Endocrowns in Anterior Teeth: Effect of Cementation Protocols and Restorative Materials on the Clinical Performance of the Restorations

Overview

Rehabilitation of anterior endodontically treated teeth with significant coronal damage has been problematic. Adopting endocrown design to treat teeth with this condition is still under investigation. To address this issue, the USPHS criteria were adopted to assess the anterior endocrown restorations manufactured using various ceramic materials and cemented with different protocols.

40 participants with anterior endodontically treated maxillary central incisors were enrolled to restore their teeth with esthetic restorations Patients were divided into two groups, zirconia and e-max groups. Each group was, further subdivided into two groups following the cementation protocol. Patients were evaluated immediately (baseline) and at. The clinical marginal accuracy measurements were carried out for all groups at baseline, 3, 6, 9, 12, and 18 months and evaluated by 3 investigators using Modified (USPHS). The patients' satisfaction and potential postoperative discomfort were also assessed and recorded during the same periods. All qualitative data were displayed as frequency (N) and Percentages (%). The chi-square test was utilized for qualitative data comparisons. Results: As to marginal integrity and patient satisfaction, no significant difference were revealed regarding all scores at different intervals as P\>0.05. Conclusions: According to the findings of this study, ceramic endocrowns offer a promising restorative solution for the rehabilitation of anterior endodontically treated teeth. Additionally, regardless of the presence of the MDP monomer in its composition, using adhesive resin cement achieved highly successful results when used with MDP-based ceramic primers.
