The software coDiagnostiX facilitates the exact planning of dental implants. The entire planning process is performed directly on our PC. Especially important is the complete three-dimensional planning, which offers complete new views. They are used to increase the planning safety and also as added information in conversation with the patient. All available implants are deposited graphically in the integrated implant data base and can be sorted hierarchically for a fast selection. The system clarifies the important question of bone density in the proposed operation area.
