Lasers in Dentistry

Dentistry is constantly evolving, and as a modern dental practitioner, it is essential to stay up-todate with the latest techniques and technologies. One such technology that has revolutionised the field of dentistry is the use of lasers, which have been used in dentistry for over 30 years and have proven to be a highly effective and safe tool for a wide range of dental procedures.

University Mastership Advanced Module Courses

  • Benefit from Certified Education in Lasers in Dentistry
  • From Modules to Optional Mastership Upgrade

In standard academic studies in dentistry, dentists do not get to learn about dental laser technology and treatment concepts. Building onto a university degree in dentistry, the necessary professional knowledge for laser applications in dental practice is taught at the highest academic level in theoretical lectures and practical teaching for two selected wavelength areas - dental Erbium lasers and dental diode lasers.

Relevant theories and application options (such as with each Module Course below) pertaining to laser use in dentistry, are taught for those wavelengths. Participants obtain sound theoretical knowledge in lectures and seminars led by renowned, competent and experienced international scientists and practitioners. Skills training sessions, exercises, practical applications, and live operations guide participants towards using lasers successfully and professionally.

Mastership Advanced Modules give you the chance to dive deeper into your chosen laser module only, or multiple modules!

Laser Safety Officer Course [LSO] 

1 Day, 1 ECT

Prerequisite / Foundational course before any module

You only need to do LSO once and your credits will be recorded, should you want to do additional modules thereafter, with no time limit.

Various Advanced Module Courses

2 Days, 2 ECTS

Complete one, or two or three or all. By completing at least 3, you qualify for the Mastership Exam in Vienna, Austria. No time limit.

  • Lasers in Endodontics
  • Lasers in Periodontics
  • Lasers in Dental Aesthetics
  • Lasers in Orthodontics, 2 Days
  • Lasers in Photobiomodulation [PBMT / LLLT]
  • Lasers in Pediatric Dentistry
  • Lasers in Facial Aesthetics

The Laser Safety Officer Course [LSO] is the basic start before participating in any other module. 

You can do the LSO course only, or you can do LSO with a module.

If you complete LSO and follow it up with any 3 Mastership Module Courses, you will qualify for the final examination module at Vienna's Sigmund Freud University, where you will enjoy a recap lecture day with Dr Rene Franzen, present your 5 clinical cases and complete the written exam to graduate with a Mastership in Laser Dentistry.

This flexible structure is ideal for Specialists or Dentists wanting to dive deeper into lasers in certain treatment areas only. 



We kick things off with LSO + Endo Module!

After many requests from not only Endodontists, but also dentists who are challenged on a daily basis to perform root canal treatments with acceptable outcomes and a simple technique. The statistics / high failure rate of root canals is simply not acceptable when this technology exists. Read more below and join us!
