Dental implants generally fail as a consequence of bone loss in a peri-implant area. It is usually begins in the crestal bone and propagates towards the implant apex. 0,2mm mean annual bone loss owas recommended as one of the criteria for implant success.
Due to gradual bone loss, implants cannot withstand functional force without bone overload. In turn, it provokes complementary bone loss.
This fact singificantly influences long term success of dental implants. The aim of this study was evaluate and compare load-carrying abilities of different-size completely and partially osseointegrated implants to confirm long term implant success.
