Objective:
The purpose of this study was to compare the clinical application and effect of two temporary restorations materials: composite and self-cured acrylic resin.
Methods:
153 composite temporary crowns (and bridges) placed in 44 patients and 144 self-cured acrylic resin temporary crowns (and bridges) placed in 49 patients were evaluated according to the California Dental Association's (CDA) criteria and questionnaire.
Results:
It showed that composite temporary crowns (and bridges) had better surface smoothness, marginal integrity and anatomic form than self-cured acrylic resin temporary crowns (and bridges). In the 49 patients with self-cured acrylic resin temporary crowns (and bridges), 67% and 88% of them complained of food impaction and mouth odor, while only 2% and 30% in the 44 patients with composite temporary crowns (and bridges) had the same complaint.
Conclusion:
Between the two temporary restoration materials, composite is better than self-cured acrylic resin.
