A new osteotomy is created in the palatal wall of the existing implant site with 2 mm pilot drill, followed by 2.5 and 3 mm reamers. As a 4.5x17 mm tap is being inserted (Fig.6 T), it is deviated buccally. Reamers are re-used to try to remove more palatal bone to let the implant be placed more palatally. A 4.5x17 mm tissue-level implant is placed (Fig.7 I with insertion torque >60 Ncm). A: 20° angled abutment.
