Allograft Fills in Defect

Pre-operative PA shows root tip fracture of the tooth #25 (Fig.1 <).  After extraction, the defect is evident (Fig.2 arrowheads).  Clinically there is no lingual plate, whereas the buccal one is low.  Allograft fills in the defect (Fig.3 *) following placement of a 3x16(4) mm 1-piece implant with insertion torque >50 Ncm.  Later the implant is placed deeper to reduce possibility of periimplantitis.  With scaling & root planing, the gingiva around the provisional is healthy 3 weeks postop (Fig.4 P).  The bone graft persists in the socket 4 months postop (Fig.5).  Implant threads seem to be covered by the bone, as revealed by CT taken 8.5 months postop; 4 months post cementation (Fig.6).
