4D shape-shifting aligners: A new dimension of orthodontics achieving high-quality results and increasing patient compliance in the daily routine


The 4D technology and shape-changing aligners are still unknown to most of us; however, they represent a way not only to reduce the number of aligners used in a single treatment but also to minimize plastic waste during production. Utilizing a specific device that activates the aligner's memory to transform its shape into a new one is a groundbreaking concept for the clear aligner industry. Moreover, it serves as a definitive stride toward the future of orthodontics. Transitioning orthodontics to 4D technology will promote well-being for professionals, patients, and, above all, our planet, making it the next logical and intelligent progression in orthodontics.
