Abstract
An appliance was designed to increase the cortical bone surface contact area of miniscrew implants (MSIs). The purpose of this
A total of 48 MSIs were placed into bone specimens prepared from the ilium of bovines. Half were placed with the newly designed apparatus and half were placed conventionally. All the specimens were subjected to tangential force loading perpendicular to the MSI with lateral displacement of 0.6 mm, using an Instron Universal Testing machine. The maximum removal torque of each tested specimen was also recorded. Both study and control groups were divided into two subgroups based on whether they had thin and thick cortical bone.
The test group had statistically higher force anchorage resistance and maximum insertion torque values than the control group (
