Biomechanics and oral implantology

Programme directors: 

Associate Professor Neil Waddell (Dental biomechanics and biomaterials) 
Professor Warwick Duncan (Oral implantology)

Our work has three main areas of focus, namely dental biomaterials, biomechanics and oral implantology.

Dental biomaterials and biomechanics

Led by Associate Professor Neil Waddell, our group carries out experimental and observational research in oral biomechanics, with a special focus on prosthodontics (failure mechanisms and adhesion of dental restorations and materials). Members of the group also contribute to other areas of research such as forensic science (in vitro modelling of blunt force trauma, forensic odontology, wounding and ballistic blood splatter analysis) and intra-oral pressure dynamics. Our achievements in research into artificial saliva, dental hard tissue anatomy, intra-oral pressures during swallowing, orthodontics, paediatric dentistry and also forensic biology have gained international recognition. The eventual goal of the innovative application of biomechanical analyses to problems in dentistry and forensic biology is the development of a new understanding of underlying structure and function that will lead to clinical translation of our results.

Research carried out by this group includes:

  • Dental materials – development of new dental restorative materials for dental CAD/CAM systems.
  • Silver and gold nanomaterial technology – developing nanoparticles for use in a range of therapeutic technologies and toughening of advanced ceramics.
  • Oral 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 on accumulative damage to the brain.
  • Dental hard tissues and evolutionary oral biology – using animal teeth to gather a wide range of information about the biology, evolution and interactions with the environment of fossil and recent species.
  • Forensic biology – in vitro modelling of blunt force trauma, forensic odontology, wounding and ballistic blood splatter analysis, development of simulant materials for forensic modelling.
  • Communication of forensic concepts to the general public

Implantology and associated superstructures

Our Oral Implantology group, led by Professor Warwick Duncan, have expertise in conducting clinical (human) and preclinical (animal) trials and laboratory-based research relating to oral implants.

The aim of this research is to develop evidence-based treatments that reduce the interval between oral implant placement and loading. This is achieved by optimising the implant design and the surgical and prosthodontic protocols and materials. Research is being conducted into different oral implant systems, materials, surfaces, superstructures, and surgical and restorative protocols, as well as supporting biological and regenerative products.

Graduate student research includes immediate placement and/or loading of single implants and implant-supported over-dentures, fit of zirconia prostheses, implant analysis using micro-CT, and analysis of different implant systems and bone placement grafts in sheep femur and maxillary sinus models.

Within the area of oral implantology our research focuses on:

  • Bone replacement grafting
  • Stem-cell regenerative therapies
  • Early diagnosis and treatment of peri-implant immune-inflammatory disease
  • Fit of aftermarket versus original equipment manufacturer (OEM) implant components
  • Modifications to dental implant materials and surfaces to enhance osseointegration
  • The effects of implant xture corrosion products on periodontal structures
  • In vitro modelling of masticatory forces on implant overdentures, their supporting sub-structures and surrounding bone
  • The short-term and long-term clinical outcomes of modified surgical and prosthodontic loading protocols during implant treatment
