Missing teeth is a common problem for many people who have had
teeth removed because of extensive cavities, gum disease, injuries,
and those who may not have developed some of their teeth due
to an inherited trait. The three most common ways a dentist
can replace one or more missing teeth are a bridge (a series
of joined caps), an implant(s), or a removable partial denture.
Although a bridge or dental implant(s) has certain advantages
when compared to a removable partial denture, in some cases,
the removable partial denture may be the best or only choice
are three basic types of partial dentures. The first is a cast
removable partial denture, or “cast partial”, and consists of
a metal base that has acrylic teeth attached to it. Metal clasps
are the hook-like structures that help hold the removable partial
denture in place. Although the cast partial can be a bit cumbersome,
it has been used successfully for decades in the dental profession.
The second type of removable partial denture is the all-acrylic
variety, sometimes referred to as an interim (temporary) removable
partial denture or a “flipper”. The third type is the Valplast
partial denture, which is a nylon thermoplastic material that
has several advantages over the other two types of partial dentures.
partial dentures have no metal clasps and are very light weight.
The material is translucent, so the patient’s own gums show
through, giving a very natural appearance. Valplast partial
dentures can be used to replace many or few missing teeth, and
can even be modified to replace a missing tooth on only one
side of the mouth, greatly enhancing its comfort. Valplast can
be used for full dentures on people who have irregularities
in their jaw bone that would preclude the use of the standard
rigid acrylic material. Valplast is an option for cosmetic improvement
of teeth that appear elongated due to recession of the gums,
and for people who are allergic to the acrylic found in other
types of partial dentures. Another great advantage of Valplast
is its resistance to breakage, as it is surprisingly strong
relative its size and weight.
partial dentures are an excellent option for the replacement
of missing teeth. The cost of treatment is usually much less
than either a permanent bridge or dental implants and can be
completed in just two or three short visits. Durable, lightweight,
and esthetic, Valplast should be considered for anyone who needs
replacement of missing teeth.
They are not for people who smoke, smoking will stain them.
They are hard to repair if anything goes wrong or you need to
add a tooth. However many people love the feel of them.
How do you wear a removable partial
partial dentures are attached to your natural teeth with metal
clasps or devices called precision attachments.
long should you wear a partial denture?
you may want to wear your partial denture all the time. Your
dentist will give you specific instructions on how long it should
be worn and when it should be removed. Generally, your mouth
tissues need to rest so it is advisable that you take out your
partial denture at least 15 minutes per day.
the partial denture change the way you speak?
partial denture may help your speech. It can be difficult to
speak clearly when you are missing teeth.
a new denture has been inserted, it ought to retain in the mouth
quite nicely due to the fact that the shape of the inside of
the denture base conforms closely to the shape of the gums.
(Please note that good retention (suction) of the denture does
not necessarily mean that the same denture is stable.)
Unfortunately, the longer you wear the denture, the more your
gums change underneath it, and the looser it gets. In order
to restore the retentive qualities of the denture, and to prevent
the production of flabby gum tissue under it, you should have
the denture professionally relined at least every two years.
There are actually three types of denture relines: Hard, Soft
is the kind of reline that should be done on all full dentures
every two years. The dentist removes some of the plastic from
the inside of the denture, and then fills the denture with a
soft material (think of soft putty) which, when replaced in
the mouth, conforms to the contours of the tissues, and then
hardens to a rubbery consistency. When the denture is removed,
the denture now contains an accurate impression of the shape
of the gums. The denture is sent to the lab, and the impression
material is replaced with pink, hard acrylic in exactly the
same shape as the original impression material. When returned,
the denture now conforms to the contours of your mouth and should
make maximum contact with the tissues producing maximum suction.
In our office, the impression is scheduled for first thing in
the morning. The patient goes home without the denture, but
returns later the same day (usually early afternoon) for the
insert (fitting appointment).
a patient finds that he cannot wear the denture because his
gums are too tender, and he keeps getting sore spots. In cases
where the patient is unable to wear ordinary dentures because
of tender gums, the denture can be relined with a material that
remains somewhat pliable for a year or two before it needs replacement.
The consistency of this material can range from waxy to hard
rubber, and is generally less likely to give the patient sore
spots than ordinary pink acrylic.
by the time that a patient resorts to a soft reline material
to make the denture wearable, it usually means that factors
other than simple sore spots are partly to blame for the difficulties
that the patient is experiencing wearing the dentures. These
could include an overbuilt denture or a resorbed ridge which
is so unstable that the patient must keep constant force on
the teeth to keep them in place. Both of these conditions can
be corrected, sometimes with less expensive simple surgery or
sometimes with much more expensive implant retained dentures.
Temporary relines (Therapeutic
Frequently, by the time a patient with an old denture finally
shows up at the dentist's office looking for a new denture,
the dentures have not been serviced for such a long time that
the gums are in terrible condition. They may be red, swollen
and quite misshapen. Relining the old denture, or building a
new one using impressions taken while the gums are in such poor
condition would lead to a denture that would simply perpetuate
the problem with the new appliance.
faced with situations like this, a dentist will frequently resort
to a temporary, or palliative (medicated) reline material to
allow the inflammation to subside. This reline makes the denture
fit much more tightly, and is usually soft and pliable. It will
not last more than a few months, but the patient wears it for
a few weeks until the gums return to a more normal state. After
this happens, then the patient is ready for his new denture
or hard reline.
is not wise not wear your dentures all day long without giving
your gums at least two hours per day to recuperate. If you do,
it causes rapid loss of the underlying bony support and its
replacement with soft flabby tissue which causes your denture
to become unstable. Leaving them out overnight is the best plan.
also need to clean and deodorize your dentures at least once
a day to avoid serious denture breath (ask the grandkids). Leaving
your dentures out overnight and getting into a routine of denture
hygiene is the best plan. You can soak them in a commercial
denture cleaner, but you can really do a better job and keep
them fresher by following these directions:
the dentures thoroughly with a soft brush and plain dish detergent.
Never use toothpaste or an abrasive powder. Denture teeth are
made out of multiple layers of different coloured acrylic to
make them look more natural, and scrubbing them with abrasive
powders like Comet or Babbo or using hard abrasive brushes will
remove layers of the plastic making them look dead and eventually
turning them into flat blocks of plastic. Plain dish detergent
will work as well as any other cleaner.
them overnight in a dilute solution of laundry bleach. A tablespoon
of bleach in 6-8 ounces of water is more than strong enough
to remove stains, disinfect and thoroughly deodorize them. Just
rinse them off in the morning with copious water before inserting
them in your mouth. If you keep them in a covered container,
you only need to change the solution once a week. You will be
quite surprised at how much better they smell throughout the
