As a result of increased education and communication, the field of orthodontic has
recently been expanded to include a greater number of adult treatment procedures. With
this increased demand for adult orthodontic treatment, a problem that frequently arises
is the placement of appliances of teeth restored with porcelain. But conventional
acid-etching is ineffective in the preparation of porcelain surface for mechanical retention
of orthodontic attachments. Also, it is possible to damage on porcelain.
The purpose of this study was to evaluate the effect of composite bonding materials
and the porcelain surface treatment methods on shear bond strength, and to observe the
porcelain fracture rates. To accomplish this purpose, this study was carried out with
feldsphatic porcelain, Ceram¥±. porcelain surface treatment methods were divided into
intact glazed porcelain which had not treatment and surface roughening. Surface
roughening by etching with Hydroluoric acid(HF), sandblasting with Microetcher ¥± and
compound treatment with etching and sandblasting. Bonding materials were Ortho-two
and Transbond. All porcelain specimens were applicated with porcelain primer.
1. In comparision according to porcelain surface treatment, surface roughening groups by
HF etching and sandblasting had higher shear bond than intact group. No significant
difference was found in Transbond group.
2. Ortho-two group had ¼Û higher shear bond strength than that of Transbond group in
HF etching and sandblasting.
3. E(Transbond + Intact) group had the lowest shear bond strength in all experimental
group. The bond strength was higher than clinically successful bond strength.
4. Non-treated group had very higher porcelain rates than treated group.
5. This study indicates that porcelain surface-roughening may not be necessary to
attachment of orthodontic brackets to porcelain surfaces.
