Osseointegration In Dental Implants

Osseointegration is a direct structural and functional connection between living bone and the surface of a load-bearing implant. As described in the uploaded document, the concept was first introduced by Brånemark in 1969, who defined it as a direct bone-to-implant contact without any intervening soft tissue layer. Later, the American Academy of Implant Dentistry (1986) emphasized the firm, asymptomatic, and immobile fixation of an alloplastic material within bone under functional loading. Zarb and Albrektsson further highlighted that clinically successful osseointegration implies a stable implant without pain, radiolucency, or mobility. The book also notes that osseointegration is influenced by several factors, including implant material (commonly commercially pure titanium), surface characteristics, surgical technique, bone quality and quantity, and loading conditions. Primary stability at placement and controlled healing are critical for successful bone formation at the implant interface. Overall, osseointegration forms the biological basis for the long-term success of dental implants.
