Abstract: It is difficult to fix the missing teeth in Papillon-Lefevre Syndrome(PLS) patients. PLS patients usually lose most of teeth early. The absorbed alveolar ridge is constrictive and the retentive force is weak in the overdenture of PLS patients. This paper reported one PLS case with the loss of the majority of teeth using magnetic attachment supported overdenture. After the restoration, the PLS patient’s denture function is good and the retentive force is strong. It suggests that magnetic attachment supported overdenture used in PLS patients with the loss of the majority of teeth is successful.
