Dental implant CAS with structural analysis
We have developed a dental implant planning and navigation
environment, which includes a method to predict implant stability
prior to surgery. This kind of quantitative information is required to
allow early loading and to maximise the chance of osseointegration and
long-term clinical success. The method utilises an in-house finite
element solver that has been integrated into our planning
system. Using this solver, fully automatic, patient-specific analysis
that predicts the load-carriage and micro-motion at the implant
interface is achieved in real-time. The results of laboratory
experiments showed that the predicted micro-motion correlates well
with experimental results. The additional knowledge offered by this
system may help optimising the placement of implants and avoiding
exploratory surgery.
