Soft Tissue Esthetic With Autogenous Dentin Chips and Immediate Implantation Versus Conventional Immediate Implantation With Xenograft in Thin Buccal Bone

Recently augmentation with bone grafting became one of the most common techniques surgically ; progressive bone resorption may be prevented by using augmentation procedures with use of graft materials. The gold standard in regenerative procedures is autogenous bone graft because of osteoinduction , osteoconduction and osteointergration properties required in regeneration. In autogenous bone graft there is need for a second surgical site , donor site morbidity and limited availability will lead to challenge for alternative bio-materials.

Extracted healthy non functional teeth from human are considered to be a dental waste all over the world. High proportion of extracted sockets are left untreated for physiological healing. Inadequate or failure of bone healing in sockets has been seen due to absence of bone graft material. Stem cells, matrix , trace metal ions and growth factors are rich in human tooth. Bone and dentin tissue structure are different but ratio of components is similar (mineral 70% , collagen 20% and body fluid 10% by weight). Dentin after demineralization is mainly composed of type 1 collagen 95% and non collagenous proteins as growth factors.
