Learn About Conventional Over-Denture

A conventional over-denture rests over some healthy natural tooth roots. This approach was first reported in 1861. To understand this method, it is necessary to review some facts.

An Overview of Alveolar Ridge Dynamics

• Maintaining a denture on the jawbone ridge (called alveolar ridge) is essential to prevent it from becoming loose during eating, speaking, and other activities.
• Preserving the alveolar ridge facilitates denture stability.
• The body tends to conserve energy and nutrients by maintaining only structures with apparent immediate value. A typical example is the bulk reduction of a broken leg held immobile by a full-leg cast for a month or more.
• The body recognizes that the only one purpose for alveolar bone is to hold tooth roots.
• Alveolar bone no longer supporting a tooth root is removed, or literally dissolved away, by the body. This is called resorption, or simply shrinkage.
• Resorption progresses at varying rates in the same person at different times, and at different rates between different people. Resorption progresses rapidly within the first year of losing a tooth, after which time, the rate progresses at a slower pace.

From this overview, if the maximum amount of alveolar ridge is to be maintained, then preserving the maximum number of periodontally healthy tooth roots should achieve that end.

Preserving the Sensation of Having Teeth

Studies demonstrate that even though only roots are preserved, and a denture covers them, a patient still has sensory input sensations similar to that experienced with teeth, as opposed to individuals with conventional dentures and no preserved roots. Over-denture patients also appear to have a more natural perceived directional sense in their chewing activities. In other words, many patients relate that they still feel like they have teeth -- a positive comment.

Underlying Philosophy of the Conventional Over-Denture

If a patient's treatment plan to have a denture, and the roots of some remaining teeth are supported in healthy alveolar bone, then a conventional over-denture is a viable consideration.

However, only a licensed dentist can determine if a conventional over-denture is a suitable consideration for a certain person, after a comprehensive examination.

Some Characteristics of a Conventional Over-Denture

• Most of a tooth crown (that part of the tooth above the gums) is removed. This often necessitates root canal therapy if not already done.
• The remaining tooth, projecting above the gum, is rounded and usually covered with a similarly shaped artificial crown-like covering.
• Various configurations and extensions may be built onto some retained roots. In those cases, that portion of the denture overlying these configurations is modified to contain attachments that clip onto a framework or receive the individual extensions. In addition to preserving alveolar bone and sensory input, the denture is held securely in place, but may be comfortably and easily removed for cleaning.

Advantages of a Conventional Over-Denture

• Feels more like having teeth
• More retentive in many cases
• Helps reduce shrinkage of surrounding bone
• Reduces pressure to portions of the alveolar ridge
• Positive psychological advantage of still having teeth

Disadvantages of a Conventional Over-Denture

• Scrupulous oral hygiene is essential in order to prevent decay and gum disease
• The over-denture may feel bulkier than a conventional denture
• Frequent maintenance examinations are necessary
• Generally, this is a more expensive approach than a conventional denture

Ouch: Denture Stomatitis

Lots of false teeth wearers know about it: stomatitis.

Stomatitis - "denture sore mouth" - is the most common symptom of yeast invasion, where tiny blisters develop on the gums. Other signs are patchy white spots in the mouth, a burning sensation, or a persistent unpleasant salty taste.

It's not all your fault. Your denture has something to do with it.

Prosthodontics with soft liners or those relined with a non-pressure process can harbor troublesome yeasts. On the other hand, pressure-processed dentures (the bubbles are pressed out under heat) are less porous and therefore less friendly to Candida infection.

Two brand-name processes that resist Candida are Ivoclar acrylic and Astron vinyl. If you have recurring denture stomatitis, ask your prosthodontist about one of these processes at your next reline.

Beat the yeast

If you're not due for new false teeth or a reline, you can take measures to control the growth of Candida at home. Cleaning dentures using the following recipe will help: Soak your dentures for two hours, four times a week in equal parts bleach, dish detergent and water. Follow this by a one-hour soak in half vinegar/half water.

This brew seems to work, but some false teeth materials can lose color - and any denture with metal parts other than gold will suffer.

Even better...The Journal of the American Dental Association recommends using a denture care solution containing benzoic acid that looks effective in killing yeasts with no damage to the prosthodontics. Commercially it's called Oral Safe (Great Lakes Ortho Laboratories, Tonawanda, NY), available through your dentist. There are remedies to "denture sore mouth." Because denture problems are a pain you just don't have to live with.
