[Deflection and marginal leakage in cemented MOD inlays under loads parallel to the tooth axis].
Cemented inlays made of a soft and an extra hard gold casting alloy are subjected to load cycling with 50-200 N. The mesiodistal deflection is determined and marginal leakage is shown by dye penetration. Soft alloy inlays deflect significantly more, nearly 50% exhibit dye penetration caused by microleakage. On average, deflection does not occur with the extra hard alloy, dye penetration caused by microleakage takes place among 25% of the inlays only.
