Implants serve to improve the function of the existing teeth or to completely overtake their role. An implant replaces the tooth root thusly preventing or slowing down bone resorption. An implant is fitted when it is no longer possible to fit a crown or a bridge construction on the existing tooth. It solves the problem of one or multiple missing teeth, or even complete toothlessness. It is fitted under local anaesthesia and minimal surgery. If the patient practices proper oral hygiene the implant can last for life. In order to be sure we can fit the implant, we need to do a complete health check-up of the patient i.e. inspect the bone structure where the implant is to be fitted. A patient who wishes to fit an implant must have a sufficient width and height of the bone ridge. If a patient is missing bone structure, it is possible to reconstruct i.e. replace it, which is called augmentation. In this situation we surgically replace the lost bone structure with special artificial materials. Depending on the situation, an implant can be fitted after the healing or immediately.
