Immediate Replacement Teeth Immediate replacement teeth (dentures) are fitted after the extraction of any remaining teeth. It is usual to see the patient within a day or two following the extraction of the teeth and the fitting of the replacement teeth to make sure that they are reasonably comfortable and that healing is progressing normally. Appearance Immediate Replacement teeth (dentures) will copy the natural appearance of your teeth before they were removed. Family and friends should be unaware of any change other than that you may seem to smile more readily and are able to eat more comfortably. Even small changes in colour or tooth position can be noticed and, although these are sometimes desirable, it is much better to incorporate them in a later set of dentures after the jaws have healed and everything has settled down. Comfort & Fit The fit of Immediate Replacement teeth (denture) is always a compromise, as when the teeth are removed the body remodels the bone of the jaw. The more teeth to be removed, the more remodelling there will be. The fit of the denture is compromised by these rapid changes. We can compensate by the use of tissue conditioner and similar substances. However, the first three months following extraction and fit of an Immediate Replacement Denture is a difficult period. Healing Changes in the Jaw Even with the best of planning and the benefit of much experience, we cannot entirely predict the amount of bone that will be remodelled following the extraction of the teeth. Changes in the body are individual, the most rapid changes occur over the initial three months. Tissue Conditioner, Re-lines and Re-base Tissue conditioner is a self-curing plastic that remains soft and flexible. It will adapt to the shape of your jaw and greatly increases confidence in the denture. The tissue conditioner loses plasticiser’over time (2-3 weeks) and becomes hard. Also it takes up water and therefore ‘ bacteria. It is recommended that it be renewed frequently. A self-curing plastic (acrylic) that is similar to the denture base is used for more permanent alterations to the fit. It is also recommended that the entire fit of the denture be re-made nine months to one year following the extraction of the teeth. Re-lining is often undertaken on the same day, whereas the re-making of the fit surface of the denture using a heat cured resin (re-base) requires two to three days of work in the laboratory. Balancing the Working Action of the Teeth At the time of fitting the replacement teeth (denture), it is often suggested that the dentures be ‘balanced’together, known as a Re-Mount, so that there is even contact at the correct height or interval between the upper and lower jaws when the mouth closes.
