Abstract
Objective To study the clinical application prospect of the monolithic zirconia crown by means of comparing clinical esthetic effects of two kinds of zirconia crowns.Methods This survey involved 87 individuals receiving anterior and premolar teeth esthetic fixed dental prostheses treatment.Totally 42 participants were allocated to experimental group which used TRIOS intraoral scanner to receive a 3D digital model of corresponding positions,and then "TT"zirconia was profiled to produce monolithic zirconia crowns.Totally 45 participants were allocated to control group,in which silicon rubber impression was used to produce traditional veneered zirconia crowns.The satisfaction degree of these patients with their restorations was scored five aspects.Three prosthodontists assessed the esthetic appearance of both groups through the scoring system modified by Ryge standard.After the treatment,the clinical effects were assessed by the same prosthodontist through the modified USPHS standard.Results In the satisfaction survey,patients in experimental group achieved lower satisfaction degree than in control group in the aspect of color distribution and individual characteristics (P ＜ 0.05).The assessment of the esthetic property of three prosthodontists showed no significant difference(P ＞ 0.05)between experimental group(1.838 ± 0.169)and control group(1.631 ± 0.149).According to the followup evaluation,experimental group showed great advantage over control group in the aspect of marginal adaptation,gingival reaction and integrity of restorations (P ＜ 0.05).Conclusion Monolithic zirconia crowns display excellent esthetic property in anterior and premolar teeth,and achieve great clinical application prospect.关键词
