Socket Preservation for Intact Walls M

A 65-year-old man cracks 3 teeth in ~2 years (Fig.1,2 (#4,13,15)).  The tooth #4 is symptomatic after RCT (Fig.1); it appears that the buccal canal is incompletely filled (data not shown).  In fact an exam 1 month later shows that the symptomatic tooth is #2 (crack), while #4 is salvageable (Fig.8).  The tooth #13 has palatal subgingival fracture with severe pain (Fig.2 with palatal defect).  In fact the title of this case is incorrect).  After extraction, allograft is placed (Fig.3 *) with 6-month membrane.  In fact the bone graft is not packed into the apex of the socket; a condenser should have been used.  The patient returns 3 days postop before leaving abroad.  The 6-month membrane remains in place (Fig.4), while the ridge at #15 is minimally atrophic (Fig.5).  The coronal lamina dura becomes indistinct 5 months postop (Fig.6).  The bone graft remains in the socket.  The distoapical portion of a 4x11.5 mm implant may be in the sinus (Fig.7).
