In addition, 3 was extruded by removal the partial denture as an anchorage.<BR>Discussion: The clasp of the upper first molar was broken three years after prosthetic treatment. After that, there has been no specific trouble.<BR>Conclusion: Removal of the partial denture was used as an anchorage to apply the orthodontic extrusion method over the maxillary left side canine. Through this method, we were able to perform conservative procedures for the treatment of the deep caries lesion observed on this tooth.
