          Abstract

          SUMMARY: Recent technical and technological advancements in orthognathic surgery concepts, intricate in the diagnosis and treatment planning for corrections of dento-facial deformities, have achieved stable oro-dental functional occlusion and facial esthetic harmony. Undeniably, this can be attributed to the integration of modern, innovative and advanced facial analysis and computer-aided imaging exams into well-orchestrated and executed orthodontic and surgical methods. Three-Dimensional (3-D) virtual planning is a fine example. Today, the acquisition of 3-D images of a patient’s craniofacial complex via cone-beam computed tomography (CBCT), supported by software tools allowing the construction of 3-D dynamic and interactive visual models, eliminates the uncertainty experienced with two-dimensional images. Thereby allowing for a more accurate or predictable treatment plan and efficient surgery, especially for patients with complex dento-facial deformities. This review article aims to describe the current benefits as well as shortcomings of 3-D virtual planning via discussing examples and illustrations from orthognathic procedures, attained from the reported English and Spanish literature during the last 10 years. It is designed to deliver updated and practical guidelines for dental practitioners and specialists (particularly, oral and maxillofacial), as well as researchers involved in 3-D virtual approaches as an alternative to conventional/traditional surgical planning; thereby validating its superiority or benefits in terms of outcome prediction for soft and hard tissues, operational timeand cost-effectiveness; for its integration in day-to-day practise.

          RESUMEN: Los recientes avances técnicos y tecnológicos en los conceptos de la cirugía ortognática, involucrados en la planificación del diagnóstico y tratamiento para la corrección de deformidades dento-faciales han sido notablemente considerables en lograr una oclusión oro-dental funcional y una estética facial armónica. Innegablemente, esto se puede atribuir a la integración de análisis faciales avanzados, modernos e innovadores y exámenes de imágenes asistidos por computadora a métodos ortodonticos y quirúrgicos bien orquestados y ejecutados. La planificación virtual tri-dimensional (3-D) es un buen ejemplo. Hoy, la adquisición de imágenes 3-D del complejo cranio-facial de pacientes vía tomografía computarizada cone beam (TCCB), apoyada por herramientas computacionales, permite la construcción de modelos visuales 3-D dinámicos e interactivos, eliminando la incertidumbre experimentada con las imágenes bi-dimensionales. Permitiendo, de este modo, un plan de tratamiento más preciso o predecible y una cirugía más eficaz, especialmente para pacientes con deformaciones dento-faciales complejas. Este artículo de revisión tiene como objetivo el describir los actuales beneficios, así como las limitaciones de la planificación virtual a través de la discusión de ejemplos de procedimientos ortognáticos, obtenidos de la literatura reportada en inglés y español durante los últimos 10 años. Fue diseñado para entregar una actualización resumida y una guía práctica para los practicantes y especialistas interesados (particularmente, oro y maxilofaciales), explícitamente, así como a los investigadores involucrados en aproximaciones 3-D como una alternativa a la planificación quirúrgica convencional/tradicional; validando así su superioridad o beneficios en términos de predicción de resultados para tejidos blandos y duros, efectividad en tiempo operacional y costos; para su integración en la práctica cotidiana.

            Three-dimensional treatment planning of orthognathic surgery in the era of virtual imaging.

            The aim of this report was to present an integrated 3-dimensional (3D) virtual approach toward cone-beam computed tomography-based treatment planning of orthognathic surgery in the clinical routine. We have described the different stages of the workflow process for routine 3D virtual treatment planning of orthognathic surgery: 1) image acquisition for 3D virtual orthognathic surgery; 2) processing of acquired image data toward a 3D virtual augmented model of the patient's head; 3) 3D virtual diagnosis of the patient; 4) 3D virtual treatment planning of orthognathic surgery; 5) 3D virtual treatment planning communication; 6) 3D splint manufacturing; 7) 3D virtual treatment planning transfer to the operating room; and 8) 3D virtual treatment outcome evaluation. The potential benefits and actual limits of an integrated 3D virtual approach for the treatment of the patient with a maxillofacial deformity are discussed comprehensively from our experience using 3D virtual treatment planning clinically.

              3D planning in orthognathic surgery: CAD/CAM surgical splints and prediction of the soft and hard tissues results - our experience in 16 cases.

              The aim of this article is to determine the advantages of 3D planning in predicting postoperative results and manufacturing surgical splints using CAD/CAM (Computer Aided Design/Computer Aided Manufacturing) technology in orthognathic surgery when the software program Simplant OMS 10.1 (Materialise(®), Leuven, Belgium) was used for the purpose of this study which was carried out on 16 patients. A conventional preoperative treatment plan was devised for each patient following our Centre's standard protocol, and surgical splints were manufactured. These splints were used as study controls. The preoperative treatment plans devised were then transferred to a 3D-virtual environment on a personal computer (PC). Surgery was simulated, the prediction of results on soft and hard tissue produced, and surgical splints manufactured using CAD/CAM technology. In the operating room, both types of surgical splints were compared and the degree of similitude in results obtained in three planes was calculated. The maxillary osteotomy line was taken as the point of reference. The level of concordance was used to compare the surgical splints. Three months after surgery a second set of 3D images were obtained and used to obtain linear and angular measurements on screen. Using the Intraclass Correlation Coefficient these postoperative measurements were compared with the measurements obtained when predicting postoperative results. Results showed that a high degree of correlation in 15 of the 16 cases. A high coefficient of correlation was obtained in the majority of predictions of results in hard tissue, although less precise results were obtained in measurements in soft tissue in the labial area. The study shows that the software program used in the study is reliable for 3D planning and for the manufacture of surgical splints using CAD/CAM technology. Nevertheless, further progress in the development of technologies for the acquisition of 3D images, new versions of software programs, and further studies of objective data are necessary to increase precision in computerised 3D planning.
