      The Mini Dental Implant Advantage

      Immediate Results

      Because they are less invasive, and don’t require the lengthy healing time of traditional implants, they can typically be loaded with crowns, bridges and dentures immediately.

      Less Healing Time & Fewer Visits

      Because mini implants are much smaller, placing them is a less invasive procedure—requiring less healing time and discomfort, and fewer visits.

      No More Decay

      Mini implants are made out of titanium—the same type of material that is used on artificial joints, and they are not subject to decay or periodontal disease.
