Abstract
Purpose. is investigate the influence of surface treatment and thermocycling on porcelain bonding to two forms of titanium.
Material and methods. 40 specimens (25x3x0.5 mm) were machined by using wire-cut electric discharge machining (WEDM) technology and assigned into 2 groups as per the material form (n=20): Cp Ti grade 2 and Ti-6Al-4V alloy. The specimens were further assigned into 2 subgroups (n=10) as per the tested surface treatment: airborne-particle abrasion and hydrochloric acid treatment. Ni-Cr alloy specimens (n=10) were provided as a control. Ultra-low fusing porcelain was applied at the center of the treated titanium specimens. Half of the titanium specimens in each subgroup were subjected to 5000 cycles of thermocycling in water (n=5). Flexural bond strength measurements for all specimens were determined by using a universal testing machine . A representative specimen was observed by using a scanning electron microscope . Data were analyzed statistically by using 2-way ANOVA and the Student-Newman-Keuls (SNK) post hoc tests (α=.05).
Results. No statistically significant difference in bond strength was found between both forms of titanium and the control group (P=.805). In addition, the effect of surface treatment and thermocycling on porcelain bonding to both forms of titanium was not statistically significant (P=.481 and .864).
Conclusions. The bond strength of both forms of titanium (Cp Ti grade 2 and Ti-6Al-4V alloy) to ultra-low fusing porcelain was comparable to that of the control group. Both airborne-particle abrasion and hydrochloric acid treatment improved porcelain bonding to both forms of titanium.
