The Use of advance Platelet-Rich Fibrin during Immediate Implantation for the Esthetic Replacement of Maxillary Anterior Segment with Chronic Apical Lesion

Objective: To observe the clinical effect of immediate dental implants apply to the chronic apical lesions after tooth extraction with the advance platelet-rich fibrin (A-PRF). Methods: six cases with chronic apical lesions, after removal of teeth and completely clear the infection lesions found there were buccal bone defects. Then all patients accepted immediate dental implant combine with A-PRF fragments filling the bone defect area and covered by PRF membrane. There month later, the final restoration were finished. Result: 1. All the cases achieved good clinical efficacy. No case of infection or implant failing.2. Three months and six-month follow up, imaging studies showed the osteogenesis well. Pink aesthetic implant the desired effect, in all cases pink aesthetic score reached 10 points or more. Conclusions: Advance Platelet-rich fibrin (platelet-rich fibrin PRF) in patients with chronic apical lesions after tooth extraction performed immediately before planting earlier clinical success rate of bone graft, anti-infective ability, more effective, aesthetic effect can be expected, is one worthy of immediate implant bone grafting methods.
