Bennett movement of mandible: a comparison between traditional methods and a 64-slices ct scanner

摘要

Objective: compare the values of the Bennett angle measured by an average value articulator with the ones measured by a 64 slices Computed Tomography (CT).udMethods: we have studied a patient aged 72. Maxillary and mandibular impressions were obtained from the patient and placed on the average value articulator using wax-ups and a facial arch in order to perform the Bennett angle measurations by such device. CT measurements were carried out using templates in order to block the Patient in the correct mandibular position.udResults: our study has demonstrated that the measurements of the Bennett angle obtained with the average value articulator are consistent with the ones obtained with the 64 slices CT.udConclusions: CT scanning is a useful method, alternative to conventional procedures, as the average value articulator for Bennett angle measurements, and it could become an important diagnostic tool in the gnathological and rehabilitative area.
