Chapter 17

Question 1

Available implant should be evaluated closely for implant in esthetic regions because of:

a-	It’s influence on the soft tissue drape
b-	Implant size
c-	Implant insertion (angulation and depth)
d-	Final prosthetic result
a-	a, b and d
b-	b and d
c-	a,b and c
d-	All of the above

Answer 1

d- Final prosthetic result

Question 2

The elimination of the vertical lines in the lip is achieved by:

a- Bulking out the labial flange and teeth of an overdenture
b- Positioning the teeth farther forward than the natural teeth position
c- Plastic surgery and bone augmentation
d- Increasing of the implant number to be placed.
a- a, b and c
b- b
c- b and c
d- All of the above

Answer 2

b- Positioning the teeth farther forward than the natural teeth position

Question 3

The primary criterion to determine whether a fixed restoration, a bone graft and fixed restoration or a maxillary overdenture is indicated is:

a- The labial position of the lip in relationship to the premaxilla
b- The width of the residual ridge
c- The amount and the type of the forces which will be applied to the prosthesis
d- The implants position

Answer 3

a- The labial position of the lip in relationship to the premaxilla

Question 4

To augment a premaxilla

a- Synthetic materials are usually necessary
b- Allograph materials are usually necessary
c- Autologous bone grafts(iliac crest graft) are usually necessary
d- Bio-oss mixed with PRP are usually necessary

Answer 4

?

Question 5

The anatomical problem for the implant treatment in the posterior maxilla is

a- The wide buccal frenum attachment
b- The large roots of the first molar
c- The rapid expansion of the maxillary sinus after tooth extraction
d- The infraorbital nerve.

Answer 5

c- The rapid expansion of the maxillary sinus after tooth extraction

Question 6

When 4 anterior maxillary incisors are missing and the arch is ovoid:

a- 3 implants are place one in the central and 3 in the laterals
b- 2 implants are placed in the lateral incisors area
c- 2 implants are placed in the central incisors area
d- 4 implants should be placed

Answer 6

a- 3 implants are place one in the central and 3 in the laterals

Question 7

The dental arch form of the patient is determined by:

a- The shape of the residual ridge
b- The width of the residual ridge
c- The position of the upper lip
d- The final teeth position in the premaxilla

Answer 7

d- The final teeth position in the premaxilla

Question 8

To decrease stress complications it is more effective to:

a- Splint multiple implants
b- Use wide diameter implants
c- Use long implants
d- Use short implant

Answer 8

a- Splint multiple implants

Question 9

In patient with multiple missing posterior teeth when force factors are high:

a- Wide implants are recommended
b- Increasing the number of the implants is recommended
c- Long implant is recommended
d- Oblique implant is recommended

Answer 9

b- Increasing the number of the implants is recommended

Question 10

Two of the key implant positions for RP-4 maxillary IOD are in the:

a- Central incisor and the distal half of the first molar
b- Central incisor and the distal half of the second premolar
c- Bilateral canine and the mesial half of the first molar
d- Bilateral canine and the distal half of the first molar

Answer 10

d- Bilateral canine and the distal half of the first molar
