“…In recent years, 3D printing has had medical applications in different areas like specialized planning through the simulation of the entire surgical sequence, using model prototypes, which gives a better appreciation of different anatomical details. This may result in a reduction in operating time and in an improvement of the use of resources in operating rooms (D'Urso et al, 1999;Wagner et al, 2004;Gerstle et al, 2014). On the other hand, 3D printouts are useful for educating the patient, or during the pre-or post-operative stage (Gerstle et al).…”

ARANEDA, N.; PARRA, M.; OSORIO, J. V. & OLATE, S. 3D Print of the maxillary sinus for morphological study. Int. J. Morphol., 35(3):1102Morphol., 35(3): -1106Morphol., 35(3): , 2017. SUMMARY:The maxillary sinus (MS) is described as a pyramid-shaped cavity of the maxilla. Knowledge of its morphology makes it possible to define normality and abnormality so that its three-dimensional analysis can be a valuable preoperative tool during surgery in this anatomical area. The aim of this study is to present a strategy of morphological analysis of the MS using 3D printing acquired through computed cone beam tomography (CBCT) images. A cross-sectional descriptive study was conducted, including 15 subjects (8 women and 7 men). The 3D virtual reconstruction and modeling was done on the MSs bilaterally, and 30 physical models were produced on a 3D printer. The results revealed that the MSs obtained exhibited various morphologies. An individual analysis of each MS allowed the tripod nature of the MS to be defined. We also were able to observe anatomical repairs such as the MS ostium, as well as complex areas affecting important surgical decisions. This method for creating 3D models of MSs provides a new approach to understanding the precise anatomical characteristics in these structures, which cannot be assessed in the same way on a 2D screen. It may be concluded that 3D printouts of the MS are a suitable method of preoperative analysis that can be useful in educating the patient, however, less time-consuming strategies should be explored.

“…A universal mandibular reconstruction plate (Stryker Leibinger 4100 E. Milham Ave. Kalamazoo MI 49001) was then accurately and precisely bent to fit the contours of the 5 cm defect preoperatively [12] [ Figure 2]. In addition, screw length measurements were also determined in millimeters with the aid of a Boley gauge (Keystone, Orthozone.com) and recorded.…”

The reconstruction of boney defects of the mandible are a challenge in surgical therapy despite advances in bone grafting. This case study details a 30-year-old female who sustained a gunshot wound to the mandible leaving a 5 cm boney defect. This defect was reconstructed utilizing preoperative three-dimensional (3D) planning, an accurately pre-bent reconstruction plate, and a novel "triad" construct of autogenous bone graft, demineralized bone matrix, and an osteoprotective membrane. This reconstruction workflow allowed maintenance of the contour of the mandible and bone regeneration while also acting as a barrier to other tissues. This new technique reduced operative donor site morbidity and decreased surgical time dramatically, allowing the patient to be discharged the same day. The patient has a 5-year follow-up with panorex film and a biopsy of the graft area showing normal cortical bone. This case report illustrates the combination of advanced technology and novel products which can decrease operating time, decrease anesthesia time, increase precision, and most importantly decrease patient morbidity.

“…When plates contoured on 3D models before surgery are used, they bring the segments into alignment when they are fixed to the bone with screws. Therefore, the contoured plates not only serve to reconstruct the fracture but also act as templates to establish the final phase of alignment with precision (Wagner et al, 2004). A 3DP model has also been used for repairing orbital floor fractures using pre-shaped titanium mesh implants formed based on anatomical 3DP models of the orbit (Kozakiewicz et al, 2009).…”
