dc.description.abstract OBJECTIVES: (1) Compare the relapse of corrected deep bites in three groups of patients separated by facial type (2) Determine the associations of various parameters influencing deep bite relapse. METHODS: 60 patients treated at the University of Washington were included, all with initial overbites >50%. Patients were grouped according to initial Y-axis, MPA, and LFH values. Data was collected from casts and cephalometric radiographs at three time points: pre-treatment, post-treatment, and ten years post-retention. RESULTS: Dolicocephalic subjects showed the least amount of deep bite relapse (0.1 ± 1.1 mm), while brachycephalic (1.2 ± 0.9 mm) and mesocephalic (1.4 ± 1.3 mm) subjects experienced significant relapse (p < 0.05). Intergroup comparisons revealed that the brachycephalic group had significantly more post-retention change in overbite, N-ANS, interincisal angle, and L1-MP than the dolicocephalic group (p<0.05). CONCLUSIONS: Orthodontists should consider overcorrection of overbite in brachycephalic and mesocephalic patients presenting with overbites >50%. en_US
