Abstract
The purpose of this study was to investigate the effect that three resin indexing
materials had on the distortion of split cast in the procedures of solder indexing and
block fabrication.
The specimen had two cylinders and connecting bar. Two cylinders were a reference
cylinder and a test cylinder that were machined precisely and placed on metal base. The
total of specimens wee 30 and they were divided into 3 groups according to the resin
indexing materials : Acrylic solder , G-C Pattern resin ,
Z-100 .
The relative coordinates (X, Y, Z) of centroids of both cylinders were measured by
using 3-D coor dinates measuring machine.
The value of indexing distortion was obtained after application of indexing material,
and the value of the block distortion was obtained after fabrication of soldering block,
and the value of total distortion was a value sum of indexing distortion and block
distortion. Intercentroidal linear distortion({{{{ SQRT {X'^2 + Y'^2 +Z'^2 }- SQRT {X^2 + Y^2 +Z^2}
}}
}})
and global distortion {{{{rm SQRT {(X'-X)^2 +(Y'-Y^)2 +(Z'-Z^)2}
}}
}}
were calculated from data of coordinates of centroids at each mea

r
ing stages.
The results of this study were as belows ;
1. The intercentroidal distance between the split casts was reduced by indexing
distortion and increased by block distortion.
2. The indexing global distortion between the split casts was smaller than block global
distortion.
3. The intercentoidal linear distortion and the global distortion were no significant
difference between indexing materials.
