Faster treatment times: With traditional aligners, you typically switch to a new aligner every few weeks. 4D aligners, in theory, could be programmed to deliver forces in a way that reduces the number of aligners needed.
More comfortable wear: The constant pressure of traditional aligners can cause discomfort. 4D aligners, with their shape-memory properties, could potentially provide a more gentle and comfortable experience.
Reduced cost: Fewer aligners could translate to lower treatment costs.
