Implant Restorative Options for Edentulous Patients Flashcards
Implant Restorative Options:
Uses Locator Attachments
- Recommended # of implants
- 4 on the maxilla * 2 on the mandible
Implant Retained – Tissue Supported
overdenture
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.
true
When doing a CBCT for denture fabrication, how many are taken?
2 one with pt and denture in, then one with just the denture
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
overdenture
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 .
10 mm
\_\_\_\_\_\_\_ 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
10 by 10 guideline
t/f: Locator abutment selection * Measure tissue height from implant platform * Highest point determines abutment height * Round UP to closest abutment height, never down
true
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
implant retained / implant supported
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.
true
- 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.
18 mm
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
true
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
fixed implant prostheses
how many implants per arch for fixed implant procesthesis?
6-8 per arch
_____ ____ impression technique for final fixed implant prosthesis - more accurate when multiple implants are connected, if possible connect impression copings
open tray
____ ____ ____: Utilizes fewer implants (4) to retain and support a hybrid appliance when inadequate bone height is present in the posterior quadrants.
all on four
What are the benefits of the all on four technique for the maxillary arch?
avoid the sinus by angulation of implants
angle reduced posterior cantelever
What two steps may be taken to achieve an abutment-level hybrid prosthesis that requires at least 15 mm of vertical restorative space.
alveoplasty and an increase in VDO
