Abstract

Aim: This study aimed to assess the accuracy of intraoral scanner (IOS) Medit i700 in scanning All-on-4 implant rehabilitation.
Subjects and methods: An edentulous mandibular model was designed with two straight anterior and two angulated posterior implants. The two test groups; were a short interimplant distance group (S) where the master model was fitted with two anterior and two posterior implants at the first premolar region. The second was the long interimplant distance group (L) two anterior and two posterior implants at the second premolar region. The model was scanned once with the extraoral scanner inEos X5, to obtain the reference scan and 10 times with the IOS, to obtain the test scans.
Results: Following statistical analysis it was evident that interimplant distance increase had no statistically significant influence on the accuracy of digital data obtained by Medit i700 wired.
Conclusion: Interimplant distance had no statistically significant effect on the accuracy.
