Q

Why was research for implant rehabilitation of edentulous patients conducted in the mandible

A

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

34
Q

What are fixed restorations entirely supported with ?

A

Implants
Enough number of implants should be placed!

35
Q

T/F: a fixed restoration should not be promised to a pt until all diagnostic criteria are evaluated

A

True

36
Q

What are the diagnostic criteria for fixed restoration ?

A

Quality and quantity of bone for support
Lip line, lip support, and esthetic demands

37
Q

Maxillary implant supported fixed prosthesis extra oral exam

A

Facial and lip support
Smile Line
Lip length

38
Q

What is one of the best diagnostic tools

A

The patients existing denture

Q

When there is a large discrepancy, what can facial and lip support be managed with ?

A

Flange of a removable prosthetics
FIXED IS NOT INDICATED

40
Q

Low smile
