Abstract
This study is a comparison and examination of the stress distribution of the bone tissues surrounding the fixture under a static vertical load condition with regard to an osseointegrated implant bridge (OIB) applied to the lower molar region. It was performed by constructing more than one of two-dimensional finite element models that differ in design conditions. In the case of the bounded type OIB design to the fixture placed in a straight line, a decrease in the maximum stress value of the compact bone surrounding the fixture was recognized with a decrease in the total inter-fixture distance and an increase in the number of placed fixtures. On the other hand, in the case of the free-end type OIB design, there is an increase in the maximum stress value compared with the bounded type OIB design and, in particular, a marked increase with the decrease in the total inter-fixture distance and the extension of the free-end pontic. However, the effect of the number of fixtures placed on the maximum stress value of the surrounding bone tissues was considered to be comparatively small.
