"I have some specific questions that I'm hoping Dr. Wang could answer for me.

When doing PBR":

When doing PBR:

Bone Q1= immediate loading

Bone Q2= early loading

Bone Q2E= wait 4 months?

Bone Q3= wait 4 months?
Bone Q3E= progressive loading

Bone Q4= progressive loading 

1. Is each "Bone Quality" time above correct?

2. What does Dr. Wang mean by;

       "early loading"?

       "progressive loading”?

Q2 = Early Loading (less than 3 months)

Q2E = “Delayed” Loading (4~5 months) (Due to requirement of bone grafting)

Q3 = “Delayed” Loading (4~5 months) (No bone grafting, but formation of placement hole is possible with magic  expander)

Q3E = “Delayed” Loading (More than 8 months) (Due to very little cortical bone and lots of bone marrow space. Bone grafting is required)

Q4 = “Delayed” Loading (More than 8 months) (No cortical bone)

 “Early Loading” refers to the ability to successfully load within 3 months of placement. This is possible in a lot of cases with Q2 bone because the Magic Fin Thread maximizes the preservation of the patient’s original bone during placement. 

 “Progressive Loading” is the concept introduced by Dr. Karl Misch, in which the bone around the implant is loaded with progressively higher loads in order to strengthen the bone’s resistance to forces. Dr. Wang says that theoretically, Q2E~Q4 is supposed to be progressively loaded. And the concept of progressive loading is theoretically sound BUT completely impractical due to the fact that the oral habits of patients cannot be controlled by the clinician. Progressive loading’s success is contingent upon careful control of the patient’s oral and chewing habits. Thus, the concept of the IBS system is to maximize the preservation of the patient’s original bone because of the fact that original bone has much higher resistance to loads, and ultimately, a better initial loading capability of the bone.
