The alveolar bone undergoes a remodelling process after tooth extraction, which leads to horizontal and vertical bone loss. These resorption processes complicate dental rehabilitation, particularly in connection with implants. Clinical studies have suggested that retaining roots of hopeless teeth may avoid tissue alterations after tooth extraction. The aim is to seal the surgical site following the outline of extraction socket and to develop an ideal prosthetic emergence profile, modelled on the anatomy of the existing tooth. In present case report a non restorable mandibular molar was treated with socket sealing protocol followed by immediate implant placement. Using sequential osteotomy drills implant site was prepared and roots were dissected in buccolingual direction along the long axis. Roots were extracted using elevators and implant of desired size was placed. A Customized sealing socket abutment (SSA) was prepared to support the coronal emergence profile of the tooth. This technique is a minimally invasive that can preserve the hard and the soft tissue contour of the ridge.
