Bond strength of Ti–5Cr based alloys to dental porcelain with Mo addition
Highlights ► Bond strength of Ti–5Cr alloys to porcelain with Mo addition have been studied. ► Bond strengths of Ti–5Cr–xMo alloys above lowest limit value in ISO 9693 standard. ► Ti–5Cr–9Mo had highest bond strength, higher than c.p. Ti, Ti–6Al–4V, Ti–5Cr alloys. ► Suitable addition of Mo will modify CTE of Ti–5Cr alloys.
Abstract Porcelain fused to metal crown (PFM) is widely used in dental restoration for its esthetics. Due to its excellent corrosion resistance, biocompatibility and mechanical properties, commercially pure titanium (c.p. Ti) and Ti–6Al–4V alloy have dramatically improved dental implants and prosthesis, despite the insufficient bond strength of titanium to porcelain. This study investigated the bond strength of new Ti–5Cr–xMo (x =1–11wt.%) alloys and low-fusing dental porcelain (Duceratin Plus, DeguDent Gmbh, Germany), and c.p. Ti and Ti–6Al–4V alloy were compared. The results show that Ti–5Cr–9Mo alloy has the highest bond strength (37.67MPa), a result that is higher than that of c.p. Ti (30.72MPa) and Ti–6Al–4V (30.01MPa).
