Uniaxial compression tests were carried out on both of the MWCNT blocks (cut into round pieces of 3 mm in diameter and 1 mm in height), poly(ethylene terephthalate) (PET)-fiber-reinforced collagen sheets (MedGEL, MedGEL, Kyoto, Japan), and rat femoral bones(n = 5). Bones dissected from femoral shafts of 10-week-old male Wistar rats (SLC, Shizuoka, Japan) were cut into cylinders of 3 mm in diameter and 1 mm in height. Compressive strength was measured in a direction perpendicular to the bottom surface of each cylinder using an Autograph AGS-H (Shimadzu Co, Ltd, Kyoto, Japan) at compression speed of 1 mm/min.

Each specimen was subjected to a three-point bending test using a universal testing machine (Autograph AGS-H, Shimadzu, Kyoto, Japan) with a 20 mm support span and a crosshead velocity of 1.0 mm/min after one week of storage in distilled water at 37ºC (n=10 for each group). The flexural strength was calculated based on the load at a fracture point or the maximum load in the absence of a fracture, and a 0.02% yield strength was defined by the tolerance of the stress-strain curve and the 0.02% offset line by a software operation (TRAPEZIUM X, Shimadzu). The flexural strength and elastic modulus were calculated using the following formulas: Flexural strength=3PL/2bh² (1), Elastic modulus=FL³/4dbh³
(2), where P is the maximum load (N), L is the support span (mm), and b and h are the specimen width and thickness (mm), respectively. Furthermore, F is the load (N) at the proportionate point on the load-deformation curve, and d is the deformation (mm) at load F.

In this study, the specimens were subjected to threepoint bending test to determine the maximum flexural strength of the post and core systems using a universal testing machine (Autograph AGS-H, Shimadzu, Kyoto, Japan). The shape of the two supports and the loading anvil of the testing machine was a semicircle with a diameter of 2.0 mm. The supports were spaced 10 mm apart. The force was applied perpendicularly at the center between the supports at a crosshead speed of 1.0 mm/min and the flexural strength was evaluated.

Uniaxial compression tests were carried out on both the UDPHAp and IP-CHA (n = 6). Compressive and tensile strength were loaded against the bottom surface of the cylindrical scaffolds in a perpendicular direction (parallel to the orientation for the UDPHAp) by the Autograph AGS-H (Shimadzu Co, Ltd., Kyoto, Japan) at a compression speed of 1 mm/min.

The TBS was measured using a universal testing machine (Autograph AGS-H, Shimadzu, Kyoto, Japan) at a crosshead speed of 1.0 mm/min (Fig. 1). The TBS value was calculated using software (TRAPEZIUM X, Shimadzu) based on the following formula: s=F t /A, where s is the TBS, Ft is the maximum load at failure, and A is the adhesive area. The de-bonded area was examined with both a binocular stereomicroscope (SZH 10, Olympus, Tokyo, Japan) at 40× magnification and a SEM (S-4500). The failure types were classified as: 1) adhesive, 2) cohesive within PEEK, 3) cohesive within resin cement, or 4) mixed.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
