Abstract
Objective:To study the friction properties of the three kinds of metal,resin,ceramic dental restorative materials. Method:60 cases(90 teeth)from March 2010 to March 2013 in our hospital were randomly divided into three groups,namely the use of metal,resin and ceramic three different restorative materials for repair. Result:After six months of treatment,the success rate of metal group,resin and ceramic dental restorations group of patients were 93.3%,90.0%,93.3%,the success rate of the three groups of patients showed no significant difference(P>0.05). 1 year after treatment,three groups of patients with treatment success rates were compared and found that the three groups of patients with dental restorations success rates were 90.0%,86.7%,90.0%,the success rate of three groups of patients the treatment was no significant difference(P>0.05). After treatment, the treatment of one of three groups of patients for dental records in case of failure analysis and found that the metal group had one broken tooth,one tooth deformity,other failures occur teeth 1;resin group fall off teeth with a tooth broken teeth 2,a malformation of teeth;ceramic group:loose in a teeth, cracked a deformity 1.The failure of the repair of the three groups was no significant difference(P>0.05). Conclusion:The friction properties of the three kinds of metal,resin,ceramic dental restorative materials are no significant differences,in the application of the choice of materials should be specific circumstances.关键词
