Implant supported dentures are screwed into implants and are only able to be removed by a dentist. A slight space exists between the gum and the denture to allow for cleaning, but its small size allows the denture to cover less of your gums.
Dental implants have a high clinical success rate of over 98% and patients who have opted for implant assisted dentures or bridges, often comment how similar eating and speaking with them feel to their own natural teeth.
