Assessment of grinding patterns with the BruxChecker
Journal Title: Prosthodontics - Year 2016, Vol 66, Issue 4
Abstract
Introduction. Occlusal analysis is necessary in planning of prosthetic treatment. Clinical examination and assessment of models in articulator may be inadequate to detect occlusal interferences, which are present during parafunctional movements only. Aim of the study. The aim of the study was to determine whether clinically observed grinding patterns are different from those registered during sleep grinding. Material and methods. 48 patients (34 women and 14 men) were selected for the study. There were 38 patients with “possible” bruxism among them. In all patients clinical and instrumental examination of grinding patterns was performed. For clinical assessment, two-sided colour articulating paper was used. Instrumental examination consisted of registration of maximum intercuspation and sleep grinding with the BruxChecker. Results. In clinical examination right-sided canine guidance (CG) was the most frequent (65.63%). Canine-premolar (CPG) and caninepremolar-molar guidance patterns accounted for 18.75% and 15.63%, respectively. For BruxChecker used during one night, inverse proportions were obtained: 16.13% (CG), 22.58% (CPG), 61.29% (CPMG). Clinical and instrumental assessment were statistically different (p<0.0233). Strength of association between the two assessments of 0.10 was expressed by Kappa coefficient. Conclusions. Grinding patterns observed clinically are different from those generated during sleep grinding.
