A novel technique for making impressions in maxillectomy patients with trismus
Making impressions for obturator prosthesis may be hindered by limited oral opening as a result of postsurgical scarring, trismus, fibrosis of the muscles of mastication after radiation therapy, size and extension of the defect, or a combination of these factors. Maximizing the lateral peripheral contour is necessary to increase retention and reduce displacement of the prosthesis. This procedure is even more challenging when the patient suffers from trismus. This article describes an impression technique for maxillectomy patients with limited mouth opening.
