Flexi-dentures (e.g. Valplast) are a relatively new development in denture materials. The teeth are attached to a slightly flexible gum coloured denture base which extends to make the clasps, meaning they are completely metal free. Stability and retention come from the very close fit of the denture, and the flexible gum coloured clasps that extend from the denture to tightly grip the natural teeth.

Just as in acrylic dentures, flexi-dentures get their support from sitting on the ridges in the mouth.

They are the best option:

  • Where the mouth is unlikely to change
  • Great for a single missing tooth at the side or back (premolars/molars)
  • In patients where muscle control is compromised but not dexterity-for putting them in and taking them out, can be more difficult than acrylic dentures
  • Where there is an allergy to metal or a metal free denture is desired
  • As a thinner alternative to acrylic dentures when many teeth have been lost and hence more grip is required

Advantages of having a flexi-denture

  • Easy to adapt to
  • Comfortable to wear
  • Smaller and thinner than acrylic dentures
  • Better grip than acrylic dentures
  • Aesthetic - blend very naturally with the gums
  • Metal free
  • Good chewing experience
  • Slightly flexible so almost unbreakable
  • Don't require as much muscle control as acrylic

Disadvantages of having a flexi-denture

  • Plaque retentive and requires special cleaning product
  • Difficult to adjust and add teeth
  • Can be difficult to remove if dexterity impaired
  • Less chewing strength as denture flexes slightly in use
