“…Clinical results from long-term studies up to 17 years with crowns cemented on composite core build-ups have failed to demonstrate the merits of a metal post on the tooth survival in the presence of adequate ferrule effect [14,15]. The introduction and application of fiber reinforced composite posts has changed the view on the subject.…”

Purpose: The purpose of this in vitro study was to compare the effect of endocrowns and glass fiber postretained crowns on the fracture resistance of endodontically treated maxillary premolars made of different ceramics materials. Materials and Methods:Thirty sound maxillary premolars were endodontically treated. They were randomly assigned into 3 groups (n=10), in which, teeth were prepared to receive all-ceramic restorations. GP: fiber post and resin core and ferrule with all-ceramic (IPS E-max CAD, Ivoclar-Vivadent) conventional crown. GE: Endocrown with butt joint finish line design made of (IPS E-max CAD, Ivoclar-Vivadent). GC: Endocrown with butt joint finish line design made of hybrid nanoceramic (CERASMART, GC Dental, USA). The lithium disilicate (IPS E-max press, Ivoclar-Vivadent) and hybrid nanoceramic (CERASMART, GC Dental, USA) all-ceramic restorations were made by CAD/CAM system (CEREC MC XL SW 4.0) and adhesively cemented with dual-cure resin cement (BisCem Bisco, Inc, USA). Specimens were mounted in a universal testing machine (Model 3345; Instron Industrial Products, Norwood, MA, USA). Each specimen was loaded to failure at a crosshead speed of 5.0 mm / min. Mode of failure was also examined. Data were analyzed using one way analysis of variance (ANOVA) and Tukey's post hoc significance difference tests. Differences were considered significant at P<0.05. Results:One way ANOVA test showed that group (GC) recorded statistically significant (p<0.05) highest mean value (1522.64 N) followed by group (GP) (1301.34 N) then group (GE) (725.73 N). Group (GE) recorded the lowest statistically significant (p<0.05) mean value (725.73±137.89 N). Pair-wise Tukey's post-hoc test showed nonsignificant (P>0.05) difference between GP and GC groups. Conclusions:Within the limitations of this study, all fracture resistance loads obtained in this study were far beyond the maximum masticatory forces and the presence of hybrid nanoceramic increased the fracture resistance of endodontically treated maxillary premolars restored with endocrown than those restored with lithium disilicate endocrowns, in failure mode hybrid nanoceramic showed favorable fracture pattern than lithium disilicate.

“…Providing a crown with adequate ferrule has more influence on the fracture resistance of dowel-restored teeth than factors related to post and core materials and designs (134,169). D'Arcangelo et al (170,171) suggested the use of fiber posts when veneer restorations were used to restore endodontically treated teeth because they found that fiber posts increased the fracture resistance of endodontically treated teeth prepared for or restored with composite or porcelain veneers.…”

“…Further factors for clinical success are marginal adaptation of the veneer restoration, tooth preparation design, functional and morphological condition of the abutment tooth [8,9]. Veneer restorations appear to be a good choice also for endodontically treated teeth [10,11]. An optimal bond is obtained if the preparation is located completely in enamel, if correct surface treatment procedures are carried out, and if a suitable composite luting agent is selected.…”

“…According to previous authors, these shortcomings had no direct impact on the success of porcelain veneers in the medium term, although their influence on the overall clinical performance in the long term is still unknown [8]. Porcelain veneers adhesive luting could be performed employing both dualcuring and light-curing cements [7,8,[11][12][13]. Dual-curing materials are advantaged by their self-curing component, which favors the conversion even in the presence of scarce radiant energy, but have the disadvantages of being considerably fluid and requiring a mixture of two elements, arising in the probable formation of porosities or voids and incorporation of bubbles; moreover, their handling times are limited.…”

The purpose of this study was to evaluate the clinical performance of laminate porcelain veneers bonded with a light-cured composite. Thirty patients were restored with 119 porcelain laminate veneers. The veneers were studied for an observation time of 7 years. Marginal adaptation, marginal discoloration, secondary caries, color match, and anatomic form were clinically examined following modified United States Public Health Service (USPHS) criteria. Each restoration was also examined for cracks, fractures, and debonding. Pulp vitality was verified. In addition, plaque and gingival indexes and increase in gingival recession were recorded. Survival rate evaluating absolute failures and success rate describing relative failures were statistically determined, using both restoration and patient-related analyses. On the basis of the criteria used, most of the veneers rated Alfa. After 7 years, the results of the clinical investigation regarding marginal adaptation and marginal discoloration revealed only 2.5% and 4.2% Bravo ratings, respectively, among the 119 initially placed veneers. Using the restoration as the statistical unit, the survival rate was 97.5%, with a high estimated success probability of 0.843 after 7 years. Using the patient as the statistical unit, the survival rate was 90.0% and the estimated success probability after 7 years was 0.824. Gingival response to the veneers was all in the satisfactory range. Porcelain laminate veneers offer a predictable and successful treatment modality giving a maximum preservation of sound tooth. The preparation, cementation, and finishing procedures adopted are considered key factors for the long-term success and aesthetical result of the veneer restorations.
