When making partial dentures, we work from two impressions. The first provides an overview of the size of the mouth and muscles attached to it. Based on this model, called the ‘primary’ model, we make a custom impression tray. This tray will be better fitted to the size of the mouth and provide a more precise impression result to determine the length, thickness and contour size of the future denture.
We then take a measurement of the joint. We determine the length of the upper and lower teeth as well as the relationship between the two. The artificial teeth must be level with the height of the natural teeth. In some cases where certain natural teeth are worn out, it is possible to compensate with the partial denture to ensure better function. The teeth must fit together and slide against each other easily to allow optimal chewing. Based on these measurements, teeth will be carefully set one by one, taking into account the patient’s anatomy and preferences.
A fitting is required to complete the job. This allows the denturist to check her work, but at the same time, this visit allows the patient a glimpse of the result. During this visit, it is easy to make changes to the positioning of the teeth. With the patient’s approval, the dentures will then be completed permanently.
That being said, the work is not finished when the dentures are completed. The patient has to undergo an adjustment period. During chewing, certain areas of the mouth can become sensitive, even painful. The dentures must be meticulously adjusted at the sensitive areas. Other discomforts can also arise, and the patient must notify the denturist, who can examine and adjust the dentures so that everything works properly.
