Abstract [eng] The integration of digital intraoral scanners into dentistry has revolutionized the procedure and efficiency of dental impression-taking techniques. This thesis provides a comprehensive literature review of the development and use of digital intraoral scanners, highlighting their growing importance in modern dental practices. Following a theoretical review, the thesis presents a comparison and evaluation of two specific digital intraoral scanning devices, the Medit-I700 and the TRIOS 3Shape, to assess their accuracy in capturing the periodontium and the gingival margin with a focus on recession. An experimental approach was used to objectively measure and compare the accuracy of the two selected devices. The experiment involved the use of standardized procedures to simulate clinical dental impression taking, ensuring that the results are relevant and applicable to real- world settings. Ten probands with clinical present recession were examined. The results showed a significant difference in accuracy between the two scanners: The TRIOS 3Shape achieved an accuracy of 79.59%, while the Medit-I 700 had a slightly lower accuracy of 75.51% compared to manual measurements with a periodontal probe. The accuracy of both scanners is labeled as ,sufficient’. SPSS statistical analysis was employed to calculate statistical significant correlation between the data from the Intraoral devices and the manual reference measurement. Deviation occurred mostly in the measurement of recession less than 0,5mm. The results highlight the differences in performance between different intraoral scanners and suggest that the selection of such devices should be based on empirical evidence of their accuracy. This study contributes to the body of knowledge by providing empirical data on the accuracy of intraoral scanners to assist dental professionals in making informed decisions about which technology to incorporate into their practices. Further research is recommended to examine the long-term reliability of these devices and their impact on patient outcomes in different dental settings, while monitoring and evaluation of upcoming new technologies and improvements of current technologies are emphasized.
