Abstract

Background: The treatment of Class II malocclusions has always been a subject of great interest for orthodontists. The use of distalization mechanics to correct Class II malocclusions is a common treatment modality. Many devices have been developed and used to distalize the maxillary molars and show positive clinical results.
Aim of the Work: The aim of this study was to evaluate the rate of tooth movement on digital casts caused by distalization of maxillary molars using steel bar distalizer in the treatment of class II malocclusion.
Materials and Methods: Twenty patients with age ranging from 15 to 30 years were recruited from the out-patient clinic of the Orthodontic Department of the Faculty of Dentistry Ain-Shams University. All patients required maxillary molar distalization as part of their orthodontic treatment plan. Impression for appliance fabrication was done then mini-screws were inserted after appliance cementation. The rate of maxillary first molar movement was assessed through the analysis of successive digital model scans taken every 4 weeks.
Results: The changes accompanying the maxillary first molar distalization were evaluated by analyzing digital models showed the mean rate of tooth movement was 0.3 mm/month.
Conclusion: The steel bar distalizer is an efficient and cheaper alternative in maxillary molar distalization.
