ABSTRACT:
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.
