“…For converting the DICOM data obtained from medical scanning (e.g., CBCT) and generating a surface mesh (Stereolithography file format -STL), an image editing program is used, with a threshold tool allowing a range of values to be set from the data to be retained while ignoring data that falls outside the range [13,83]. 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].…”

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.

“…Hee‐Jin Kim et al. performed total excision of the left maxilla under the guidance of augmented reality by pasting the image target on the patient's forehead to remove malignant fibrous histiblastoma 15 . The advantage is that there are fewer incision and dissection, but the camera is fixed in position and cannot match the operator's field of view perfectly.…”

Background: Recognition of markers in the augmented reality system can reduce the additional cost of a guide plate required for the removal of benign tumours in oral and maxillofacial surgery, but the use of markers often has complex problems. Method:In order to avoid the complex problem of using markers, an augmented reality system based on a marker-free registration method was proposed to track the contour of the mandible edge. Use the computer to perform preoperative planning on the jaw model, select and mark the path of maxillofacial lesion resection.Results: This method has an error of the surface matching was 0:6453 � 0:2826 mm, and an error of the surgical resection was 0:4858 � 0:3712 mm. Conclusions:We demonstrate that the system can accurately enhance the display of the surgical path and provide guidance for the tradition of maxillofacial surgery.

“…A literature review shows that the effectiveness of VR has been helpful in increasing surgery success rates [ 31 , 32 ] and improving police safety when on duty [ 33 ], and it has effectively been used in earthquake safety training [ 34 ], fire extinguisher training [ 13 ], fire and rescue training [ 35 , 36 ], and in increasing adherence to meditation practices [ 37 ]. Most academic research on simulations involves the use of head mounted displays (HMD), and the sound comes from headphones on both sides.…”

In Taiwan, firefighters are responsible for transporting confirmed coronavirus cases to hospitals or epidemic prevention hotels. During the epidemic, in order to reduce the chance of cross-infection between the general public and the fire brigade, traditional collective mobilization training was limited. As a solution, this study combines a fire command course (C1) and a VR simulation for training fire station captains (VRST) and then applies the pre- and post-test evaluation approaches and the after-class questionnaire to summarize the learning effectiveness. The results show that, from a total of 244 captains that were trained, the after-training scores are significantly better when compared with the scores before training (p < 0.05, Cohen’s d > 0.8). Additionally, the post-test scores collected during the epidemic (n = 158) have no significant difference compared to the ones taken before the outbreak (2019, n = 86) in terms of sizing up, decision making, and safety management. The training results are still improving. The after-class questionnaire showed that most trainees believed that VRST helped to improve their confidence as incident commanders (ICs) (mean = 4.63, top box = 66.98%), with the novice and suburban groups exhibiting more significant improvements in command ability after the training. After the pandemic, VRST can continue as a regular training method for IC-01s. Because of the intervention of VRST, the differences in the command experience between different IC groups can be compensated for.
