Implant Restorative Options for Edentulous Patients

Question 1

Implant Restorative Options:

Uses Locator Attachments

• Recommended # of implants
• 4 on the maxilla * 2 on the mandible

Answer 1

Implant Retained – Tissue Supported

overdenture

Question 2

with a Implant Retained – Tissue Supported is the following statement t/f:

In the event the maxilla is dentate and the mandible is edentulous, it is recommended to have 4 implants placed on the mandible to avoid excessive resorption of the posterior mandibular ridge.

Answer 2

true

Question 3

When doing a CBCT for denture fabrication, how many are taken?

Answer 3

2 one with pt and denture in, then one with just the denture

Question 4

Which fixed prosthesis is described?

For components, the absolute minimal vertical space requirement is 7 mm:

• 2 mm height of locator
• 2.5 mm height of metal housing
• 2.5 mm acrylic thickness

Answer 4

overdenture

Question 5

FOr an overdenture, The minimum needed horizontal space, which is assessed apical to the most inferior aspect of the prosthetic tooth, needs to be approximately ____ mm .

Answer 5

10 mm

Question 6

\_\_\_\_\_\_\_  suggests that
ideally, 10 mm is needed in both
vertical and horizontal
dimensions to offer enough
Jo urnal of Prosthetic Dentistry 2006 95, 102-105
required restorative space

Answer 6

10 by 10 guideline

Question 7

t/f: 
Locator abutment selection
* Measure tissue height from implant
platform
* Highest point determines abutment height
* Round UP to closest abutment height,
never down

Answer 7

true

Question 8

Which fixed prosthesis is described?

• Usually utilizes 4-6 implants connected by a bar
• Cost of the bar ($2500 to $4000) * Retained by Hader clips or locators * Supported by the bar and soft tissue

Answer 8

implant retained / implant supported

Question 9

Implant supported detnures:

t.f: * A bar SHOULDN’T be cantilevered off
the most distal implant MORE THAN 1.5
times the A-P distance of the implants.

Answer 9

true

Question 10

• Do NOT exceed 1.5 times the A-P distance of the implants for cantilevers.
• __mm should be the maximum length of the cantilever regardless of the A-P spread.

Answer 10

18 mm

Question 11

t/f: For bar retained denture: implant retained, implant supported

For components, the absolute minimal vertical space requirement is 11 mm: 
- 2 mm soft tissue around the
abutment 
- 1 mm soft tissue under the bar 
- 5 mm for the bar and attachment 
- 2.5/3 mm acrylic thickness

Answer 11

true

Question 12

Which prosthesis?

• Most like natural teeth
• Excellent chewing efficiency and bite force
• Stronger than removable appliances
  * Acrylic resin vs. metal and porcelain
• Decreased gagging and speech issues

Answer 12

fixed implant prostheses

Question 13

how many implants per arch for fixed implant procesthesis?

Answer 13

6-8 per arch

Question 14

_____ ____ impression technique for final fixed implant prosthesis - more accurate when multiple implants are connected, if possible connect impression copings

Answer 14

open tray

Question 15

____ ____ ____: Utilizes fewer implants (4) to retain and support a hybrid appliance when inadequate bone height is present in the posterior quadrants.

Answer 15

all on four

Question 16

What are the benefits of the all on four technique for the maxillary arch?

Answer 16

avoid the sinus by angulation of implants

angle reduced posterior cantelever

Question 17

What two steps may be taken to achieve an abutment-level hybrid prosthesis that requires at least 15 mm of vertical restorative space.

Answer 17

alveoplasty and an increase in VDO
