CLINICAL-PERFORMANCE OF DIFFERENT POST AND CORE SYSTEMS - RESULTS OF A PILOT-STUDY

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%) we re noticed. Eight teeth could be rerestored and six teeth had to be ex tracted. However, when correction was made for teeth with a bad initia l prognosis and for extractions not related to the build-up restoratio n, eight failures remained caused by failure of the build-up (7-5%). T he Dentatus posts seemed to increase the risk for failure.
