Chromium-based dentures offer a sophisticated but removable method of tooth replacement, that is particularly useful when multiple teeth have been lost. They are constructed by highly skilled technicians. The teeth are matched in shape and colour to the remaining dentition, these are set in pink acrylic ‘gums’ which are in turn supported by a chromium frame. These dentures are small and lightweight and can soon be forgotten by the wearer. Small metal components are sometimes visible but these impart the stability that can give the patient added confidence.
WHAT IS INVOLVED?
- Treatment options can be many and varied. We would recommend starting with a consultation to assess your case and discuss your particular requirements.
- Several appointments are required at approximately weekly intervals.
- Generally impressions are taken at each of the first two appointments. Initially, ‘primary’ impressions are required so that ‘special’ trays can be constructed that are unique to you. Then the ‘secondary’ impressions are taken in these trays. This method provides the accuracy required by the exacting casting technique utilised in the construction of the chromium frame. This work is performed by highly skilled dental technicians.
- A further appointment would commonly be required to ensure that the chrome frame fits perfectly and that the bite has been accurately recorded.
- Only then can the laboratory fit the teeth to the chromium frame. Initially, they are set in wax so that at the next appointment you will have the opportunity of seeing your new denture for the first time. At this appointment, your dentist will also be checking a number of other clinical considerations like the stability and the bite.
- When you are completely happy with your new look, the laboratory will complete the acrylic work on your denture, enabling you to take your new teeth home with you at your next visit. Your dentist will give you instruction on any special day-to-day care required when wearing false teeth.
- Like a new pair of shoes, dentures can cause a little discomfort at first. Your dentist will see you as often as necessary in order to speedily achieve the best result. Frequently perfection is achieved from day one, especially amongst patients familiar with wearing bulkier acrylic dentures.
THE ADVANTAGES OF CHROME DENTURES
- They usually cover much less of the mouth than their acrylic alternatives and the components are much thinner. The wearer should, therefore, experience greater comfort and less interference with eating and speech.
- They can offer a cost-effective solution especially in cases where there is multiple tooth loss.
- They do not require any teeth to be prepared excessively and thereby permanent changes to the remaining dentition are avoided.
- They tend to be supported by the teeth, thus minimising damage to the gums.
- They are more hygienic as the chrome does not harbour bacteria.
- They can be removed, thus making cleaning of the patient’s own teeth easier.
- They can allow the addition of extra teeth to the denture in the event of further natural teeth being lost.
THE DISADVANTAGES OF CHROME DENTURES
- They may not impart the confidence enjoyed by patients that have been provided with more permanent, fixed replacement teeth (for example, implants or bridges).
- They may not be appropriate if further tooth losses are anticipated, (for example, if the patient is suffering from uncontrollable gum disease).
