Resumo: | Objective: In this case report, the feasibility and precision of tridimensional (3D) virtual planning in one patient with craniofacial microsomia is tested using Nemoceph 3D-OS software (Software Nemotec SL, Madrid, Spain) to predict postoperative outcomes on hard tissue and produce CAD/CAM (Computer Aided Design/Computer Aided Manufacturing) surgical splints. Methods: The clinical protocol consists of 3D data acquisition of the craniofacial complex by cone-beam computed tomography (CBCT) and surface scanning of the plaster dental casts. The ‘‘virtual patient’’ created underwent virtual surgery and a simulation of postoperative results on hard tissues. Surgical splints were manufactured using CAD/CAM technology in order to transfer the virtual surgical plan to the operating room. Intraoperatively, both CAD/CAM and conventional surgical splints are comparable. A second set of 3D images was obtained after surgery to acquire linear measurements and compare them with measurements obtained when predicting postoperative results virtually. Results: It was found a high similarity between both types of surgical splints with equal fitting on the dental arches. The linear measurements presented some discrepancies between the actual surgical outcomes and the predicted results from the 3D virtual simulation, but caution must be taken in the analysis of these results due to several variables. Conclusions: The reported case confirms the clinical feasibility of the described computer-assisted orthognathic surgical protocol. Further progress in the development of technologies for 3D image acquisition and improvements on software programs to simulate postoperative changes on soft tissue are required. |

Métodos: o protocolo clínico usado consistiu na aquisição de dados 3D do complexo craniofacial por meio de tomografia computadorizada de feixe cônico (TCFC) e digitalização dos modelos de gesso. O “paciente” criado virtualmente foi submetido à cirurgia virtual e obteve-se uma simulação dos resultados pós-operatórios nos tecidos duros. Os splints cirúrgicos foram confeccionados usando-se a tecnologia CAD/CAM, e permitiram que o planejamento cirúrgico virtual fosse transferido para a sala cirúrgica. No transoperatório, tanto os splints CAD/CAM quanto os splints cirúrgicos convencionais mostraram-se similares. Um segundo conjunto de imagens 3D foi obtido após a cirurgia, para que medidas lineares pudessem ser obtidas e comparadas com as medidas feitas na simulação virtual dos resultados pós-operatórios. Resultados: foi encontrada uma forte semelhança entre os dois tipos de splints cirúrgicos, que se adaptaram da mesma forma nas arcadas dentárias. As medidas lineares mostraram algumas discrepâncias entre os resultados cirúrgicos reais e os resultados previstos na simulação virtual 3D; porém, a análise desses resultados requer cautela, em virtude da presença de inúmeras variáveis que podem neles interferir. Conclusões: o caso relatado no presente estudo confirma a viabilidade clínica do protocolo descrito de cirúrgica ortognática assistida por computador. Porém, ainda se faz necessária uma maior evolução no desenvolvimento de tecnologias para a aquisição de imagens 3D e nos softwares que simulam as alterações pós-operatórias nos tecidos moles.Dental Press International2016info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttp://hdl.handle.net/10316/108525http://hdl.handle.net/10316/108525https://doi.org/10.1590/2177-6709.21.1.089-100.oareng2176-9451Vale, FranciscoScherzberg, JessicaCavaleiro, JoãoSanz, DavidCaramelo, FranciscoMaló, LuísaMarcelino, João Pedroinfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2023-08-31T10:14:18Zoai:estudogeral.uc.pt:10316/108525Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T21:24:49.841720Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
