Space management using Transpalatal arch in mixed dentition phase: A case report

Abstract

Introduction: The early exfoliation of primary molars during the mixed dentition phase often results in disruptions to the normal development of occlusion. An alternative option for space management in the maxillary arch besides the commonly used Nance palatal holding appliance is the transpalatal arch which allows some amount of space regaining. Case report: A 9 year old female reported with a complaint of missing tooth in the upper right back tooth region since 2 years. On examination, there was premature loss of the right primary maxillary first molar causing space deficiency in the arch form. A treatment plan was made for space regaining and distalization with transpalatal arch custom made with 0.9mm stainless steel wires and soldered to the molar bands. The treatment spanned for 10 months with the eruption of the permanent successor in correct arch form. Conclusion: Although the use of transpalatal arch is limited in pediatric dentistry, it can be used for correcting minor space discrepancies of the maxillary arch. More number of cases need to be studied for extending the use of the appliance in interceptive orthodontics.
