Introduction To Implant Supported Prosthesis Flashcards
Classification system for partial edentulism
Prosthetic Diagnostic Index Classification (PDI)
Class 1 to Class IV
What does class 1 represent
An uncomplicated clinical situation
What does class IV represent
A complex clinical situation
Diagnostic criteria for PDI classification
Location and extent of edentulous area
Condition of the abutment teeth
Occlusal scheme
Residual ridge
Class I
Ideal or minimally compromised
Class II
Moderately compromised
Class III
Substantially compromised
Class IV
Severely compromised
Why was research for implant rehabilitation of edentulous patients conducted in the mandible
Reduced denture bearing surface of the mandible
Mobility of the tongue, pts complained of instability of denture and an inability to adapt to removable prosthesis
T/F: pts are more likely to accommodate to a maxillary denture
True
What else is found with maxillary dentures?
Esthetics are satisfactory
Greater retention, support and stability
What do implants allow us to offer
Palate less maxillary prosthesis
What are one of the major decisions to make when restoring the edentulous maxillary or mandible with implants
Restored with either removable implant supported prosthesis or fixed implant supported prosthesis
Crown/FDP restorative space
5 mm - screw
7 mm- cement
Crown/FDP bucccal/lingual
2 mm buccal
1 mm lingual
Crown/FDP Mesial distal
3 mm implant
1.5-2 mm tooth
Locator restorative space

13 mm interfixutre for clip
Bar/locator restorative space
15 mm
Bar/locator buccal/linugal
2 mm buccal
1 mm lingual
Bar/locator mesial distal
3 mm between implant
Fixed complete denture restorative space
8-15 mm
Fixed complete denture buccal /lingual
2 mm buccal
1 mm lingual
Fixed complete denture mesial distal
3 mm between implant
What can we obtain support from with overdenture type designs?
Both implants and the mucosa
Splinted vs non splinted
Bar vs non splinted (removable implant supported prosthesis)
What are fixed restorations entirely supported with ?
Implants
Enough number of implants should be placed!
T/F: a fixed restoration should not be promised to a pt until all diagnostic criteria are evaluated
True
What are the diagnostic criteria for fixed restoration ?
Quality and quantity of bone for support
Lip line, lip support, and esthetic demands
Maxillary implant supported fixed prosthesis extra oral exam
Facial and lip support
Smile Line
Lip length
What is one of the best diagnostic tools
The patients existing denture
When there is a large discrepancy, what can facial and lip support be managed with ?
Flange of a removable prosthetics
FIXED IS NOT INDICATED
Low smile
Clinical crown exposure not greater than 75% and no gingival tissue
Medium smile
75-100% exposure of clinical crowns and interdental or interproximal papillae
High smile
Total exposure of clinical crowns
What will a pt with a short upper lip present with
Maxillary anterior teeth will be exposed in repose
What will pts with a long upper lip present with
Anterior teeth will be covered
Which is preferred long or short upper lip
Long upper lip
What is the anterior posterior spread
Measuremt of the distance from the center of the most anterior implant in the arch of the distal of the more posterior implant
Where shoudl the most posterior implant be inserted
As far distally as possible
What is the number of implants to be placed determined By
Quality of bone
Anticipated force to be placed on the restoratoin
Relationship between the shape of the residua ridge and the dental arch form
Dental square arch
6 implants
Ovoid dental arch
7 implants
Tapering arch
8 implants
Maxillary overdenture minimum implants
4
Mandibular overdenture minimum implants
2
Maxillary hybrid minimum implants
6
mandibular hybrid minimum implants
