the main aim of the study is to evaluate the secondary implant stability when using dental implants with injectable platelet rich fibrin accompanied by non-autogenous bone graft material in narrow ridge cases versus straightforward ridges , in clinical comparative study.~Study design:~Forty implants will be installed for this prospective clinical study, the implants will be equally divided into two groups.~Group A (control group) in which the implants will be installed in a straightforward cases.~Group B (study group) in which the implants will be installed by utilizing injectable PRF with non-autogenous bone graft material in narrow ridges.~Preparation of Injectable Platelet Rich Fibrin for the narrow ridge cases is as following:~Five ML of autologous blood to be collected from the forearm (median cubital vein \ cephalic vein \ basilic vein ) by needle gauge with a 5mL sterile syringe without anticoagulant. The entire blood is moved to a 5 milliliter plastic tube, directly centrifugated for 3 minutes at 700 rpm/min at room temperature. A liquid form ( Injectable PRF ) is then achieved on top of the tube just and the red corpuscles at the bottom. Subsequently, the Injectable PRF liquid form is collected from the tube by a sterile plastic syringe, Then it will be mixed with non-autogenous bone graft waiting for 4min, and applied in the area with narrow ridge( deficiency in the horizontal bone width ) .~Follow up Twenty four weeks after surgery , The uncoverage surgery is done under L.A using a tissue paunch for installing the healing abutment ( gingival former ) , Then the secondary stability of implant (Osseointegration) is to be measured using the (Anycheck ) device , and comparing the 2 groups
