23 dentistry 4_2016 cosmetic restorations would be fabricated according to the other silicone index, in which the im- provement of the aesthetic outcome could be observed clearly. However, the shape of the provisional restorations was not de- signed to emulate the erupted natural teeth, but for the cervical part of the restorations to cover the labial gingiva. After a long pe- riod of remodelling and reshaping, the form of erupted natural teeth would be estab- lished (Figs. 22 & 23). The impressions for the post and cores were taken at the same time. Because the restorations were labially inclined, a gold alloy post and cores was chosen. _Shaping the gingival contour The patient attended a follow-up two weeks after placement of the provisional restorations. At that time, the intra-oral examination showed re- cession of the gingiva and exposure of the shoul- ders on the labial side of both tooth #21 and tooth #12 (Fig. 24). The margins of tooth #11 could also be observed and the gingiva was healthy. At this appointment, the post and cores were placed and further tooth preparation was carried out to shift the margins in the apical direction. The new provisional restorations were fabri- cated to increase the convexity of the cervical part in order to enhance the effect of the gin- Fig. 30_Once the second provisional restorations had been removed, the ideal gingival contour could be observed.
