After resection of the odontogenic lesion the sinus wall was reconstructed with a prebended 3D titanium-mesh using CAD CAM technique. This work provides a new treatment device for maxillary reconstruction via rapid prototyping procedures. Keywords Computer-assisted surgery rapid prototyping ondontogenic lesion Background Loss of hard and soft tissue structures of the midface due to resection of odontogenic lesions can be associated with substancial functional and aesthetic deficits 1 . Conservative treatment due to simple resection and primary soft-tissue clouser will result in loss of soft and hard tissue support. Radical excision of tumor followed by adequate reconstruction can improve survival and provide more satisfactory functional and aesthetical outcome. Reconstruction of large maxillary defects following ablative surgery could be done by using vascularized bone transfer or more often primarily with simultaneous or delayed bone grafting 2 . Another option for maxillary reconstruction might be the use of computer-assisted prebended titanium meshes which acts as physical three dimensional supports of soft and hard tissue 3 . Computer aided design modeling CAD CAM software that allows mirroring planning coupled to navigation systems has dramatically improved surgical strategies in reconstructive surgery of the craniomaxillo-facial skeleton 4 . A major challenge in planning procedures is that virtual reconstruction is based on a true-to-original reconstruction with a patient .
