After removing the shorter parallel pin in Fig.2, osteotomy at the site of #4 extends to 14 mm, followed by 2.6 mm (14 mm deep) and 3.0 mm (7 mm deep) expanders. Both of them are stable, but a 3.5x17 mm tissue-level 1 piece implant has less than 15 Ncm insertion torque. The implant is then placed at the site of #5 with insertion torque between 40 and 45 Ncm (Fig.3: #5). To achieve primary stability at the site of #4, the osteotomy is extended to 17 mm with the 2 mm pilot drill (#4).
