Patiente de 64 ans venue avec une ancienne prothèse mixte fixe-mobile. La patiente est en bonne santé et non fumeuse. La patiente a exprimé le désir d’avoir ses dents fixées. Nous décidons d’extraire tous les éléments dentaires, de placer 6 implants pour ensuite réaliser une prothèse vissée.
Solution is All-on-4 procedure with following preparation of the removable prothesis on a titanium bar. The bone reduction of irregular lower jaw edges is made. 2 pcs 4,3×9 mm EL C-Tech implants are placed in 31 and 43 positions. 2 pcs 4,3×11 mm EL C-Tech Morse locking implants are placed in 35 and 45 positions under 30° angle.
The success of any complex dental treatment depends on proper diagnostics and treatment planning. Digital treatment planning, prosthetic backward planning and guided implant surgery can help improve success rates and predictability of complex rehabilitations.
After developing our model, it is acquired by means of a structured-light scanner. Once the master model has been acquired, the virtual processing starts with Exocad. When the 3D virtual model is obtained, the tooth library to be used on the model is selected and the virtual design phase starts.
