Dentist Service in Arizona. We do same day dentures and mini implant retained dentures. This is not exactly the same procedure as the all on four technique but offers a similar solution of secure dentures. The all on four can range from 40k-60k dollars. The mini implants system ranges from 6k-10k dollars a more reasonable affordable option that is more accessible for the general population. A free consultation could better explain the difference between the two and determine if you are a good candidate for the procedures.
