Background: The clinical feasibility of implant restorations is heavily influenced by the accuracy of digital impressions. The purpose of this research is to compare the accuracy of conventional impressions with impressions made digitally using three-dimensional analysis. Materials and methods: Twenty implants in eight patients in the posterior region of the oral cavity formed the study sample. Two operators with good inter-examiner reliability performed the procedure. Conventional impression were taken using polyether impression material and stock trays. Digital impressions of the same patient were taken after 2-3 weeks. Outcomes assessed were total time taken, distance between scanbodies, angulation, rotation, and vertical shift were all evaluated as clinical outcomes. SPSS 23.0 version (SPSS Inc., Chicago, IL, USA) software was used for data analysis.
Results: In comparison to digital impressions, conventional impressions took longer time, which was statistically significant at p<0.001. In both impression approaches, the measurements of distance between scan bodies, angulation, and vertical shift were practically identical, which was not statistically significant.
Conclusion: Digital impressions outperformed conventional impressions during implant placement.
