After extraction of #24, the initial osteotomy is close to the tooth #23 clinically; after establishing a 2nd osteotomy, it is close to #25 (Fig.2).  Lindamann bur is able to change osteotomy to acceptable degree (Fig.3), but the dummy implant (3x14(2) mm) tilts buccally clinically. Ideally a new osteotomy should have been created (Fig.13 red arrow) once the initial drill is withdrawn (black area).
