Course overview

An easy way to start designing and manufacturing aligners on your own! A profitable treatment option for doctors and a more effective treatment process for patients.
The course is designed for:
– Beginners in orthodontics: you will learn the biomechanical aspects of aligners treatment and be able to design as well as manufacture aligners yourself at the very beginning of your career!
– Expert specialists in orthodontics: during the course you will be able to acquire numerous protocols and tips from the lecturer
– Prosthodontist: you will be able to treat mild forms of malocclusions yourself and prepare the patient for prosthetics
– Clinic Managers: you will explore all the equipment's needed to be purchased to begin manufacturing aligners and take your clinic to a whole new level!
