Abstract
Comparitive Study of Immediate Implant Placment Using Autografts and Nanoparticles
Highlights
Dental implants is the replacement of missing teeth long lasting treatment modality providing functional and esthetic integrity,making dental implants treatment more advanced and ameliorated[1]
Grafts are widely used in immediate dental implants for stability and deficiency of bone. grafts may be autogenous bone grafts or hydroxyapatite nano particles bone grafts
In immediate implants after extraction of the teeth preserving the buccal bone the implant will act like a pole to hold the surrounding bones for the primary stability and give its functional requirements necessary to prevent it from undergoing atrophy, but in times it is impossible to regain the primary stability of immediate implants because of bone deficiency due to many factors like infection, trauma from extraction, size discrepancy between the tooth that is extracted
Summary
Dental implants is the replacement of missing teeth long lasting treatment modality providing functional and esthetic integrity ,making dental implants treatment more advanced and ameliorated[1 ]. Grafts are widely used in immediate dental implants for stability and deficiency of bone. Grafts may be autogenous bone grafts or hydroxyapatite nano particles bone grafts. Hydroxyapatite (HA) nano particles has been widely used as a biocompatible bone graft, mainly for contact with bone tissue, has resemblance to mineral bone. Presents a carbonated and partially substituted apatite, based on nanocrystal aggregates, and associated with collagen, building up 3-D structures present in various bone tissue conformations like trabecullar or cancellous bone. Autogenous bone remains the “Gold Standard” for grafting. The nanomechanical properties of the surrounding bone were evaluated by nanoindentation. While both implants revealed similar bone-to-implant contact, the nanoindentation demonstrated that the tissue quality was significantly enhanced around the HAcoated implants, validating the postulated hypothesis
