Osteotomy in Mesial Slope

A 64-year-old woman will return for extraction/implant for the upper left 2nd molar with a fistula (Fig.1).  Since the roots deviate distal (Fig.2 after extraction), initiate osteotomy in the apical 1/3 of the mesial slope with 1.5 mm drill (Fig.3).  Once the lamina dura is penetrated, change trajectory (Fig.4) and extend depth for 15 mm (gingival level).  After use of 2 mm drill, insert marked parallel pin for PA.  The final implant as well as abutment is shown in Fig.5.
