To achieve this goal, we made use of CT scans, SimPlant plan- ning software, the new Zimmer Guided Surgery Instrumenta- tion and the new Immediate Smile model. The patient was a 49-year-old white female in good health, completely eden- tulous in the maxilla and wore a complete upper denture. On the lower jaw, she wore an im- plant-retained over-denture. The planning phase for the case began with a CT scan uti- lising the i-Cat and the Dual Scan protocol. The patient’s ex- isting denture was transformed into a scan prosthesis by glu- ing eight Dual Scan Markers onto the surface. A radiolucent bite index was made to secure the prosthesis in the correct position. The patient was first scanned in the i-Cat 17–19 while wearing the conversion prosthesis and the bite index. In a second scan, the conver- sion prosthesis was scanned alone. The resulting CT data was loaded into SimPlant, and the scan prosthesis was super- imposed upon the study using the SimPlant Dual Scan wizard (Fig 1). Using SimPlant, the opti- mum implant positions were determined, based upon avail- able bone with a minimum of 3mm between implants, and the design of the final restora- tion (Fig 2). The resulting treat- ment plan was submitted for fabrication of a SurgiGuide and an Immediate Smile model. I received the Immediate Smile model, which contained a duplicate of the scan prosthe- sis, a bone model with a silicone soft tissue, and a mucosa-sup- ported SurgiGuide. The bone model came with eight open- ings corresponding to each of the eight implant positions as designed in the SimPlant plan and corresponding exactly in size to the dimensions of Zim- mer analogues. The bone model came with a screw fixation system, which Immediate restoration in the fully edentulous maxilla region Dr Max Cohen presents a clinical case ‘The bone model came with eight openings corre- sponding to each of the eight implant positions as designed in the SimPlant plan ’ page 22DTà
