The modern systems have been designed to be as durable as possible, with no additional maintenance needed. However, proper oral hygiene is a standard requirement.
You should brush and floss regularly to eliminate the bacteria as well as regularly visit your dentist. This will not only prevent the system from deteriorating too quickly, but will also minimise the risk of other infections and diseases of the oral cavity.
Moreover, the dentist must regularly verify whether the osseointegration (integration of bone and the titanium screw) is stable and all elements are in good condition and work properly.
Also the dental implants are cleaned regularly with special tools, which do not damage their metal surface, hidden beneath the gums.
