Abstract
This study compared the accuracy of an abutment-framework (A-F) taken with open tray impression technique combining cementon crown abutments, a metal framework and resin cement to closed tray and resin-splinted open tray impression techniques for the 3-implant definitive casts. The effect of angulation on the accuracy of these 3 techniques was also evaluated.
Three definitive casts, each with 3 linearly positioned implant analogs at relative angulations 0, 30, and 40 degrees, were fabricated with passively fitted corresponding reference frameworks. Ten impressions were made and poured, using each of the 3 techniques on each of the 3 definitive casts. To record the vertical gap between reference frameworks and analogs in duplicate casts, a light microscope with image processing was used. Data were analyzed by two-way analysis of variance and the Tukey test.
The open tray techniques showed significantly smaller vertical gaps compare to closed tray technique (
The accuracy of the A-F impression technique was superior to that of conventional techniques, and was not affected by the angulation of the implants.

<abstract><sec><title>PURPOSE</title>
<p>This study compared the accuracy of an abutment-framework (A-F) taken with open tray impression technique combining cementon crown abutments, a metal framework and resin cement to closed tray and resin-splinted open tray impression techniques for the 3-implant definitive casts. The effect of angulation on the accuracy of these 3 techniques was also evaluated.</p>
</sec>
<sec><title>MATERIAL AND METHODS</title>
<p>Three definitive casts, each with 3 linearly positioned implant analogs at relative angulations 0, 30, and 40 degrees, were fabricated with passively fitted corresponding reference frameworks. Ten impressions were made and poured, using each of the 3 techniques on each of the 3 definitive casts. To record the vertical gap between reference frameworks and analogs in duplicate casts, a light microscope with image processing was used. Data were analyzed by two-way analysis of variance and the Tukey test.</p>
</sec>
<sec><title>RESULTS</title>
<p>The open tray techniques showed significantly smaller vertical gaps compare to closed tray technique (<italic>P</italic>
< .05). The closed tray and the resin-splinted open tray technique showed significantly different vertical gaps according to the angulation of implant (<italic>P</italic>
< .05), but the A-F impression technique did not (<italic>P</italic>
> .05).</p>
</sec>
<sec><title>CONCLUSION</title>
<p>The accuracy of the A-F impression technique was superior to that of conventional techniques, and was not affected by the angulation of the implants.</p>

<caption><p>Impression procedures performed on the definitive cast and the soft tissue cast. A: Closed tray impression copings on the 0 degree definitive cast, B: Resin splint of open tray impression copings was sectioned on the 30 degrees definitive cast, C: A-F impression. Soft tissue cast and abutments were connected to the 30 degrees definitive cast, D: A-F impression. Assembly of abutments and metal framework on the 40 degrees definitive cast.</p>
