Abstract

When attempting to restore the oral function of a partially edentulous patient, there are a number of prosthetic treatment options available, depending on the structure of remaining teeth. For example, when only one set of maxillary and mandibular teeth are diagonally in place across from each other, it is difficult to gain stable occlusion. In this case, implants can be put in place at the corresponding edentulous area to achieve balance. By doing so, a stable occlusion can be achieved. For this case report, a patient with crossed occlusion after extraction was treated with maxillary RDP (removable dental prosthesis) and mandibular implant-supported RDP (removable dental prosthesis). Moreover, an implant fixture was placed under the posterior molar of the distal extension base diagonally across from the remaining maxillary teeth. Then, magnetic attachment was implemented. According to the patient who received the treatment, the result was functionally and aesthetically satisfactory.
