For safety, this case should have had a large cylindrical (Fig.7) or the least tapered (Fig.8) implant placed to occupy the cylindrical socket.  No drills are used for new bone.

The precaution to be taken for the large non-tapered implant is to protect the buccal plate while it is being placed.  Lean the implant as lingual as possible.  Bone graft where necessary.

No Drill Implant Placement Last Next
