After extraction of the 3rd molar with mesial periodontal defect, osteotomy for 2nd molar implant is initiated in the mesial slope of the 3rd molar socket (Fig.2). When osteotomy is finished with IS drills and sinus lift with Magic Sinus Lifter (S-reamer with 11 mm stopper being short), a 4x10 mm dummy implant is placed with ~ 4 implant thread exposure (Fig.3 (red line: socket)).
