Hemisection with socket preservation using Platelet Rich Fibrin [PRF] - A case report with one year follow up

Abstract

With advances in dentistry as well as the increased patients' desire to retain their natural teeth, there is a paradigm shift from extraction to the preservation of teeth. Mandibular first molars are the primary occlusal load-bearing teeth, commonly extracted teeth due to dental caries and periodontal disease. Hemisection is a conservative alternative to retain a hopeless tooth. Following endodontic treatment and selective root removal, the remaining portion of the tooth is splinted to the adjacent teeth with a fixed partial denture prosthesis. The resorption of the alveolar ridge surrounding the extraction socket may complicate the subsequent prosthetic procedure. Hence, socket preservation technique evolved, which prevents such untoward changes in the extraction socket. This case report shows hemisection procedure in a grossly carious first mandibular right molar with furcation involvement of a healthy 40-year-old female patient followed by autologous platelet-rich fibrin placement in the extraction socket. One year follow-up showed little alveolar resorptive changes with better healing and function clinically.
