Core Tip

Core Tip: This article provides up-to-date knowledge regarding the clinical presentation, incidence, risk factors, diagnosis, and management of implant fractures. Conventional treatment requires that the apical portion of the fractured implant be visible. For deep and invisible implant fractures, the traditional trephine method has been ineffective. We developed a novel method of osteotomy combined with the trephine technique that can effectively address deep and invisible implant fractures. Meanwhile, modified Wafer technique-supported guided bone regeneration treatment was conducted simultaneously to preserve the bone mass in the surgical area.
