A 41-year-old woman returns for #29 and 30 implants (Fig.1,2) because of a fistula mesiolingual of #30 (Fig.3 arrowhead) several years post RCT.  There is no deep pocket at #30.  In fact the distolingual canal is missing (Fig.2 (black arrow),3 (DL)).  RCT retreatment should solve apical periodontitis.  Open white arrow: diastema between #28 and 29.  Mesialization of the tooth #29 is needed prior to implantation, since the mesiodistal space at #29 is narrow (3.5 mm).
