“…Despite this, relatively little has been said in the literature about the use of such modern methods for root end localization and resection. The few available studies agree that guided root-end resection is efficient and more accurate than freehand surgery [23, 24]. To our knowledge, we are the first to report a series of clinical cases where osteotomy and root-end resection were carried out at the same time, with the same instrument (a bone trephine), using 3D printed surgical guides.…”

BackgroundRoot-end resection is an endodontic surgical intervention that requires high precision so that all ramifications and lateral canals so as infected tissues are eliminated. An exploratory study was conducted to justify the clinical safety and accuracy of guided root-end resection with a trephine.MethodsFourteen root-end resections were performed in 11 patients. With the aid of computer tomography and rapid prototyping a stereolithographically fabricated, tooth-supported surgical template was used to guide trephinations. Surgery was performed using the printed surgical stent and a trephine was used not only for the osteotomy but for the root end resection as well.ResultsThe root end was successfully and completely resected by the trephine in all cases. No intraoperative complications were observed in any of the cases, and the patients were free of symptoms indicating recurrence or complications at the 6-month follow-up. The median angular deviation of the trephination was 3.95° (95% CI: 2.1–5.9), comparable to the angular deviation of guided implant surgery. The mean apex removal error (ARE) was 0.19 mm (95% CI: 0.03–0.07). The mean osteotomy depth error (ODE) was 0.37 mm (95% CI: 0.15–1.35). Overpenetration was a characteristic finding, which indicates the necessity of a stop-trephine.ConclusionsWithin the limitations of this study, we conclude that our results support the use of guided trephination for root-end resection.

“…The location of the root apex can be challenging when the periapical pathology has not perforated the cortical plate. Ackerman et al (2019) reported a mean deviation of 1.78 mm when using surgical guides to access the apex of roots in a human cadaver study model (11). The accuracy was reportedly significantly better than that procedure undertaken without the use of a surgical guide (11).…”

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

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.

Conservative management of Type II dens invaginatus with guided endodontic approach: A case series

2019

View full text Add to dashboard Cite

Dens invaginatus (DI) is one of the rare malformations of teeth which results from an infolding of the dental papilla during the development of teeth. This defect gives rise to a possible communication between the pulp and oral environment, thereby increasing the susceptibility to caries, pulpitis, and pulp necrosis. Thus, early detection and conservative management of this invaginatus is of utmost importance. The present case series describes a conservative endodontic treatment technique for the management of teeth with Type II DI using a guided endodontic approach with three-dimensional printed surgical stents. This technique provides a precise and minimally invasive approach in the conservative management of DI, without compromising the vitality of main pulpal tissue.
