Abstract:
OBJECTIVETo investigate the clinical effects of facemask protraction on skeletal Class III adult patients.
METHODSTotally 15 skeletal Class III patients (male 7, female 8, aged 18 - 24 years) were included in the study. Removable and fixed appliances were used in the upper or lower arches. Facemask protraction was used at night for about 7 months and Class III elastics were worn during the day. The total treatment time was 24 mouths on average. Cephalometric analysis was carried out before and after treatment.
RESULTSThe profile was greatly improved and Class I molar relationship was achieved. SNA angle was increased from (79.6 ± 3.7)° to (81.1 ± 3.8)°. SNB angle was decreased from (83.5 ± 3.3)° to (82.6 ± 3.6)°. ANB angle was increased from (-4.1 ± 2.0)° to (-1.5 ± 1.8)°.
CONCLUSIONSProtraction was effective in the treatment of skeletal Class III adult patients.
