Panoramic radiographs: necessary for edentulous patients?

With recent concern about the cumulative effects of radiation exposure, routine radiographic examination of edentulous patients is being questioned. While the present study reports a lower incidence of positive findings than previous panoramic surveys, we still find potentially complicating conditions. Radiographic examination of new edentulous patients still appears warranted.

Olfaction through oral tracheal breathing tube.

Cancer of the larynx has approximately a 90% cure rate if detected early. Advanced lesions are treated surgically by removing the larynx and creating a stoma that joins the trachea. Although speech can be learned, the patient's ability to smell is permanently interrupted. This technique article describes fabrication of a simple device that permits olfaction by a laryngectomee.

Implant transfer coping verification jig.

Osseointegrated implants provide a treatment modality that should be considered for the edentulous and partially edentulous patient because of the high predictability of success. This technique article describes the fabrication of a verification jig that holds the transfer copings together in the same spatial relationship. The transfer copings can be splinted on the working cast and returned to the mouth to confirm the accuracy of the working cast.

Stabilized record base for maxillary removable partial denture obturator.

Accurate maxillomandibular jaw relation records are enhanced by a stabilized framework used to support the occlusal rim and recording medium. Stability of the framework is often lost on the defect side because of the size of the surgical defect and/or number of missing teeth. This article introduces a technique that uses a record base stabilized with a soft resilient material that permits easy removal and replacement of the framework on the altered master cast without damage.
