## 3 Results  
Regarding the functional criteria, no deviations from the reference range were registered in any of the study groups for both measurements. The measurement results for the biological criteria were as follows:  
With regard to the plaque retentive index, it can be concluded that in the supra-implant restorations, a combination of an individualized titanium base and monolithic lithium disilicate crown (Group B) exhibits the best behavior (the absence of plaque around the restorations). This conclusion was valid for both observation periods. \begin{table}

Figure 4: Measurement of the bone loss level. The highest amount of plaque was observed in Group C.  
In Groups A and C, the plaque increased during the observation period. This increase was more noticeable in Group C. The value of the index reached 0.56 in one year, and the increase was statistically significant (_p = 0.01_). In Group A, the observed increase from 0.17 to 0.22 was characterized by static insignificance (_p = 0.08_) (Table 5). Group A showed the worst performance in terms of bleeding on the oral side at the 1-year follow-up. The best general mean values of the bleeding indicator were observed in Group B, where initially, there was no bleeding in the second week, while at 1 year, the value remained relatively low at 0.22 on both the vestibular and oral sides. On both sides--vestibular and oral--there were statistically significant differences in the second week due to the increased values of the bleeding indicator in Group A. The differences became insignificant between the groups after one year of observations. On the vestibular side, _p = 0.39_, while on the oral side, _p = 0.35_ (Table 6). Group B had the lowest periodontal pocket depth (PPD) values throughout the study period, followed by Group C. The highest values were reported in the prosthetic restorations used in Group A, increasing by almost two times over a period of 1 year. In Group C, there was a statistically insignificant decrease in the pocket depth value (_p = 0.46_). In Groups A and B, there were increases in the observed period, as shown in the table. In both cases, these were statistically significant, with _p = 0.03_ and _p = 0.00_ (Table 7). Despite the observed differences in the dynamic development of the three groups, the patients in Group B maintained the lowest pocket depth values during probing compared to the other groups. It is also important to note that statistically significant differences were observed when the three groups were compared in the second week and after one year \begin{table}
