Retrospective clinical study of tooth‐supported single crowns: A multifactor analysis

Abstract The purpose of the study was to investigate the influence of multiple factors on the survival of tooth‐supported single crowns and assess the biological and technical complications. This retrospective study included patients rehabilitated with single crowns with a minimum follow‐up time of 6 months after delivery. The cumulative survival rate was calculated over the maximum period of follow‐up time and reported in a life‐table survival analysis. Univariate and multivariate Cox regression was used to evaluate the associations between clinical covariates and crown failure. The included cohort group consisted of 1037 single crowns delivered in 401 patients and followed for a mean of 134.8 ± 80.2 months. Cumulative survival rate was 89.9% and 80.9% after 5 and 10 years and 70.5% and 61.8% after 15 and 20 years, respectively. The main reasons for single crown failure were loss of retention, tooth loss, and fracture. Anterior placement, non‐vital abutments, and bruxism significantly influenced the survival of single crowns. The survival of single crowns was not influenced by patient's age and sex, location of the crowns in relation to the jaws, type of tooth, presence of post and core, and type of crown material, treatment providers, or smoking. Anterior placement, non‐vital abutments, and bruxism are factors suggested to increase the risk of single crown failure and the prevalence of technical and biological complications.
