect?
1
Allows mesenchymal cells to morph into bone cells.
BMPs
The only molecule that can TRANSFORM a mesenchymal cell to an osteoprogenitor cell.
BMP
A commercial BMP
Infuse bone graft
Term for this:
Localized alveolar ridge augmentation following extraction.
You extract the tooth and fill the hole with bone.
Socket preservation
Poke some bur holes into the cortical bone to allow for bleeding, which makes the graft take to the bone.
Cortical penetration
Mobility of the implant means it has lost this.
Osseointegration
This is a radiographical indication that new bone is forming.
Trabeculation
A bonvine-derived xenograft that comtians BMPs.
Bio-Oss
From the same person.
Autologous
From the same species.
Allogenic
Froma different species.
Xenograft
