When a 7x17 mm tap is being inserted, the patient feels pain, possibly related to expanding the weakened buccal plate.  A smaller, but longer implant is finally placed (6x20 mm with insertion torque 55 Ncm, Fig.6).  The shortcoming is that primary closure cannot be achieved over the tissue-level implant, whereas bone-level implants available are too short.
