Rehabilitation of edentulous space with prosthesis is often complicated with overeruption of antagonistic tooth and usually requires pre prosthodontic intervention. Therefore,= orthodontic intrusion of the overerupted tooth to facilitate prosthodontic rehabilitation is required. Without orthodontic molar intrusion 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 first molar which was intruded with RA Molar intrusion appliance .The results showed that the biological responses of the teeth and the surrounding bony structures to the intrusion appeared normal and acceptable.
