title: Impression techniques for preparations with shoulders.
abstract: An impression technique useful for both individual or multiple preparations with shoulders is described. This method reproduces the entire maxillary arch in one impression, which facilitates development of satisfactory occlusion for the patient. In addition, an impression technique that simultaneously reproduces the gingival margins of tooth preparations and the edentulous ridges is described. A master cast of the entire maxillary arch can be obtained in one appointment.
