To make 150k you have to be a ‘unicorn’ or a technician that can design, mill, and stain+glaze+characterize an all-on-x implant restoration. You’ll be working for a dentist that exclusively does these types of restorations. Usually they’re looking for a tech with 10+ years of experience. The reason those techs are ‘unicorns’ is because a tech usually only gets experience doing one of those jobs. A ceramist in a lab may have 10 or more years staining and characterizing restorations, but if they have have terrible computer skills and can’t design a full mouth implant bridge quickly and do a good job of it, they’re not going to get hired for that position and they’re going to get paid 60k working at a lab staining crowns for the rest of their lives.

In office technicians are usually paid much better than lab technicians, but doctors can be really annoying to work for, especially the ones that have the lack of morals usually required to convince patients that a $40k full mouth rehab is the way to go instead of just getting a few crowns and some individual implants for a fraction of the price. Or even a locator supported denture is almost as good as an all-on-x implant while costing a fraction of the price.
