Effect of Denture Cleansers on the Attachment System of Conventional and Digital Implant Retained Overdentures

Aim :An in vitro study was conducted to compare the effects of various denturecleansers solution on the retention of attachment systems in both conventional and digitalimplant- retained overdentures. Materials and Methods: The study was conductedaccording to the cleansing solution used, where divided equally into five groups: GroupA: the overdenture including retentive elements were cleaned by soaked in Corega tabsGroup B: soaked in chlorhexidine. Group C: soaked in Fittydent solution. Group D:soaked in Sodium hypochlorite solution. Group E: soaked in EDTA cleansing solution.Each group were placed into cleanser put in glass cup immersed in the solution duringthe entire soaking period according to the manufacturers’ instructions for the timeequivalent of 24 hrs., one month and six months. Acrylic blocks were held on a universaltesting machine for a pull-out test to record the dislodgement force. Measurementswere conducted after 1 months (T1) and 6 months (T2). Results: The study revealedthat, there were significant statistical differences between the different manufacturersregarding the retention forces of the attachment’s retentive force (Before soaking),(After 24hrs), (After 1month) and (After 6 months) where (p<0.001) Except in Coregagroup ,there is no statistical difference . For the cleaning solution groups, differentsignificant statistical results between five group at different time interval follow up.Where (p<0.001). Conclusion: Selecting denture cleaners that necessitate minimalsoaking time is vital for both conventional and CAD/CAM-based implant-retainedoverdentures with attachments, as it aids in extending the lifespan of the components.
