Zirconium dioxide ceramic crown in repair of upper and lower anterior teeth and its oral aesthetics

Objective To explore the clinical effect and oral aesthetics of zirconium dioxide ceramic crown in repair of upper and lower anterior teeth. Methods 68 patients undertaking the repaire of upper and lower anterior teeth at our department from March, 2013 to May, 2014 were selected and divided into a control group (n=32) and a research group (n=36). The control group were repaired with common ceramic crown and the research group zirconium dioxide ceramic crown. After 2 years’ follow-up, the successful repair rate, gingival condition, edge coloring, the degree of adaptability and damage of adjacent teeth were compared between these two groups. Results 128 teeth were graded A and 6 B in edge coloring in the research group and 86 A, 20 B, and 12 C in the control group, with statistical differences (P<0.05). The gingival condition and the degree of adaptability and damage of adjacent teeth were significantly better in the research group than in the control group (P<0.05) . Conclusions Zirconium dioxide ceramic crown in the repair of upper and lower anterior teeth is significantly better in successful repair rate and repair effect than common ceramic crown. It not only has an important application value for the restoration of oral aesthetics, but also bring more convenience to the patients as well as periodontal health.
