The results are presented using statistic descriptive analysis of frequency, for each questionnaire partition, in comparative tables and graphics. * **Respondents' demographic data the demographic information collected in the respondents' lot were age, sex and years of experience. The average age of the doctors in the study is 36 (\(\pm\)9.100) and 67.3% are females, for the technicians' lot the mean age is 28.6 (\(\pm\)8.59) and the sex repartition is 52.7% males (Table 1). Although the technicians' study lot is young, 40% of them have already fabricated over 20 fixed prosthetic restorations with implant support and 50.9% have made less than 9. A percent of 41.8% of the doctors have made more than 20 full-arch prosthetic rehabilitations and almost the same percentage have treated less than 10 cases. In order to test the correlation between the age of the respondent and the total number of prosthetic rehabilitations, the Kruskal-Wallis H test has been applied for the difference between the three groups of answers and the postdoc test for the difference between the two groups of answers. For the technicians' group significant results were obtained (Table 2). \begin{table}

Table 2: Test: Kruskal-Wallis H, \(p\) value = 0.000002 (general significant difference–between the three groups), postdoc tests (we are searching for differences between years of two groups): \(p\)-value = 0.000 (between 1. 1–9 restorations and 3. 20+ restorations). Concerning the treatment plan responsibility, 61.2% of the dental prosthodontic specialists claimed their leading role, and 28.5% affirmed that it is a shared responsibility with the dental technicians. The dental technicians' study group had a different opinion: half of them declared that the treatment plan is decided by both the dentist and technician, 29.1% declared that they are the leaders in the team and 5% that they manage the entire treatment plan.
