To investigate the effect of 4 kinds of prosthodontic materials on masticatory and gingival function.
METHODS: RESULTS: There was no significant difference in curative effect in 4 groups(P>0.05). Before and
after treatment, there was no significant difference in mastication efficiency and
bite force in 4 groups(P>0.05). Before treatment, there was no significant difference in PLI, GI, SBI, gingival crevicular fluid weight, TNF-α,
IL-6, AST and ALP in gingival crevicular fluid in 4 groups(P>0.05). Compared with before treatment, PLI, GI and SBI in 4 groups were decreased
after treatment (P<0.05), and the decrease was in the order of
cobalt-
chromium alloy group≈nickel-
chromium alloy group<pure
titanium group<zirconia dioxide group. Before treatment, there was no significant difference in the weight of gingival crevicular fluid, TNF-α,
IL-6, AST and ALP in gingival crevicular fluid in 4 groups(P>0.05). The crevicular fluid weight, TNF-α,
IL-6, AST and ALP in gingival crevicular fluid were significantly increased(P<0.05), and the increase was in the order of
zirconia group<pure
titanium group<cobalt-
chromium alloy group≈nickel-
chromium alloy group. There was no significant difference in restoration integrity and color satisfaction in 4 groups(P>0.05), but there was significant difference in marginal fitness and sensitivity satisfaction in 4 groups(P<0.05).
CONCLUSIONS:
