Why Have Regular Comprehensive Denture Check-Ups?

Regular and comprehensive examinations by a dentist are critical to ensure not only the proper function of a denture, but also the maintenance of total oral health.

Two significant things happen to a denture over time:

• It loosens -- Jaw ridges (alveolar ridges) will shrink in size and become smaller due to gradual and continuing bone loss (bone resorption) that occurs in everyone to varying degrees. This results in dentures becoming increasingly loose because they were fabricated originally to fit larger alveolar ridges.
• It wears -- Denture teeth will wear from use. In addition, uneven and irregular tooth wear develops as a denture becomes loose and starts shifting.

Denture loosening combined with uneven tooth wear results in a reciprocal and cyclical reinforcing synergism between the two destructive processes.

As a denture increasingly shifts on its soft tissue and jawbone foundation, it rubs and chafes the alveolar ridge. This causes irritation, soreness, and various types of pathology, including accelerated bone loss. In turn, this will cause more uneven tooth wear, which will cause more accelerated bone loss, and so on, back and forth. This is a gradual and unrelenting process that worsens over time, frequently at the expense of excessive jawbone loss, the thinning of overlying gum tissue, and the need to prematurely replace a denture -- unless detected and corrected in a timely manner.

If these problems are detected early, as during a regular check-up, they often may be remediated by adding plastic (acrylic resin) to the inside of a denture in order to allow it to fit closely against the alveolar ridge again (called relining or rebasing). In addition, irregularly worn teeth may be adjusted, or sometimes replaced or built up. Eventually, a denture will need to be replaced, but generally this will not need to be done too soon if a person visits their licensed dentist for periodic examinations.

Some Other Check-Up Considerations

• The need to adjust a denture, as determined by regular check-ups, helps keep a proper relationship between the jaws and thus maintains esthetics. Keeping jaws in a proper functional relationship, and sometimes building out certain denture surfaces, will support the face and help prevent a premature aging appearance.
• The temporomandibular joints or TMJs (the jaw joints located in front of each ear) undergo constant change in shape throughout life by a process called bone remodeling. This process is a functional response. If improper jaw function occurs, as a result of unadjusted dentures and improper bite, it is possible for the TMJs to remodel into a pathologic relationship. This could result in numerous pathological conditions, including impaired jaw function, headache, and other head and neck pains.
• Sometimes, more importantly than finding denture problems, is the opportunity to detect serious oral pathology, such as cancer, that may be discovered in early stages rather than later when radical and sometimes devastating therapy is necessary. The maintenance of healthy oral tissues is essential for optimum comfort in long-term denture wearers.

Conventional Removable Partial Dentures

A partial denture is useful for a person missing some teeth, but who still has a number of natural teeth.

This device also is called a removable prosthesis, and is a means by which artificial replacement teeth are held in the mouth. The prosthesis commonly is kept in place by means of clasps. These are thin finger-like structures, usually made of a special resilient metal alloy or sometimes plastic, that rest upon and wrap around some remaining natural teeth. Clasps keep the prosthesis securely in place, but still allow a person to easily take it out for regular cleaning and proper brushing of remaining natural teeth.

Some Reasons for Having Partial Dentures Made

• Replace missing teeth
• Improve ability to chew more naturally
• Chew food with confidence
• Make it possible to eat certain favorite foods
• Maintain a healthier and socially acceptable mouth
• Aid in the preservation of remaining natural teeth
• Help prevent or treat problems of the TMJ (the jaw joint)
• Often improve speech
• Help develop a more pleasing and confident smile
• Support the face -- often with a more youthful appearance
• Enhance self esteem
• Replace missing teeth in an economical way
• Add an additional tooth to an existing partial denture if a natural tooth is lost
• In most cases, crowning teeth is not necessary to fit a partial denture
• Partial dentures are usually easy to repair if they are broken

Esthetics and the Conventional Partial Denture

Generally, clasp design is reasonably esthetic, and often it is possible for them not to be seen. However, depending upon partial denture design, which is based on mouth conditions, there may be some show of clasps. Often, this is not an appearance problem. However, if avoiding an unacceptable show of clasps would compromise optimal partial denture design, various special attachments sometimes may be employed to do away with conventional clasps. These attachments are more technically complex and often are referred to as precision or semi-precision attachments.

How Long Will a Partial Denture Last?

Accidents happen, and the mouth is constantly changing. Partial dentures may no longer fit properly, can break or bend, or simply wear out. In fact, there is nothing made for the mouth that is permanent. Fractured clasps and so forth often may be repaired.

On average, a partial denture may be expected to last about five years. Depending upon circumstances, certain removable prostheses can last a shorter or longer time.

How Often Should a Partial Denture Be Checked?

It is best to have a partial denture, as well as the rest of the mouth, checked at six-month intervals. If left uncorrected, small problems can develop into major ones, which could cause disease, loss of teeth, or necessitate premature prosthesis replacement.

Partial Dentures Need to Be Relined

The jaw ridge that a partial denture rests upon is constantly changing. It is normal and necessary to regularly modify how a partial denture contacts the ridge. This maintenance correction is called relining, and on average, needs to be performed annually for optimal function. However, this is dependent upon how an individual's mouth changes. A licensed dentist can best advise when a reline is needed, and when a reline will no longer adequately restore proper function.
