Abstract

Planning and surgical treatment of central giant cells granuloma using 3D printed resin prototypes

Lucas Viana Angelim*

The Central Giant Cell Granuloma (CGCG) is an intraosseous lesion that has an unknown etiology. It can be considered as a benign neoplasm and as a reactive lesion because it has a local and aggressive behavior which can also be a body reaction induced, for example, by a hemorrhage. That injury occurs more often in the mandible and particularly involves the anterior region, frequently crossing the midline. Its radiographic appearance isn’t pathognomonic, showing as lesions well-defined lesions with unilocular or multilocular radiolucency. CGCGs are classified as non-aggressive or aggressive type and, this distinction is so important because it defines the treatment protocol and helps to predict how the post-operatory will be. Nowadays, technology can assist and facilitate health specialists minimizing the costs and reducing the time that is expended. The purpose of this research is to describe a case report that reveals the usage of 3D printing resin prototype to help the planning of surgical excision of CGCG in the right maxilla. The 20-year-old female patient came to our service of Oral and Maxillofacial Surgery with a volume growth in the maxilla that could be seen in the extraoral exam. Clinically this lesion was painless and with two years of evolution that started after tooth extraction. The radiography revealed a mixed lesion in the region that displaced the third molar. Using 3D images obtained from computerized tomography, a prototype made with resin was made to help the surgical planning. The woman was submitted to general anesthesia and the surgeon operated a hemimaxillectomy with safety margins. The postoperative phase had no complications. The usage of technology benefiting the surgery can be analyzed in the case report. The careful examination of the clinical, histopathological, and radiographic findings to are essential determine the treatment that will be chosen to administer CGCGs.
