Revolutionary 1st in the world Non-Ligating Bracket System

Revolutionary 1st in the world - Non Ligating bracket system

Project Development with SIMTech

The idea of a non-ligating bracket system first started in 2010 when Innobrace  Orthodontics wanted to create a novel approach that uses a unique flexible engagement system to hold the arch wire in place unlike any commercially available bracket system, This novel design is specially  designed to save time for orthodontists, yield better treatment efficiency and comfort for the patients.


In 2010, Dr. Atsushi Danno, a PE-COI (Precision Engineering Centre of Innovation) Senior Consultant of Singapore Institute of Manufacturing Technology (SIMTech) - a research institute of the Agency for Science, Technology and Research (A*STAR) - introduced a special titanium alloy to Innobrace for the flexible engagement system of the bracket. The special titanium alloy with low elastic modulus and good mechanical properties were found suitable for the flexing concept in the novel non-ligating bracket design. This started the feasibility study to assess the forming process of the special titanium alloy non-ligating brackets.


With the support of A*STAR's "Get-Up Program", three SIMTech staff were attached to Innobrace full-time to assist the company to work on developing this new innovative non-ligating bracket system. After the successful completion of the Phase 1 project, the innovation and commercialisation value was recognised by SPRING Singapore and the Capability Development Grant (CDG) was awarded to Innobrace Orthodontics Pte Ltd in 2011 to continue the collaboration with SIMTech to pursue the commercialisation of the NLB system.


SIMTech provided technical know-how and consultation to Innobrace through simulation, design and process development. With the simulation data, Innobrace as able to modify and improve further on the design of the NLB system. The final design of the NLB was finalised in 2012 and SIMTech continues to assist Innobrace in establishing manufacturing processes and transferring technical know-how for commercialisation.


Our commitment to pursue product excellence and innovation depends on feedback from the industry. We are grateful to all the doctors who have given us their valuable input and would like to thank all individuals and the SIMTech team who have contributed to this project and made this journey possible.
