“…In addition to reducing surgical time, digital software allows mirroring of contralateral structures or personalized reconstructions in a virtual environment. The object created for reconstruction can be made (printed or milled) in the grafting material or a negative impression can be used as a template for using the PMMA (Da Silva et al, 2017;Đurić et al, 2019). Inclusion of technologies for planning and making facial skull reconstructions, as observed in the present case, is a reality and should, in the authors' view, be encouraged to optimize clinical results.…”

Anophthalmia is mainly caused by two etiological groups, trauma and medical conditions. In addition, anophthalmia creates difficulties in social, professional, and family adaptation due to psychological, and functional disorders related to eye loss. Studies show a positive influence on the personal relationship of patients with anophthalmia after being rehabilitated with ocular prostheses. However, in order to achieve a good aesthetic result in prosthetic eye rehabilitation, it is essential that the size and positioning of the orbital skeleton are adequate. Facial trauma can also cause defects associated with bone loss, and in these cases, reconstructive techniques aim to restore the appropriate bone contour. The aim of this work is to report a case where reconstructive treatment was performed on a patient victim of a long-term traffic accident sequel, using an alloplastic implant in polymethylmethacrylate (PMMA) and bone repositioning, so that an ocular prosthesis could be made. At the end of the treatment, after reconstruction of the frontal-nasal region in PMMA and repositioning of the left zygoma, the aesthetic objectives were achieved and the patient improved his self-esteem and social life.

“…With the current paradigms of personalised medicine, various methods have come about to improve the aesthetic results of cranioplasties [7][8][9][11][12][13][14][15][16][17][18]. This revolution in modern practice occurs due to the 3D printing of biomaterials and its disruptive applications in the twenty-first century medicine.…”

“…The use of 3D images facilitated the integration between medical staff and engineering. As observed in several articles [6,[9][10][11][12][13][14][15][16][17][18], the various CAD/CAM techniques offer safe and satisfactory aesthetic results regardless of the implanted biomaterial, provided that an appropriate scientific methodology is followed. In our experience, the ideal algorithm for mould production was observed when the surgeon adequately expressed his/her need to the engineering team via a medical phantom.…”

“…In the last two decades [8,[11][12][13], custom implant production based on 3D computed tomography (CT) with computer-aided design/computer-aided manufacturing (CAD/CAM) has been constantly refined, aiming for a precise and aesthetic fit over the cranial defect. The ideal implant biomaterial continues to be extensively researched, and several options have been used with similar results [14][15][16][17].…”

Cranioplasty with three-dimensional customised mould for polymethylmethacrylate implant: a series of 16 consecutive patients with cost-effectiveness consideration

et al. 2021

Background Different methods of cranioplasty for the reconstruction of bony skull defects exist. In the absence of the autologous bone flap, a customised manufactured implant may be the optimal choice, but this implant has several limitations regarding its technical standardisation and better cost-effectiveness. Methods This study presents a series of 16 consecutive patients who had undergone cranioplasty with customised three-dimensional (3D) template moulds for polymethylmethacrylate (PMMA) implants manufactured after 3D modelling on a specific workstation. The virtual images were transformed into a two-piece physical model using a 3D printer for the biomaterials. PMMA implant was produced intraoperatively with the custom mould. Cosmetic results were analysed by comparing pre- and postoperative 3D computed tomography (CT) images and asking if the patient was satisfied with the result. Results The average total time for planning and production of customised mould was 10 days. The 16 patients were satisfied with the result, and CT images presented harmonious symmetry when comparing pre- and postoperative scans. Cases of postoperative infection, bleeding, or reoperation in this series were not observed. Conclusion Cranioplasty with high-technology customised 3D moulds for PMMA implants can allow for an aesthetic reconstruction with a fast and cost-effective manufacturing process and possibly with low complication rates.
