It is always best to have the castings completed, fig. 36, before the bone impression is taken so that the bridge can be completed as quickly as possible. Over the exposed bone, fig. 37, a cold cure acrylic tray was moulded, figs. 38, 39. The tray was used for a rubber base impression and the impression was picked up with a full mouth alginate impression to determine the paralleling of the implant post with the anterior abutment teeth, fig. 40. The implant with its lingual fingers fitting exactly into lingual grooves, fig. 41.

After the tissue has healed, fig. 42, the unilateral bridge is cemented to place, fig. 43. A lateral plate roentgenograph, fig. 44.
