If the tooth #4 is nonsalvageable (Clindamycin), two implants will be placed at #3 and 4 (Fig.2). Take intraop PAs as early as possible for trajectory confirmation. Since the ridge at #3 is wide (Fig.3, coronal section (B; buccal)), use Magic Split to start osteotomy, followed by Magic Expanders. The initial depth at #3 will be 12 mm and gradually increase to 14 mm. On the other hand, the bone density is higher at #4, drills will be used for osteotomy. Speed will be reduced at 50 RPM when the drills are more than 3.8 mm.
