Apicoectomy is one of the most commonly performed endodontic surgeries. Though this surgery often results in complete resolution of signs and symptoms of the surgical area like a sinus opening or swellings, it seldom gives a radiographical evidence of bone formation in the surgical site. Guided bone regeneration using particulate bone grafts mixed with Platelet Rich Fibrin (PRF) and barrier membrane can be effectively used for enhancing the predictability of this surgery. A case series of such a few cases are discussed here to bring into light the application of such a technique that take into consideration the wider application of periodontal regenerative techniques.
