Overdentures
06 September 2015
Mrs L. attended the unit in February 2006. She was extremely unhappy with her complete dentures, which she had been wearing for two years. Her main concerns were the unstable lower denture, loss of confidence, sagging of facial tissues and associated discomfort.
 
Examination revealed her lower denture to be very unstable due to the advanced resorption (gum shrinkage). This means that her lower jaw gum was flat and the denture had very little to support it. Following radiographic investigation and a combined appointment with both the surgeon and the prosthodontist, Mrs L. agreed to undergo implant treatment to resolve her problems at the same time enrolling herself on a research project to study immediate function of dental implants.

The prosthodontist, over a series of appointments, prepared a new set of dentures to the try-in phase, that is, the penultimate phase of denture fabrication. Great care was taken to ensure that the new denture met the patient’s expectations regarding tooth position, colour and facial soft tissue support. The unfinished lower denture was used to help the surgeon insert the two lower implants in the optimum position. Surgery was performed under local anaesthesia, small circular incisions were made using a special ‘punch’ in the correct position and the bone was then prepared to receive the implants. Two implants (Fixture Original, Branemark Integration, AB, Sweden) were inserted, the final torque (stability) being very good indeed. Multi-unit abutments (the second part of an implant that traverses the gum) were immediately fitted and impressions were obtained by the prosthodontist.
 
The laboratory technician cast the models and soldered a gold bar between the implant abutments. The new lower denture was then completed, incorporating clips within its base. Once polished up, the gold bar was secured intra-orally onto the implants and the denture clipped into place. The new upper denture was also fitted.

Nearly four years have now gone by, the patient maintains her implants and dentures impeccably well. She reports that her lifestyle has changed, for the better, that she is able to eat anything she wishes comfortably and that she feels as though she had a face lift.

Every day, people look into getting dentures as a way to improve their smile and overall health. Natural teeth can be lost due to decay, periodontal disease (gum disease) and injury. Along with the lost teeth, the bone supporting the missing teeth will be resorbed (shrinks).
