Replacement of existing fillings with stress-reduced direct composite restorations on vital and devital molar teeth.
The design of the new restorations was completed in an attempt to protect the residual tooth structure from both polymerization shrinkage and occlusal loading. Metal posts were partially removed on the first molar tooth. The skeleton of the restoration was build up first and followed by the placement of polyethylene fibers as close as possible to the residual tooth structure. The strategic fiber lay down onto the cavity walls allowed to bridge the cracks on dentin and mimic the shock absorbing effect of the dentin-enamel complex. No post, no traditional dental crowns are required to predictably restore structurally compromised teeth. The final fiber-reinforced restorations mimic the functional and aesthetic characteristics of the natural dentition.
