Question 1

Implant with the longest period of clinical trial

Answer 1

subperiosteal

Question 2

Father of modern implantology

Answer 2

Per-Ingvar Branemark

Question 3

4 keys to osseointegration

Answer 3

atraumatic surgery
1mm bone, B & L at crest
No micromovement
Adequate healing time

Question 4

What temperature must not be exceeded during
implant site preparation to make the surgery atraumatic
and avoid bone necrosis

Answer 4

<47 deg C

Question 5

If there is movement in the implant, what
integration will there be: fibro-osseous or
osseointegration

Answer 5

Fibro-osseous/unacceptable

Question 6

5 Criteria for implant success

Answer 6

immobile
Less than 0.1mm bone loss annually (used to be
0.2mm/annually)
No pain, infection, neuropathies, paresthesia, or
IAN violation
No x ray evidence of peri-implant radiolucency
85% still in 10 yrs = success

Question 7

)ITI-implant system titanium type and implant

placement

Answer 7

commercially pure titanium
Single stage transcended through gingival into oral
cavity

Question 8

How is ITI different from Branemark

Answer 8

Branemark said implant should be two stage &

level with bone

Question 9

Core-Vent implant system titanium type and

implant placement

Answer 9

titanium-6 aluminum-4 vandium alloy

2 stage

Question 10

)How is Core-Vent different from Branemark

Answer 10

does not use commercially pure titanium

Question 11

If pt needs ortho, should it be done before or after

implant placement

Answer 11

before. Implants don’t move

Question 12

Integral-Calcitek implant system titanium type and

implant placement

Answer 12

hydroxyapatite coated bullet form

Tapped into hole

Question 13

)With implant systems are the parts

interchangeable between systems

Answer 13

no

Question 14

3 basic components of dental implant

Answer 14

Implant body
Abutment
Retaining screw

Question 15

Titanium types/coating

Answer 15

(commercially pure) titanium
 Titanium alloy (Ti6Al4V)
 Titanium plasma sprayed (TPS)
 Hydroxyapatite coated (HA)
 Microtextured
 Combination (micro-textured and HA)

Question 16

3 terms describing implant/bone interface

Answer 16

fibro-osseointegration
Osseointegration
Biointegreat

Question 17

what is advantage of microtextured titanium

Answer 17

)uniform 1-2 micron surface roughness gives 44%

more surface area than mechanical titanium

Question 18

Where is Type I bone found

Answer 18

anterior mandible

Question 19

Where is Type 2 bone found

Answer 19

posterior mandible

Question 20

Where is Type 3 bone found

Answer 20

anterior maxilla

Question 21

Where is Type 4 bone found

Answer 21

posterior maxilla

Question 22

Where do implants work better, maxilla or

mandible

Answer 22

mandible

Question 23

Which bone type osseointegrates fastest even

though it has the lowest blood supply

Answer 23

Type 1

Question 24

Why is Type 1 bone the best for implants

Answer 24

because majority of implant is in thick cortical

bone

Question 25

Why is a tapered implant good to use in type 4 | bone

Answer 25

it compresses that bone increasing the mechanical | retention

Question 26

)Which place is most difficult for implant placement | and why

Answer 26

Posterior. Greatest force, least space, poorest | bone quality, anatomic structures (IAN, Max Sinus)

Question 27

)natural tooth biomechanics dissipate lateral | occlusal forces how

Answer 27

by PDL

Question 28

) Ideal implant biomechanics direct occlusal forces | how

Answer 28

along vertical axis of implant, dissipate periapically

Question 29

Where are lateral occlusal forces concentrated in an implant Where are lateral occlusal forces concentrated in an implant

Answer 29

at crest of ridge on abutment screw

Question 30

Failing vs Ailing implant

Answer 30

ailing still has some osseointegration

Question 31

How far can a cantilever be placed

Answer 31

1.5 times the A-P spread

Question 32

What does a cantilever do with forces

Answer 32

increases force at crest and on abutment screw

Question 33

How do you place three or more implants in a row

Answer 33

offset to give a tripod effect

Question 34

All torque is measured in

Answer 34

Newtom centimeters

Question 35

What is the max angle on an angle abutment that has been found to not significantly effect occlusal loading

Answer 35

30 deg

Question 36

What diameter should be chosen for the implant

Answer 36

largest diameter that leaves 1mm bone B & L and | allows for coronal anatomy

Question 37

What is the problem with long implants

Answer 37

lot of heat generated at most apical portion | Longer implants have higher failure rate

Question 38

What is the ideal implant length

Answer 38

11-13 mm

Question 39

Maximum crown to implant ratio

Answer 39

1:1

Question 40

What are 2 contraindications for a long implant in | posterior mandible

Answer 40

``` retromylohyoid line (thin) IAN ```

Question 41

Minimum amount of space between edge of | implant and adjacent tooth

Answer 41

1.5 mm

Question 42

Minimum amount of space between edges of | adjacent implants

Answer 42

3 mm

Question 43

What type of occlusion is desirable on implants

Answer 43

light centric and no lateral contacts
