“…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.

Cranial vault defects may be acquired or congenital in origin. Rehabilitation of these patients often poses challenge to the operating team and prosthodontist. Polymethylmethacrylate is a commonly used alloplastic graft material which is used for the fabrication of cranial prosthesis. Nowadays, with the advancement in the bioengineering, custom-made template and cranial prosthesis can be made by rapid prototyping technology (RPT) by patient three-dimensional (3D) computed tomography (CT) scan images. This series of two cases explained two different techniques for the rehabilitation of the patient with frontotemporoparietal cranial defect. Case 1 had a history of cerebrovascular accident, followed by decompression craniotomy which led to frontotemporoparietal defect of the left side. This defect area was associated with the cerebrospinal fluid accumulation which made delineation of underlying bony margins difficult and interfered with conventional impression procedures. Case 2 had a road traffic accident which led to intracerebral hemorrhage followed by decompression craniotomy which resulted in frontotemporoparietal defect of the right side. The patient had a poor neuromuscular control which impedes with the upright posture of the head during impression making of the defect area. Therefore, these cases were planned to rehabilitate by RPT. In these techniques, the prosthesis was made using custom-made skull template produced by RPT, using the data of 3D-CT scan images. This technique resulted in the prosthesis with good esthetics and better fit of the prosthesis. The contours of the prosthesis were replicated in the same manner as compared to the contralateral side. RPT is an additive manufacturing technology which is now used in the field of dentistry too. This technique is easy to use; fabricate prosthesis with high precision is less time-consuming and has fewer chances of error.

“…Metals such as tantalum, titanium, austenite stainless steel, and vitallium display the benefit of being hard, malleable, and easily available, but their high thermal conductivity may precipitate headaches and other neurological symptoms. 7 Silicones and polyethylene are tissue compatible but their flexibility compromises pro-tection in cranial defects. 5 Self-polymerizing acrylic resin is less inert, strong, and has poor thermal and electrical conductivity.…”

Objectives: Immediate post-operative reconstruction of calvarial bone by cranioplasty prosthesis in calvarial bone fibrous dysplasia. An easy and economical method for reconstruction of the defect. Methods: Surgical excision of right parietal cranial space occupied lesion was performed followed by fabrication of immediate postoperative period cranioplasty prosthesis by using clear heat polymerized polymethylmethacrylate. Results: The cranial defect created during excision of calvarial bone fibrous dysplasia was immediately replaced by cranioplasty prosthesis which was fabricated in the immediate post-operative period using heat polymethylmethacrylate. Conclusions: Polymethylmethacrylate is a very reliable thermoplastic material that can be prefabricated or even placed immediately after post-operative period to produce a suitable prosthesis. Polymethylmethacrylate implants have been outmoded by computer-aided design and computer-aided manufacturing and newer 3-dimensional printed implants, but these newer methods are accompanied by higher expenses and timing issues.
