Streamlining and simplification of surgical stent fabrication for micro‐endodontic surgery

Abstract

Surgical stents allow clinicians to undertake micro‐endodontic surgical procedures with an increased level of accuracy. When planned in combination with cone‐beam computed tomography (CBCT) radiographic imaging, surgical stents can help accurately determine the point of entry of the surgical drill, minimise the size of the osteotomy, ensure accurate resection of the root/s and avoid vital anatomical structures. Fabrication of surgical stents can, however, be a complex and long‐drawn‐out process, adding to the cost of the surgery. This case report presents a relatively easy method of fabricating a surgical guide and showcases the benefits of a planned surgical guide in managing a periapical pathology with close proximity to the mental nerve canal.

New-designed 3D printed surgical guide promotes the accuracy of endodontic microsurgery: a study of 14 upper anterior teeth

“…With the development of modern digital technologies such as 3D imaging, CBCT, and CAD/CAM, there have been some achievements in the clinical application of 3D printed surgical guides in apical surgery, realizing the precise positioning of the root apical lesion area, the reduction of surgical trauma and the protection of adjacent tissue structure to a certain extent 6 – 8 . At present, research on digitally guided endodontic microsurgery mainly focuses on individual case reports 9 – 11 . In the current studies, there are 3 types of apical surgery assisting guides: localized bone-removing guide, fixed-depth bone-removing guide, and localized fixed-depth bone-removing guide 12 – 18 .…”
