A healing abutment is placed at #31 because of supraeruption of the tooth #2 (Fig.4,5), while a cementation abutment is placed at #30 (incomplete seating) with autogenous bone (from drills) and allograft placed around it (*, Fig.6).  However, the miniimplants dislodged.  Due to coronavirus, the implants are restored with heavy abutment and opposing tooth trimming 1 year 9 months postop (Fig.16).  Magicore should have been placed instead.
