Indian Journal of Basic and Applied Medical Research , March 2015: Vol.-4, Issue- 2, P. 497-501 Case report: Intra-arch non-compliant mechanics for maxillary 2nd molar buccal crossbite: A transpalatal arch with L-Loop 1Dr.Renuka 1Assistant 2Head Patel,2Dr.Falguni Mehta,3Dr.Shivam Mehta,4Dr.Swati Khonde professor, Department of orthodontics,govt.Dental college and hospital,Ahmedabad , India and professor, Department of orthodontics,govt.Dental college and hospital,Ahmedabad, India 3P.G. part-3, Department of orthodontics,govt.Dental college and hospital,Ahmedabad, India 4P.G. part-2, Department of orthodontics,govt.Dental college and hospital,Ahmedabad, India Corresponding author: Dr. Renuka Patel Abstract: For over a decade, various modified appliances have been described which are placed intraorally to make a treatment successful independent of patient compliance. Many cases are seen with 2 nd molar buccal crossbite in routine clinical practice, adding significantly to treatment time. Different methods have been suggested to correct it, but a better method would be to correct it without extrusion. So in the present article we have modified the transpalatal arch in a way that its middle loop is directed distally with two additional L-loops directed mesially, E-chain is connected to 2nd molar to correct it during any phase of orthodontic treatment when mandibular arch is well-aligned. Key Words: Cross bite,Transpalatal arch with L-Loop,E-chain
