“…The fractured regions vary according to the etiology of the trauma, with the most affected ones being: body (29.5%), angle (27.3%) and condyle (21.1%) (Miloro et al, 2016). The treatment goal is to reestablish the occlusion, therefore, determining the degree of occlusal alteration caused by trauma is a crucial step to choose the best therapeutical approach (Pickrell & Hollier, 2017;Reddy et al, 2019;Ramanathan et al, 2020).…”

“…However, the ideal reduction may be difficult due to complex fracture patterns, muscle action that favors displacement and time elapsed between the trauma and the surgical procedure (Ramanathan et al, 2020). Currently, stable internal fixation is the technique of choice for simple fractures, while rigid internal fixation is indicated in cases of comminuted fractures or when segmental defects are present.…”

Mandibular fractures lead to changes in occlusion, aesthetic deformities and functional alterations, when untreated, their sequelae may cause permanent problems, leading to a more complex treatment than the acute trauma. The treatment offers challenges that can be minimized with the aid of biomodels, printed by 3D technology. This article aims to report a biomodel-assisted surgical procedure for mandibular reconstruction, arguing how these prototypes may help to achieve better outcomes. The patient was involved in an automobile accident and sought treatment for the sequelae of mandibular fractures two years after the initial trauma. The biomodel printing of her mandible allowed for the execution of surgery on the model, reestablishing correct occlusion and facial aesthetics, and helping shorten the surgical time through the pre-bending of reconstruction plates. The patient improved uneventfully. The use of biomodels must be encouraged, especially in cases where the patient shows sequelae, when the anatomical landmarks are compromised, they offer more predictability for treatment outcomes, as described on this case report.

“…Until now, IMF has been used in oral and maxillofacial surgery to treat patients with mandible fractures to remove sensitive blockages and reduce fractures. [11][12] Intermaxillary fixation is made with wires, IMF bolts and strip strips. Arch bars in particular are useful for reshaping crushed bone fragments and for immobilizing the entire mandible.…”

Aim: To evaluate the difference and functional outcome between open reduction and internal fixation (ORIF) and intermaxillary fixation (IMF) in mandibular fractures. Study Design: Retrospective study. Place and Duration of Study: Department of Oral and Maxillofacial Surgery, Faryal Dental College, Sheikhupura, Lahore from 1st February 2019 to 31st January 2021. Methodology: One hundred and fifty seven patients treated for fractures of mandible and reviewed their prognosis based on use of intermaxillary fixation after reduction of fracture. The patients were divided into two groups; Manual reduction group without the intermaxillary fixation and the intermaxillary fixation group. Results: Good results have been obtained in most patients after mandible fracture reduction. However, complications occurred in 19 (27.5%) patients in group 2 after surgery. 6 patients had an infection, 4 patients had a wound dehiscence, and 4 patients had osteomyelitis. No loosening of the mounting bolts and/or crack of the mounting plates was observed. Correct occlusion was achieved using posterior arch wires and elastic rings in 2 malocclusion patients. Occlusion failed in two patients in Group 1 due to osteomyelitis, and the second operation was performed under general anaesthesia. The mean complication severity scores for Group 1 and Group 2 were 1.37 and 1.38, respectively, with no significant difference. Conclusion: Among the patients treated with manual reduction, 2 patients had malocclusion and 1 patient required a new surgery. Such a simple mandible fracture can give good results even with manual reduction without intermaxillary fixation. For a simple mandible fracture, only manual reduction without intermaxillary fixation or intermaxillary fixation was recommended for a short time. Key words: Complication, Fracture, Internal fixation, Mandible

“…Aunque las férulas también son modelos espaciales negativos, al basarse en una posición final virtual que aún no existe, esto requiere un software de diseño 3D avanzado para realizar operaciones virtuales (16) . Los beneficios que ofrece cualquier férula son: restauración de la oclusión dental pretrauma ideal, prevención de los micromovimientos del arco en los planos sagital y horizontal, reducción de la separación lingual, que no puede verificarse intraoperatoriamente, preservación de la estabilidad del arco transversal durante la fijación de los fragmentos (20) . Ejemplo de esto fue realizando ferulas con tecnologia CAD/CAM utilizando imágenes de TC del paciente, la fractura se recreó ́ en el modelo STL generado.…”

“…Los fragmentos fracturados se redujeron virtualmente a sus características anatómicas, dejando los dientes en máxima intercuspidación. Se construyó una férula virtual interoclusal correspondiente a la oclusión previa al trauma mediante una técnica aditiva (20) . Las férulas CAD / CAM generadas por la planificación virtual preoperatoria ofrecen numerosos beneficios clínicos en comparación con las férulas convencionales generadas en laboratorio: mayor precisión en la reducción de fracturas y restauración de las características anatómicas normales de la configuración del hueso fracturado en las tres dimensiones; oclusión bucal precisa y estable, así como lingual en la fase postoperatoria; excelente ajuste de la férula a la dentición durante la reducción de la fractura; mayor comodidad del paciente durante la fabricación de férulas; y fabricación y manejo fáciles, al eliminar la necesidad de procedimientos de laboratorio engorrosos (20) .…”

En los últimos años, la tecnología y la medicina han podido complementarse para la optimización de tiempo, conocimientos y recursos, aumentando la posibilidad de tratamientos personalizados en más pacientes. A nivel maxilofacial, la reconstrucción de defectos mandibulares se ha visto en la necesidad de progresar sus técnicas debido a la serie de orígenes que afectan el hueso mandibular de manera drástica, como lesiones traumáticas, cáncer, infecciones, enfermedad congénita u otros, y las innumerables consecuencias tanto estéticas como funcionales, restringiendo significativamente la calidad de vida. El objetivo de este artículo es revisar conceptos básicos del uso de tecnologías de impresión 3D en la reconstrucción mandibular. La impresión 3D ha aparecido en diversos ámbitos, siendo en el área de la medicina, un aporte fundamental para la creación de formas anatómicas de alta precisión con el que se pueden diseñar objetos con reproducción de detalles de manera rápida, luego de una serie de pasos que incluyen la obtención de una imagen radiográfica, uso de software y reparación de archivos, y la obtención de un modelo tridimensional. Los últimos estudios han validado el uso de impresiones 3D para una reconstrucción mandibular, con claros beneficios de costos y calidad de detalles. Es necesario crear un enfoque en las técnicas quirúrgicas utilizadas con un objeto impreso tridimensionalmente y un análisis post operatorio de los pacientes sometidos a estos procedimientos más allá de los detalles técnicos.
