Change in the retentive force of Akers clasp for zirconia crown by repetitive insertion and removal test

ConclusionsWhen repetitive insertion/removal of the clasp was performed on MZC, retentive force decreased depending on clasp materials. However, the amount of decrease in retentive force was comparable or small compared to conventional FMC. As a result, it was suggested that MZC could be used on abutment tooth for RPD.
