Our Conference Speakers


22nd    10:40 – 11:40am

Digital Dentistry 2017

Today CAD/CAM is one of the fastest growing areas in Dentistry. It is essential to understand Digital technologies as well as the choices on materials available.

  • Insight on current CAD/CAM solutions for dental professionals

22nd  3:40 – 4:40pm

Design of CAD/CAM restorations

The utilization of the digital technology will only enhance the close cooperation and working relationship of the Dentist/Technician team. The evolution from Hand design to Digital design and the application of Diagnostic smile design previews, along with provisional restorations, and the possibility to practically manufacture replicas which serve as an base to create the definite all-ceramic restorations

  • Collection of diagnostic data
  • Significant reference lines
  • Esthetic form/smile principles
  • Treatment plan / Provisionals

23rd  9:00 – 10:00am.

The art & science of CAD/CAM restorations

The overall success and esthetic result does depend very much on profound skills related to mechanical and optical characteristics of available CAD/CAM materials and suitable fabrication and characterization techniques, which will be addressed in the presentation.

  • Mechanical & optical characteristics of Materials
  • Selection of Material correlated to case situation

Presentation – Movement into the digital era.

With the movement into the digital era, especially with removable prosthetics that Georges will be able to help NZIDT members come to terms with the transition, the current environment and where to from here from a manufacturer and developers point of view.


  • Georges has been involved in Dentistry since 1986.
  • In 2003 he studied G code to learn how to develop milling programs for materials using industrial milling machines.  This led to developments in Australia’s first CAM Zirconia system that developed into the company, Stoneglass Industries.
  • From then on developments in software design lead to the first full digital CAD/CAM occlusal splint system worldwide, in 2009, the BiiBCAD software for Implant Hybrid bridges.
  • In 2014 he worked closely with Adelaide and Sydney University Prosthodontic Students to finalize their full implant cases using the PDC CAD/CAM software.
  • In 2015 Georges introduced the PDC software and CAD/CAM learning into the Prosthodontic Syllabus at Sydney University. He is also in a teaching partnership with Columbia School of Dental Medicine in the United States, in which he works closely with Post Graduate students using Digital work flows for solutions for full arch tissue supported and implant fixed prosthodontics. As recently as this year the PDC digital software has also been implemented into Rutgers University School of Medicine and he is now working with Boston University in the United States.

John Batchelor has been involved in dental technology since 1979. His company Duchenne Dental Services is situated in Christchurch, New Zealand employing a team of 25 in the areas of clinical dental technology, orthodontics and prosthetics. He has lectured in Australia and New Zealand. A fundamental philosophy of Duchenne Dental Service is to keep up with trends and technology ‘s along with passing gained knowledge on via their teaching facilities. He is married to an orthodontist and has two children. Over the past six years he has been watching the trend of the digital age on dental technology while integrating the digital work flow into their orthodontic and prosthetic practices.

Presentation – Sustainable marketing strategies and proactive promotion as well as the role of social media as a promotion tool.

In this talk, I will argue for a change in our mindset first, before recommending social media for communicating brand and health messages. Drawing on my work in the area of public health and brand communication, I will show the need for such a change in mindset. Following which a theoretical framework and the skill-set required for using social media in communication will be presented.

Dr Mathew Parackal teaches Digital Marketing in the Department of Marketing. His research focuses on the quality of big data. In particular, he is interested in the scientific veracity and value of big datasets generated from social media and online sources. By upholding these two qualities, big data can be mined to answer interesting research questions and inform new product development. His work so far has been in the area of public health and development of online tools for marketing analytics.

Presentation – A longitudinal study of tooth loss & oral rehabilitation

Tooth loss reflects an individual’s poor oral health and lack of access to dental care. Replacement of missing teeth reflects the converse. Using data from the Dunedin Multidisciplinary Health & Development Study, this presentation will discuss the epidemiology of tooth loss and tooth replacement, and how these factors affect oral health-related quality of life.

Prof Broadbent is a Dental Public Health specialist working in Preventive & Restorative Dentistry at the Faculty of Dentistry. He helps run & teach parts of the Bachelor of Dental Surgery course. He conducts research with the Dunedin Multidisciplinary Health & Development Study and has an interest in investigating patterns of dental decay over time, social inequalities in dental health, and dentistry in general.

Presentation – Immediate Dentures. Not just ‘teeth to go’

Immediate dentures can provide some of your most rewarding moments as a clinician/ dental technician… They can also be the cause of your greatest headaches!

In this lecture we will look at steps you can take to minimise the fall out as you run the gauntlet of the immediate denture process.

Presentation – Changing workflows in prosthodontics and the importance of technical and clinical relationships

Suzanne’s presentation will explore changing workflows in prosthodontics and the importance of technical and clinical relationships.


Suzanne Hanlin started her career in Dentistry with a BDS in 1978 and a MDS in 1989, at the University of Otago. She received her FRACDS and MRACDS (Pros) from the Royal Australian College of Dental Surgeons in 1992 and 2009 respectively. In 2013, she received a PGDipHealInf from the University of Otago. She currently works as a Senior Lecturer in Prosthodontics, within the University of Otago, and as the (joint) – Clinical Associate Dean.

Her research interests are in practice based research, implant dentistry and education in prosthodontics.

Presentation – Sterilisation and Infection Control


Teaching microbiology to students, pursuing disciplines in which microbiology is not a central consideration, (e.g. dental and dental technology students) is a challenge for a microbiologist. Nevertheless, a component of microbiology is essential to support the principles of cross-infection control in facilitating safe and confident clinical and laboratory practises. Microbiology for Dental Technology, taught at the University of Otago, is informed and directed by the DCNZ Practice Standards.

This presentation will highlight some of the issues and principles of cross-infection control, and discuss research undertaken by BDS undergraduate students to communicate that effective cross-infection is compromised by time pressures. Undoubtedly, repeated reminders will enhance compliance and this may apply also to dental technologists, especially those removed from the clinic. This presentation, it is hoped, will serve to reinforce the need for continuous attention and re-evaluation of cross-infection control protocols in the dental technology laboratory.


Geoffrey obtained a BSc (Physiology) from the University of Otago in 1977 and a Postgraduate Diploma in Science (Microbiology) in 1980. He obtained his Ph.D. (Microbiology) at the University of Otago in 1986. Between 1986 and 1990, Geoffrey worked as a Post-Doctoral Research Fellow at the University of Minnesota, (USA).
