Introduction: The prevalence of lingual orthodontics has been increasing among the youth who prefer to undergo treatment with invisible appliances. The HIRO system is the most popular and widely accepted technique for lingual appliance bonding as it is economical. However, the great precision required for this system renders it highly technique sensitive. The final finish of the case depends, to a great extent, upon the accuracy and precision of each step involved in the HIRO system.
Methods: The present technique describes a novel procedure for lingual indirect bonding using HIRO system. The conventional HIRO system has been modified by integrating 3D scanning and rapid prototyping with treatment planning and virtual diagnostic set-up.
Result: This procedure makes the set-up more accurate for a better finish and saves a lot of laboratory time.
Conclusion: The hybrid HIRO is a cost effective method for patients who cannot afford a fully customized lingual appliance. It also opens a range of possibilities for the incorporation of 3D technology in routine clinical practice.
