Introduction: In interceptive orthodontics, the treatment of transverse maxillary deficiency is essential to properly guide bone and dental development in growing patients, accurate assessment of maxillary expansion allows for effective and personalized interventions, among the most commonly used devices are the Quad Helix, which uses helical wires to generate gradual expansion, and the Nitanium Palatal Expander-2, which takes advantage of the shape memory of nickel-titanium for constant and controlled activation, both devices offer effective solutions to correct transverse malocclusions, their clinical comparison is crucial to determine the best therapeutic option according to the patient's needs. Materials and methods: This review, based on the PRISMA guidelines, analyzes the comparison between the Quad Helix and the Nitanium Palatal Expander using 30 studies selected from specialized scientific databases between 2020 and 2025. Result: This study analyzes the influence of the Quad Helix and Nitanium Palatal Expander devices in the correction of maxillary transverse deficiency, highlighting how each has transformed the planning and execution of orthodontic treatments. Their effectiveness in maxillary expansion, their impact on improving facial aesthetics, correcting crossbite, and optimizing craniofacial development in young patients are examined. Conclusion: The comparison between the Quad Helix and the Nitanium Palatal Expander has shown that both devices are effective in maxillary expansion and correcting transverse malocclusionsKeywords: dental management, neonatal teeth, pediatric dentistry.
