Interim prosthesis: Everything for the optimal intermediate solution

The interim replacement is a simple, removable plastic-based partial denture. It is often referred to as a transitional prosthesis. There are many situations where an interim prosthesis is needed. Find out here, when an interim prosthesis as a transitional denture makes sense.

What is an interim prosthesis?

The interim prosthesis is a simple removable partial denture. It serves as a temporary solution after tooth loss. The goal is to quickly close new tooth gaps. Thus bone resorption is counteracted at an early stage, since bones recede due to lack of load. The intended wearing time of the transitional prosthesis depends on the healing process of the wound after a surgical procedure. It is usually two to three months.

What materials is the replacement?

Transitional prostheses are made of polymethyl methacrylate (PMMA). PMMA is in well manufactured, dental plastic. An interim care can be made quickly and individually. It is optimal as a temporary solution before a final denture. The partial denture is made of plastic and holds by curved braces on the own teeth. The brackets are visible. These simple retaining elements are incorporated into the prosthesis. The provisional denture can only be used with a dentate residual dentition.

The edentulous jaw is almost always an Immediatprothese produced. This replaces all the teeth and is relined after the healing phase so that it fits well.

Little wearing comfort, short wearing time

The brackets are easy to bend. Therefore, the wearing comfort for the patient is limited. Many patients complain of a wobble of the prosthesis or over bruises. It is not possible to ensure a permanently optimal seats of the interim replacement, because the jawbone changes in the healing phase. But that is not the purpose of a transitional prosthesis.
The prosthesis should only be used during the healing of extraction wounds. Subsequently, a definitive fixed or removable dentures can be made.

In which cases is a removable interim prosthesis useful?

When existing teeth have to be pulled, wounds and gaps in the row of teeth are created. These gum and bone wounds need to heal before a final restoration can be made. At the same time, the aesthetics and chewing function should be restored. As an interim solution, a cost-effective, removable temporary can be made.

This temporary also counteracts excessive swelling after extraction. If the transitional prosthesis is inserted immediately after tooth removal, pressure from the prosthesis can not cause excessive swelling.

Is it possible to wear a provisional restoration permanently?

No, a permanent wear of the removable interim prosthesis harms your remaining teeth, the periodontium and the jawbone .

The aim of every dental prosthesis is to distribute chewing forces optimally to the entire chewing system: The chewing system consists of teeth, bones and the jaw joints. With an interim prosthesis, however, the chewing forces can not be meaningfully transferred to existing residual teeth. In addition, the bone changes during healing, so that the prosthesis quickly does not fit properly. Therefore, too long wearing will cause bad stress. The jaw recedes and existing teeth can become loose.

In which cases are interim prostheses used??

To restore chewing function, aesthetics and phonetics after implant placement or tooth extraction
To counteract excessive gingival swelling after tooth extraction
To provide residual teeth with an antagonist (counteracts outgrowth of the tooth)
To maintain the distance between upper and lower jaw
To maintain healthy tooth positions and prevent tooth tilting or tooth migration
To maintain normal face shape and prevent visible facial changes

How does the treatment proceed with an interim prosthesis??

When planning a new denture, a thorough examination of your teeth and jawbone is necessary. Frequently, teeth must first be pulled in front of a new denture. Then it makes sense to use an interim prosthesis so that you can continue to smile, talk and eat without any problems.

For a supply of interim prostheses, the following procedure is suitable:

Step 1: Taking an impression of your upper and lower jaw

Subsequently, models are produced from these impressions in the laboratory. Your dentist sends the lab the teeth to be removed and the desired clamp positions.

Step 2: Drawing sick teeth

The non-maintainable teeth are removed when the dentures are ready.

Step 3: Integration of the interim prosthesis

Immediately after removal of the teeth, the dentist can use the interim prosthesis for you.

Step 4: Control date

A few days after the extraction, a check-up takes place. Here, the wounds can be controlled and any pressure points removed.

Step 5: Planning your definitive dentures

Together with your treating dentist you now have enough time for further treatment planning. Whether implants, bridge or removable dentures, during wound healing you can think twice about which definitive restoration is right for you.
