A 4.5x14 mm implant is placed with insertion torque >60 Ncm (Fig.5). The implant remains lingual, whereas there is an approximate 3 mm buccal gap, which will be bone grafted.
The implant plateau is at the most coronal crest level and approximately 2-4 mm from CEJ of the neighboring teeth. The crestal defect is expected to heal with bone graft.
Fig.9: 2 months postop. T: temporary abutment. Bone appears to deposit mesial to the implant.
The temporary abutment is loosened 6 months postop; there is no apparent bone regeneration mesial and distal to the implant (Fig.11 *).
Fig.15: The coronal threads appear to be not covered by the bone (arrowheads) 18 months postop (12 months post cementation) with gingival hemorrhage.
