Abstract
The aim of this study was to compare the changes in retentive force of stud attachments for implant overdentures by
Three commercially available attachment systems were investigated: Kerator blue, O-ring red, and EZ lock. Two implant fixtures were embedded in parallel in each custom base mounting. Five pairs of each attachment system were tested. A universal testing machine was used to measure the retentive force during 2500 insertion and removal cycles. Surface changes on the components were evaluated by scanning electron microscopy (SEM). A Kruskal-Wallis test, followed by Pairwise comparison, was used to compare the retentive force between the groups, and to determine groups that were significantly different (α<.05).
A comparison of the initial retentive force revealed the highest value for Kerator, followed by the O-ring and EZ lock attachments. However, no significant difference was detected between Kerator and O-ring (
After 2500 insertion and removal cycles, all attachments exhibited significant loss in retention. Mechanism of retention loss can only be partially explained by surface changes.

Two implant fixtures were embedded in parallel in each custom base mounting. Five pairs of each attachment system were tested. A universal testing machine was used to measure the retentive force during 2500 insertion and removal cycles. Surface changes on the components were evaluated by scanning electron microscopy (SEM). A Kruskal-Wallis test, followed by Pairwise comparison, was used to compare the retentive force between the groups, and to determine groups that were significantly different (α<.05).</p></sec><sec><title>RESULTS</title><p>A comparison of the initial retentive force revealed the highest value for Kerator, followed by the O-ring and EZ lock attachments. However, no significant difference was detected between Kerator and O-ring (<italic>P</italic>>.05). After 2500 insertion and removal cycles, the highest retention loss was recorded for O-ring, and no significant difference between Kerator and EZ lock (<italic>P</italic>>.05). Also, Kerator showed the highest retentive force, followed by EZ lock and O-ring, after 2500 cycles (<italic>P</italic><.05). Based on SEM analysis, the polymeric components in O-ring and Kerator were observed to exhibit surface wear and deformation.</p></sec><sec><title>CONCLUSION</title><p>After 2500 insertion and removal cycles, all attachments exhibited significant loss in retention. Mechanism of retention loss can only be partially explained by surface changes.</p></sec></abstract><kwd-group><kwd>Overdenture attachment</kwd><kwd>Resilient attachment</kwd><kwd>Surface wear</kwd><kwd>Retention</kwd></kwd-group><funding-group><award-group><funding-source country="KR">Small and Medium Business Administration</funding-source><award-id>C0250225</award-id></award-group></funding-group></article-meta></front><floats-group><fig id="F1" orientation="portrait" position="float"><label>Fig. 1</label><caption><title>Custom base mountings fabricated using acrylic resin.
