Why the same procedure gets very different quotes
Two clinics can both quote "All-on-4" at very different prices, and the gap often comes down to what's actually included rather than one being a better deal — it's worth reading past the headline number.
Implant brand and quality
Established, clinically proven implant brands typically cost more than lesser-known alternatives, and this is one of the biggest drivers of price difference between clinics. This is directly tied to long-term reliability, so it's worth asking specifically which brand is used rather than assuming "implant" means the same thing everywhere.
What's bundled into the quoted price
Ask specifically whether the quote includes the initial consultation, the 3D scan, the temporary bridge fitted after surgery, and the final permanent bridge — some quotes only cover part of this, with the rest billed separately once you're already committed.
Whether a bone graft or sinus lift is likely, and whether it's included
If your case may need additional bone work, a quote given before reviewing your scan can't account for that — get a price based on your actual 3D imaging, not a generic package rate.
Follow-up and warranty terms
Check whether aftercare check-ins and the warranty period are included in the price or treated as extras, since this affects the real cost of the treatment over its lifetime, not just on the day of surgery.
The one question that cuts through most of this
Ask directly: "what would make this final price change?" A clinic that has genuinely reviewed your case should be able to give you a firm answer, rather than a range that depends on factors they haven't actually assessed yet.
