true

bc growing an organ around the implant

Question 2

reconstruction o the periodontal unit [alveolar bone, PDL, and cementum]

1. bone graft and bone substitutes
2. guided tissue regeneration

3.

Question 3

new CT attachment

Answer 3

new CT on a root surface that has been

previously deprived of its PDL

Question 4

instead of periodontal regeneration you can have bone fill

Answer 4

true

Question 5

waht is bone fill?

Answer 5

clinicall restoration of bone in a previously treated periodontal defect [does not

Question 6

Periodontal regeneration can ONLY BE DONE with ______ bone loss

Answer 6

vertical bone losss ONLY

Question 7

when you cant solve the pocket problem that the patient has and you cant fix it through repair and resection you do periodontal regeneration

TF

Answer 7

true

Question 8

TF

resection is appropriate for advanced periodontal destruction

Answer 8

false

NOT APPROPRIATE

Question 9

waht are the 4 indications of vertical bone loss?

Answer 9

deep vertical defects

aggressive periodontitis [LKP} defects

anatomical limitations

esthetic areas

furction invasions

Question 10

of the 5 which one is the most common vertical bone loss ?

Answer 10

deep vertical defects

Question 11

furcation invasion _____ mm horizontal component

Answer 11

greater than or equal to 4 mm

Question 12

cortical bone is _____ and if you need blood supply for periodontal regneration and instead of hte PDL adj from taht area and the flap we get it from _____

Answer 12

avascular

use high speed bur and decortication and series of perforation until you reach cancellous bone to enhance blood supply

Question 13

when you use a bone graft we do NOT –_____ and if you with material you wont get _____ and go to the level of the exisitng bony levels

Answer 13

overfill

primary closure

Question 14

with an open wound ______ washes away and an ____ chance of infection

Answer 14

material

increased chance of infection

Question 15

autographs

extra oral [hip bone extraction] and has to be in the surgery room

2. not used anymore

TF

Answer 15

true

true

Question 16

allografts

are material from the ___ species taht come from ____

Answer 16

same

cadavers

Question 17

the two types of allografts

Answer 17

freeze- dried bone

decalcified freeze-dried boen

Question 18

xenografts

comes frm a _____ species and the mineral material is very similar to human _____ bone

Answer 18

different

cancellous

Question 19

TF

xenograft bovine - dervied prous bone material will be absored very slowly

Answer 19

true

slowly and may not be compltely resorbed ever

Question 20

if the material was demineralized like allograft will DISAPPEAR COMPLTELY

TF

Answer 20

true

Question 21

\

choice of osseous graft material is not the most important what is most imporant?

Answer 21

clearing the root surface of calculus

Question 22

when you do periodontal regernation the incision is always in the ____

Answer 22

sulcus

Question 23

TF

you should completely fill the defect with bone graft in clincial cases

Answer 23

false

filling 60 - 70 % of defect so room for partial success and a case for failure

Question 24

TRUE new periodntal generation attachment can be done with just bone graft but is ______

Answer 24

unlikely

Question 25

if you dont use anything and just use bone graft material you will **always ** get more _____ and ____ pocket depth

Answer 25

more attachment

greater pocket depth

Question 26

cells we like are bone cells make bone

cells from the root make cementum

which cells do we not like

Answer 26

dont like cells from the CT proper

cells from the flap [epithelial cells]

bc stop cells we do like to migrate to the defect

Question 27

which cells are faster and which ones are slower?

Answer 27

epithelial cells from the flap are faster

slower ones are the bone and cementum making cells ones we want to go to the defect for periodontal regeneration

Question 28

when epithelial cells go the defect first what is most likely to happen?

Answer 28

root resorption

Question 29

which type of resorable membrane is the most common one?

Answer 29

collagen

Question 30

how long does the resorable memebranes need to be there for guided tissue regeneration

Answer 30

6 - 8 weeks

Question 31

new attachment true periodontal is more likely than ____ ___

Answer 31

osseous grafting

Question 32

probing is much more imporant than x rays

tf

Answer 32

true
