title: Rehabilitation of post surgical maxillectomy defects using interim obturators-a case series.
abstract: Prosthetic rehabilitation of extensive maxillectomy defects are exigent given the difficulties faced due to loss of palatal bone,teeth and surrounding supporting tissues which help in retention, support and stability of the prosthesis. An interim maxillary obturator is a prosthesis which is made after surgical resection of a portion or all of one or both maxilla where initial healing is completed. Frequently many or all teeth in the defect area are replaced by this prosthesis. It plays a vital role in preventing the facial disfigurement and irritation to the surgical site thereby enhancing the healing and restores the functional capabilities such as speech, mastication, deglutition etc. To gain better retention and stability, preservation of the unaffected regions is needed which can be achieved by proper surgical planning and designing of the prosthesis. This case series describes rehabilitation of three extensive maxillectomy defects with hollow open and closed interim obturators.
