Effect of dynamic fatigue loading on the adaptation and retention of maxillary single dentures reinforced with digitally constructed zirconia and cobalt–chromium frameworks
Key Points
This research examines the impact of dynamic fatigue loading on maxillary dentures reinforced with zirconia and cobalt-chromium.
Dynamic fatigue loading was applied to maxillary single dentures.
Dentures were reinforced with either zirconia or cobalt-chromium frameworks.
Digital construction techniques were utilized for creating the frameworks.
Zirconia-reinforced dentures demonstrated better adaptation compared to those reinforced with Co-Cr under fatigue conditions.
Improved retention was observed in zirconia frameworks after dynamic loading.
Abstract
Maxillary single dentures reinforced with zirconia frameworks may represent a successful alternative to Co-Cr frameworks for prosthetic rehabilitation using digital technology.
