Description
Summary:Objective: The purpose of this study was to assess the use of a verification jig to correct the position of dental implants in a 3D printed model and to compare its accuracy with dental casts obtained by conventional impression. Materials and methods: Three dental implants were installed in a partial dentate maxillary model and dental casts (n=10) were obtained by conventional and digital impressions. A verification jig was used to determine the implant position into the 3D printed model and its accuracy was compared with conventional cast. Results: Data were analyzed by within ANOVA and post hoc test at a significance level of p ≤ 0.05. A statistically higher measurement error (p≤ 0.05) was found for 3D printed models in comparison with conventional models, with a mean difference of 47µm. Conclusion: The use of verification jig for positioning dental implants in a 3D printed model.
