The last two drills for sequential osteotomy are 4.3x13 and 4.8x11.5 mm.  A 5x11.5 mm UF implant is placed slightly subcrestal with insertion torque > 50 Ncm (Fig.2).  Following placement of 6.5x2 mm healing abutment, the opposing tooth needs adjustment for height.  Orthodontic intrusion of the opposing tooth is scheduled 2 days later.  It is accidental to find root fracture of the mesial root of the tooth #30 (Fig.1 <).  There is minimal bone resorption coronally 5 months postop (Fig.3).  A provisional is fabricated at #31 to assist in intrusion of the tooth #2.
