Margin and Gingival Embrasure
The mesial embrasure of the implant crown at #19 is excessive and may collect food (Fig.1,4 *). In fact the crown margin is shy of prep margin (Fig.2,5 ^). If the crown margin extends to what it should, the gingival embrasure should be able to be closed (Fig.3,6).
The case should be redone.
In the future, close the gingival embrasure as much as possible. If the margin is too supragingival, extend the margin apically a little bit.
