Aim of this cross sectional study was to compare the bite force and the individual tooth load among three groups of patients: cases finished with the Self ligation appliance (Damon-Q®, 0.022”X0.028” prescription) cases finished with the MBT (McLaughlin, Bennett and Trevisi) appliance system (0.022”X0.028”prescription) and orthodontically untreated cases using T-Scan® 9.0 version.
A sample size of sixty non-extraction cases were divided equally into three groups – Group 1: patients treated with Self-ligation appliance (Damon Q®), Group 2: cases treated with the MBT prescription and Group 3: untreated subjects with Class I canine and molar relationship who were used as the control group. The bite force and distribution of force was measured on the right and left side as well as individual tooth loads were measured using the T-Scan® 9.0 device and inter-and intra-group comparisons made using Paired t-Test, ANOVA and Chi-square test.
The bite forces were balanced on both the sides in cases treated with Self-ligation and MBT appliance. The Self-ligation finishes were marginally better than the MBT group but the difference was statistically insignificant.
Orthodontically treated individuals had a better (or more even) bite force distribution compared to untreated participants.
