Treatment times for adhesive bridges.

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.

A clinical comparison of three types of resin-retained cast metal prostheses.

A preliminary clinical trial comparing three types of resin-retained cast metal FPDs was conducted. Micromechanical retainers were found to be more retentive than macromechanical retainers. The retention values in this investigation were in agreement with similar studies, but longitudinal studies are still desirable.
