Prediction of mandibular bone remodelling induced by fixed partial dentures.
Fixed partial dentures (FPD) or dental bridges have been extensively utilised in prosthodontic restoration. Despite considerable clinical success to date, there has been limited fundamental understanding of the biomechanical consequences induced by FPD treatment. It is noted that FPD construction significantly alters the biological and mechanical environment in the supporting bone region. Thus, the surrounding bones will be engaged to adapt to such a biomechanical change. This paper aims to address this critical issue by developing a new remodelling procedure induced by FPD restoration. Specifically, it relates the mechanical stimulus to the change in Hounsfield Unit (HU) value in terms of surface area density (SAD) of bony morphology, which allows direct correlation to clinical computerised tomography (CT) data. The procedure will provide prosthodontist with a new approach for assessing FPD treatment, thereby optimising FPD design for improving longevity and reliability of future FPD restoration.
