Summary A group consisting of forty patients received a clinical and radiological re‐examination, of a cross‐sectional type, to examine the effects of pinledge‐crowns on teeth and periodontal tissues. The mean age of the material, which consisted of patients treated at the Department of Prosthetics, University of Umea, during the period February 1969‐November 1971, was 48.6 years (18 ± 22°). In these patients fifty‐one pinledge‐crowns had been inserted, in 88 % of the cases on a canine tooth. In every person, the contralateral tooth served as a control tooth. The teeth were examined with regard to the frequency of failure (expressed as failure rate %/year), the presence of caries, and the periodontal status. The results showed that of the total number of pinledge‐crowns (fifty‐one), twelve had been removed before the time of examination. At the examination it was found that one crown had extensive caries, which required a revision of the crown, and one tooth had a non‐sensitive pulp with a periapical osteitis. These fourteen (27.5%) pinledge‐crowns were classified as failures. The value of the failure rate expressed as %/year was, after 8 years, 3.43 pinledge/year or 3.13, if the patient was used as a unit. Concerning the periodontal effects, the difference between teeth fitted with pinledge‐crowns and control teeth was small.
