Abstract
To overcome the failure of adhesive bridge due to release of the adhesive bond cement between teeth and metal,
preparation modification was performed with a pin hole in the teeth cingulum. This study aimed to determine the effect
of thread on a pin hole to shear strength adhesion of adhesive bridge. Forty maxillary incisors were prepared at their
palatinal surfaces 0.3 mm thick, and were divided into four treatments (threaded hole+threaded pin, threaded holes+
non-threaded pin, non-threaded holes+threaded pin, non-threaded holes+non-threaded pin). Casted-plates made from
nickel chromium alloy were cemented to the palatal surface of the tooth with adhesive cement (Panavia TMF 2.0), and
then adhesion shear strength tested. The test and evaluation of the residual cement on the surface were performed in
Laboratory Metallurgy, Department of Engineering ITB. Data were analyzed by one-way ANOVA test (p=0.05).
Adhesion shear strength of plate with threaded holes+threaded pin has the highest retention. Residual cement on
threaded hole+threaded pin plates similar to threaded hole+non-threaded pin, but more than any other groups. the
conclusions were, the adhesion shear strength depends on the design of pin hole. The wider surface of cement
remaining on the plates, the greater adhesion shear strength.
