Figure 8: The graph presents mean values (in Newtons) obtained from retention testing after three different surface treatments. Group A – Sandblasting, Group B – Sandblasting and Laser etching, Group C – Sandblasting and Spark Erosion. Error bars indicate standard deviation. *Significant differences compared to Group A (P ≤ 0.05). Results of retention testing of samples after three different surface treatments
