Abstract
Immediate and early loading of dental implants reduces treatment time and enhances patient satisfaction, but success depends on achieving sufficient primary stability and early osseointegration. This clinical trial compared implant stability parameters for guiding loading protocols in 40 patients requiring single posterior mandibular implants. Resonance Frequency Analysis (ISQ), Periotest values (PTV) and insertion torque were recorded at placement and re-evaluated at 3 weeks and 3 months, alongside radiographic bone loss assessment. Both groups showed progressive ISQ improvement and minimal marginal bone loss, with no significant differences between immediate and early loading. Thus, we show that ISQ and insertion torque are reliable indicators for safe loading decisions in implant therapy.
