Objectives: This study was undertaken to evaluate the distalization efficacy of four different intraoral assemblies namely: Jones jig, Lokar distalizer, Distal Jet and Samarium Cobalt magnets. Materials and methods: The present study was conducted on maxillary arches of 10 patients of either sex, within the age group of 10 to 14 years, requiring orthodontic therapy. The sample was then divided into two groups: Five subjects (group A) were given Distal Jet on right side and Jones Jig on left side, five subjects (group B) were given Lokar distalizer on right side and Samarium Cobalt magnet on left side. Cephalometric and model analysis were used to measure skeletal and dental changes. Results: In all the patients, a class I or super class I relationship was obtained within a mean time of 14.2 weeks. The overall mean distalization and distal tipping brought about by the Lokar distalizer was the maximum compared to the other systems. The magnets exhibited the least amount of distalization and the Distal jet produced the least amount of tipping. Conclusion: On a comparative basis, the palatally acting Distal Jet proved its supremacy over the buccal assemblies because the force was directed closer to the center of the resistance of the tooth. Further, the NiTi open coil spring-based systems displayed more amount of distalization than the Magnet-based system.
