18
Q

Must an implant always be placed at the same

level in the bone

A

No, varies, can be level with crest, slightly above

crest or collar above crest

19
Q

4 reasons for the variability in depth of implant

A

limited intra-arch space
Narrow bone bucco-lingual
Esthetics
Increase crown:root ratio

20
Q

This determines initial stability of the implant and

prevents over tightening the implant

A

surgical torque wrench

21
Q

Primary stability with the surgical torque wrent

between ___ and ___ Ncm

A

35-40 Ncm

22
Q

What is used in the surgical area and with the

instruments

A

copious cooled irrigation

23
Q

What is drill speed for the tapered groovy and

dense bone drills

A

800 rpm

24
Q

)What is the drill speed for the straight groovy bone

drills

A

2000 rpm

25
Q

What is the rpm/ Ncm for screw tap drilling

A

25 rpm or 45 Ncm torque

26
Q

What is the rpm/Ncm for implant placement

A

25 rpm or 20-45 Ncm torque

27
Q

What is the final torque with the torque wrench

A

35-45 Ncm

28
Q

What motion is used for implant site drilling

A

in and out with drill in bone for 1-2 seconds

29
Q

How far does the drill preparation extend beyond

the implant

A

1mm (must be accounted for in treatment

planning)

30
Q

which drill type is single use: tapered or straight

A

Straight

31
Q

When are tapered drills to be replaced

A

after 20-30 uses or when cutting efficiency lessen

32
Q

Heat generated from drill can be transmitted how

far in bone and what does this ultimately result in

A

> 3mm, implant failure

33
Q

Do not exceed what temperature when preparing

site

A

47 deg C

34
Q

Factors to minimize heat

A

copious cooled irrigation
Incremental drilling
Intermittent drill pressure
New (sharp) drills

35
Q

Rule for placing implant

A

2mm below adjacent CEJ or gingival margin

36
Q

Rule for bone graft in socket at implant placement

A

bone graft if space larger than 2mm

37
Q

2 uses for a surgical guide

A

implant placement

Index implant for temporary crown

38
Q

Posterior occlusal tables should be _____to

alleviate lateral occlusal forces

A

Narrow

39
Q

Of the 3 flow charts for approaches to treatment,

what was the first consideration before the implant

A

Site: immediate implant at EXT site
Site: Flap technique
Site: Flapless technique

40
Q

With the 3 flow charts for approaches to
treatment, after it is determined what the site will be
(e.g. EXT site, flap, flapless), what is asked next

A

Bone graft or no bone graft

41
Q

With the 3 flow charts for approaches to
treatment, after it is determined what the site will be
(e.g. EXT site, flap, flapless), what is asked next

A

Bone graft or no bone graft

42
Q

With the 3 flow charts for approaches to
treatment after it is determined if the site will require a
bone graft or not, what are the common options in all 3
graphs

A

)healing abutment or immediate provisionalization

43
Q

With the 3 flow charts for approaches to
treatment the Immediate placement at EXT site and the
Flap site, when it required a bone graft, what was the
other option besides healing abutment or immediate
provisionalization

A

2 stage implant

44
Q

Wit the 3 flow charts for approaches to treatment,
what is the consideration in all of them in the esthetic
zone

A

connective tissue graft with or without bone graft
