Q

•Important to avoid perforaMng the lingual plate
during preparaMon of the implant site since
perforaMons can result in extensive and even life-
threatening bleeding (Bruggenkate et al, 1993)
•Reflec*ng a lingual flap in order to visualize the
ridge is a safe way of performing surgery

Q

____ stage implant placement

can begin.

Q

___ stage implant placement
•The implant is “buried” under the sol tissues
•In this case we do not use an healing abutment but a
cover screw.
•Preferred in case of big bone augmentations and
when the primary stability is not optimal
•Wound Protection
•Will require a 2nd surgery in 3-4 months to uncover
the implant.
•A 2nd chance to correct any sol Mssue deficiencies.

• - at least ____ mm between teeth and
implant

A

Q

A

3-4mm

29
Q

___ mm between 2 adjacent implants

A

3 mm

30
Q

BUCCO-LINGUAL (anterior zone)
- As bone thickness approached ____ - ____mm,
bone loss decreased significantly and some
evidence of bone gain was seen

A

1.8 - 2 mm

31
Q

IN posterior, how many mm is needed BL bone for implant?

A

1 buccal 1 lingual so 2 mm total

32
Q

Concept of placing an abutment of a
narrower diameter on the implant of a wider
diameter to preserve alveolar bone levels at
the crest of a dental implant

  • It reduces per-implant bone resorption at the one crest:
  • Shils the inflammatory cell infiltrate inward and way from the adjacent crestal bone
  • Maintains the supracrestal attachment
  • Increases distance of implant-abutment junction from the crestal bone
  • limits possible interface of bone with micro-movements
A

Platform switching

membranes with bone grafts to augment
atrophic bony ridge

Q

Is crown to root ratio valid for implants?

A

Nope

39
Q

How many mm is lost on average horizontally post extraction?
