Paper nr Hypothesis Position Analysis Answer
I Does the effect of the bisphosphonate coating increase over time?
Cortical &
cancellous Pullout strength Yes II Is the bisphosphonate coating
technique applicable on titanium screws?
Cancellous Pullout strength Yes
II What is the release profile of
the coated bisphosphonate? PBS solution measurement Scintillation 60 % released within 8 h III Why was the effect of the
bisphosphonate coating increased over time?
Cortical Histomorphometry Formation of a bone “nut” III Does the bisphosphonate
coating increase the removal torque at 2 weeks?
Cancellous Removal torque Yes
IV Does the bisphosphonate coating increase the mechanical fixation in ovariectomized rats too?
Cancellous, ovx
& sham Pullout strength Yes
