Abstract

Crossed occlusion can be treated either by overdenture and telescopic denture or by placing an implant at the edentulous area to reestablish the support on the occlusion. If alveolar bony support is sufficient and an the environment where an implant is inserted is favorable to restoring the masticatory and aesthetic function of a patient, the implant-supported fixed prosthesis can provide more definitive occlusal support and more aid for other oral functions. In this case report, a patient with a severe residual alveolar bone resorption following the extraction of teeth and who had a crossed occlusion was treated with sinus bone graft and alveolar bone augmentation in order to place the implants at prosthetically position. The definitive restoration was made to reflect the patient's occlusal and aesthetic function using the CAD/CAM double scanning method. Finally, the treatment had the masticatory and aesthetic function adequately restored, which is reported here.
