Implants are false toothroots, which are anchored in the jawbone, upon which the selected tooth substitue can be mounted. Implants are expensive and time-costing, have however the advantage, that other tooth substitutes do not have.
Being screwed into the jawbone, the implants are strongly anchored and feel like the original teeth. The strain on the jawbone stays the same, so that bone decline – a side effect of tooth loss – can be eliminated. Beside that, neighbouring teeth must not be ground, which is necessary by the preparation from other tooth substitutes.
Implants can also serve as „anchorposts“ and give bridges or prostheetics extra stability. Implants can be normally used by all patients, minimun age is however 16-27 – a fully developed jaw is necessary – and enough bone substance available for a secure fitting.
