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

Find A Dentist To Help You With Denture Repair
A frequent cause of a broken, chipped, or cracked denture is the impact of dropping it on the bathroom tile or into a sink. Sometimes damage to dentures happens when they are left in a place where children or pets are able to get at them let a dentist help you with that denture repair.
Dentures should be handled and stored carefully once out of the mouth to avoid chipping, breaking or damaging the pink denture base or the denture teeth.
If your denture is broken or damaged, visit a dentist to make sure that the denture repair provides the best denture fit, function, appearance and oral health.
Do-it-yourself denture repair can cause more damage than good to your denture and result in your needing a new denture. Do-it-yourself denture repair also can be very destructive to the gum tissues and bone ridges and cause irritation and sores.
A dentist has the training and qualifications, as well as the right instruments, supplies, and tools best suited to properly perform a denture repair.
If your denture is broken, keep any broken pieces of the denture. To prevent distortion of the denture, store the pieces in room temperature water until your dental appointment. The dentist will examine you and the denture and determine how to best restore the denture to its original condition.
Some denture repair, such as replacing a denture tooth, can be accomplished quickly, often in-office on the same day. More complicated breaks, such as a fracture of an edge that rests on the soft tissue inside the lips or cheeks, may involve obtaining impressions of your mouth and having the denture sent to a dental laboratory for the denture repair.
The ability to properly repair a denture depends upon the extent of denture damage, the past home care of the denture, the age of the denture and the fit of the denture at the time it was broken.
To maintain the best possible oral health and to avoid causing more damage to your denture, see a dentist for evaluation and denture repair. Often, home denture repairs require more extensive and costly reconstruction later.
