Abstract [sv]

Osseointegrated titanium implants have become a commonly used method in edentulous jaws and today there are success rates in the magnitude of 82 % in the lower jaw and 98 % in the upper. During first year after implantation a fully normal marginal bone loss of 1-2 mm occurs. If the bone loss continues there is a risk of implant failure. High tensions in bone and inflammation caused by bacteria are possible reasons for this problem. It has been shown that a leakage of bacterias occurs between the parts of the implant and there are theories that this has effects on the marginal bone loss.

The aim of this thesis has been to increase the knowledge about microbial leakage with help of in vitro tests and virtual simulations. The goal was to create a test method to measure differences of microbial leakage in two implant systems.

The developed test method includes an in vitro test of six implants and Finite Element Analysis. The test method is the product of a process with several small tests. The final test method measures leakage of a coloured fluid with a spectrophotometer. The results are then compared with the virtual simulations to draw conclusions and find explanations how the implants are functioning.

The result of test on six implants, four Ospol and two Nobel Replace, indicates that there are differences in the magnitude of microleakage in different implant systems in due to the implant-abutment interface. No conclusions can be drawn before the test method is refined and more implants are tested.
