Long-term clinical results after treatment with conical crown-retained dentures.

The clinical outcome of treatment using conical crown-retained dentures was evaluated. Of the initial 25 patients provided with 26 conical crown-retained dentures, 18 patients with 18 restorations could be examined after a time ranging between 73 and 92 months. Of the eight restorations lost, four had been changed as a result of factors that might have been related to the prosthodontic care. Most of the patients were very satisfied with the restorations both functionally and esthetically and found their chewing comfort to be better after treatment with conical crown-retained dentures. However, 50% of the patients reported speech problems related to treatment. Technical failures were not insignificant but were treatable. The survival rate after 73 to 92 months was 78.3%.
