- (1)
- The number of impulses, performed on the bridge with a clinical removal tool, is a more reliable index of retrievability, compared to the measured force.
- (2)
- The abutment height and taper angle have a higher influence on copings retentiveness than the luting agent.
- (3)
- The best compromise for stability and retrievability consists of a long, slightly tapered abutment, cemented with a temporary cement.
