Graph illustrating relative repair strengths using only 1 lb/0.79 mm2 (5.68 MPa) representing 1/4 pressure and 2.5 lbs/0.79 mm2 (14 MPa) representing 2/3 pressure instead of 4 lbs/0.79 mm2 condensation pressure and only 1 round of 8 condensation thrusts held at 2 seconds each (total 16 seconds) instead of the 24 thrusts (total 48 seconds) reducing the cumulative condensation pressure holding time to 1/3. The three groups produced significant repair strength reductions from the control and were not statistically different from each other. This would indicate that adequate condensation pressure and sufficient condensation thrust dwell time were both important for maximum bond strength. Brackets on the bars indicate 95% confidence intervals.
