Truline clear aligners was established in 1988 and similar to other clear aligner systems such as Invisalign. Truline Dental is an Austalian-based company that makes aligners locally. One of their key features is that they are designed to offer more built-in movement per aligner. What this means is that if you wear the each aligner for the recommended amount of time per day for 2 weeks, then there will be more movement of your teeth.
