Avoiding Conventional Partial Dentures and False Teeth

Precision and semi-precision partial dentures, like conventional partial dentures, replace missing natural teeth with artificial teeth. However, the means by which they are retained in the mouth is different than a conventional clasp prosthesis.

To better understand these partial dentures types, it is best to first review the basics of conventional partial denture clasps.

How Conventional Partial Denture Clasps Function

Most partial dentures are usually kept in place by clasps. These are thin finger-like projections of special resilient metal alloy, or, in certain cases, plastic or plastic-like materials.

• Clasps rest on and around certain remaining natural teeth so that their ends extend into narrow areas below a gentler bulge on the tooth. Sometimes it is necessary to shape a tooth or make a crown for a tooth or teeth in order to develop the right amount and relationship of undercut and bulge for retention.
• When a partial denture is placed in the mouth, clasps gently spring over a tooth bulge and rest in a relaxed state within an undercut.
• A partial dentures are held in place during normal eating, speaking and other activities because clasps resist springing back over tooth bulges.
• Clasp resistance to removal is not great enough to prevent a person from comfortably removing their partial denture whenever they choose.

The Problem With Conventional Denture Clasps

Despite numerous successful conventional clasp designs, they do have some drawbacks.

• Clasps may at times become visible. Often, this is unavoidable and usually is not objectionable. However, for some individuals, the show of clasps is simply not acceptable because of personal circumstances and compromised appearance.
• Certain partial false teeth may function better with retentive means other than conventional clasps.
• Remaining natural tooth structures may be inadequate to accommodat conventional clasps. Therefore, dental crown or crowns may need to be fabricated to correct these deficiencies.

Semi-Precision and Precision Partial Dentures -- Viable Alternatives

Alternatives to conventional clasp partial dentures fall into two categories, both of which have no clasps to show.

• Semi-precision partial dentures are retained in the mouth by means of mechanical interlocking components. A specially-shaped extension of the partial denture fits into or onto a complementary receiving area or projection of a natural tooth that has been crowned.
  The components fit snugly and consist of a semi-rigid metal-to-other-surface interface, which may also be metal or some other resilient material such as nylon.
• Precision partial dentures are similar to the semi-precision type except that the mechanical interlocking components are manufactured to extremely high tolerances and are held together by precise alignment and a rigid metal-to-metal frictional interface of components.

Advantages of Semi-Precision and Precision Partial Dentures

• A cosmetically-enhanced partial denture as compared to conventional partial dentures
• No show of metal clasps
• Blends in with the conformity of remaining natural teeth
• Functions with a more even pressure on remaining natural teeth than conventional partial dentures

Disadvantages of Semi-Precision and Precision Partial Dentures

• Semi-precision partial dentures are the most costly to fabricate
• Usually some natural teeth need to be crowned
• More difficult to fabricate and adjust
• Some components may need periodic replacement

What To Do With The Broken Denture - Denture Repair

Even though dentures are fabricated from extremely durable materials, they will break, wear out, a tooth will come out, or their fit will change. Then its time for denture repair.

Accidents happen, dogs still like to chew on plates of the dental kind, and trash compacters have never taken kindly to dentures. In fact, it is frequently not a matter of "if," but rather a matter of "when" a denture will become broken, lost, or damaged beyond repair.

One can be assured that a problem will happen when least expected, and immediate, usually important, plans definitely will be altered unless a person is prepared.

Damaged Denture - How to Expect the Unexpected and Be Prepared

A short-term use duplicate denture will bridge the gap while a regular denture is being repaired, renovated, or replaced. Sometimes this type of denture is referred to as an "embarrassment denture" because it helps a person avoid the embarrassment of being without teeth in an emergency or during planned denture maintenance.

While this type of denture may be made at any time from an existing functional denture, it generally is fabricated immediately after a new denture is made. The embarrassment denture is neither as accurate nor as esthetic and durable as the original, but it is adequate and only meant for short-term use. The cost is generally considerably less than the original denture.

Such an interim prosthesis may be relined annually and adjusted in advance to fit the current changing shape of an individual's jaws, and therefore be ready to use at a moment's notice.

However, some individuals choose to have their embarrassment denture relined and adjusted only when they need the short-term denture. Following this latter course means that they will have to wait to wear their interim denture until an appointment can be scheduled with a dentist to complete the reline and any adjustments. But a reline for an embarrassment denture can be done in the dentist's office during a single appointment so a patient may leave with it refitted in the mouth.

In either case, a person would not be without a prosthesis while their regular denture is being worked on.

The Embarrassment Denture Facilitates Planned Periodic Maintenance

All dentures need to be periodically relined to accommodate the constant change in shape of a person's jaws. There are also times when the plastic body of a denture needs to be changed due to deterioration, or the entire denture replaced because of wear or poor fit from changing mouth conditions that can no longer be remedied by relining.

While relines can be completed in one appointment office visit, more durable relines may require that a dentist keep a denture for several days. Replacing the plastic body of a denture (called a rebase) takes several days and making a replacement denture takes several weeks.

It becomes easy to see how an embarrassment denture would solve being without one's regular denture for a period of time, even for planned maintenance, while getting on with one's life.
