Summary The aim of this study was to collect information about the mean working time needed to accomplish the clinical procedures in applying an adhesive bridge, and to gain an insight into the factors that influence the working time. The study was carried out as part of a clinical trial. One hundred and fifty‐one patients needing one adhesive bridge were selected for this study and divided between five operators. Clinical procedures were carried out following a written protocol. The statistical method consisted of an ANOVA after log‐transformation of the working times. The total mean working time needed to accomplish the clinical procedures for adhesive bridges was 60·7 min (s.d.±16·5 min). The mean working time increased by 30% where the abutment teeth were restored with class II or class III restorations. No influence was found related to: (1) type of bridge (i.e. macromechanical versus micromechanical), (2) type of luting resin and (3) location of the bridge. A significant effect on the working times was found for: (1) operator, (2) tooth preparation and (3) occlusal adjustments. With increasing experience of the operator the median working time decreased by up to 35%. The data from this study are considered as useful basic information for efficient planning in the dental practice and for a further cost‐benefit analysis.
