The flexible gingival mask: an aesthetic solution in periodontal practice.

Dramatic aesthetic results have been obtained with the flexible silicone gingival mask which can be used to correct deformities remaining after destructive periodontal inflammation has been controlled. The silicone mask may also be used as an interim measure to improve the appearance of anterior crowns after initial periodontal therapy to allow time for healing and the establishment of periodontal stability and prognosis. A simple two-stage impression technique is described, enabling a suitably trained dental technician to produce comfortable and accurately fitting masks, which are very stable during use. Virtually no problems have been encountered.
