New Dentures: What to Expect from Complete Dentures

Complete dentures are less than perfect replacements for natural teeth. However, they have proven to be effective for countless individuals and can be comfortable to wear if a person has reasonable expectations and recognizes that there definitely will be an adaptation period.

It is important to understand that "showing off" with new complete dentures often ends in an unpleasant and embarrassing experience. One must first practice with their new prosthesis and learn what limitations and compensations need to be considered.

The old adage of "learn to walk before you run" certainly applies to the successful, secure and comfortable wearing of complete dentures.

Some Factors to Consider When Wearing New Complete Dentures

This is not an exhaustive review of new complete dentures learning considerations. However, these are common areas of concern. If a person has a unique question or problem, they should always contact their dentist or prosthodontist for advice and direction.

Full feeling:

When new complete dentures are first placed in the mouth, they frequently feel fuller, and it may not seem like there is enough room for the tongue. When a person has been without teeth for a period of time, the inside of the cheeks and tongue can become slightly thicker or feel fuller. When new complete dentures are first inserted, this slight fullness may feel enormous. It actually is not, and the full feeling will usually go away very shortly if an individual does not dwell on the sensation.

Previously unsupported sunken facial structures and muscles usually will be supported with new complete dentures to a normal position. These facial tissues adapt rapidly to their regained normal positioning and will feel less strained and more flexible. A more youthful appearance results in many cases.

Phonetic difficulty:

When a person is used to producing speech sounds without teeth or with old complete dentures that no longer preserves proper jaw relationships, they generally have adapted their speech in such a way as to accommodate these abnormal conditions. However, when correct jaw relationships and contours are established again with new complete dentures, there may be some difficulty producing certain speech sounds clearly, and teeth might even click together in some instances. This is temporary.

If an individual makes an effort to speak slowly and clearly, pronouncing words very precisely, the tongue and other muscles will adapt quickly to produce clear speech. It is often useful to read a book or newspaper out loud, carefully pronouncing each word precisely.

Sore spots and irritations:

These may develop as new complete dentures settle in. This may require some adjustment to the body of the complete dentures, and, more often, careful adjustment of the bite resolves these types of problems.

At times, the jaws may feel tired and soreness can develop. Taking complete dentures out to rest the mouth for a time frequently helps resolve these problems.

Chewing patterns:

Chewing patterns will need to be developed over several weeks, starting by chewing with small pieces of soft food and gradually increasing the firmness over several weeks. Generally, food should be chewed on both sides of the mouth at the same time.

Front teeth are considered primarily for esthetics and speech and to a lesser degree for function. Food is not bitten off with the front teeth efficiently; rather, the bolus of food should be held by the complete dentures, near the corners of the mouth, and torn off by rotating the hand holding food in a downward motion. This will increase chewing efficiency and reduce irregular denture rocking.

A complete dentures patient needs to take control and keep a positive attitude for optimal results.

Metal Based Denture vs Plastic - Which is Best for You?

A metal-based denture is one in which a portion of the denture body is made of a substantial metal casting rather than all plastic (acrylic resin). This procedure is usually done on the lower denture.

There are two types of metal-based dentures.

Standard metal-based denture

The metal base portion of the denture is in direct contact with underlying supporting tissues.

The base is fabricated from a special medical grade alloy that is hypoallergenic and very biocompatible with tissues. Generally, tissues in contact with this type of material are very healthy in appearance.

Modified metal-based denture

The metal base portion of the denture is not in direct contact with underlying supporting tissues. A soft or hard plastic liner may be interposed between the metal and supporting tissues.

A soft liner is generally preferred to hard plastic since it is more comfortable to wear; however, the soft liner usually should be replaced on an annual basis.

The Rationale for a Metal-Based Denture

Facilitates the avoidance of disruptive forces

Sometimes it is necessary to construct a very narrow denture in order to avoid any structures that would loosen the prosthesis, such as muscles flexing, and so forth. In addition, necessary surgical procedures to reposition a muscle attachment (called a frenum) can sometimes be avoided with these narrow type dentures.

However, such narrow dentures are weak and tend to break quite easily when fabricated just from plastic. A metal base provides the needed strength to design a very narrow denture in order to follow the confines of a patient's lower resorbed alveolar ridge (the remaining bony ridge). In addition, the metal base provides long-term dimensional stability and strength that is not enjoyed with an all-plastic denture base.

Provides a more natural feeling

The added weight of the metal base provides a more natural perception for many patients. Many patients prefer the additional weight on the lower jaw.

A private study measured the actual weight of cadaver jaw ridges and teeth that would normally be lost after the extraction of teeth and associated natural shrinkage of the jawbones. It was found that the weight of these tissues closely approximated the weight of a metal base. Therefore, it is likely that the more natural feeling perceived by persons wearing metal-based dentures is probably real rather than imagined.

The additional weight of a metal base also contributes to lower denture stability by causing the denture to settle down onto a jaw ridge.

Advantages of Metal-Based Dentures

• Very biocompatible and hypoallergenic with healthy-appearing supporting tissues
• May include a soft liner
• Can be relined easily
• Provides added strength for easily broken narrow dentures
• Facilitates fabrication of stable narrow-based dentures that are designed to avoid contact with disrupting muscle forces
• Sometimes facilitates the avoidance of surgical procedures to reposition frenum
• Patients perceive a more natural feeling from the added weight
• Weight may contribute to additional denture stability
• Dimensionally very stable when compared to all-plastic-based dentures during fabrication and over time

Disadvantages of Metal-Based Dentures

• Generally difficult to reline standard metal-based dentures; modified metal-based dentures (described earlier above) are easier to reline
• More costly to fabricate
