“…The fidelity of 3D printing has always been a fundamental target for researchers to achieve [ 37 , 38 ]. The free radical polymerization in a liquid material during an over-exposure time may lead to an exceeding of size over the designed one, while an insufficient exposure cannot guarantee shaping.…”

The malalignment of teeth is treated classically by metal braces with alloy wires, which has an unfavorable influence on the patients’ appearance during the treatment. Herein, a modern treatment was tried using clear polymeric aligners, which were fabricated by molding a film material on the three dimensional (3D) printed personalized dental models. The key parameters of photocurable 3D printing of dental models and the mechanical properties of the clear aligner film material were investigated. Following a series of 3D-printed personalized dental models and finite element analysis to predict and plan the fabrication and orthodontic processes, clear aligners were fabricated and applied in animal experiments to prove the efficacy and biocompatibility. A clinical treatment was finally carried out, which highlights the advantage of the clear aligners as an esthetic, compatible and efficient appliance.

IntroductionComplex ectopic drainage of body veins is a rare congenital disease. Its preoperative diagnosis and surgical choice can be considerable challenges.Case SummaryA 5-year-old patient was diagnosed precisely by preoperative transthoracic echocardiography, computed tomography (CT), three-dimensional (3D) reconstruction, and three-dimensional (3D) printing of the heart and great blood vessels. The operation was performed successfully using flexible intraoperative intubation strategies.Conclusion3D printing technology can assist in the formulation of surgical protocols for complex body vein ectopic drainage. Flexible intubation strategies can increase the success of the operation.

“…In order to overcome this possible problem, new technologies have emerged, where the virtual 3D model is projected the virtual and/or mixed reality space [38,39] and the spectator wearing special glasses can interact with them with/out haptic feedback [40][41][42] (Figure 1B). These developing techniques are in the process of maturation and in finding their niche in the clinical armamentarium [43][44][45][46]; however, the need for 3D-printed models remains, as they readily exist in the physical reality and they accurately demonstrate rather complex morphologies [47], which can be printed with the physical properties of native tissues [48].…”

Three-Dimensional Virtual and Printed Prototypes in Complex Congenital and Pediatric Cardiac Surgery—A Multidisciplinary Team-Learning Experience

Three-dimensional (3D) virtual modeling and printing advances individualized medicine and surgery. In congenital cardiac surgery, 3D virtual models and printed prototypes offer advantages of better understanding of complex anatomy, hands-on preoperative surgical planning and emulation, and improved communication within the multidisciplinary team and to patients. We report our single center team-learning experience about the realization and validation of possible clinical benefits of 3D-printed models in surgical planning of complex congenital cardiac surgery. CT-angiography raw data were segmented into 3D-virtual models of the heart-great vessels. Prototypes were 3D-printed as rigid “blood-volume” and flexible “hollow”. The accuracy of the models was evaluated intraoperatively. Production steps were realized in the framework of a clinical/research partnership. We produced 3D prototypes of the heart-great vessels for 15 case scenarios (nine males, median age: 11 months) undergoing complex intracardiac repairs. Parity between 3D models and intraoperative structures was within 1 mm range. Models refined diagnostics in 13/15, provided new anatomic information in 9/15. As a team-learning experience, all complex staged redo-operations (13/15; Aristotle-score mean: 10.64 ± 1.95) were rehearsed on the 3D models preoperatively. 3D-printed prototypes significantly contributed to an improved/alternative operative plan on the surgical approach, modification of intracardiac repair in 13/15. No operative morbidity/mortality occurred. Our clinical/research partnership provided coverage for the extra time/labor and material/machinery not financed by insurance. 3D-printed models provided a team-learning experience and contributed to the safety of complex congenital cardiac surgeries. A clinical/research partnership may open avenues for bioprinting of patient-specific implants.
