| Abstract | ||
| Aims: To evaluate the load at fracture for different mandibular over–dentures and the positions of thefracture area for these designs. Material and methods: Ten mandibular dentures were made, each oftwo designs. The first design consisted of acrylic resin over–denture supported by two dome–shaped 3mm mandibular canines copings, the second design consisted of two dome–shaped copings connectedwith a rigid metallic bar. The mean and standard deviation were calculated in addition to the analysis ofvariance which showed a significant difference at P < 0.05. Results: Showed that the over–denturesupported by two dome shaped mandibular canines were more fracture resistance than the over–denturesupported with the bar. The fracture position depends on the denture design. Conclusions: The resultsindicated that the denture made entirely of acrylic resin was much more stronger than the denture withless thickness due to the incorporation on metallic rigid bar. | ||
