In situations where many periodontally involved teeth have to be extracted, fig. 127, leaving the mandible totally edentulous then at least six months must elapse before re-entering the area to insert bladevents, figs. 128, 129, 130. Fig. 131 shows the fabricated restoration, again with a pink gum-line. It is then fitted and cemented, figs. 132, 133, 134. The final x-ray, fig. 135.

Often only four protruding posts can be used, instead of the usual six, fig. 136, to support a full arch splint, fig. 137. In order to build out the lips a snap-on pink acrylic stent was fabricated, fig. 138, which was removed after meals.
