M. Degrange et al., BONDING OF LUTING MATERIALS FOR RESIN-BONDED BRIDGES - CLINICAL RELEVANCE OF IN-VITRO TESTS, Journal of dentistry, 22, 1994, pp. 190000028-190000032
A retrospective clinical study on 78 resin-bonded bridges placed betwe
en 1981 and 1992 was used to validate the wedge test in the assessment
of the bonding of resin-based luting material. According to the corre
lation obtained between the findings of the in vivo and the in vitro s
tudies, the wedge test may be considered to be predictive of the clini
cal performance of resin bonds. The life expectancy of resin-bonded br
idges bonded with the 4 META containing material tested appears to be
longer than that for bridges bonded with conventional resin cements.
