Mechanical behavior of nano-hybrid composite in comparison to lithium disilicate as posterior cement-retained implant-supported crowns restoring different abutments

Effect of adhesive system, resin cement, heat-pressing technique, and thermomechanical aging on the adhesion between titanium base and a high-performance polymer

“…However, for cyclic loading, the number of cycles and the force exceeded 1 200 000 cycles with a 49-N or 98-N force, as are commonly applied. [28][29][30] Even though relatively higher loads were applied in the present study, the fact that no failures occurred during cyclic loading may indicate the clinical suitability of all techniques tested.…”

“…The specimen and test design were based on previous studies. [27][28][29][30] After thermomechanical aging, the specimens were evaluated under ×10 magnification by the same operator (D.G.) to check for any micromovement or fracture.…”

Effect of restoration material on marginal bone resorption around modified anatomic zirconia dental implants: A randomised controlled trial

“…Additionally, restorative materials with lower modulus of elasticity have greater ability to absorb occlusal forces and therefore transmit lower forces and stress to the bone [ 32 ]. Elsayed et al suggested to use a solid abutment, e.g., zirconia abutment with a composite resin crown restoration [ 33 ]. They found that this combination showed the most favorable and the best tested situation withstanding normal occlusal forces [ 33 ].…”

Composite resin restorations bonded to zirconia abutments were found to possess damping behavior similar to normal teeth [ 34 ].…”

Wear resistance of CAD/CAM one‐piece screw‐retained hybrid‐abutment‐crowns made from different restorative materials

“…3,4 All-ceramic abutments and crowns enhanced the esthetic outcome considerably and showed promising mechanical properties in several studies. [7][8][9][10][11] Computer-aided design and computer-aided manufacture technology (CAD/CAM) has facilitated the manufacturing of all-ceramic restorations, speeding up the process in addition to simplifying it. 12 In addition, CAD/CAM technology enabled the production of one-piece screw-retained implant-supported crowns, 8 eliminating problems related to cementation and visible margins of the crowns, which contributes to better esthetics, retrievability and is helpful in cases with limited interocclusal space.…”
