Statement of problem : Tooth wear is physiological phenomenon. Ninety-seven percent of
normal people have tooth wear and about 7% has pathologic teeth wear. If we know the amount
of tooth surface loss caused by pathologic tooth wear, we may restore it ideally.
Purpose : Recently, measurement of tooth wear by using 3D scan has been increasing. Therefore,
we need to know how accurate 3D scan is. Past accuracy test on 3D scan was about linear change,
but as we know that tooth wear is volume change. Thus, the purpose of this study is to know
how accurate 3D scan is.
Material and Methods : For accuracy test of 3D scanner, volume values measured by 3D scanner
and micro-balance were compared. For test I, preliminary, 3 ball samples and 3 circular cones
were made with pattern resin. For test II, 10 teeth shape rubber samples were used.
Results and Conclusion :
1. The result of the accuracy test on 3D scan with 3 ball samples and 3 circular cones made of
pattern resin has no significant difference(p<0.05).
2. The result of the accuracy test on 3D scan with 10 samples of tooth shape rubber has no significant
difference(p<0.05).
As a result, we may concluded the analysis of quantifying tooth wear used by 3D scan is useful
in the clinic.
