A new classification of peri implant gaps based on gap location (A case series of 210 immediate implants)

Douglas Deporter, Ali Akbar Khoshkhounejad, Nikfam Khoshkhounejad, Mohammad Ketabi


Based on our collective experiences with gap management around immediate dental implants, we
have proposed a classification of gap type based on the location in relation to implant periphery.
Seven types are proposed, and all but one type should heal without gap grafting provided that
flap‑less surgery and atraumatic extraction have been achieved. The exception is our Type II gap
where the implant has been placed too far buccally leaving a gap only on the lingual/palatal. In this
case, the lingual/palatal gap need not be grafted, but the buccal aspect of the implant should best
to augmented to avoid the complications.
Key Words: Bone graft, classification, immediate dental implant
