Avulsed immature incisor: from computed tomography to finite element analysis

Dental trauma represents the second etiology for tooth loss. Understanding of its mechanism in relation to ora-facial structures is essential for clinical reason. Due to its mechanical nature, the trauma can be investigated accurately using mathematical methods (finite element methods). A geometrical model was obtained from the computer tomograph scans of a immature upper incisor, further processed in dedicated FEA (Finite Element Analysis) software. Similar results with previous studies were achieved, confirming the validity of the model and the reliability of the path from DICOM (Digital Imaging and Communications in Medicine) files to compliant finite element method object. The results sustain the epidemiological findings, enamel fractures being detected more often than other clinical forms.
