Overprep
After placement of implant at #30 with high torque, osteotomy is prepared with 2.2 mm drill at #24 (M) first (Fig.1 before flap surgery). A 2.5 mm mini implant is placed < 10 Ncm (Fig.2,3). Since the ridge at #26 is apparently wider than that of #24 (Fig.1), a 3x11.5 mm implant is placed after the same drill (2.2 mm); insertion torque is ~ 35 Ncm. Bone graft is placed around the implants (Fig.2,3 *) before placement of PRF membrane. The patient is unpleased with our being unable to fabricate an immediate provisional (because of low torque at #24) as we have promised to. He is going to attend a wedding in fortnight. Instead periodontal dressing is applied. The latter is slight loose 1 week postop (Fig.4). There is apparently no bone loss 4 months postop with ~ 3 month provisional (Fig.5). The gingiva is healthy in spite of poor oral hygiene.
