The clinical success and periodontal evaluation of patients rehabilitated with light-cured obturators.

The clinical performance of a visible light-cured (VLC) resin for obturators was evaluated in 10 patients. All patients had undergone ablative surgery of the maxilla, previously worn conventional heat-cured hollow bulb acrylic obturators and were currently rehabilitated with VLC obturators. The obturators were assessed on their performance for each of the following: weight, retention, speech, eating and comfort. An evaluation of the periodontal status of those who retained teeth in the maxilla was also performed. It is concluded that patients found VLC obturators to have a more acceptable clinical performance than conventional acrylic obturators due primarily to a reduction in appliance weight.
