[Cause of food impaction after fixed denture restoration and therapeutic effect of gap expansion and resin repair].
OBJECTIVE
To discuss the cause of food impaction after fixed denture restoration and to analyze the therapeutic effect of gap expansion and resin repair.


METHODS
A total of 100 patients who suffered from food impaction after they received fixed partial denture were chosen. The cause of food impaction was analyzed. Treatment methods were applied on the basis of different causes. Gap expansion and resin repair were implemented to remove food impaction caused by the poor contact of the denture with healthy adjacent teeth.


RESULTS
The poor contact between fixed denture and healthy adjacent teeth was the major cause of food impaction (70%) . The effective rate of treatment among patients who received fixed partial denture but suffered from food impaction after 3 years was 100%.


CONCLUSIONS
The proposed method can be applied to treat food impaction caused by the poor contact of denture with healthy adjacent teeth.
