One Year Clinical Evaluation of E-max Press Crowns Retained with Fiber Reinforced Composite Post Versus E-max Press Endocrowns in Anterior Endodontically Treated Teeth (A Randomized Clinical Trial)

Abstract

Objective: The purpose of this study was to assess patient satisfaction, gross fracture and marginal adaptation of e.max press endocrowns versus e.max press crowns retained with Fiber reinforced composite post (FRCP) and core in upper anterior teeth. Material and methods: The present study included 24 patients seeking root canal treatment in anterior upper arch. The patients received root canal treatment (RCT) then they were randomly assigned into two groups (n=12). The first group received preparation for the IPS e.max crowns retained with FRCP and core and the second group received preparation for the IPS e.max endocrowns. Press technique was used for the fabrication of both restorations using IPS e.max press ingots. Marginal integrity and gross fracture were evaluated using USPHS criteria and a questionnaire was conducted to evaluate patient satisfaction. Data were analyzed using IBM SPSS Statistics for Windows, Version 23.0. Armonk, NY: IBM Corp. Results: There was no statistical significant difference regarding gross fracture of both groups after 12 months (p-value = 0.093, Effect size = 0.447), meanwhile; group 1 was statistically significantly higher than group 2 regarding marginal integrity (p-value = 0.037, Effect size = 0.513). Regarding patient satisfaction FRCP and core group showed statistical significant higher satisfaction than endocrown group (p-value = 0.047, Effect size = 0.447). Conclusion: E.max press endocrowns revealed successful performance similar to e.max press crowns retained with FRCP in terms of gross fracture, however better marginal adaptation and patient satisfaction was obtained with e.max press crowns retained with FRC post and core group.

Veneer crowns in anterior endodontically‐treated teeth: A case report with 1‐year follow‐up

“…The lack of data on endocrowns in anterior teeth and the varied results in different studies mean that an indication for endocrowns in anterior teeth cannot yet be stated 33 . Abou El‐Enein et al showed that e.max press endocrowns were as successful as e.max press crowns retained with fiber posts/composite resin cores (FRCP) in terms of gross fracture in anterior teeth, but higher marginal adaptation and patient satisfaction was obtained with crowns retained with FRCP which were used in the present case as well 34 …”

“…33 Abou El-Enein et al showed that e.max press endocrowns were as successful as e.max press crowns retained with fiber posts/composite resin cores (FRCP) in terms of gross fracture in anterior teeth, but higher marginal adaptation and patient satisfaction was obtained with crowns retained with FRCP which were used in the present case as well. 34 In recent years, zirconia ceramics have changed in microstructure and composition to achieve esthetically acceptable translucency without significant reduction in fracture resistance. Translucent zirconia is an esthetic material and can be used for many clinical situations including anterior and posterior monolithic crowns and fixed prostheses, veneers and ultrathin veneers.…”

Clinical and laboratorial performance of rehabilitation of endodontically treated teeth: A systematic review

“…For the endocrown, the results have shown to be promising for the posterior region, however, more investigations are needed to evaluate the biomechanical behavior in anterior teeth. 53 Only 1 clinical study 49 included in this systematic review evaluated the use of endocrown in anterior teeth, which did not differ in fracture when compared with a full crown, although the period of analysis has been only 1 year and needs long-term investigations. In any case, regardless of the incidence of forces, for the ETT rehabilitation, the professional must seek to preserve as much of the remaining structure as possible, since studies suggest that success is more related to the quantity and quality of the coronal remnant.…”
