Endosseous dental implants have become a significant factor in prosthodontics and restorative dentistry since the early 1970s. The concept of osseointegrated titanium implants pioneered by BRANEMARK in the 1970s and subsequently developed to provide viable and predictable long term replacement of natural teeth has become a major treatment option.Osseointegration is defined as the "direct structural and functional connection between ordered, living bone and the surface of a load carrying implant. Creation and maintenance of osseointegration , therefore, depends on the understanding of the tissue's healing, repair, and remodeling capacities.Successful implant treatment planning requires a good understanding of the biomechanics, an appropriate assessement of the load bearing capacity, & an adequate engineering plan to maintain ossteointegration with resistance to the anticipated occlusal loads.
