Advantages and disadvantages of 3-dimensional printing in surgery: A systematic review.

Rapid Prototyping Technologies and their Applications in Prosthodontics, a Review of Literature.

The complex three-dimensional anatomy of the craniofacial skeleton creates a formidable challenge for surgical reconstruction. Advances in computer-aided design and computer-aided manufacturing technology have created increasing applications for virtual surgical planning in craniofacial surgery, such as preoperative planning, fabrication of cutting guides, and stereolithographic models and fabrication of custom implants. In this review, the authors describe current and evolving uses of virtual surgical planning in craniofacial surgery.

Virtual surgical planning in craniofacial surgery.

An effort is made in this work to appraise the surface characteristics of machined expandable polystyrene (EPS) with a novel 3D printed thermoplastic acrylonitrile-butadiene-styrene (ABS) tool. Linear grooves on EPS were made on a vertical milling machine that was modified to conduct experiments in the laboratory. The tests were designed as per the Taguchi L9 based factorial design of experimentation while varying process parameters such as depth of cut, spindle speed, and feed rate. The machining responses dimensional accuracy and surface roughness of the machined grooves were studied. Furthermore, the surface topography of the machined specimens was considered to investigate the mechanism of material removal in response to the processing conditions. Moreover, mathematical models developed for the prediction of the output responses showed a significant correlation with the experimental results. The results of the statistical study indicate that the surface roughness is influenced by the spindle speed and dimensional accuracy by the depth-of-cut. Overall, the findings of the experimental work advocated the feasibility of 3D printed thermoplastic tools for machining soft polymeric materials. It can become a useful alternative for mass and batch production.

Surface Characteristics of Machined Polystyrene with 3D Printed Thermoplastic Tool

Summary Background Surgical correction of craniosynostosis aims to remodel the cranial vault to achieve a morphology approaching that of age-matched norms. However, current surgical technique is highly subjective and based largely on the surgeon's artistic vision in creating a normal head shape. Here, we present our technique and report our experience with the use of virtual surgery using computer-assisted design (CAD)/computer-assisted manufacturing (CAM) techniques to create a prefabricated template for the planning of osteotomies and the placement of bone segments, to achieve standardised, objective and precise correction of craniosynostosis. Methods Four patients who underwent cranial vault remodelling (CVR; three metopic synostosis and one sagittal synostosis) underwent virtual surgical planning (VSP) preoperatively using CAD/CAM techniques. VSP allows pre-planning of osteotomies to achieve the desired cranial vault shape. Surgical osteotomies and placement of bone segments were performed intra-operatively based on prefabricated templates. Results All patients demonstrated markedly improved head shape postoperatively. One patient developed a subdural haematoma 6 weeks postoperatively subsequent to a fall where he hit his head. The haematoma was drained and a soft spot was present in that location 3 months postoperatively. Conclusion The use of virtual surgery and prefabricated cutting guides allows for a more precise and rapid reconstruction. Surgical osteotomies are pre-planned and rapidly performed using a template, and precise placement of calvarial bone segments is achieved without the need for subjective assessment of the desired calvarial shape. In addition, patients and families have a significantly better understanding of the disease process and anticipated surgery preoperatively with the visualisation achieved through virtual surgery. This results in better alignment of hopes and expectations between the parents and surgeons.
