Abstract:
SmartTrackTM, created by Align Technologies, has a lower initial insertion force and a longer working range compared to the older EX30 material to aid orthodontic tooth movement (OTM). OBJECTIVES: To investigate the effect of SmartTrackTM on OTM in-vivo over a 25-day period compared to the EX30 material. METHODS: Aligners made of one of the two materials and programmed for 0.25mm of buccal movement of a maxillary incisor were used in 33 subjects (17 females and 16 males), 18-40 years old, for 22 hours/day for 25 days, in a randomized, blinded manner. Cone beam computed tomography (CBCT) imaging was conducted prior to tooth movement. RESULTS: SmartTrackTM achieved significantly higher mean OTM (73.1%) compared to EX30 (42.8%) by Day 14. No difference in OTM occurred from Day 14-25. Mixed modeling revealed SmartTrackTM and compliance separately provided 16% and 9% higher OTM. No difference between CBCT measurements and tooth movement was noted. CONCLUSION: SmartTrackTM achieved a higher mean OTM with a seemingly shorter lag phase compared to the EX30 material over a 25-day period. A combination of SmartTrackTM effects and compliance play a collective role in achievement optimal OTM.
