Summary During the period 1974‐1986, 112 post and core build‐ups were inserted in 74 patients. The build‐ups consisted of a metal prefabricated post (Dentatus, Unimetric or Radix) in combination with a composite core. After an average follow‐up period of 7.9 years, 14 failures (12.5%) were noticed. Eight teeth could be rerestored and six teeth had to be extracted. However, when correction was made for teeth with a bad initial prognosis and for extractions not related to the build‐up restoration, eight failures remained caused by failure of the build‐up (7.5%). The Dentatus posts seemed to increase the risk for failure.
