What is a removable dental bridge?

Removable bridges or removable partial dentures are appliances made to replace one or more missing teeth in an arch.

Removable bridges all use the same type of tooth material but are differentiated by the materials used to hold the teeth to the partial denture and the way the partial denture attaches to the two (or more) teeth left in the arch (upper or lower).

What choices of partial dentures do I have?

Permanent partial dentures, also know as cemented bridges, provide a low-maintenance option in replacing missing teeth.

Temporary Acrylic Removable Partial Denture

Known as the “Flipper” in dentistry, this is generally the least expensive alternative to replacing missing teeth. Some flippers have a wire clasp to help attach the acrylic base to the teeth while others have no clasps at all. These removable partial dentures have an acrylic base made exactly the same as a complete denture. The biggest benefit of this type of removable partial denture is that it can be made before any teeth are removed and delivered the same day as the extractions are done. Then, if more teeth need to be removed later, teeth can be added easily and economically to the flipper.

Flippers have a number of disadvantages:

  • They tend to be somewhat irregular in shape and the acrylic is brittle. These partial dentures tend to break frequently, especially in the lower arch or when functioning against a single upper central replacement tooth.
  • For strength the acrylic tends to be thicker than other types of partials and may be more difficult to become accustomed to.
  • They tend not to be as retentive or stable as removable partials that are retained by clasps around the teeth.
  • Since they rest on the tissue, they tend to sink below the level of the teeth over time and need to be replaced, thus the term “temporary.”

Cast Framework Partial Dentures

As the name implies, these are partial dentures which have a cast metal framework supporting denture acrylic and teeth. These partials are mainly tooth supported and retained and are therefore extremely stable. The metal framework is cast extremely thin and is therefore much less noticeable than the acrylic framework partials. The clasps are designed to retain the partial in place and the teeth are altered slightly to allow the patient to bring teeth all the way together without interfering with the clasps. This also makes it possible to place the clasps in positions which are less visible than wire clasps. The cast framework is also very strong and is less likely to break than acrylic, and since the metal does not rest on tissue, but on teeth, these partials do not sink below the level of the teeth. Finally, since there is little contact with the soft tissue, sore spots are not much of a problem.

Partial dentures? Can't get used to them.

I got partials (both sides, upper and lower) four weeks ago. No pain, but I can't adjust to the huge amount plastic behind the top and bottom front teeth. I am conscious of this big wad of plastic in my mouth every minute. My tongue cannot find a place to rest. It's still hard to speak clearly. (After twelve years of teaching foreigners how to pronounce English, I know how to pronounce, and am embarrassed when people ask me to repeat myself.) Is this normal?

Another update re teeth

RECAP: Went to periodontist and he said cost would be about $10,000.
Letter sent to my dentist: "we discussed a practical approach to hopefully save enough teeth to act as anchors for a least transitional partial dentures. I have deemed teeth #6,7,8,9,10,13,14,18,19,23,24,2,26 and 30 hopeless mostly due to periodontal reasons but also obvious significant restorative needs. You will be extracting these teeth. I have told Susan...there are still some teeth that are fairly solid and, if treated periodontally, can be saved. However, saving some of the teeth may depend on the major restorative needs

Veneers versus dentures

If you have teeth that can be saved, then hold on to them and get veneers. For the teeth you are missing you can get partial dentures (cheaper) OR get permanent implants (more expensive).
If you don't have insurance this will be expensive no matter what. Get your yellow pages out, find dentists, and start calling (explain your situation and what you think you need). Many dentist (the legitimate kind) will actually give you a free consultation and their ideas on what can be done.
For a cleaning and some ideas as to where to go, try UCSF - I believe they take people like you for clinical care and assessment

Denture and tooth cleaner. Use baby shampoo!

I had an infection in my mouth and was told to wash my dentures in baby shampoo to clean then so the chemicals from Polident etc. didn't irritate the sore. The baby shampoo gor off old plaque that Polident etc. wern't touching and on the partial, the stainless comes bright and shiney as well. I then tried babyshampoo on the plaque on my real teeth and it disolved the plaque under the gum line in three tries and now my teeth don't bleed. It has been three months and no bad side effects.
