Effect and safety of titanium zirconium niobium tin alloy and nichrome for dental defects

doi:10.3969/j.issn.2095-4344.2015.25.015

Abstract

Abstract:

BACKGROUND: Titanium zirconium niobium tin alloy (Ti-Zr-NB-Sn alloy) has good tissue structure, mechanical properties, corrosion resistance and biocompatibility, which is an ideal dental material.
OBJECTIVE: To explore the efficacy and safety of Ti-Zr-NB-Sn alloy in dental restoration.
METHODS: A retrospective analysis was performed on clinical data of 87 cases of dental defects, including 43 males and 44 females, aged 22-41 years. Of the 87 cases, 43 cases were repaired with Ti-Zr-NB-Sn alloy as observation group, and the other 44 cases were treated with nichrome as control group. After 36 months of follow-up, the therapeutic efficacy, dental restoration conditions, dental prosthesis conditions and patient satisfaction were observed and compared.
RESULTS AND CONCLUSION: All the 87 patients were followed up for 36 months. After the follow-up, the total effective rate and patient satisfaction were higher in the observation group than the control group (P < 0.05). In the control group, there were four cases of swollen gums, four cases of bleeding gums, four cases of allergies, three cases of gum gray line, and six cases of mucosal pain; in the observation group, there was only one case of swollen gums, and the dental restoration was better in the observation group than the control group (P < 0.05). For the dental prosthesis, there were 10 cases of dental stent damage and 20 cases of dental stent loosening in the control group; and only one case of dental stent damage and one case of dental stent loosening in the observation, and the observation group was superior to the control group in the dental prosthesis (P < 0.05). Experimental findings suggest that Ti-Zr-NB-Sn alloy for repair of dental defects has good biocompatibility and security.
