Simple and cost-effective approach for maxillary bilateral posterior intrusion: Nandlal Toshniwal Rural Dental College double intrusion arch
Prosthodontic rehabilitation of edentulous space is often complicated with overeruption of antagonistic tooth and often requires preprosthodontic intervention. In this context, orthodontic intrusion of the overerupted antagonistic tooth to facilitate prosthodontic rehabilitation is a desirable strategy. Without orthodontic molar intrusion or segmental surgical impaction, restoring the posterior occlusion often entails the need for significant reduction of maxillary molar crown height, with the potential need for costly iatrogenic root canal therapy and restoration. Conventional orthodontic techniques do not intrude posterior teeth effectively, and almost all methods result in anterior extrusion rather than posterior intrusion. This case report describes the treatment of a patient with supra-erupted maxillary right and left first molars intruded with Nandlal Toshniwal Rural Dental College double intrusion arch. The results showed that the biological responses of the teeth and the surrounding bony structures to the intrusion appeared normal and acceptable.
