Abstract
Objective To observe and compare the clinical effect of CAD/CAM all-ceramic crowns with cobalt-chromium alloy porcelain crowns in the restoration of anterior teeth.Methods Eighty-nine anterior teeth were restored with zirconia all-ceramic crowns,and 67 anterior teeth were restored with conventional cobalt-chromium alloy porcelain crowns.One year after the restoration,the marginal discoloration,change of marginal fit,color,caries around the crown,collapse porcelain and periodontal tissue heath of the two crowns were compared.Results The differences of the marginal discoloration,change of marginal fit,color,periodontal tissue heath between zirconia all-ceramic crowns and cobaltchromium alloy porcelain crowns was statistically significant (P ＜ 0.1).The clinical effect of all-ceramic crowns was better than cobalt-chromium alloy porcelain crowns.Conclusion The clinical effect of CAD/CAM all-ceramic crowns was favourable in restoring anterior teeth.关键词
