Summary

This study will be conducted to compare the effect of Erythropoietin gel mixed with xenograft versus xenograft alone in grafting the jumping gap around immediate implant.

Detailed description

The distance between the implant and the defect's surrounding wall is known as the horizontal bone defect (also known as the "Jumping Distance" or "Gap"). By filling the space between the implant and the buccal bone walls of recently extracted sockets, bone grafting material promotes hard tissue repair and reduces marginal bone loss. To increase bone contact to the implant surface and lessen gingival recession brought on by horizontal bone resorption, bone grafting at the gap is advised. Various methods have been employed to bridge the gap in bone: autograft and allograft-based bone substitutes, which can be utilized separately or in conjunction with other materials like freeze-dried bone, xenograft (like bovine bone), and ceramic-based bone graft alternatives like calcium phosphate, calcium sulphate, and bio-glass. According to a study by Bianchi S, using xenografts improved the osteoconductive qualities of bone regeneration by demonstrating significant cellular activity. The potential of EPO to enhance bone growth and tissue protection by reducing ischemia and inflammatory responses is one of its non-hematopoietic properties. EPO stimulates the development of mesenchymal stem cells (MSCs) into osteoblasts and participates in the interactions of osteoblasts and osteoclasts to promote bone formation.
