Purpose:
To evaluate the clinical effect of modified casting post with zirconia crown in restoration of anterior teeth.
Methods:
A total of 45 anterior teeth (32 patients) were treated with modified gold-alloy post-cores with zirconia crowns. All roots were greatly tilted to the labial side. Marginal integrity, anatomic form, surface, color and the gingival situation after restorations were assessed at 6 and 12 months with the California Dental Association (CDA) quality assessment system.
Results:
The clinical outcome of 44 zirconia crowns achieved rank A (97.8%), while the gingival situation in one patient (2.2%) reached rank B.
Conclusions:
Modified gold-alloy post-core with zirconia crown contributes to the aesthetic effect of the anterior teeth which need to change the angle.
