[Resistance recovery of prepared teeth obturated with different materials]

We have compared the endurance recuperation to the fracture of class II cavities, OM and MOD, filled with amalgam or composite resin. The composite resin recuperates the tooth endurance in the MOD cavities and in the OM cavities. The teeth with small OM cavities filled with amalgam recuperate their endurance to the original compression but the teeth with MOD cavities filled with this material don't recuperate it.
