Dental Devices

9:00-10:15 am CDT, June 30, 2020
No Registration Required

Session Abstract:

Covered in this session are dental devices that include diagnostic tools for dental caries, prostheses for maxillofacial defects and a novel device for root canal cleaning. The challenges involved in the design, manufacture and application of these devices will be discussed. All the presenters are key-opinion leaders in dentistry.

Dr. Wee obtained his dental degree from at Creighton University, his M.S. degree in the specialty of Prosthodontics at the University of Iowa and a Clinical Fellow in Maxillofacial Prosthetics Fellowship at the University of Pittsburgh Medical Center. While on full-time faculty, he completed his M.P.H. and Ph.D. degrees. He joined the University of Minnesota in Sept 2019.

 

 

Hooi Pin ChewHooi Pin Chew, Associate Professor, MDRCBB, University of Minnesota
Dr Chew is currently an Associate Professor with the Division of Biomaterials in the School of Dentistry at the University of Minnesota. She obtained her Bachelor of Dental Surgery from the University of Malaya and later obtained her clinical Fellowship in Restorative Dentistry (FDSRCS) from the Royal College of Surgeon, England. Her doctorate from the University of Manchester, UK is in diagnostics of dental erosion.

Her research interests are driven by her clinical practice and teaching and hence the nature of her work is a combination of laboratory and translational research. The two main impetus for her research are firstly to generate knowledge to shift the current practice of ‘reactive dentistry’ to a more ‘proactive’ one, i.e. a more preventive-oriented one; and secondly to develop objective, sensitive and quantitative assessment techniques for biomaterial clinical trials in order to reduce the need for large sample size and produce faster and more robust results. For these, she has worked extensively with optical methods such as optical coherence tomography, and recently along with machine learning to exploit its ability in deciphering the troves of insights obscured in big data.

Mehrzad KhakpourMehrzad Khakpour, Sonendo, Inc.
Dr. Mehrzad Khakpour was born and raised in Tehran, Iran where he graduated with a Bachelor of Science degree from the Sharif University of Technology. He then moved to the United States where he earned his Master of Science degree, and PhD in Mechanical Engineering from the University of Minnesota and the University of California, respectively. His graduate programs areas of study and research included turbulent reacting flows, cardiovascular fluid dynamics, and mathematical modeling of atherosclerosis using the theory of porous media. Dr. Khakpour joined Sonendo, Inc. in 2008 where he developed the GentleWave Technology, and currently serves as the vice president of research and development.


Presentation Abstracts:

"Facial Silicone Prostheses - Current Status and Concerns"
This presentation provides an overview of the role of the maxillofacial prosthodontist and elaborates on rehabilitation using facial prosthetics. Facial prostheses for the rehabilitation of auricular, nasal and orbital deficits that are retained by either adhesive or craniofacial implants will be presented. The limitations of these silicone facial prostheses will be detailed, and conceptual solutions will be suggested.

"Clinical Assessment of Dental Demineralization"
The current body of evidence regarding the progression and arrest of dental caries has made its early detection, risk assessment, and minimally invasive management the standard of care today. Hence, its diagnosis should ideally comprise of both detection and severity measurement in the form of lesion depth, demineralization severity, and mineral density distribution. A combination of this information is essential for clinicians to make informed decisions about the management of the disease process. To address the above needs, routine visual assessment will need to be supplemented by another quantification-enabled clinical detection device that demonstrates reasonably high sensitivity and specificity. Current evidences seem to indicate that photothermal radiometry, near-infrared transillumination, and optical coherence tomography are systems that had demonstrated such qualities. However, only optical coherence tomography is able to determine lesion depth and demineralization severity and mineral density distribution.

"Saving Teeth through Sound Science"
Technology is moving at a faster pace now than ever before, and the rapid adoption of technological advancements in the medical field is resulting in improvements in human longevity and quality of life. In recent years, the specialty of endodontics has struggled to keep pace with the growth of several other segments within the dental market, e.g. implant dentistry, which have benefitted from development of new technologies. The GentleWave System is a transformative technology and the result of more than a decade of investment in research and development intended to serve the endodontist in their pursuit to save teeth for patients in need of root canal therapy. In this presentation of the GentleWave System, Mehrzad Khakpour, PhD will review the fundamental principles of the mechanism of action and the procedure, as well as the efficacy and efficiency milestones achieved through extensive research and development. The presentation will also attempt to address some of the frequently asked questions.
