Acrylic Partial Denture,Densply Base Polymers
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
- 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?
- 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.
- 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
- Cheapest option needed
- As a temporary solution before more extensive and expensive
- Where trouble putting dentures in and taking them out is
