“…To prevent errors introduced in the delineation of the dental anatomy, all segmentation was performed and verified by an experienced radiation oncologist before conversion to an STL mesh. Design of the oral stent was performed using Autodesk Meshmixer which is a free albeit powerful 3D modeling and sculpting software that has been used to make high-fidelity patient-specific coronary vasculature and dental models [ 16 , 17 ]. Printing of the final device was performed using the Form2 desktop SLA printer which is approved for dental applications with 3D printed objects demonstrating dimensional accuracy within 50–100 μm.…”

BackgroundOral stents have been shown to reduce the deleterious effects of head and neck radiotherapy through the displacement of normal tissues away from the areas of high dose irradiation. While these stents are commonly used in the treatment of patients with head and neck cancer at many large academic cancer centers, their use is much more limited outside of these institutions due to the time and expertise required for their fabrication.ResultsIn the study, we describe a novel method to design and manufacture oral stents from routine computed tomography (CT) imaging studies through the use of 3D printing technologies.ConclusionOur proposed method may help to greatly expand access to these beneficial devices for patients undergoing radiation treatment at centers without access to dental and oral/maxillofacial specialists.

“…Personalized scaffolding technology has been increasingly used in the alveolar ridge reconstruction for the implant site development. 3D‐printed diagnostic models and preoperative templates are widely applied for ridge augmentation in severe vertical and horizontal bony defects . Despite the advanced applications of CBCT combined with CAD/CAM fabrications, current 3D printing for alveolar ridge augmentation is limited using printing templates, which might not directly induce bone regeneration as inert biomaterials.…”

“…3D-printed diagnostic models and preoperative templates are widely applied for ridge augmentation in severe vertical and horizontal bony defects. 32,33 Despite the advanced applications of CBCT combined with CAD/CAM fabrications, current 3D printing for alveolar ridge augmentation is limited using printing templates, which might not directly induce bone regeneration as inert biomaterials. Considering its clinical potential in other specialties, future directions suggest applying 3D technology using osseoinductive and osteoconductive biomaterials will better enhance bone and tissue regeneration for vertical and horizontal ridge augmentation supporting implant placement.…”

Structured Abstract The reconstruction of alveolar bone defects associated with teeth and dental implants remains a clinical challenge in the treatment of patients affected by disease or injury of the alveolus. The aim of this review was to provide an overview on advances made in the use of personalized scaffolding technologies coupled with biologics, cells and gene therapies that offer future clinical applications for the treatment of patients requiring periodontal and alveolar bone regeneration. Over the past decade, advancements in three‐dimensional (3D) imaging acquisition technologies such as cone‐beam computed tomography (CBCT) and precise scaffold fabrication methods such as 3D bioprinting have resulted in personalized scaffolding constructs based on individual patient‐specific anatomical data. Furthermore, ‘fiber‐guiding’ scaffold designs utilize topographical cues to guide ligamentous fibers to form in orientation towards the root surface to improve tooth support. Therefore, a topic‐focused literature search was conducted looking into fiber‐guiding and image‐based scaffolds and their associated clinical applications.

“…As a result, the bone graft more accurately reconstructs the missing alveolar ridge. 34 Combining laser scanning of gums and teeth over CAD imaging from CT allows for accurate fabrication of dental implants as it provides a more accurate relationship between soft tissue and bony structures. 35 When applied as an intraoperative guide, a case series of 12 patients requiring C1-C2 fusion benefitted from use of a personalized 3D printed template, as all 48 screws were appropriately placed with 0.7 ± 0.4 mm variation from simulated and preplanned trajectories.…”

There is level IV evidence to support the use of 3D printing for education, pre-operative planning, simulation and implantation. In order to make this technology widely applicable, it will require automation of DICOM to standard tessellation language to implant. Advances in knowledge: Recent lapses in intellectual property and greater familiarity with rapid prototyping in medicine has set the stage for the next generation of custom implants, simulators and autografts. Radiologists may be able to help establish reimbursable procedural terminology.
