You can’t change public perception and clear aligners are mainstream. I’ve never seen an ad for head gear and retainers. You still have to sell the patient and metal wires are a tough sell. I’m not talking about major movements, there is still a place for springs and major leverage that Invisalign can’t achieve. Inman aligners are probably more effective and brilliantly engineered but less patient acceptance and much higher cost perhaps. I know very little of the market.. I was speaking more of Hawleys and simple appliances.
