Prinzipielle Eigenschaften der durch Zahnimplantate im Kiefer erzeugten Spannungsverteilung
Abstract
Using the Finite Element Method some principal characteristics of the stress distribution caused by dental implants have been investigated in idealized plane cross-section models for the jaw. Two main loading directions for the implant, a pure vertical and a pure horizontal one, and different contact conditions in the interface between bone and implant, i.e. fixed connection or a good fit with pressure transferability alone, werde considered. It is shown that in the case of only good fitting and under vertical load the highest stresses are generated beneath the base of the implant in the spongy interior bone, whereas in all other cases the stress peaks arise in the cortical shell in that part where the implant passes through.
