Abstract
A dental crown analog for anchoring an orthodontic archwire to a dental implant fixture installed in a patient who is edentulous at the site where such anchorage is desired has a hollow tubular passage integral with the analog and extending mesially-distally through the analog close to an adjacent buccal or lingual surface. This passage has a slot-shaped opening at one end, the larger dimension of which is generally parallel to the adjacent surface, and the larger dimension tapers toward a smaller generally cylindrical cross-section between its ends or at the other end. Where the smaller cross section is between the ends of the passage the other end of the passage also has a slot-shaped opening. A tube for holding the archwire may be fitted in the passage, rockably mounted in the smaller portion of the passage.
