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

Denture Identification

False teeth, like all personal items, can be lost or misplaced. Denture replacement after losing a denture is never a pleasant experience. A person whose denture is lost or misplaced may have difficulty chewing, eating, and speaking, and may be embarrassed by their looks.

Often, a missing denture is linked to being hospitalized or entering a nursing home. Personal items such as dentures or eyeglasses can be misplaced because of an accident, sudden illness, or admission to a hospital. Also, it is not difficult for a nursing home resident or staff member to misplace a denture.

Nursing homes, similar to hospitals, are busy places. Residents often are recovering from serious illness, have recently been discharged from a hospital, are undergoing rehabilitation, or have cognitive and mental health problems such as Alzheimer's disease or dementia. If lost or misplaced prosthodontics are found and they are not labeled with something that identifies its owner, it is very unlikely that it will be returned.

• How a denture can be misplaced in a hospital or nursing home:
• Wrapped in a napkin and left on a food tray
• Placed in pocket of clothing
• Removed during a nap and left in bed sheets
• Other patients take denture
• Staff places denture with another patient's belongings

False teeth can be labeled with an identification label at any time. They can be labeled when they are initially constructed, or the label can be added at a later date. A dentist or prosthodontist inserts the labels in an area of the denture that does not interfere with its function or looks. A dentist or dental technician should be responsible for labeling your prosthodontics. Do not label them yourself with home items such as a felt tip pen or marker. Denture identification can be any combination of a first name, last name, initials, or the first initial of the last name with the last four numbers of your Social Security number.

Loss of false teeth causes inconveniences and problems for the sick, the old, the mentally impaired, and family caregivers. Replacing prosthodontics also requires getting used to the new fit and appearance. Denture replacement also involves cost, arranging for a dental visit, time, and transportation. To eliminate the inconveniences of a lost or misplaced denture, consider the benefits of denture identification.
