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

Dental Health and Caring for Seniors
Seniors are the fastest-growing age group in the U.S., in part because medical advances and preventive care are extending life and the quality of it. As the baby boomer generation ages, the senior population is swelling, along with their interest in maintaining healthy bodies and lifestyles. Good dental health is important to overall health and seniors must stay on top of their dental care. It is now possible to keep natural teeth and good dental hygiene plays a vital role.
Dental Decay and Gum Disease
Talk to your dentist about the proper care of your teeth and dental health. Brushing twice a day and flossing regularly are the most important steps you can take to keep your teeth and gums healthy. If age is causing your gums to recede, clean your teeth thoroughly, but be careful not to irritate or tear the gums. A receding gum line may also expose sensitive portions of teeth; careful brushing is important, as are toothpastes that offer sensitivity protection. If you have difficulty using a toothbrush or floss because arthritis or a stroke has impaired your agility, ask your dentist to recommend commercial products that will make the tasks easier. Bleeding or sensitive gums, constant bad breath, receding gums, and loose teeth are all symptoms of gum disease, which can hasten tooth loss. If you spot these symptoms, talk with your dentist about them before they cause pain and deterioration.
Watch Your Mouth!
After a lifetime of chewing and biting, many seniors have dentures, bridges, crowns, and, of course, their fair share of fillings. Over time, even the best dental hardware can wear out. If you feel changes in your mouth, particularly when you are eating, brushing, or flossing, bring them to your dentist's attention. You may take medications or have a medical condition that results in dry mouth. Saliva production is important to good dental health: it keeps the mouth moist, washes away food particles, and protects against decay from plaque. Enlist the help of your dentist, and ask about artificial saliva products.
Maintaining Your Investment In Dentistry
Don't stop caring for your teeth and mouth at this stage of the game! Keeping your teeth healthy means greater comfort and enjoyment as you eat, laugh, and speak. Good preventive care will give you something to really smile about and help to maintain your dental health!
