When the tooth #3 with severe buccal gingival recession is extracted and implants are placed at #3 and 4 with guide, sticky bone in 2 large pieces is packed between these implants with a previously large defect in a seemingly secure manner (Fig.1 *). Use of a longer implant at #3 (11.5 mm vs. 10 mm with more coronal placement) will reduce the chance of abutment screw loosening in the future. The implant at #3 is placed in the palatal socket without apparently no sinus lift.
