Agb. Mentink et al., CLINICAL-PERFORMANCE OF DIFFERENT POST AND CORE SYSTEMS - RESULTS OF A PILOT-STUDY, Journal of oral rehabilitation, 20(6), 1993, pp. 577-584
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.
