“…In one study, comparison was done in two patients for prosthesis construction directly on skull and printed directly using 3D technology. None of case reports/series reported any complications after the surgery and reported satisfactory/ improved/good/excellent aesthesis [29][30][31][32][33][34][35][36] (►Table 1).…”

Background Health Technology Assessment in India assesses, evaluates, and carries out cost-effectiveness of available health technologies in the country for evidence-based decision-making. Current study carried out a scoping review to assess clinical efficacy of poly-methyl-methacrylate (PMMA) after decompressive craniectomy using various prototyping techniques in published literature. Methods The O'Malley methodology and Preferred Reporting Items for Systematic Reviews and Metanalysis for Scoping Reviews—PRISMA-ScR—checklist were used to assess published literature from year 2008 to 2023. Results A total of 507 records were identified after searching electronic databases. After removing duplicate studies and studies that did not meet inclusion criteria, a total of 12 studies were included for review. A total of four studies were described as experimental and eight were case reports/series. The sample size of intervention studies varied between 10 and 30 patients with a mean age of 36.7 years. In a total of seven studies, cranioplasty was done by a self-made PMMA prosthesis fabricated using a novel three-dimensional-printed cranial model fabrication technique. In experimental study, objective criteria like operative Glasgow Outcome Scale, Cranial Index of Symmetry score, and Visual Analog Score for Cosmesis were employed. Conclusion Clinical assessment for cranial symmetry was observed favorable for PMMA with fewer complications, though sample size was inadequate (range: 10–30) with comparator group in two studies.

“…The 3D-printed PMMA or titanium prostheses were reported to have favorable outcomes. PMMA acrylic prostheses are more susceptible to infection [ 12 ] and tissue necrosis, which not only necessitates prostheses removal [ 13 ] but also jeopardizes the soft tissue over the defect, making further reconstructions more challenging [ 4 ]. Jaberi et al reconstructed 70 patients with PMMA custom-made implants and reported a 24% complication rate [ 14 ].…”

“…Whether prefabricated or custom-made, alloplastic materials are mainly made from titanium or polymathic methacrylate (PMMA) [ 3 ]. PMMA is economically affordable [ 3 , 4 ]; however, it is not as strong as titanium [ 5 ]. Moreover, PMMA prostheses are more prone to infection, local irritation, foreign body reaction, and thermal damage during polymerization in the case being used as a cement for prosthesis adaptation.…”

Management of patients with congenital skull defects requires a multidisciplinary approach. Considering the defect’s location and size, brain protection, and the cosmetic outcome makes such reconstructions challenging. Due to limited resemblance to skull contour and donor site morbidity of autogenous bone grafts, alloplastic materials are widely used for skull reconstructions. Titanium alloys have proper strength values, low infection rates, favorable osseointegration property, and excellent marginal adaptability when manufactured by computer-aided design (CAD) and computer-aided manufacturing (CAM). A 13-year-old female patient presented with congenital defects at the superior third of occipital bone and posterior thirds of the bilateral parietal bones. On CT scan, the exact size and shape of the defect were determined. Using CAD/CAM, a 3D virtual model of the prosthesis was designed and then printed with titanium alloy (TiAl6V4) via additive manufacturing method. The prosthesis was placed on the defect in a total surgery time of only 90 minutes. On 4.5 years of follow-up, the contour of the skull was ideal and the skin over the defect and neurologic status was intact. Due to their biocompatibility and rigidity, custom-made titanium prostheses are promising options for reconstructing complex skull defects.

“…Each material poses their own advantages and disadvantages 3 . Cranial Implants made from PMMA are stable, biocompatible, chemically inert, nonconductive, radioluent, and inexpensive and can be easily placed and modified [4][5][6] . Thus it accomplishes the requirements but durability and the reaction of the PMMA implant is questionable and technique sensitive .…”

Cranioplasty is a neurosurgical procedure done to cover the defective or deficient skull bone. The cranial reconstruction rejuvenates the patient by protecting and restore intracranial structures and pressure thus improving the esthetic appearance. Thus improves the neurological and psychological wellbeing of the patient. The blending Advancement of computer technology in medical and dental science allowed the 3D reconstruction of several anatomical structures for various medical procedures by designing the custom-made implants. Procedure: This case report describes the methodology used to design a custom-made cranial implant for a 38-year-old patient who had traumatic injury in the right temporosagital region of the skull caused by a road traffic accident . 3D reconstruction of the cranial vault was done using CAD designing and Selective laser melting (SLM) technology printing. Discussion: The presicion of the prosthesis was good thereby the surgical time was reduced and eliminates any errors in operating theatre and successfully implanted. The patient’s esthetics was restores , allowing the patient to safely perform daily activities with full confidence. Conclusion: The use of 3D reconstruction techniques in managing exhaustive surgeries aids to reduces the possibility of errors during surgery, precise and passive fit and provides better implant stability. Thus 3D printing technology has boomed its use in various field of medicine. Keywords: Cranial implants; titanium; 3D Printing; Fused deposition modelling Printing; Selective laser melting (SLM) technology.
