Assessment of 3D scanners for modeling pectus carinatum corrective bar
Moreira, António H. J.; Fonseca, João Gomes; Rodrigues, Pedro L.; Fonseca, Jaime C.; Pinho, A. C. M.; Correia-Pinto, Jorge; F. Rodrigues, NunoPectus Carinatum (PC) is a chest deformity consisting on the anterior protrusion of the sternum and adjacent costal cartilages. Non-operative corrections, such as the orthotic compression brace, require previous information of the patient chest surface, to improve the overall brace fit. This paper focuses on the validation of the Kinect scanner for the modelling of an orthotic compression brace for the correcti...
Automatic modeling of an orthotic bracing for nonoperative correction of pectus...
Vilaça, João L.; L. Rodrigues, Pedro; Moreira, António H. J.; Fonseca, João Gomes; Pinho, A. C. M.; Fonseca, Jaime C.; F. Rodrigues, NunoPectus Carinatum is a deformity of the chest wall, characterized by an anterior protrusion of the sternum, often corrected surgically due to cosmetic motivation. This work presents an alternative approach to the current open surgery option, proposing a novel technique based on a personalized orthosis. Two different processes for the orthosis’ personalization are presented. One based on a 3D laser scan of the pa...
An Electromagnetic Tracker System for the design of a dental superstructure
Moreira, António H . J .; Queirós, Sandro; F. Rodrigues, Nuno; Pinho, A. C. M.; Fonseca, Jaime C.; Vilaça, João L .Nowadays, different techniques are available for manufacturing full-arch implant-supported prosthesis, many of them based on an impression procedure. Nevertheless, the long-term success of the prosthesis is highly influenced by the accuracy during such process, being affected by factors such as the impression material, implant position, angulation and depth. This paper investigates the feasibility of a 3D elect...
Artificial neural networks for automatic modelling of the pectus excavatum corr...
Rodrigues, Pedro L.; Moreira, António H.J.; F. Rodrigues, Nuno; Pinho, A. C. M.; Fonseca, Jaime C.; Correia-Pinto, Jorge; Vilaça, João L.Pectus excavatum is the most common deformity of the thorax and usually comprises Computed Tomography (CT) examination for pre-operative diagnosis. Aiming at the elimination of the high amounts of CT radiation exposure, this work presents a new methodology for the replacement of CT by a laser scanner (radiation-free) in the treatment of pectus excavatum using personally modeled prosthesis. The complete eliminat...
