Table 5.

Comparison of the fit of clasps with different materials in the same tooth position after testing.

Group	After circulation (μm)
Group	Clasp tip	P	Clasp arm	P	Occlusal rest	P
PEEK 46 (n = 10)	64.05 ± 29.50	0.035	64.47 ± 23.74	0.339	109.49 ± 50.03	0.055
Co–Cr 46 (n = 10)	104.51 ± 47.91	0.035	80.71 ± 46.55	0.339	182.59 ± 97.89	0.055
PEEK 44 (n = 10)	79.07 ± 25.79	0.194	66.28 ± 21.86	0.197	110.52 ± 43.44	0.349
Co–Cr 44 (n = 10)	100.28 ± 41.98	0.194	84.61 ± 37.35	0.197	147.62 ± 113.94	0.349

*After testing, the fit of the PEEK clasp tip at tooth position 46 was better than that of the Co–Cr alloy clasp.
