Corrosion and fatigue - Biomechanical mechanisms of failure in implant treatment

Analysis of mechanical failure of implants, suprastructures and prostheses often point to fatigue failure and corrosion fatigue. The presentation will review typical bite forces and how they can lead to initiation of fatigue failure in various restorative materials. Being aware of these factors will help practitioners minimise or avoid them in treatment planning.

Neil Waddell has been a Dental Technician since 1980 and has worked in Rhodesia, South Africa, Australia and New Zealand. He holds a Doctor of Philosophy (University of Otago) Master’s Diploma in Dental Technology (Technikon Natal), Postgraduate Diploma in Clinical Dental Technology (University of Otago), and a Higher Diploma in Education (University of Natal).

 He has lectured internationally on a wide variety of subjects in dental technology and dental materials during the past 25 years and during this time, developed specialist expertise in the areas of implant overdentures, dental materials, maxillofacial and ocular prosthetics and crown and bridge ceramic restorations.

 Neil conducts experimental and observational research in; Dental materials, toughening of advanced ceramics; Cranio-facial biomechanics, prosthodontic failure mechanisms and adhesion of dental restorations and materials; Sub-concussive brain injury research, in vitro modelling of the effects of blunt force trauma to the head and accumulative damage to the brain; Forensic biology, in vitro modelling of blunt force trauma, forensic odontology, wounding and ballistic blood splatter analysis and development of simulant materials for forensic modelling.

 Neil has 107 peer reviewed publications, 2 book chapters and 86 conference proceedings. He is currently the Head of Biomaterials in the Faculty of Dentistry, University of Otago.
