Clinical Study on the Treatment of Wedge-shaped Defects with Resin Filling Device

Objective To investigate the application value of resin filling device in the repair of wedge-shaped defects. Methods 126 cases of wedge-shaped defect patients, a total of 178 teeth, were randomly divided into control group, repaired with ordinary resin filler, study group repaired with Kerr resin filler. Observe two groups of repair time, effect and shaping ability. Results Study group's filling time, shaping ability filling were significantly better than those of control group, P<0.05. There is statistically significant difference. And the work head has not sticking phenomenon of filling material. Conclusion Kerr resin filler can use of repairing wedge-shaped defect, has obviously clinal effect.
