“…Different reinforcement types for the two materials make them have different mechanical properties as TRINIA is glass fiber reinforced polymer while BioHPP is ceramic particles reinforced polymer. The modulus of elasticity of TRINIA and BioHPP are comparable to human dentin and bone respectively that may lead to uniform stress distribution and reduce the strain developed on the peripheral bone [23,37,38]. Composite resin veneering was used for improved shock absorption and damping behavior compared with ceramic materials.…”

INTRODUCTION:Evaluation of strain developed around implants is playing an important role in the success of osseointegration of implants. Among the factors that affect the strain development, we can include the superstructure material. OBJECTIVE: The present study used strain gauge to perform an in-vitro evaluation of strain development around dental implants after using two different CAD-CAM reinforced polymers as superstructure materials. MTERIALS AND METHODS: Sixteen polyurethane test blocks were divided into two groups according to the superstructure material, biocompatible high-performance polymer (BioHPP) and reinforced nano-hybrid polymer with multi-layered glass fiber (TRINIA). Superstructures were fabricated with the same design using computerized aiding design then milling from CAD-CAM blocks. Strain gauges measured microstrain values. A universal testing machine was used to apply static load from 0 to 100 N in axial and 45-degree oblique directions on the superstructure. Then, the microstrain values were measured using a strain meter. Comparisons between the two groups were done using t-test, while comparisons between the buccal and palatal areas around the implant were done using paired t-test. Three-way ANOVA was performed to assess factors affecting strain development around implants (P=.05). RESULTS:The microstrain developed around TRINIA was significantly lower than BioHPP (p <.001).The oblique load leads to higher strain development compared to the axial load. Regarding the oblique load, the strain values were higher in buccal area than the palatal one. CONCLUSION: Strain development around dental implants is influenced by the superstructure material. The oblique occlusal load caused higher microstrain than the axial occlusal load.

Background Calcium silicate-based sealer has favorable properties for root canal filling, including hydroxyapatite formation during the setting process. However, this process can cause difficulty during post space preparation when the sealer is set. Additionally, the remaining sealer could interfere with the bond strength of fiber post to root canal dentin. The different adhesive strategies and fiber post cementation time may affect the bond strength of the fiber post. Thus, the objective of this study was to evaluate the effect of etching modes of Scotchbond™ Universal Plus adhesive and post cementation time on the push-out bond strength of a fiber post cemented in root canals obturated with calcium silicate-based sealer. Methods Fifty-four teeth were randomly allocated to 6 groups (n = 9) based on etching modes: self-etch (SE) or etch-and-rinse (ER); post space preparation and cementation time: immediate (Im) or 7-day delayed (De): Im-Im, Im-De, and De-De. The root canals were obturated with calcium silicate-based sealer and the post space preparation was performed. The fiber post was cemented using RelyX™ Universal resin cement according to each group’s design. For the push-out bond strength test, 1-mm slices of the coronal, middle, and apical regions were tested using a universal testing machine. The failure mode analysis was determined using a stereomicroscope. The data was analyzed with three-way analysis of variance. Results No negative effects of etching modes, post space preparation or cementation time on push-out bond strength were detected (p > 0.05). Additionally, the root canal region also did not significantly affect the bond strength (p > 0.05). Conclusion No significant differences were observed between the etching modes, post space preparation and cementation time and among root canal regions. Clinical relevance The different etching modes of adhesive and post cementation time did not affect the bond strength of fiber post in calcium silicate filled-root canal.
