After extraction and socket debridement and disinfection, sequential osteotomy is carried out free hand. The first intraop PA is taken quite late in osteotomy. When a 4.5x17 mm tap is inserted 14 mm deep, the apical end of the tap is close to the roots of the tooth #2 (Fig.5), although its coronal end is in the middle of the edentulous area (red lines).
