Aim :An in vitro study was conducted to compare the effects of various denture
cleansers solution on the retention of attachment systems in both conventional and digital
implant- retained overdentures. Materials and Methods: The study was conducted
according to the cleansing solution used, where divided equally into five groups: Group
A: the overdenture including retentive elements were cleaned by soaked in Corega tabs
Group 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 during
the entire soaking period according to the manufacturers' instructions for the time
equivalent of 24 hrs., one month and six months. Acrylic blocks were held on a universal
testing machine for a pull-out test to record the dislodgement force. Measurements
were conducted after 1 months (T1) and 6 months (T2). Results: The study revealed
that, there were significant statistical differences between the different manufacturers
regarding 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 Corega
group ,there is no statistical difference . For the cleaning solution groups, different
significant statistical results between five group at different time interval follow up.
Where (p<0.001). Conclusion: Selecting denture cleaners that necessitate minimal
soaking time is vital for both conventional and CAD/CAM-based implant-retained
overdentures with attachments, as it aids in extending the lifespan of the components.
