Occlusion and Articulation in Bruxism and Bruxomania Investigated with the System T-scan Iii

Aim: To be analyzed common features of occlusal relationships in patients with bruxism and bruxomania at maximum intercuspation (MIP) and eccentric jaw movements. Materials and Methods: 30 patients (22 women and 8 men, mean aged of 42,8 ± 13,3) with bruxism and/or bruxomania are examined with the system T-Scan III. Sequence of records is at maximum intercuspation (MIP); in manual leading to central relation and in eccentric jaw movements. In the same sequence is investigated control group 30 people (15 women and 15 men) aged between 21 and 45 who didn’t have bruxism and/or bruxomania and dentition is preserved. Results: In the control group 85% of cases there is a balance of forces in both halves of the dental arch. In patients with bruxism is established uneven distribution of forces in MIP and articulation blockages (95%). There are three major reasons that impede spontaneous bilateral closing force outliers (93% of cases); low force outliers (82%) and presence of interceptive contacts and sliding occurring in the beginning of occlusion time until MIP (in all patients). Conclusions: In order to achieve a balanced occlusion in patients with bruxism and/or bruxomania required are correct diagnosis, registration and removal of preliminary contacts, articulation blockages and infraocclusion. Occlusal analysis is objective and an indicator of subsequent treatment only when it is a combination of clinical, instrumental and computerized occlusal analysis.
