Device for facilitating the taking of an impression of bone portions of the mouth, and method of using same

摘要

In order to take the impression of the bony portion of a patient's mouth, and then to make an implant-type attachment using that portion of the patient's bone structure as a support, a prototype device is used which may readily be shaped to conform to the portion of the bone structure in question and then captivated in impression material such as the material used in conventional fashion, to take the impression of the rest of the patient's mouth. The device is removed from the mouth of the patient as a unit with the impression material, after which the attachment is fabricated so that a support portion thereof conforms to the shape of the device. The prototype device comprises a U-shaped flexible sheet which may readily be caused to conform to the shape of the bone structure in question, and a post member extends therefrom into the mouth of the patient, the impression material surrounding and captivating that post member.
