Clinical study of zirconia all-ceramic crown and zirconia crown in molar fix prothesis
Abstract：Objective To compare the repairing effects between the zirconia all-ceramic crown bridge and zirconia bridge in aesthetics restoration of molars .Methods Thirty-six patients were restorated with the all-ceramic crown bridge(19 patients 66 molars) and zirconia ( bridge 17 patients 60 molars), followed up for 1 ~3 years, checked and appraised the marginal adaptation ,form,colour of the crowns ,the gingiva and crown fracture by one doc-tor.Results There was no statistically difference in the effects between the two kinds of restorations .Conclusion The two kinds of restoration can meet clinical needs in the marginal adaptation ,aesthetics and the flexural strength . The zirconia bridge is better in patients with shorter occlusogingival distance .
