One must be careful when reflecting the tissues of a patient whose mandible contains a "labial roll over", fig. 232. Very often if not careful the tissues that are reflected beneath the labial bulge can be torn, thus slowing down the healing mechanism. In this case, however, a clear reflection was possible, fig. 233. Blades were symmetrically inserted, fig. 234. Healing was uneventful, fig. 235. An elastic impression of the posts was taken, fig. 236, for the casting of a one piece superstructure, figs. 237, 238, 239 and to accommodate the processing of acrylic teeth, figs. 240, 241. This x-ray was taken seven years post-operatively, fig. 242.
