Abstract
Orthodontic treatment of the patient with severe teeth attrition was performed with the provisional restorations to recover occlusal vertical dimension. The increase in VDO causes posterior mandibular rotation and the increase in overjet. The overjet correction is one of the main goals of the orthodontic treatment in these patients. The anterior mandibular position was obtained at the end of orthodontic treatment. Condylar positions were assessed immediately after the bite raising procedure and after the completion of treatment. Both CBCTs of the temporomandibular joints and the Joint vibration analysis (JVA) were performed. Coronal views of the CBCTs of TMJs and zoomed vibration views of the JVA of TMJs are essential in assessment of the condylar instability.
Highlights
Cases with severe attrition present challenge to orthodontist as are related to a loss of the occlusal vertical dimension (VDO) [1]
After the restorations were put in place the CBCT of the TMJs was made as well as the Joint Vibration Analysis procedure
There are typical waveform patterns seen in Joint Vibration analysis, which correspond to different internal derangements
Summary
Cases with severe attrition present challenge to orthodontist as are related to a loss of the occlusal vertical dimension (VDO) [1]. Various techniques are used to assess the condylar position in CBCT images of temporomandibular joints [6,7], emphasizing the sagittal and axial views as the main point. The aim of this article is to present the case of practical implementation of the joint vibrant analysis procedure in TM joint of the patient undergoing orthodontic treatment.
