Alveolar bone condition in retained teeth region of patient with complete lower overdenture - case report

Abstract

In everyday dental practice, prosthetic treatment of patients having a small number of remaining natural teeth is more or less common and the remaining teeth are kept for improvement of retentive abilities of removable prosthodontics. The essence of the concept discussed herein is that the remaining teeth are to be left in place for purpose of preservatingof the alveolar bone and providing permanent and stable support for complete dentures. Patient M.J.,female had an edentulous upper jaw and 3 remaining lower incisors. After adequate preparation-endodontic treatment, as well as parodontal treatment, clinical crowns were reduced, and then cast cap crowns positioned on parts of dental tissues. Finally, the upper complete denture and lower overdenture were positioned. After the positioning of dentures, a special retroalveolar film holder was placed, dental retroalveolar radiographs were positioned and radiographs were made. The holder was designed to provide intraoral radiograph in selected repeatable positions of radiographs and in the same conditions- standardized procedure, so that it was possible to compare radiograms. Measurements were made on each film for each tooth from its mesial, as well as distal sides, between apexes and coronal borders of alveolar bones. Patient M.J. received dentures and the first radiograph was made at the baseline when cast cap crowns and dentures were positioned in her mouth. Followe-ups were in an identical mode of radiograph and assessing radiographs after 1, 7 and 12 years. We concluded that we achieved a maximum therapeutic effect in such a long period of time. The influence of patients' motivation and better ability to persist in keeping and maintaing oral higiene were main factors for success

Overdenture in terms of preparation and restoration of supporting teeth: Review report

“…Long term monitoring of patients rehabilitated with the OD by implementation of the above-mentioned restoration procedures recorded a low level of tooth loss, about 10%, at the end of the studies 3,4,24,30,31 .…”

“…Considering less favourable aesthetic solution of ODʼs, they are indicated with extreme wear of tooth substance (bruxists, some professions) 23 . ODs may be indicated in cases of extreme tooth wear because it is the easy way to increase the vertical dimension of occlusion 24 .…”
