Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
There are some bone augmentation techniques known and used for this purposes, including: guided bone regeneration (GBR), distraction osteogenesis, split osteotomy, onlay bone graft, and interpositional bone graft.
One of the techniques is the interpositional bone graft using "sandwich osteotomy" technique, in which a cut is made in the bone (one horizontal and two vertical) separating a mobile bone portion which is fixed (using bone plate) in its new "ideal" position. The gap between the moved bone and the remaining bone is filled with xenograft ("bio-oss"). There is no documentation in the literature about histological evaluation of the bone after this well known clinical procedure. Four months after the bone augmentation procedure - the fixating plate is moved out and dental implants inserted. The first bur of the implantation (the smallest in the diameter) will be a trephine from which a histologic slide will be taken for check. The continuous dental implants insertion is the normal protocol for dental implantation (widening the recipient hole with bur, and insertion of the implant), followed by rehabilitation by prosthodontics.
