Partial Dentures A missing tooth or missing teeth can be replaced
by a removable partial denture. There are two
types- depending on their framework. The plastic
partial denture and the metal partial denture.
Plastic Partial
Denture
A plastic partial denture consists of false
teeth, normally plastic, which are attached to a
plastic plate. In most instances these plates
are held in place by clasps which go around
remaining teeth. Sometimes when the plate is
temporary and replaces only one tooth (as in a
temporary plate during implant treatment) the
plate can be held in by utilising natural
undercuts round the teeth. Advantages
- Relatively inexpensive.
- Can be a good short term replacement for a
lost tooth.
- Easy to repair or make additions to.
- Gum coloured plastic can be used to fill out an
area where there has been
gum shrinkage.
- Can be made from biocompatible materials such as
dental "D”.
Disadvantages
- Removable.
- Bulky.
- Can cause damage to remaining teeth and gums.
What is involved?
Impressions are made of the upper and lower
teeth, then the bite, shape and shade of the
missing teeth are recorded. They are then sent
to the dental technician who makes the denture.
Depending on the type of partial denture the
turn around can be as little as a day - or as much as a week. Once the partial denture
is back we fit it into the mouth and make any
adjustments required. Occasionally sore areas or
ulcers can arise under a partial plate. Should
this occur please contact us so that further
adjustments can be made.
Metal partial denture
A metal partial denture can be made
to fit more accurately than a plastic one. The
false teeth and pink plastic representing the
gum is attached to a thin strong metal frame
normally made from a chrome cobalt alloy. The
framework can also be made of titanium or be
gold plated.
Advantages
- Better fit and longer life span than a plastic
partial denture.
- Again, gum coloured plastic can be used to fill
out areas where there has
been gum shrinkage.
- False tooth can easily be repaired.

Disadvantages
-
Removable.
-
Some bulk in mouth.
-
More costly than a plastic partial denture.
-
Less chance of damage to teeth and gums than a
plastic partial- but still
carries a risk of increasing the deterioration
of remaining teeth if a patient does not
practice good oral hygiene.
-
Not easy to make additions to though often still
possible.
What is involved?
As the life span of the metal partial denture is
dependent on the life span of the teeth on which
the claps will rest, we ensure that there is no
decay or gum disease before we start. Ideally
teeth which are heavily filled should be
crowned, and restorations which are as permanent
as possible- such as Cerec restorations, placed.
Some minor tooth adjustments are normally
required to optimize clasping the teeth.
Impressions are then recorded. Once the metal
framework has been made we try this in to check
the fit. Then the plastic teeth are added to the
metal framework set in wax. We check the teeth
for colour, shape and check that the bite is
correct. The plate is then sent back to the lab
and is processed. The completed denture is
fitted into the mouth and any adjustments
required are made. As with the plastic partial,
sore areas or ulcers can occasionally arise.
Should this occur please contact us so that
further adjustments can be made. |
