Correct answer: E — Chemical bonding of the implant to bone

Primary stability is the mechanical anchorage of the implant in bone immediately at placement, achieved through friction fit (press-fit) between the implant body and the prepared osteotomy site. It depends on bone density, implant design (threads, taper), and surgical technique. Primary stability is essential for osseointegration to occur. Osseointegration (direct bone-to-implant contact at the light microscopic level) is secondary (biological) stability that develops over 3-6 months.
