Le, Celia; Deleat-Besson, Romain; Prieto, Juan; Brosset, Serge; Dumont, Maxime; Zhang, Winston; Cevidanes, Lucia; Bianchi, Jonas; Ruellas, Antonio

Made available in DSpace on 2022-04-28T19:49:20Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-01-01; In order to diagnose TMJ pathologies, we developed and tested a novel algorithm, MandSeg, that combines image processing and machine learning approaches for automatically segmenting the mandibular condyles and ramus. A deep neural network based on the U-Net architecture was trained for this task, using ...

Coelho, Joana; Albuquerque, Pedro Armelim; Nunes, Tiago; Kato, Renata; Garib, Daniela; Miguéis, António Carlos Eva; Corte-Real, Ana

The medico-legal identification is based on a set of discriminatory characteristics between individuals in their biological, social, cultural, religious, legal and economic framework. The purpose of this study was to characterize the biological variation, regarding gender and age, in a Por-tuguese population. A three-dimensional (3D) analysis of 215 mandibles (7–20 years old) from the database of the Laboratory...

Objective: To compare dental arch relationships in children with unilateral cleft lip and palate (UCLP) between two surgical techniques for repair of cleft lip/palate and two ages of palate repair. Settings and Sample: Dental models were taken for a group of 448 subjects at a mean age of 7 years and were evaluated by means of the Goslon Yardstick. The patients studied consisted of an initial group of 673 infant...


Reproducibility of mandibular landmarks for three-dimensional assessment

Corte-Real, Ana; Kato, Renata Mayumi; Nunes, Tiago; Vale, Francisco; Garib, Daniela

Mandible can be an elective bone for human identification. This study aimed to test the reproducibility of mandibular landmarks in three-dimensional reconstructions. Cone-beam computed tomography of 17 patients from 7 to 20 years were collected at University of Coimbra database and reconstructed in Mimics Innovation Suite 17.0. Twenty-five landmarks were demarcated for thirty measurements. Reproducibility was e...
