Long-term experience with telescopically retained overdentures (double crown technique).
To evaluate the long term results of telescopically retained overdentures, 92 patients with a total of 106 overdentures on 236 teeth were examined after two to eleven years. Thirty-three teeth were lost during the follow-up period. A higher tooth survival rate of the double-crowned teeth was found under mandibular overdentures (92%) than under maxillary overdentures (86%) after five years. The palladium-silver-alloy used seemed to be more suitable for telescopic crowns than the use of precious gold-copper-alloys because of tarnishing the latter alloys.
