“…Dumbach et al reported a reconstruction technique in which they used a titanium mesh tray and autologous iliac bone marrow (particulate cancellous bone and marrow [PCBM]). Preformed trays have been replaced by custom‐made trays, and some clinical usefulness has been reported . The advantage of PCBM transplantation over autogenous free bone grafts is that the postoperative injury at the donor site is mild and special surgical procedures such as microsurgery are not needed …”

“…With 3D printing technology, various surgical templates can be easily fabricated to guide precise reduction intraoperatively. [8,10] With the assistances of these technologies, the therapeutic outcomes have become more reliable and predictable. Currently, these technologies have been attempted in multiple maxillofacial surgery areas, including head and neck reconstruction, [11,12] orthognathic surgery, [7] and maxillofacial trauma.…”

“…Then, with the advances of computer-assisted design and rapid prototyping technologies, precise model of individual patient's mandible could be easily fabricated preoperatively, and titanium mesh could be manually adapted to make more precise trays. [1,8] But, in general, these customized mesh trays are still hand-fabricated utilizing prefabricated commercial titanium mesh. It is time-consuming to achieve a precise contour.…”

Rationale:Precise bony reduction and reconstruction of optimal contour in treating comminuted mandibular fractures is very difficult using traditional techniques and devices. The aim of this report is to introduce our experiences in using virtual surgery and three-dimensional (3D) printing technique in treating this clinical challenge.Patient concerns:A 26-year-old man presented with severe trauma in the maxillofacial area due to fall from height.Diagnosis:Computed tomography images revealed middle face fractures and comminuted mandibular fracture including bilateral condyles.Interventions and outcomes:The computed tomography data was used to construct the 3D cranio-maxillofacial models; then the displaced bone fragments were virtually reduced. On the basis of the finalized model, a customized titanium mesh tray was designed and fabricated using selective laser melting technology. During the surgery, a submandibular approach was adopted to repair the mandibular fracture. The reduction and fixation were performed according to preoperative plan, the bone defects in the mental area were reconstructed with iliac bone graft. The 3D-printed mesh tray served as an intraoperative template and carrier of bone graft. The healing process was uneventful, and the patient was satisfied with the mandible contour.Lessons:Virtual surgical planning combined with 3D printing technology enables surgeon to visualize the reduction process preoperatively and guide intraoperative reduction, making the reduction less time consuming and more precise. 3D-printed titanium mesh tray can provide more satisfactory esthetic outcomes in treating complex comminuted mandibular fractures.

3D Printing and Digital Processing Techniques in Dentistry: A Review of Literature

et al. 2019

View full text Add to dashboard Cite

In recent years, the rapid development of 3D printing technologies lead to its new applications in the area of healthcare and medicine, including dentistry, orthopedics, cardiovascular, pharmaceutics, neurosurgery, engineered tissue models, medical devices, and anatomical models. Dentistry is widely acknowledged to benefit from 3D printing technologies due to its needs for the customization and personalization of dental products. In this review, the authors discuss and summarize various 3D imaging technologies and the recent advances of 3D digital processing techniques in dentistry in an effort to give a new perspective and greater understanding of the current development of 3D printing technologies in dentistry. It is anticipated that this review will explore why 3D printing is important to dentistry, and why dentistry motivates development in 3D printing applications. Further, current challenges and further perspectives are also discussed which helps researchers to optimize the 3D printing technology in dentistry, improve 3D printing strategies, and direct future dental bioprinting and translational applications.

Computer assisted mandibular reconstruction using a custom-made titan mesh tray and removable denture based on the top-down treatment technique

Abstract: We propose a computer assisted design for a custom-made Ti-mesh tray and a removable denture, based on the Top-down treatment concept. We feel this technique is advantageous in reconstructing functional occlusion, and in accurately regaining dental and facial esthetics.
