Ai. Abdalla et Cl. Davidson, COMPARISON OF THE MARGINAL AND AXIAL WALL INTEGRITY OF INVIVO AND INVITRO MADE ADHESIVE CLASS-V RESTORATIONS, Journal of oral rehabilitation, 20(3), 1993, pp. 257-269
For several different procedures and material combinations adhesive Cl
ass V composite restorations were made under clinical and under labora
tory conditions. Marginal discrepancy and gap formation at the floor o
f the cavity was recorded by way of SEM on replicas. Only weak correla
tion could be demonstrated between results obtained from in vivo and i
n vitro placed restorations. In general the hydrophobic resinous bondi
ng systems performed better under laboratory conditions while the hydr
ophillic glass ionomer lining led to a better marginal integrity under
clinical circumstances.
