ABSTRACT 

Improving occlusion and tooth alignment can be achieved through orthodontic treatment. Orthodontic appliances can also correct crowded teeth, which are common in Indonesia.The aim of this study is to assess the effectiveness of using expansion plates to create space and simple springs to correct the malposition of anterior teeth in the upper and lower jaws,specifically teeth 11, 31, and 41. A 22-year-old female patient with an overjetof 4.2 mm and an overbite of 2.7 mm. First molar relationship on the right and left sides: Angle's Class I. Canine relationship on the right and left sides: Class I. Malposition of the patient's  individual  teeth:  11  (distolabioversion),  15  (mesiopalatotorsion),  23  (mesiolabioversion),  25  (mesiopalatotorsion),  31 (mesiolingualversion), 33 (mesiolabiotorsion), and 41 (distolabioversion). Lateral expansion of 0.85 mm  will be performed andtooth  malpositions  will  be  corrected  using  an  active  plate  in  the  form of  a  simple  spring  on  teeth  11,  21,  31,  and  41.Tooth malpositions  on  elements  11  distolabioversion  (corrected),  31  mesiolingualversion  (corrected),  and  41  distolabioversion (corrected). During visits 16 to 20, the operator performed retraction by activating a labial arch. There was a change in overjet from 4.2 mm to 3.15 mm.The treatment was effective in correcting the malposition of teeth 11, 31, and 41. The patient exhibited tooth movement mesially towards the labial direction, thus correcting the patient's teeth towards the ideal position
