Photoelastic Analysis of Fixed Partial Prosthesis Crown Height and Implant Length on Distribution of Stress in Two Dental Implant Systems

Table 4

Comparison of the study factors implant length and implant system relative to the crown height under axial loading in MPa.

Factor	Variables	Prosthetic crown
		8 mm	13 mm
Implant length	Short	33.4 ± 16.0; Aa	28.3 ± 12.2; Aa
	Long	24.6 ± 12.5; Ba	26.8 ± 13.4; Aa
System	Neodent	25.7 ± 11.4; Aa	31.5 ± 16.5; Ab
	Bicon	26.5 ± 13.0; Aa	29.4 ± 13.9; Aa

Note. Different uppercase letters represent statistically significant differences between implant length and between implant systems. Different lowercase letters represent differences between crown heights (Tukey’s test; ).
