Insertion torque/time integral as a measure of primary implant stability

The goal of this in vitro study was to determine the insertion torque/time integral for three implant systems. Bone level implants (n = 10; BLT – Straumann Bone Level Tapered 4.1 mm × 12 mm, V3 – MIS V3 3.9 mm × 11.5 mm, ASTRA – Dentsply-Sirona ASTRA TX 4.0 mm × 13 mm) were placed in polyurethane foam material consisting of a trabecular and a cortical layer applying protocols for medium quality bone. Besides measuring maximum insertion torque...
