In spite of using Lindamann bur to remove the bone from the buccal portion of the osteotomy, the apical end of a 5x9 mm dummy implant slides into the palatal socket with the coronal end placed as buccal as possible for restoration (Fig.2). Further use of Lindamann bur for buccal bone removal is not feasible, since the buccoapical portion of the osteotomy starts to be perforated with apparently intact sinus membrane.
