Abstract
The field of orthodontics demands versatility in appliances for faster and efficient treatment process. One such versatile auxiliary used is the Transpalatal arch for anchorage and for active tooth movements such as for correcting molar rotation and up righting, stabilization of posterior transverse dimensions during treatment, and maintenance of leeway spaces during the transition of the dentition.The process of insertion of the Transpalatal arch is cumbersome. To address these limitations, alternative methods for using the Transpalatal arch has been innovated where design experimented does not demand laborious procedures and can be done inhouse and is cost effective.There are three methods custom made Custom made Transpalatal arch is fabricated. Lingual/ Palatal surface of the molar is etched and bonding agent applied and cured. The stub of the TPA is then adapted to the tooth surface and flowable resin is applied and then cured. Preformed mesh is cut and welded onto the lingual sheath thereby converting a weldable lingual sheath into a bondable sheath. Mesh is then adapted onto the prepared tooth surface and then cured with composite. The mesh provides mechanical retention which is helpful for bonding. The custom made Transpalatal arch is now inserted. Vertical and horizontal grooves are made on the posterior side of the lingual sheath using bur. The sheath is then sandblasted to create a rough surface which provides a micromechanical retention area. This sheath is then bonded directly onto the tooth surface and Transpalatal arch inserted. The results suggest that orthodontic appliances without bands are preferable. Bonded TPA’s are less invasive and also requires less chairside time.Bonded TPA’s can overcome these issues and assist both the clinician and the patient in achieving faster orthodontic treatment and reducing discomfort. Therefore, through these innovations, a clinician can judiciously choose based on requirements and employ it effectively in orthodontic treatment.
