Question 1

GTR

Answer 1

A surgical procedure with the goal of achieving new bone, cementum and PDL attachment to a perio. diseased tooth using barrier membranes to provide space maintenance, epithelial exclusion and wound stabilization

Question 2

GBR

Answer 2

A surgical procedure with the goal of augmenting bone volume in edentulous or peri-implant areas using barrier membranes in conjunction with bone grafting materials or biologics

Question 3

Xenograft

Answer 3

A hard or soft tissue graft from a donor species that is different from teh recipient species

Question 4

Autograft

Answer 4

Hard or soft tissue graft that is transferred from a recipient to a donor site within the same individual

Question 5

ADM

Answer 5

An allogenic collagen material that has been treated to remove all cells to provide a matrix to support tissue regeneration and re-vascularization ultimately being transformed into host tissue. ADM is indicated for mucogingival regenerative procedures

Question 6

Tissue Engineering

Answer 6

A technique that utilizes a combination of cells, signaling molecules and scaffolds in an effort to regenerate tissues thereby restoring biological function and structure

Question 7

What is one of the 1st published GTR studies?

Answer 7

Nyman et al. 1982:

M&M: Surgical bony defects created and covered by ePTFE membranes to exclude epith. and CT.

Results: Healing by Regeneration –> new cementum and inserting PDL fibers.

However, the coronal portion near the ePTFE was always CT attachment (“adhesion”)

Question 8

What are the treatment option for root coverage procedures?

Answer 8
