Evaluation of Secondary Dental Implant Stability Utilized For Narrow Ridges With Injectable Platelet Rich Fibrin Versus Straightforward Cases
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.
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

Complicated cases according to SAC classification.
Patient with signs of acute infection and purulent exudates at the site of implant placement as revealed by clinical and radiographical examination.
