not sure both answers were correct

b. Mandib overdenture need 2 implants

Something about screw retained vs cement

(i didnt understand question)

Definition of closed tray vs open tray

* Closed tray - should be used as a preliminary impression to facilitate fabrication of verification Jig and Open Tray copings * **Open Tray- more accurate** when multiple implants are connected, if possible connect impression copings

T/F do you take an xray after placing impression coping?

True

What resorbs first after extraction? a. Cementum b. Bundle bone c. Connective tissue

b. Bundle bone

T/F: Most people have thinner buccal bone than lingual bone

Yes

True/ False: CBCT less radiation than medical CT

True

TRUE/Fasle: CBCT better soft tissue imaging than medical CT

False

a. Pano

If xray shows non-seating of impression coping what do you do? a. Tell the lab and they will compensate b. Leave it, doesnt matter c. Reposition and reseat until fully seated

c. Reposition and reseat until fully seated

All are true of TISPs except: a. Definite cementation b. Short span bridge c. Stress breaking connectors d. Avoid telescopic crowns | Tooth-Implant Supported FPD

c. Stress breaking connectors (CANNOT HAVE STRESS BREAKERS NEEDS TO BE RIGIDLY CONNECTED TO TOOTH AND IMPLANT)
