“…The lower fracture strength of Zr crowns on NRTi implants may have been due to using a 3 mm Ti abutment height compared to the 3.5 mm Ti abutment height used for RSTiZr implants. In addition, the above fracture strength values are higher than those recorded by Barbosa-Júnior et al, who noted the fracture strength of the Zr crowns on Ti implants to be 670 N. 38 Several factors 38 In addition, the fracture strength of screw-retained Zr crowns on Ti implants was found to be much higher (1978.6 N) by Donmez et al than the present study. 39 Donmez et al used a premolar for their sample preparations, similar to the current study; their specimens, however, were not fatigued with chewing simulation.…”

“…Implants were mounted in auto‐polymerizing polymethylmethacrylate (PMMA) cylinders (Fastray Custom Tray Material; Keystone Industries GmbH), whereas the implant platforms were placed above or at the level of the PMMA cylinders, according to the manufacturer's surgical protocol 38 (Table 1). Figure 3 depicts the steps involved in mounting implants in the PMMA cylinder.…”

PurposeThis in vitro study evaluated the fracture strength of screw‐retained zirconia crowns connected to zirconia (Zr) and titanium (Ti) implants after undergoing a simulation of 5 years of clinical use.Materials and methodsForty‐eight screw‐retained zirconia crowns were fabricated and assembled on four implant systems, with 12 in each group: (1) Zr implant (pure ceramic; Straumann AG) (PZr); (2) Zr implant (NobelPearl; Nobel Biocare) (NPZr); (3) Ti–Zr implant (Bone Level Roxolid; Straumann AG) (RSTiZr); (4) Ti implant (Conical Connection PMC; Nobel Biocare) (NRTi). Crowns were luted to their associated abutments using resin cement and then torqued to their assigned implants at the recommended torque value. Specimens were subjected to dynamic loading for 1,200,000 loading cycles. Fracture strength, measured in Newtons (N), was tested under static compression load using a universal testing machine at an angle of 30°. One‐way ANOVA and Tukey's multiple comparisons post hoc test were used to compare the mean fracture values between the groups at a significance level of 0.05.ResultsThe average fracture strengths for the RSTiZr and NRTi groups were 1207 ± 202 and 1073 ± 217 N, respectively, which was significantly (p < 0.0001) higher than the PZr and NPZr groups (712 ± 76 and 571.6 ± 167 N, respectively). However, no significant difference was found between the fracture strength value of RSTiZr and NRTi (p = 0.260) or PZr and NPZr (p = 0.256) groups.ConclusionsZirconia crowns connected to Zr implants have the potential to withstand the average physiological occlusal forces which occur in the anterior and premolar regions.

“…PEEK shows more mechanical effort than zirconia regardless of the crown material. Therefore, PEEK shows a not significant difference in fracture resistance, even though it is considered an alternative material to zirconia [ 18 , 19 ]. In contradiction with previous studies, Al-Zordk et al [ 10 ] have shown that the zirconia has a better fracture resistance than PEEK.…”

When implants are required in prosthodontics treatment, one of the most important decisions is the choice of the final crown and the type of connection to the implant through the abutment. Hybrid abutments are becoming a primary choice. They are projected and produced with materials whose properties guarantee the required mechanical features (including resistance) and take advantage of the hybrid abutment crown retention between screw and cement. However, a review of the mechanical resistance of the different abutment types and associated materials is still lacking. This review aimed to study the in vitro mechanical efficiency of the hybrid abutments used in oral rehabilitation. Methods: A systematic review was conducted using the PubMed, B-on, and Google Scholar databases according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Results: 75 articles were identified from all databases, and 33 were selected after abstract screening. Thus, 21 studies were included in the review after full-text reading. Among the materials used for crowns, lithium disilicate was, aesthetically, the primary choice for its aesthetic and moderate strength. On the other hand, zirconia showed the best fracture resistance. Regarding the different kinds of abutments, there is still some lack of knowledge about the best design. Conclusions: Within the limitations of this systematic review, we can conclude that hybrid pillars are an excellent choice for oral rehabilitation through implants, showing improved resistance when including materials such as zirconia and lithium disilicate.
