Resumen
Objectives:
The aim of this work has been a verification possibility to use 3D spin echo magnetic resonance imaging techniques in the dentistry within the scope of a dimensional imaging of the inner spaces of teeth during an prosthetic procedure.
Methods:
6 extracted molar teeth were used after preparation for the inner root canals fixations. Magnetic resonance (MR) measurements were carried out on a 4.7 T MRI system with Maran DRX console and home built actively shielded gradient coils and rf probe head.
Results:
Research proceedings made it possible to compare the quality of internal tooth space after preparation for inner root canals fixations constructed using both classical methods (polymer mass impression) and non-imressional methods (MRI representation) Conclusions:
A numerical model of prepared root canals obtained with the method of the magnetic resonance visualization may constitute in the future a basis for a non-impressional technique of imaging, usefull for dental prosthetics. A numerical model of the prepared root canals obtained with the method of the magnetic resonance visualization imaging combined with the method of images analysis, may in the future constitute a basis for an automatic 3D modelling of the inner root canals fixations, supported with computer applications dedicated for the designing purposes (CAD-computer aided design).
