Design outcomes

Primary

MeasureTime frame
Dental implants primary stability is assessed using Insertion Torque (IT) and Implant Stability Quotient (ISQ) measurements after implant placement.

Secondary

MeasureTime frame
Dental implants secondary stability and its progression is asssessed using Implant Stability Quotient (ISQ) at 15, 30, 45 and 60 days.
