Overdenture is a partial denture or full denture that covers all the root surface or implant. Overdenture can use tooth, tooth root or implant as an abutment. An attachment can be used to add more retention. Magnet and stud attachment is often used for this purpose. The aim of this research is to know the retentional force difference between overdenture using magnet attachment and stud attachment (MDI). The study was conducted on 10 acrylic plates size 50x10x10 cm for each attachment. Magnet (MAGFIT TM DX) dan stud attachment (MDI IMTEC 3M) were used on lower jaw edentulous model made from acrylic. Magnet was then attached to acrylic plate and the keeper attached to edentulous model, on stud atachment (MDI) the male attachment (implant) was attached to edentulous model and the female attachment (metal housing) attached to acrylic plate. The overdenture was then attached to the modified Van Kampen. Retention was then measured by pulling the acrylic plate which has been attached to edentulous model. Statistical method using independent t-test with significance α = 0.05. The result showed that there was a significant difference between overdenture using stud attachment (MDI) and overdenture using magnet attachmet (p<0.05). In conclusion, the overdenture using stud attachment provide more retention than overdenture using magnet attachment.
