• 3-4mm apical to CEJ of adjacent
tooth 
• 1.5-2mm from adjacent roots

Answer 3

anterior region

Question 4

What mouth region has these bone requirements?

• 1mm buccal bone
• 1.5-3mm apical to CEJ of adjacent
tooth
• 3-4mm from adjacent roots

Answer 4

posterior

Question 5

When the measurement from the dental contact

point to the crest of bone was ___________ the papilla was present 98% of the time.

Answer 5

5 mm or less,

Question 6

When the distance was ____mm, the papilla was

present 56% of the time.

Answer 6

6 mm

Question 7

When the distance was ___ mm or more, the

papilla was present 27% of the time or less.

Answer 7

7 mm

Question 8

The mean height of the papillary tissue

between two adjacent implants is _______

Answer 8

3.4mm (2 to 4mm)

Question 9

t/f: The level of interproximal papilla of the
implant is independent of the proximal bone
level next to the implant.

Answer 9

true

Question 10

t/f: The level of interproximal papilla of the
implant is related to the interproximal bone
level next of the adjacent teeth.

Answer 10

true

Question 11

t/f: Greater peri-implant mucosal dimensions
were noted in the presence of thick peri-
implant biotype vs thin.

Answer 11

true

Question 12

t/f: Minimum 2mm of bone required
between the apical end of an
implant and neurovascular
structures

Answer 12

true

Question 13

What is the minimum amount of attached (keratinized) tissue needed around an implant?

Answer 13

2 mm

Question 14

Staging of implant surgery:
type _: IMPLANT IS PLACED IMM EDIATELY FOLLOWING TOOTH EXTRACTION

• Very difficult procedure. Requires a
very skillful and experienced
surgeon.
• Implant is stabilized mainly in the
apical region.
• Mainly done when all 4 walls of
extraction socket are maintained.
• Great for maintaining papilla
height for anterior teeth.

Answer 14

type I

Question 15

Staging of implant surgery:

type _: IMPLANT IS PLACEDIN A SITE WHERE SOFT TISSUES HAVE HEALEDAND MUCOSA IS COVERING THE SOCKET ENTRANCE

• Similar to immediate loading,
except:
- Allows more soft tissue to
cover extraction site and is
easier to close wound.
- Does not preserve as much
papilla height.

Answer 15

type II

Question 16

Staging of implant surgery:
type _:IMPLANT IS PLACED IN A SITE WHERE SUBSTANTIAL AMOUNTS OF NEW BONEHAVE FORMED IN THE SOCKET

• Allows more bone to be formed
inside extraction socket giving
the implant better stability.
• If bone substitutes are used,
needs to be  of fast resorption
to allow new bone formation
within the 12-16 weeks.

Answer 16

type III

Question 17

Staging of implant surgery:
type _: IMPLANT IS PLACED IN A FULLYHEALED RIDGE

• When extensive grafting is
needed to compensate for
missing bone.
• If bone substitutes are used,
needs to be  of slow resorption
or mixed to allow new bone
formation without resorbing
too quickly.
• Most of the time needs at least
6 months

Answer 17

type IV

Question 18

tissue loss Classes:
Class ___:

buccolingual loss of tissue with normal height in apico-coronal direction

Answer 18

class I

Question 19

tissue loss Classes:
Class ___:

apico-coronal loss of tissue with normal ridge width in buccolingual direction

Answer 19

class II

Question 20

tissue loss Classes:
Class ___:

combination of buccolingual and apico-coronal loss of tissue resulting in loss of normal height and width

Answer 20

class III
