Luckily .... the Corp I work for is not a big fan of aligner tx. I've never liked aligners since they were 1st brought to market. I just never felt I had any control of the treatment. I feel like Aligners were originally intended for those adult patients who had money and did not want traditional braces. They could afford the larger down payment necessary to cover the initial cost of the aligners. Enter your average patient looking for financing and lower cost treatment (i.e Corp patients) and the initial upfront cost of aligners is too much. Add additional aligners, scans (impressions) when the treatment isn't tracking properly and all of a sudden .... the ROI per appt becomes less and less. Yes .... additional aligners is no charge (comprehensive cases, maybe other cases??), but YOUR time is valuable.
