Supraerupted Opposing 2nd Molar

There is about 6mm of clearance between the supraerupted #2 and the implant platform (Fig.8).  Barely enough.  There is plenty of the apical bone at #30 (Fig.9).  It is safe to place a 4.5x11 mm IBS implant.  But the apical bone at #31 is not a lot.  It is better to place 4.5x9 or 10 (UF?) mm implant at #31.  If the bone density is not high at #24 (Fig.10), do not use the last drill fully.
