What are Acrylic Dentures?

Acrylic dentures consist of the denture teeth attached to an acrylic base plate.
How they Work?

Stability (not rocking) and retention (grip) come from 3 aspects of the acrylic denture:

  • The denture fitting closely and tightly against the gums and natural teeth
  • The use of wrought metal clasps (retainers) to grip the teeth
  • In cases where only a few teeth remain; a well fitting base plate, covering as much of the hard tissue, (that’s the jawbone, palate and ridges) in your mouth as possible.

They are ‘mucosal borne dentures’- meaning they get support (resist chewing forces) by sitting on your ridges.

What are their Advantages?

• Cheapest
• Quick and easy to make (though not necessarily to get right)
• Easy to change- add teeth, reline etc.
• Easiest to take in and out

What are their Dis-advantages?

• least comfortable and well tolerated
• least stable
• least grip (retention)
• often bigger and more bulky (unless a single front tooth)
• require more muscle control
• tend to break more easily
• need to cover the palate if teeth are missing on both sides – this affects telling temperature and the chewing experience.

Best Situations?

• Lots of changes are expected to be needed
• As a training denture for wearing a complete denture
• Trauma cases- where teeth have been knocked out
• Immediate dentures- where a tooth is to be removed as they are most easily relined
• Cheapest option needed
• As a temporary solution before more extensive and expensive treatment
• Where trouble putting dentures in and taking them out is experienced
