초록

The purpose of this study was to compare the changes of retentive force in different stud attachment systems for implant retained overdenture.
Two commercially available attachments with different retentive forces were investigated: Kerator (pink, blue, red) and O-ring (orange, red). Twoimplant fixtures were vertically embedded in base mountings. Five pairs of each attachment were evaluated. A universal testing machine was usedto evaluate the retentive force of two attachments during wear simulation. Surface characteristics of each attachment system were evaluated withscanning electron microscopy. Five pairs of each attachment were evaluated. Kerator pink showed the highest initial retention. After 2,500 cyclesof wear-simulation, Kerator pink noted the largest decrease in retention. According to results of surface analysis, Worn surfaces were obtained inmatrices and patrices. Heavy wears were observed in matrices. After 2 year-wear simulation, most attachments exhibited retention loss.
Attachments using different kind of material exhibited dissimilar surface alterations.
