description Complete dentures are made of acrylic material, though its main downside is the midline fracture. Throughout years, many reinforcement methods were advocated to repair the midline fracture. Hence, this study aims to evaluated different reinforcement methods used to overcome fracture problem. And to asses which technique of repair can provide better strength for complete denture repair. Methods: The present study included a sample of 50 identical maxillary complete dentures. The midline fracture was reproduced on center of the dentures, then repaired with five different reinforcement methods (n = 10). The reinforcements were placed 1 mm away from the tissue surface. First method; was repaired without reinforcing materials (as a control group). Second method; repaired with 3% of Magnesium oxide nanoparticles impregnated into auto-polymerizing resin. Third method; dentures reinforced with orthodontic wire soldered as meshwork. Forth method; reinforcement with the fiber, fifth method; reinforcement with the chrome metal meshwork. The fracture strength of maxillary complete denture was tested using universal testing machine and load was applied to the tissue surface of the denture with a 10-mm diameter ball at a crosshead speed of 5 mm/min. The results were analyzed using stat graph version 5.1, one-way ANOVA (p<0.05). Results: The denture fracture resistance was significantly decreased when denture was repaired with 3% of magnesium oxide nanoparticles compared with control group, (p< 0.05). However, the highest value of fracture strength was when the denture was reinforced with fiber followed by orthodontic wire and chrome meshwork (p< 0.05). Conclusion: Within the limitations of the present study, it can be concluded that:
There is statistically significant difference present in the mean fracture resistance values in all groups. The weakest denture was when acrylic reinforced with 3% of nanoparticles. Followed by control, chrome, orthodontic and the highest fracture resistance was when the denture repaired with fiber reinforce.
