JVD 2019 #4 Guided Tissue Regeneration Therapy with Bone Augmentation in a Lingual, Infrabony Osseous Defect of a Mandibular Canine; Bebel

Question 1

What does the technique of guided tissue regeneration do?

Answer 1

Encourages healing of periodontal pockets by regeneration of new attachment, lost bone reconstruction, and reestablishment lost periodontal ligaments, gingival fibers, and junctional epithelium

Question 2

What was used for GTR?

Answer 2

Canine demineralized freeze-dried membrane allograft (DFMBA)

Question 3

What is the goal of GTR?

Answer 3

To have a root surface repopulated first by periodontal cells to promote formation of new attachment.
If gingival epith cells, connective tissue cells, or bone cells predominate initially, a weaker long junctional epith union or TR or root ankylosis may result.

Question 4

Define osteoinduction

Answer 4

Chemical process by which molecules, such as bone morphogenic protein in a bone graft convert neighboring cells into bone-producing osteoblasts.

Question 5

Define osteoconductive

Answer 5

structural framework or scaffold for clot development, maturation and remodelling. No biological influence on surrounding tissues.

Question 6

Define osteointegration

Answer 6

Bonding of the host and graft material, resulting in new bone. Necessary for graft survival.
