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 Problems
Are you a denture wearer who's afraid to be seen in public because your dentures are unattractive? Do you find yourself eating alone because you can't eat foods your friends eat? Do you carry your false teeth in your pocket? Denture wearers, without knowing it, can become dental "shut-ins." They begin, subtly, to reorient their lifestyles around ill-fitting or loose dentures. When dentures don't look or function properly, some people withdraw from their social lives and suffer depression and diminished self-esteem. Some even become recluses.
Tale of a shut-in
One denturist had a patient, a truck driver, who couldn't eat properly with his cheap dentures. At truck stops, he would take his food back to his truck and eat alone. He gave up his only social activity on the road, swapping stories with other drivers over a meal. For two years, he was a prisoner in his own truck. Many people can reverse a situation like this though. When prosthodontics look and feel right, denture problems become a thing of the past and the wearer's whole mental outlook can brighten. Eating gives pleasure and a feeling of security learned from early feeding experiences. It's an important part of most social occasions. When a person controls the quality and quantity of his food, he's able to achieve this sense of security and a feeling of self-esteem.
So, let's start fresh with some denture tips.
There's no need to feel unattractive or live in fear of a false teeth faux pas in the company of friends and family. A prosthodontist can help you regain
function, comfort, and a natural appearance by denture care and repair, or by just replacing or refitting them. Or, it might just mean using better dentures adhesive. Well-fitting prosthodontics are a small sort of miracle, but one that works wonders for your self-esteem. Don't be a shut-in. Call your dentist, and start smiling again.
