“…In this study, the null hypothesis and alternative hypothesis are investigated for statistical analysis [ 70 , 71 ]. The null hypothesis asserts that the median aesthetic score is less than or equal to 3 (H 0 : µ ≤ 3), whereas the alternative hypothesis asserts that it is larger than 3 (H a : µ > 3) [ 18 ]. Finally, the implant is validated using the FARO if the null hypothesis is rejected.…”

“…Three-dimensional printing has revolutionized the manufacturing business—particularly medical, aerospace, and automobile manufacturing, construction, and so on—with its groundbreaking material deposition technique [ 16 , 17 ]. The possibilities of 3D printing in the healthcare industry have substantially improved the ability to build components with complex geometries using medical imaging data, which would be unachievable through traditional approaches [ 18 ]. Furthermore, 3D printing reduces the patient’s surgery time and discomfort by avoiding surgery revisions.…”

The rehabilitation of the skull’s bones is a difficult process that poses a challenge to the surgical team. Due to the range of design methods and the availability of materials, the main concerns are the implant design and material selection. Mirror-image reconstruction is one of the widely used implant reconstruction techniques, but it is not a feasible option in asymmetrical regions. The ideal design approach and material should result in an implant outcome that is compact, easy to fit, resilient, and provides the perfect aesthetic and functional outcomes irrespective of the location. The design technique for the making of the personalized implant must be easy to use and independent of the defect’s position on the skull. As a result, this article proposes a hybrid system that incorporates computer tomography acquisition, an adaptive design (or modeling) scheme, computational analysis, and accuracy assessment. The newly developed hybrid approach aims to obtain ideal cranial implants that are unique to each patient and defect. Polyetheretherketone (PEEK) is chosen to fabricate the implant because it is a viable alternative to titanium implants for personalized implants, and because it is simpler to use, lighter, and sturdy enough to shield the brain. The aesthetic result or the fitting accuracy is adequate, with a maximum deviation of 0.59 mm in the outside direction. The results of the biomechanical analysis demonstrate that the maximum Von Mises stress (8.15 MPa), Von Mises strain (0.002), and deformation (0.18 mm) are all extremely low, and the factor of safety is reasonably high, highlighting the implant’s load resistance potential and safety under high loading. Moreover, the time it takes to develop an implant model for any cranial defect using the proposed modeling scheme is very fast, at around one hour. This study illustrates that the utilized 3D reconstruction method and PEEK material would minimize time-consuming alterations while also improving the implant’s fit, stability, and strength.

“…Such method shows accurate results compared to the human-based design for patient-specific cranial implants. Many studies have proposed a mirror image reconstruction technique for designing implant model 11,12,18,21 .

“…The study also informed that skull models can be reconstructed using a variety of commercial programs and libraries, for examples Open-Source Computer Vision (OpenCV), Open Graphic Library (OpenGL) OBJ Viewer and GLC Player. Mian Hammad S. et al 18 performed the mirror image reconstruction technique to create a personalized cranial implant. The left defective portion was replaced with the healthy right side of the skull model, preserving anatomical symmetry.…”

A specific design of craniofacial implant model is vital and urgent for traumatic head injury. A mirror technique is conventionally employed for modelling. However, such method requires healthy skull region identically opposite to a defect. We therefore propose the three processing workflows for modelling implants: mirror, baffle planner and baffle-based mirror guideline. The workflows are based on implementing extension modules on the 3D Slicer platform. We investigated the craniofacial CT datasets collected from the four accidental cases. The designed implant models were created from conducting the three workflows and compared to the reference models created by the experienced neurosurgeon. The spatial properties-based performance metrics were evaluated. The results show that the mirror method suits craniofacial cases whereby healthy skull region can be completely reflected to the defect region. The baffle planner module offers a flexible prototype model fit independently to any defect location. However, the baffle planner method requires customized refinement of contour and thickness to fill the missing region seamlessly. The process also relies on a user’s experience and expertise. The proposed baffle-based mirror guideline method strengthens the baffle planner method by tracing the mirrored surface. Such three proposed workflows simplify craniofacial implant modelling and can practically be employed for a variety of craniofacial scenarios.
