Abstract:
OBJECTIVETo record and analyze the characteristics of condyle movement before and after functional treatment in Angle class II division 1 malocclusion (II(1)) patients.
METHODSTwenty Angle II(1) patients were included in the study and 20 Angle I patients without temporomandibular disorders symptoms served as controls. Computer aided diagnosis axiograph (CADIAX) was used to record the condyle movement in Angle II(1) patients and that caused by functional appliance treatment during mouth opening and closing.
RESULTSThe tracing were vertically displayed. Value Z [L: 2.21 (1.01) mm, R: 1.12 (1.02) mm] and sagittal condylar inclination [L: 12.89 (9.12) degrees, R: 12.12 (8.89) degrees] were increased significantly in Angle II(1) patients compared with those in control group (P < 0.05). After functional treatment, the condyle movement in Angle II(1) patients was close to normal (P > 0.05).
CONCLUSIONSTypical characteristics of condyle movement were found in Angle II(1) patients and it was stable and repeatable. Functional therapy had a positive effect on temporomandibular joint function in Angle II(1) patients.
