How did you compare clinics for Dental Implants?

I think Clinic B asking questions is not a bad sign. For dental implants, one place gave me a cheap fixed price in one message, but later they said bone scan could change everything. The clinic that asked for x-rays, medical history, and travel dates felt more careful. I still compared prices, but I wanted to know what was included if the plan changed.

From my side, slow questions were normal. I sent x-ray and they still said final plan only after scan in person. It frustrated me, but later I understood they were not trying to sell one fixed package to everyone.
