“…This systematic review showed that whereas reconstruction after benign lesion resection, reconstruction between 8 and 12 years of age (which was termed the rapid growth stage), and condylar preservation facilitate postoperative mandibular growth, postoperative radiotherapy inhibits the same. 49 In our experience, most free flaps continue to grow with the recipient area, and there is no marked evidence that surgery influences donor site growth. We had some cases with continuous radiographs during follow-up that demonstrate growth of transferred fibula (Fig.…”

“…We reviewed a series of 51 patients < 18 years of age who underwent mandibular reconstruction with vascularized fibula flaps from 15 articles; we found that the number of patients with preserved growth potential was greater than those with no growth potential and concluded that the growth potential of the fibula was related to age, condylar preservation, tumor pathology, and postoperative radiotherapy. This systematic review showed that whereas reconstruction after benign lesion resection, reconstruction between 8 and 12 years of age (which was termed the rapid growth stage), and condylar preservation facilitate postoperative mandibular growth, postoperative radiotherapy inhibits the same …”

“…With help the guide plate, the implants are positioned exactly where planned virtually. The reconstructed mandible must be properly aligned with the maxilla in both the horizontal and vertical planes, with adequate intermaxillary space to insert a prosthesis ( 25 , 26 ). Therefore, we recommend the position of implant should be considered in the virtual plan before the mandibular reconstruction, whether taking the dental implant in the first-stage or second-stage.…”

BackgroundThis study was to evaluate the use of virtual planning and 3D printing modeling in mandibular reconstruction and compare the operation time and surgical outcome of this technique with conventional method.Material and MethodsBetween 2014 and 2017, 15 patients underwent vascularized fibula flap mandibular reconstruction using virtual planning and 3D printing modeling. Titanium plates were pre-bent using the models and cutting guides were used for osteotomies. 15 patients who underwent mandibular reconstruction using fibula flap without aid of virtual planning and 3D printing models were selected as control group. The operation time was recorded and compared in two groups. Accuracy of reconstruction was measured by superimposing the preoperative image onto the postoperative image of mandible. The selected bony landmark, distance and angle were measured.ResultsThe mean total operation time and reconstruction time were 1.60±0.37 and 5.54±0.50 hours in computer-assisted group, respectively; These were 2.58±0.45 and 6.54±0.70 hours in conventional group, respectively. Both operation time and reconstruction time were shorter in computer-assisted group. The difference between the preoperative and postoperative intercondylar distances, intergonial angle distances, anteroposterior distances and gonial angles were 2.92±1.15 and 4.48±1.41mm, 2.93±1.19 and 4.79±1.48mm, 4.31±1.24 and 5.61±1.41mm, 3.85±1.68° and 5.88±2.12° in the computer-assisted and conventional group, respectively. The differences between the preoperative and postoperative mandible is smaller in the computer-assisted group.ConclusionsVirtual planning and 3D printing modeling have the potential to increase mandibular reconstruction accuracy and reduce operation time. we believe that this technology for mandibular reconstruction in selected patients will become a used method and improve the quality of reconstruction. Key words:Mandibular reconstruction, fibula flap, virtual planning, computer-assisted design, 3D printing.

“…In dogs, reported techniques include free cortical ulnar and rib autografts with autogenous cancellous bone graft following segmental mandibulectomy, 2,3 rib allograft with recombinant human bone morphogenetic protein 2 following segmental mandibulectomy, 4 and absorbable compression resistant matrix (containing collagen, hydroxyapatite, and tricalcium phosphate soaked in recombinant human bone morphogenetic protein 2) following segmental mandibulectomy 5,6 and bilateral rostral mandibulectomy. 7 Common techniques used in humans for reconstruction of segmental mandibular defects include vascularized free osteocutaneous grafts, [8][9][10] particularly fibular osteocutaneous grafts, and distraction osteogenesis. 11 The increase in the availability of CT planning has resulted in advances in the management of mandibular defects in humans, including creation of 3-D models of the affected mandible for surgical planning (such as prebending and improved fitting of titanium plates, optimization of bone-to-bone contact, and shorter duration of surgery), 9,[12][13][14][15][16][17][18][19] creation of prefabricated intraoperative guides (for optimization of the length and number of fibular grafts, improved fitting of titanium plates, and improved postoperative cosmetic appearance and function), 9,16,[19][20][21] and development of CAD-CAM customized and patientspecific 3-D-printed reconstruction plates 9,22 and prostheses.…”

CASE DESCRIPTION A 12-year-old neutered male domestic shorthair cat had been treated for a mass arising from the lingual aspect of the caudal right mandibular body. Cytoreductive surgery of the mass had been performed twice over a 2-year period, but the mass recurred following both surgeries. The mass was diagnosed as an osteosarcoma, and the cat was referred for further evaluation and treatment. CLINICAL FINDINGS Clinical findings were unremarkable, except for a 2-cm-diameter mass arising from the lingual aspect of the right mandible and mild anemia and lymphopenia. Pre- and postcontrast CT scans of the head, neck, and thorax were performed, revealing that the osteosarcoma was confined to the caudal right mandibular body, with no evidence of lymph node or pulmonary metastasis. TREATMENT AND OUTCOME The stereolithographic files of the CT scan of the head were sent for computer-aided design and manufacture of a customized 3-D-printed titanium prosthesis. Segmental mandibulectomy was performed, and the mandibular defect was reconstructed in a single stage with the 3-D-printed titanium prosthesis. The cat had 1 minor postoperative complication but had no signs of eating difficulties at any point after surgery. The cat was alive and disease free 14 months postoperatively. CLINICAL RELEVANCE Reconstruction of the mandible of a cat following mandibulectomy was possible with computer-aided design and manufacture of a customized 3-D-printed titanium prosthesis. Cats have a high rate of complications following mandibulectomy, and these initial findings suggested that mandibular reconstruction may reduce the risk of these complications and result in a better functional outcome.
