Purpose.
For a precise fit of multiple implant framework, having an accurate definitive cast is imperative.
The present study evaluated dimensional accuracy of master casts obtained using different impression trays and materials with open tray impression technique.
Materials and Methods.
A machined aluminum reference model with four parallel implant analogues was fabricated.
Forty implant level impressions were made.
Eight groups (n=5) were tested using impression materials (polyether and vinylsiloxanether) and four types of impression trays, two being custom (self-cure acrylic and light cure acrylic) and two being stock (plastic and metal).
The interimplant distances were measured on master casts using a coordinate measuring machine.
The collected data was compared with a standard reference model and was statistically analyzed using two-way ANOVA.
Results.
Statistically significant difference (p<0.05) was found between the two impression materials.
However, the difference seen was small (36 μm) irrespective of the tray type used.
No significant difference (p>0.05) was observed between varied stock and custom trays.
Conclusions.
The polyether impression material proved to be more accurate than vinylsiloxanether impression material.
The rigid nonperforated stock trays, both plastic and metal, could be an alternative for custom trays for multi-implant impressions when used with medium viscosity impression materials.
