## 3 Results  
At buccal, the mean gingival thickness for the 30\({}^{\circ}\) provisional was \(0.941\pm 0.530\) mm. The gum was augmented by \(1.196\pm 0.490\) mm when there was a change to a 60\({}^{\circ}\) provisional. Thus, the greater the angle of the prosthetic emergence of the provisional is, the greater the gingival thickness, with the mean difference in the gum being \(0.255\pm 0.381\) mm, thereby making this result statistically significant (\(p=0.001\); \(t\)-test). At the lingual position, the mean gingival thickness for the 30\({}^{\circ}\) provisional was \(1.107\pm 0.494\) mm, and there was an increase of \(1.145\pm 0.394\) mm with the 60\({}^{\circ}\) provisional. The mean difference in the gum was \(0.038\pm 0.381\) mm. However, in this case, there was no statistically significant difference (\(p=0.600\); \(t\)-test) (Table 1). The differences in the buccal and lingual results show that the gingival thickness depends on specific changes in the emerging prosthetic angle in the provisional (\(p=0.012\); test F), but this dependence is a particular feature of the area where the measurement was carried out (\(p=0.022\); test F). It was shown that in buccal, a 60\({}^{\circ}\) provisional suggests a greater gingival thickness than a 30\({}^{\circ}\) provisional, whereas in lingual, this difference is inconsequential. (Figure 12). In relation to the gingival height, at the buccal side, the mean difference of both angulations was registered as a decrease of \(0.262\pm 0.246\) mm, which is statistically significant (\(p=0.001\); \(t\)-test). The gingival height means for the 30\({}^{\circ}\) provisional were \(0.519\pm 0.389\) mm and decreased to \(0.257\pm 0.210\) mm when there was a change to a provisional with greater angulation. Hence, the greater the emergence profile angle of the provisional, the greater the shift of gingival height towards the apical direction, thereby reducing the distance between the gingival margin and the margin of the preparation. \begin{table}

In lingual, the same effect occurs, and the mean difference in gum reduction is greater (from 0.390 \(\pm\) 0.279 mm) and also statistically significant (\(p\) = 0.001; \(t\)-test) (Table 2). \begin{table}
