“…With this technique, preoperative preparation can easily be performed, resulting in accurate orbital reconstruction. In conventional orbital reconstruction, accurate reconstruction is created by constructing a model for custom-made preparation, such as a stereolithographic model, using 3D computer simulation data mirroring the uninjured side 15,11) . This can also be performed using computer-aided design / computeraided manufacturing along with the computer simulation data 30) .…”

The purpose of this study was to assess the level of accuracy that can be achieved in patients undergoing orbital reconstruction for orbital fl oor defect accompanied by midfacial fracture using an unsintered hydroxyapatite particles/ poly-L-lactide composite plate system with and without the use of intraoperative navigation. Eight consecutive patients treated using the u-HA/PLLA mesh plate system between 2014 and 2016 were included in this retrospective study. We analyzed the clinical and radiological data of these patients with orbital fl oor defect and midfacial fracture extending to the orbit. We examined the patients' postoperative healing status, including visual activity, diplopia, and enophthalmos. The overall volume of the orbit was calculated in cubic millimeters and was compared between the reconstructed orbit and the uninjured orbit for with and without the use of navigation groups. No patients complained of visual problems, and no further treatment was required postoperatively. Except for one patient with persistence of slight supraversion diplopia in the group without navigation, all the preoperative diplopia symptoms postoperatively improved, and none of the patients complained of problems in daily living. There was a signifi cant diff erence (p < 0.05) in the mean reconstructed orbital volume accuracy between with and without navigation. In conclusion, complex orbital reconstruction using optimal bioactive/resorbable material with intraoperative navigation is an accurate and reliable method of reconstruction.

“…Different fractures of maxillofacial structures can benefit from 3D printing but orbital wall fractures are the best targets for these methods [65][66][67]. These patients can be treated by 3D customized reconstruction of orbital wall defects with titanium mesh or sheet [68]. Before the surgery begins, titanium mesh or plate is adapted precisely on the 3D printed replica to help shortening the duration of general anesthesia [69,70].…”

Three-dimensional (3D) printing is cited as "a novel, fascinating, future builder technology" in many papers and articles. Use of this technology in the field of medicine and especially oral and maxillofacial surgery is expanding. The type of manufacturing systems, materials, cost-effectiveness, and also bio-printing, with studies from around the world today, make this field a "hot-topic" in reconstructive and regenerative surgery. This chapter evaluates the latest updates and scientific uses of 3D printing.

“…A customized medical implant and surgical resection template that matches skeletal anatomy can now be accurately designed using the CAD technique. The physical model of the individual implant, template, or skull replica can be produced through 3D printing, rapid tooling (RT), and computer aided manufacturing/computer numerical control (CAM/ CNC) processes [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. This paper presents some clinical cases, where virtual models have been used for surgical preparations and 3D printing models for manufacturing of implants.…”

In this paper, we report the benefit of Computer Tomography (CT), reverse engineering (RE) and rapid prototyping (RP) in individual implant production for maxillofacial surgery. The design and fabrication processes includes: a) processing medical image data of a patient's pathologically defective area having a symmetrical part to construct a three-dimensional (3D) digital model; b) forming an image on the defective side, in this step different techniques are applied for individual cases, including mirroring the non-defect side, implant design from other skull CT data; c) implant geometry modeling; d) 3D printing of the skull and implant model; e) surgical planning and prosthesis fitting; f ) casting of a custom-fit titanium implant. Results show that the CAD method can reconstruct the defect after surgical resection. The 3D printing technique provides an accurate tool for preoperative, surgical simulation. The design and manufacturing time of the bone implant has thus been significantly reduced using the CAD method.
