Positioning appliance for an implant-retained prosthesis for a patient with surgically and radiation-induced microstomia: A clinical report.

When treating a patient with microstomia, prosthesis design can become challenging and often requires modifications. The patient's ability to insert and remove the appliance may also be a problem. This clinical report describes the fabrication of a positioning appliance for a patient with microstomia. The appliance used the maxillary teeth as a guide to orient the prosthesis appropriately and engage the mandibular LOCATOR abutments.
