Atlantis' custom base is our largest selling abutment by far. I average about 50-60 a month. We don't bill separately for the abutment. For all our screw retained cases, we charge a flat fee that includes the abutment, the soft tissue model, the shipping, the crown, and the cementation labor fee. We charge the same whether it is an Atlantis Custom Base or a Straumann Variobase. The Atlantis option is better because the core file generated from the abutment design is outstanding and makes the work flow seamless. The amount you charge is largely dependent on what the market in your area will bear. We charge more than most labs in our area, but we also offer a higher quality restoration than the larger labs. We fill a different niche than the "glidewell" style labs.
Sturlat, one of the best purchases we have made in the last couple of years is a titanium annodizer. It takes about 30 seconds to turn a silver titanium abutment gold. An annodizer costs about $300 and you can easily get that back on the extra charge for that service to your doctors.
