Summary: This study evaluated the primary fixation stability of CAD/CAM fixators and compared the performance of different types of fixators under biomechanical conditions. The results showed that CAD/CAM miniplates had higher mechanical strains, while CAD/CAM reconstruction plates resulted in higher strains. However, the stresses in the fixation systems were below the material yield stress, indicating that material failure would not be expected.

Summary: This paper provides a comprehensive summary of the clinical applications of computer-aided design/computer-aided manufacturing (CAD/CAM) in maxillofacial surgery, and reviews the experience using an in-house rapid prototyping technique. The study focused on reconstructive surgery, traumatology, and COVID-19 masks, showing that the low cost and efficiency make this method applicable to a large number of cases for both ordinary and extraordinary activities.

Summary: This study aims to assess the impact of patient-specific implants (PSI) versus conventional osteosynthesis (non-PSI) on osseous union following fibula-free flap (FFF) jaw reconstruction and identify risk factors for incomplete osseous union. The study found that the rate of incomplete bony fusion was significantly higher in the PSI group. The type of osteosynthesis and adjuvant radiotherapy were identified as independent risk factors for incomplete osseous union.

Summary: The study focused on testing experimental rapid prototyping materials for occlusal splints made from Urethandimethacrylate (UDMA) and Urethanmethacrylate (UMA). Mechanical properties were significantly influenced by changes in the UDMA:UMA ratio, with increased amounts of UMA correlating with a decrease in flexural strength, modulus of elasticity, hardness, and wear resistance. Optic properties showed minor influence from UMA content and aging, while gloss was partly influenced by the UDMA:UMA ratio and water storage. Mean survival rates for cyclic pull-off and insertion testing ranged from 2537 to 23,857 cycles, with a correlation observed between the amount of UMA and survival rates. The addition of up to 25% UMA showed promising results, complying with clinical standards and delivering acceptable results in the cyclic pull-off and insertion test.

Summary: This study compared the application of auxiliary techniques in mandibular reconstruction. The use of adjustable resection/reconstruction aids and CAD/CAM assistance showed no significant differences in terms of feasibility, accuracy, and operative parameters. However, the adjustable aids had advantages of less preoperative planning time and lower costs per case, which may be more favorable for mandibular angle-to-angle reconstruction.

Summary: Computer-aided microvascular mandible reconstruction with patient-specific reconstruction plates is a common procedure in oral and maxillofacial surgery. This study evaluated the rate and reasons for hardware removal after fibula free flap fixation. The results showed that hardware removal was frequently performed for dental implantation and the majority of cases underwent intraoral removal. Intraoral removal was associated with shorter hospitalization and the use of patient-specific miniplates facilitated dental rehabilitation.

Summary: The aim of this study was to compare the outcomes of condylar reconstruction using fibula free flap (FFF) with conventional freehand and CAD/CAM techniques. Fifteen patients who underwent FFF condylar reconstruction were evaluated using pre- and postoperative imaging scans and clinical function assessment. The results showed that both freehand and CAD/CAM techniques had similar outcomes in terms of pain reduction and mouth opening, but there was a deviation of the jaw movement to the side of surgery. The CAD/CAM technique facilitated surgery and improved the fit of the neocondyle in the fossa.

Summary: The use of deep learning in medical imaging is expanding, and in this study, a U-Net model was used for automatic segmentation of facial bones. The results showed high accuracy, particularly for the mandible and zygomatic bones, while other areas, like the teeth, had slightly inferior results. Further research is needed to improve accuracy in these areas and validate the results in larger and more diverse populations.

Summary: This study aimed to compare the advantages and disadvantages of a virtual reality (VR) environment and a computer desktop screen (DS) environment for virtual surgical planning (VSP). The results showed that the VR environment had a steeper learning curve and shorter time requirements, but there was no difference in the quality of the models compared to the DS environment. Participants generally found the VR environment to be more intuitive and less exhausting, and preferred it over the DS environment.

Summary: Comparing the reference geometry approach with the best-fit approach for estimating geometric accuracy in the digital and analog workflow of fabricating complete dentures. The study tested both methods to estimate the accuracy of the intaglio surface of dentures made by CNC milling and injection molding. The results showed that the reference geometry approach correctly estimated error values and identified sources of errors, while the best-fit approach underestimated the mean error values and their distribution over the entire prosthesis.

Summary: Virtual reality (VR) surgery using the HTC VIVE Pro2 suite provides a multi-sensory and holistic surgical training experience. Trainees can interact with the components of cranialmaxillofacial (CMF) anatomy and use surgical instruments while watching close-up stereoscopic three-dimensional videos. A novel immersive virtual reality (iVR) training tool for pre-hospital treatment of CMF trauma was developed and evaluated by 25 CMF surgeons. The results confirmed the applicability of VR for CMF trauma rescue simulation training.
