Multirooted tooth guided immediate implant placement in molar sites: a report of two cases

Post extraction immediate implant placement in multirooted molar area is a challenging task in view of anatomical limitations of the socket and in achieving primary stability after ideal placement of the implant along the interradicular septa. The aim of this article is to present a technique of tooth guided implant site preparation for immediate implant placement in multirooted molar areas. Coronal portion of the concerned tooth was reduced to the level of marginal gingiva, osteotomies were performed using centre of the remaining tooth root complex as the reference point and the implant bed is prepared engaging the interradicular septa. The remaining tooth root complex after complete implant site preparation is atraumatically removed and the fixture is placed directly in the prepared implant site thus allowing the precise placement with proper angulation. This technique helps the surgeon in ideal implant positioning in immediate implant placement cases as it prevents slipping of the drills in mesial or distal root sockets during initial osteotomies and allows stabilized and guided implant placement.
