Diversifying the rehabilitation of calvarial defects

Abstract

Cranial vault defects are either congenital or acquired in origin. Cranioplasty is most commonly done in patients after trauma, decompressive craniectomies, tumor resections, infections or because of congenital malformations. The purpose of a Cranioplast is to protect the underlying brain tissues, reduce pain, and to improve the calvarial contour, symmetry, and esthetics. Rehabilitation of these defects possesses a challenge to the surgical team and prosthodontist. With advancement in three-dimensional (3D) engineering technology, the use of rapid prototyping technology (RPT) can be used in the fabrication of 3D skull eliminating conventional impression for recording defect region. Custom-made cranial prosthesis now can be fabricated using the conventional method of wax-up and lost-wax method. Case 1 had a history of road traffic accident followed by decompressive craniectomy, which led to frontoparietotemporal defect of the right side. The 3D model was fabricated using RPT technology. The wax pattern fabricated on 3D prototyped skull was contoured using digital photographic superimposition method. Case 2 had a history of trauma on the head causing intracerebral hemorrhage followed by decompressive craniectomy which led to frontoparietotemporal defect of the right side. The 3D model was fabricated using RPT. The wax pattern fabricated on 3D prototyped skull was contoured using the compass method. The use of these methods with the added advantage of RPT resulted in prosthesis with good esthetics and better fit. The contour of the prosthesis was replicated in the same manner as compared to the contralateral side. These techniques are easy to use and are less time consuming and had few chances of errors.

“…A partir de ferramentas distintas, é possível avaliar variáveis, como simetria e contorno protético, a fim de garantir um resultado estético satisfatório. Essa técnica promoveu maior grau de satisfação dos pacientes, além de proporcionar resultados mais previsíveis e precisos para a prótese (GUPTA, A. et al, 2021).…”

“…No presente estudo, observou-se que o emprego de tecnologias digitais no planejamento protético, como escaneamento, tomografias e impressão 3D, facilitou etapas importantes em relação ao design de peças complexas, desenvolvimento e prova de molde protético e guia cirúrgico(BRUCOLI et al, 2020;CEVIK;KOCACIKLI, 2020; CIOCCA, Leonardo et al, 2023;DHIMAN;BHANDARI;GABA, 2020;EO et al, 2020;GUPTA, A. et al, 2021; HEYDENRYCH; WALT, VAN DER; HEEVER,VAN DEN, 2023;JOHN;ABRAHAM; …”

“…It is radio-opaque, non-ferro-magnetic and is highly economical than other alloplasts. 5 , 6 , 7 The only disadvantage of PMMA (polymethylmethacrylate) is its residual monomer content which may hamper the healing process at the deficit area and may cause post-operative haematoma. 4 …”

Stereophotogrammetric Method for Fabrication of Cranioplast Using Digital Facial Scan Technology - A Case Report

“…The custom flask fabricated for this case helped to accommodate the entire wax pattern. [ 5 ] It allowed a uniform gypsum product around the wax pattern, thus avoiding distortion of the wax pattern. [ 7 ] It also ensures the proper polymerisation of heat cure PMMA without any water seepage and thus reduces porosities in the final prosthesis.…”
