ProsthodonticsIndirect retainers are components of removable partial dentures that help to prevent the denture from dislodging during function. They are ideally placed as far anteriorly from the fulcrum line (the line around which the denture rotates) as possible. This positioning helps to provide stability and support to the denture, counteracting the forces that could dislodge it.
