 The subject was a 83-year-old female who lost her bilateral molar occlusion due to the bilateral upper free-end and multiple tooth loss. A X-ray image showed alveolar bone resorption due to advanced periodontal disease, malalignment, and the collapse of the occlusal plane. Stress-bearing ability and preservability of the upper and lower remaining teeth were examined, followed by a thorough consultation with a patient regarding the esthetic recovery based on the diagnostic wax-up. Provisional restoration was placed in the upper jaw to correct the occlusal plane and tooth alignment. The crowns of the lower remaining teeth were truncated, and treatment overdenture was placed. The patient was followed for several months, and final restoration was placed after confirming that there are no functional and esthetic problems. For the design of the final restoration, radicular attachments using magnetic attachment and MT crowns were chosen in the lower jaw, and porcelain-fused-to-metal crown and extracoronal magnetic attachment were chosen in the upper jaw.

 The patient is satisfied with functional and esthetic results. Postoperative prognosis at 3 years and a half after the placement of new dentures is satisfactory.
