When the Bone is Sufficient ...

A 52-year-old woman is a dental phobic.  Her main concern is the tooth #3 with caries apparently involving the furca (Fig.1 ^).  Before extraction, take photos to show a polyp in the pulpal chamber, which is most likely periodontal.  After extraction (prepare surgical handpiece, since the tooth most likely fractures at extraction), take photos to show furcal perforation, while the socket is packed with 3 pieces of gauze soaked with Metronidazole.  There is apparently sufficient bone apical to the roots (Fig.2).  To achieve primary stability, use an implant as long as possible (13 mm of IBS, Fig.3 (implant is drawn to be placed too superficial)) with large diameter appropriate to the septum.  The plateau of the implant will be placed apical to the crests and coronal to the septum.
