Question 1

)If doing a two-stage implant, how long after
uncovering should you wait before final restoration of
the implant

Answer 1

6 weeks

Question 2

Can implant placement and bone grafting be done

at the same time

Answer 2

Yes, if there is primary stability and minimal

grafting required

Question 3

What is required for primary stability to place an

implant immediately after extraction

Answer 3

must engage 5 mm or more bone, either apically

or horizontally

Question 4

What is the critical space in the extraction

socket

Answer 4

distance between implant platform and edges of

extraction socket. Should be <2mm

Question 5

Which is usually a better candidate for immediate
implant placement after extraction: anterior or
posterior

Answer 5

Anterior teeth because diameter of implant is

close to CEJ diameter of extracted tooth

Question 6

Why are posterior extractions not a good

candidate for immediate implant placement

Answer 6

posterior teeth have wider diameter than implant

so socket exceeds critical space of <2mm

Question 7

)Implants are most often made of

Answer 7

Titanium

Question 8

) The rough surface of implants is

Answer 8

desirable for improved osseointegration

Question 9

Osseointegration means

Answer 9

40%-70% bone/implant contact

Question 10

First even leading to osseointegration that occurs

after implant placement is

Answer 10

)formation of a blood clot

Question 11

Excessive force on implant crowns results in

Answer 11

fatigue of implant components, leading to fracture

Question 12

) Preload is

Answer 12

tension placed by screws to protect implant

components from displacing forces

Question 13

Plaque and calculus

Answer 13

accumulate on implants similarly to teeth

Question 14

Connective tissue fibers around the implant neck

are

Answer 14

parallel to implant surface

Question 15

Peri-implantitis

Answer 15

spreads rapidly to bone

Question 16

Implant survival

Answer 16

means implant still present in mouth after a

period of time

Question 17

Minimum interarch space for a fixed implantsupported

prosthesis

Answer 17

7 mm

Question 18

Ridge mapping measures

Answer 18

soft tissue thickness clinically to deduce bone

width

Question 19

Panoramic radiographs are useful for

Answer 19

ruling out bony pathologies and estimating bone

availability

Question 20

Computed tomography

Answer 20

most precise radiographic technique

Question 21

Cone beam computed tomography

Answer 21

uses less radiation than conventional computed

tomography

Question 22

Hounsfield numbers are

Answer 22

arbitrary numbers set for tissue density on

computed tomographs

Question 23

Radiographic templates are

Answer 23

used to visualize diagnostic teeth

Question 24

A scannographic template is

Answer 24

aide to visualized diagnostic teeth on a computed

tomography image

Question 25

Which bone is the densest: D1 or D4

Answer 25

D1

Question 26

What amount of bone is required buccal and

lingual when selecting and implant

Answer 26

1 mm bone buccal and lingual of implant

Question 27

What is an advantage of screw-retained

prostheses

Answer 27

ease of retrieval

Question 28

What is an advantage of cemented

prostheses

Answer 28

ease of fabrication

Question 29

)Should connecting implants and teeth be avoided

at all costs, or avoided but can be performed(

Answer 29

should be avoided whenever possible, but can be

performed with careful consideration

Question 30

Distal cantilevers should be avoided whenever
possible, but if must be used, they should be limited to
what type of span

Answer 30

short spans

Question 31

Immediate implant placement is

Answer 31

placement of an implant at the time of tooth

extraction

Question 32

Immediate loading is

Answer 32

placement of a restoration at the time of implant

placement

Question 33

Should provisional restorations rest on bone grafts

or newly placed implants

Answer 33

no

Question 34

Bone grafting works best to augment ridge height

or ridge width

Answer 34

Ridge width

Question 35

) Gingival grafts should be performed prior to
fabricating final restoration or after the final restoration
is delivered

Answer 35

prior to fabricating final restoration
