Harmonie entre la fonction, l'esthétique et la biologie
La combinaison unique des caractéristiques indépendantes de l'Astra Tech Implant System BioManagement Complex garantit un résultat fiable, prédictible et esthétique à la fois sur le court et le long terme. **14
OsseoSpeed : accélération de la formation et de la cicatrisation osseuse**15
Surface en titane modifiée au Fluor avec une structure de surface unique à l'échellenanométrique pour une stimulation précoce de la cicatrisation osseuse et une accélération du processus de cicatrisation osseuse.
MicroThread : stimulation biomécanique de l'os**15
Micro-filetage sur le col de l'implant qui permet une distribution optimale des charges et réduit la valeur des contraintes.
Conical Seal Design : ajustage fort et stable
Connexion conique qui assure aussi un scellement hermétique de la partie interne de l’implant
par rapport aux tissus environnants réduisant ainsi considérablement les micro-mouvements et les micro-infiltrations.**17
Connective Contour : optimisation du volume et de la zone de contact des tissus mous
Contour créé par la connexion du pilier dans l’implant.
