3D printed Bone Models for Planning and Training in Oral and Cranio maxillofacial Surgery a Systematic Review Book PDF/Epub Download
Background:In the past decades additive manufacturing has strongly changed the medical field. The possibility of creating accurate three-dimensional (3D) printed patient-specific models is one of the most interesting prospects. These models, created with multiple materials and techniques, are used for simulating, training and planning surgeries, giving a better comprehension of patientu2019s condition and allowing more realistic hands-on training and case discussions. Objective: The aim of this review is defining the state of the art of 3D-printed bone models in oral and cranio-maxillofacial surgery. The main question was: u2018What are the existing printed bone models currently used for training, planning and simulating interventions in oral and cranio-maxillofacial surgery?u2019Methods:PubMedu00ae and SCOPUSu00ae databases were searched by following the Preferred reporting items for systematic reviews and meta analyses (PRISMA). Grey literature and hand search were also included. Study selection, quality assessment (modified Critical Appraisal Skills Program tool) and data extraction were performed by two independent reviewers.All original full papers in English/French/Italian dealing with the fabrication of 3D printed models of head bone structures obtained from 3D imaging data were included in this research.Multiple data were extracted: data acquisition system, type of printing technique, printing material, accuracy, haptic feedback, variations in treatment time, differences in clinical outcomes, costs, production time and cost-effectiveness. A narrative synthesis of the data was conducted due to the heterogeneity of study designs and methods.Results:Starting from 774 abstracts, the authors have included 54 articles. 3D printed models were mostly used in oral and maxillo-facial surgery for planning and training bone reconstruction and tumor removal. The most used image processing software are Mimicsu00ae(Materialize) and OsiriXu00ae(Pixmeo, open-source). The cheapest, fastest and most described printing technique is the fused deposit modeling (FDM) one. Among all the FDM printing materials, polycarbonate showed the most human-like properties. The best accuracy and haptic feedback were obtained with material jetting (MJ) and stereolithography (SL) printers. Multiple authors described a reduction of surgical time up to 20% after doing surgical simulations. Titanium mesh made on 3D printed models permitted to have greater outcomes in terms of esthetic and functional results, compared to mesh modeled during the surgery. Several authors declared that the quality of training increased using 3D printed models, after evaluating the studentsu2019 satisfaction.Conclusion:3D printed models demonstrated to be useful surgical and academical tools. Due to the large amount of different software, printers and materials, clinicians and researchers has to choose carefully their own printing work-flow. MJ and SL are the best technique to create respectively simulating and planning models. FDM permit to create adequate training models, despite their limited accuracy. The lack of common qualitative and quantitative test is an evident limitation of this study.
