Application of cast magnetic attachments to sectional complete dentures for a patient with microstomia: a clinical report.

Patients with microstomia who must wear removable dental prostheses often state that they are unable to insert or remove the prosthesis because of the constricted opening of the oral cavity. This article presents a cast iron-platinum magnetic attachment system applied to sectional collapsed complete dentures for an edentulous patient with microstomia. With the use of lingual and palatal midline hinges and a cast iron-platinum magnetic attachment, the sectional prosthesis was successfully and easily inserted and provided adequate function in the patient's mouth.
