Prior to placement of a 7x14 mm implant (Fig.8 I: >60 Ncm), a piece of Osteotape (collagen membrane saturated with Osteogen, a type of Hydroxyapaptite) is placed against the lingual defect, followed by bone graft lingually. More bone graft is placed in the peri-implant gaps (*) proximally post implant placement.
Four months postop, bone graft remains attached to (Fig.20 >) the rough (R) and thread (T) surfaces of the implant, while moving away from (<) the smooth (S) surface. This is what it should be. A: abutment.
