Does it happen often that patients come in asking for Invisalign specifically? The orthodontist saying, no, we're using Spark or ClearCorrect, and the patient going, well, I'm not going to get it done here then?

I think it’s increasingly common that patients are asking for Invisalign by name, for reasons that I think are obvious. What the conversation maybe looks more like is, yes, we offer Invisalign. We also have some alternatives to Invisalign; we have some other clear aligner options that are less effective but are going to give you the same result. I think that's an easy conversation. I don't think that's a conversation that that most orthodontists or dentists could mess up. If they're an existing patient or a patient of record, then they would be highly likely and inclined to say, yes, that's fine. I just want clear aligners in the end. I think that, at a certain point, while the Invisalign brand has really peaked in terms of brand awareness, consumer awareness, at the same time, it could very quickly go away. When now we're just talking about clear aligner treatment in general, I don't care what brand it is; I just know that I want my teeth straight. As a consumer, as a patient, I just want my teeth straight. I don't want to wear wires and brackets. I just want clear aligners.
