1
Q

If a two stage sinus graft is done, what is the timing for implant placement?

What determines whether immediate loading can be done?

A

4 months after grafting

Amount of primary stability

2
Q

What is the moa of clopidogrel?

How long before surgery should it be discontinued?

A

Binds to ADP receptors on platelets preventing adhesion and aggregation.

Should be D/C’d 5 days prior

3
Q

What is the moa of aspirin?

Why is low dose aspirin used instead of high dose?

A

Irreversibly binds to the platelet dependent COX preventing platelet aggregation for the life of the platelet.

ASA favors COX 1, so high doses can inhibit endothelial prostacyclin preventing vasodilation and may worsen ischemia

4
Q

Do you need to stop low dose ASA prior to minor elective surgery?

A

No

5
Q

What is the minimum interarch space required for the restorative stack?

A

5mm

6
Q

What is the magnification of a panoramic radiograph?

How do you compensate?

A

25%

Increase the implant tracing template size by 25%

7
Q

Which labs would you order to evaluate a pt for hyperlipidemia / atherosclerotis related cardio and cerebrovascular risk?

A

Total body cholesterol
LDL
HDL
triglycerides

8
Q

What total cholesterol level reflects a low risk for MI in absence of other factors?

A
9
Q

What is normal LDL range?

A

70-130mg/dl

10
Q

What is normal HDL levels?

A

40-60mg/dl

11
Q

What is normal triglyceride levels?

A

10-150mg/dl

12
Q
Although research shows good outcomes from immediate healing cap placement and loading, fewer problems arise from submerged and unloaded implants. 
How long before uncovering:
In the mandible?
In the maxilla?
In grafts?
A

4 months
6 months
6 months

13
Q

Which implants have highest fail rates in posterior maxilla?

Which have lowest fail rates?

A

Short

Wide

14
Q

What is the amount of bone in the sinus area that determines whether an open or closed, single or two stage sinus graft is needed? Why

A

5mm is the minimum amount of bone required for implant stability
