“…Time-efficiency was reported in four studies with print durations ranging up to to 36 hours,16 and two studies highlighted the potential for delivering custom 3D-printed devices to patients within 24 hours 17 18. Cost-effectiveness of 3DP was emphasised in two cases (US$30 for a head mould to replace a US$200–US$400 CT scan16 and a US$5 custom-fit BiPAP mask16), and one study considered the price disadvantageous (US$500 for materials and printing of an obturator definitive cast) 19…”

BackgroundThree-dimensional printing (3DP) enables the production of highly customised, cost-efficient devices in a relatively short time, which can be particularly valuable to clinicians treating patients with palliative care intent who are in need of timely and effective solutions in the management of their patients’ specific needs, including the relief of distressing symptoms.MethodFour online databases were searched for articles published by December 2020 that described studies using 3DP in palliative care. The fields of application, and the relevant clinical and technological data were extracted and analysed.ResultsThirty studies were reviewed, describing 36 medical devices, including anatomical models, endoluminal stents, navigation guides, obturators, epitheses, endoprostheses and others. Two-thirds of the studies were published after the year 2017. The main reason for using 3DP was the difficulty of producing customised devices with traditional methods. Eleven papers described proof-of-concept studies that did not involve human testing. For those devices that were tested on patients, favourable clinical outcomes were reported in general, and treatment with the use of 3DP was deemed superior to conventional clinical approaches. The most commonly employed 3DP technologies were fused filament fabrication with acrylonitrile butadiene styrene and stereolithography or material jetting with various types of photopolymer resin.ConclusionRecently, there has been a considerable increase in the application of 3DP to produce medical devices and bespoke solutions in the delivery of treatments with palliative care intent. 3DP was found successful in overcoming difficulties with conventional approaches and in treating medical conditions requiring highly customised solutions.

“…The data available from the existing literature revealed the following acquisition modalities: CT scans [26,29,31,36,39,41,43,46,54,60,67,71], MRIs, CBCTs (for maxillary obturators) [22,24], structured light scanners [19][20][21]23,58], laser scanners [37,49,51,56,57,[62][63][64]68,70], light intensity scanners [30], facial scanners, intraoral scanners (IOSs) [3,18,25,27,32,44,53], desktop scanners [34,66], 3D photogrammetry [28,40,52,55,59,69], the monoscopic photogrammetry technique with a mobile phone [15] or two (or more) of the following combined registration modalities: CT and a facial scanner [61], CT an...…”

“…Medical scanning (CT, MRI and CBCT) was used in many reported cases [22,24,26,29,31,36,39,41,43,46,50,54,60,67,71] for defect data acquisition. The choice of image data is extremely important, with low-resolution images resulting in discrepancies from the actual anatomy, and a high resolution requires greater radiation exposure in the case of CT and CBCT scans [13].…”

“…This is a very useful tool for retaining or removing areas of interest, corresponding to the density values of tissue types [84], and due to recent advances in segmentation software, it can be done automatically or semiautomatically [85]. Commercially available software was preferred, with Mimics (Materialise, Belgium) being used in most of the published reports [22,31,42,43,46,54,60]. The open-source software 3D Slicer (The Slicer Community) and Slic3r were each used in one case.…”

Digital Workflow in Maxillofacial Prosthodontics—An Update on Defect Data Acquisition, Editing and Design Using Open-Source and Commercial Available Software

et al. 2021

View full text Add to dashboard Cite

Background: A maxillofacial prosthesis, an alternative to surgery for the rehabilitation of patients with facial disabilities (congenital or acquired due to malignant disease or trauma), are meant to replace parts of the face or missing areas of bone and soft tissue and restore oral functions such as swallowing, speech and chewing, with the main goal being to improve the quality of life of the patients. The conventional procedures for maxillofacial prosthesis manufacturing involve several complex steps, are very traumatic for the patient and rely on the skills of the maxillofacial team. Computer-aided design and computer-aided manufacturing have opened a new approach to the fabrication of maxillofacial prostheses. Our review aimed to perform an update on the digital design of a maxillofacial prosthesis, emphasizing the available methods of data acquisition for the extraoral, intraoral and complex defects in the maxillofacial region and assessing the software used for data processing and part design. Methods: A search in the PubMed and Scopus databases was done using the predefined MeSH terms. Results: Partially and complete digital workflows were successfully applied for extraoral and intraoral prosthesis manufacturing. Conclusions: To date, the software and interface used to process and design maxillofacial prostheses are expensive, not typical for this purpose and accessible only to very skilled dental professionals or to computer-aided design (CAD) engineers. As the demand for a digital approach to maxillofacial rehabilitation increases, more support from the software designer or manufacturer will be necessary to create user-friendly and accessible modules similar to those used in dental laboratories.
