Guided Endodontic Micro-Surgery (GEMS): A Novel Approach for a Targeted Apicoectomy—A Report of 3 Cases

Guided endodontic microsurgery, also known as guided is a surgical procedure used to treat failed endodontically treated teeth with periapical infections. microsurgery can be problematic in some situations, such when there are tough anatomical features or limited access. Some of these complex cases managed using cone beam computed tomography imaging, CAD software design, and 3D printing technologies. A stent was manufactured printer each the three cases. Prior surgery, infection location, depth, angulation preparation were determined protect sensitive components. The target location chosen ensure precise root excision avoid during surgery. Infected tip resection biopsy accomplished one step by rotating trephine bur hole. Once retrograde filling completed, bone graft material added site then tissues sutured achieve primary closure. Surgical stents produce effective targeted apicoectomy certain angle depth preparation. In addition, soft tissue reflected protected unique stent.
