CATEGORY 72 AUSTRALASIAN DENTIST CLINICAL Orthodontics has advanced signi cantly from early xed appliances to today’s clear aligner systems, which o er patients a discreet and convenient alternative for smile correction. However, challenges remain – particularly around patient compliance, discomfort, and the biological impact of force application. Conventional single-thickness aligners can deliver relatively high, continuous forces, often leading to discomfort and potential risks to the periodontal ligament (PDL), including root resorption and unpredictable tooth movement. A dual-phase approach with TrioClear® TrioClear® is a ground-breaking design of clear aligners. Nearly invisible and meticulously custom-designed for each patient, these removable clear aligners address many of the common challenges with smile correction – for users and practitioners. TrioClear®’s key di erentiator is the innovative dual-aligner system, combining a soft and a hard aligner for each treatment step. With its TrioDim ForceTM Technology and fewer attachments, this approach initiates with a soft aligner, applying a gentle force to commence tooth movement. e sequence then transitions to a hard aligner, e ectively completing the movement with a more substantial force. is strategic combination allows teeth to move faster than other brands in the market – up to 0.6mm with TrioClear® compared to only 0.5mm with others. e TrioClear® system uses intermittent low forces to initiate a mild in ammation in the PDL, nudging the teeth into movement with minimal root resorption. A recent study found that forces in the range of 0.20-0.26N/cm2 strike the perfect balance, ensuring adequate blood supply and reducing the risk of cell damage1. As a bonus, this also minimises pain and discomfort for the patient. is case highlights the advantages of using progressive thickness aligners within TrioClear®’s Progressive Force Concept. By alternating soft and hard aligners, the system delivers controlled, staged forces that reduce peak force levels while maintaining a consistent load progression at each treatment step. is biologically balanced approach supports vascular integrity, minimises the risk of root resorption, and enables e cient tooth movement across a broader range -without extending overall treatment time compared to single-thickness aligner systems. Results to smile about A 24-year-old female patient presented with concerns about anterior crowding, overlapping of tooth 21, increased overjet, lower crowding, narrow arches, and a midline discrepancy. Her primary goal was to improve the overall aesthetics of her smile. Advancing clear aligner therapy: the TrioClear® approach Pre-Treatment
