Long Implant and 5 mm Cuff of Abutment

A 59-year-old man will return for #15 implant placement after the one at #13 (Fig.1).  The bone allows an implant as long as 15-18 mm (Fig.1,2 red line).  His gingiva is as thick as 5 mm, requiring an abutment with 5 mm cuff (Fig.2 pink line).  The bone at #15 does not look dense or the ridge is narrow.  Use #15 and DIO bone expansion kit for osteotomy.  The less density of bone, the longer the implant.  If a 4 mm abutment is long, adjust the opposing supraerupted tooth.
