Aim.
To evaluate the influence of different manufacturing methods of single implant-supported metallic crowns on the internal and external marginal fit through computed microtomography.
Methods.
Forty external hexagon implants were divided into 4 groups (n=8), according to the manufacturing method: GC, conventional casting; GI, induction casting; GP, plasma casting; and GCAD, CAD/CAM machining.
The crowns were attached to the implants with insertion torque of 30 N·cm.
The external (vertical and horizontal) marginal fit and internal fit were assessed through computed microtomography.
Internal and external marginal fit data (μm) were submitted to a one-way ANOVA and Tukey’s test (α=.05).
Qualitative evaluation of the images was conducted by using micro-CT.
Results.
The statistical analysis revealed no significant difference between the groups for vertical misfit (P=0.721).
There was no significant difference (P>0.05) for the internal and horizontal marginal misfit in the groups GC, GI, and GP, but it was found for the group GCAD (P≤0.05).
Qualitative analysis revealed that most of the samples of cast groups exhibited crowns underextension while the group GCAD showed overextension.
Conclusions.
The manufacturing method of the crowns influenced the accuracy of marginal fit between the prosthesis and implant.
The best results were found for the crowns fabricated through CAD/CAM machining.
