Abstract:
Recent improvement of Implantology driven by computers deeply changed our point of view to treat patients. Using a CT scan based planning system, the surgeon is able to select the optimal location for implant placement. The SimPlantTM program allows implant planning in 2D and 3D. Precise osteotomy control is performed using stereolithographic surgical guides. The SAFE SystemTM is a serial instrumentation allowing transfer of planned implant positions to the mouth. Accuracy is not only related to security in implant placement, also to aesthetics, placing implants in their optimum position even in fresh extraction sites to preserve bone environment. Accuracy in implant placement allows not to open flap with a precision up to 0.2 mm. Pain and swelling are reduced to nearly nothing using trans-mucosal approach.
Since vertical control of implant placement opened the way to the Immediate SmileTM protocol. In this protocol, the bridge is made before the surgery without taking an impression and placed in the mouth during the same appointment as the surgery. The unique part of this procedure comes from the fact that the temporary bridge is screw retained on the implants without been relined and without using fancy and expensive components. In Computer driven implantology, accuracy allows using long trans-sinusal implants anchored in the zygoma or in the pterygoid bone, without opening sinusal lateral windows. Even in the presence of minimum volume of basal bone, anchorage is very stable and can be used to immediately load prostheses. When flap access in not required a surgical guide can be used with either mucosal or teeth support.
The SimPlantTM program is used to analyze CT scan data and make an implant planning in 2D and 3D, SurgiGuidesTM and SAFE SystemTM used to accurately place implants in the mouth and Immediate SmileTM components to deliver a fixed restoration in the same appointment as implant placement. Based on this concept, treatment can be individualized to meet the unique needs and concerns of each patient and each dentist.
