[Immediate implantation and the role of early functional loading of the implant]

Experimental morphologic study was performed on lab mini-pigs (biological model) to determine optimal time for functional loading in intraosseous implantation (1, 3, 6.5 months). Morphologically, connective tissue capsule developed around the implant within 1 to 6.5 months. It quickly matured, condensed and thinned due to reparative osteogenesis. It was also observed that the bone mass grew on the implant surface and alveolar process changed equivalent to functional loads. Prevalence of connective tissue or supporting structures in implant/bone tissue zone depended mainly upon anatomical-topographical conditions in the oral cavity and achievement of primary stabilization.
