Cranioplasty is the procedure that is frequently used to treat deficiencies in the skull bone brought on by skull abnormalities in bone, traumatic skull fractures, bone malignancy, and infections. In surgery, biocompatible materials with unique properties have been utilized. Given the functionality and aesthetic standpoint, the human skull approach for repairing and restoring the abnormalities is hugely challenging. Polymethylmethacrylate (PMMA) cement, based on a dough-like material formed by combining two powdered polymer and liquid monomer components, is considered one of the earliest materials to treat cranial defects. Regarding the development of the latest additive manufacturing technologies, 3D printing has become a promising method for creating cranial implants customized to each patient. This study uses a solid basic medical grade PMMA material as a basis filament for the fused filament fabrication (FFF) process. This paper presents a high-quality model and manufacturing of a left parietal-temporal implant in the human skull based on computed tomography CT images. It evaluates the fitting accuracy and topographical roughness of the PMMA cranial implant. The results proved that the root means square error values for the deviation between the cranial implant’s physical model and its planned model are (0.628, 0.833, and 0.650 mm) and implant roughness measurements are (2.5, 2.81, and 3.23 μm). The implemented framework outlined in the present study indicates that the contour continuity between implant-skull overlap, fitting accuracy, implant roughness topography, and the cosmetic outcome achieved entirely satisfactory results.
Reconstructed the skull defect by using mouldless 3D printing PMMA to manufacture high-quality patient-specific cranial implants directly.
A qualitative and quantitative evaluation of implant dimensional accuracy is given and ensure the contour continuity between implant-skull overlap is ensured.
Evaluate the cranial implant surface topography.
