Guided biopsy of osseous pathologies in the jaw bone using a 3D-printed, tooth-supported drilling template


Valdec, Silvio; Schiefersteiner, Mona; Rücker, Martin; Stadlinger, Bernd (2019). Guided biopsy of osseous pathologies in the jaw bone using a 3D-printed, tooth-supported drilling template. International Journal of Oral and Maxillofacial Surgery, 48(8):1028-1031.

Abstract

Suspicious radiological findings in the jaw bone require histopathological examination for the confirmation of a diagnosis. As pathologies in this region are difficult to reach or are in close proximity to relevant anatomical structures, e.g. tooth roots or nerves, they often represent a challenge. Such factors may adversely affect the predictability of the surgical outcome of a biopsy of the osseous tissues. This technical note introduces a novel method for performing a digitally planned, guided biopsy. For this purpose, a cone beam computed tomography scan and an intraoral scan are superimposed using specific planning software. The resulting three-dimensionally printed, tooth-supported drilling template is designed for a trephine biopsy. It allows a precise, minimally invasive approach, with an exact three-dimensional determination of the biopsy location prior to surgery. The risk of devitalization of the neighbouring teeth or possible damage to the nerve structures can be minimized. Furthermore, a small access flap can be sufficient. In summary, the method of bone biopsy presented here allows high precision and greater predictability for biopsy sampling and is minimally invasive for the patient.
