Abstract
Objective: To compare the retention of ball attachments versus locator attachments in implant-supported mandibular overdentures during 5000 insertion and removal cycles.
Methodology: This quasi-experimental study was conducted from January 2022 to October 2023. The sample size was 20 edentulous mandibular models and overdentures adequately seated with their respective housings. The overdentures were subjected to 5000 cycles of dislodging force using a universal testing machine, and the maximum loads needed to disengage the overdenture were measured for each cycle. The force values were then calculated. The data were analyzed using SPSS 22.
Results: There was a significant difference in retentive forces between ball and locator types of attachments (p<0.001). The locator type had better retentive forces (52.45±4.97) than the ball type (32.61± 4.28). During the cycles, there was a decrease in retention in both types of attachments. Pearson's correlation showed a strong negative correlation between the number of pulls and retention in both types of attachments. The locator type showed a significantly lower retention loss than the ball-type attachment.
Conclusion: The locator attachment mechanism was more favorable from a clinical standpoint. The drop in retention was attributable to both attachment systems; it was substantially lower in the case of the locator attachment system.

Key words: Denture bases, denture retention, overdenture, prosthodontics.
