The presence of comorbidities and increased infection risk can, for example, lead to a higher risk of implant loss.

The aim of all considerations is to keep the risk of infection for the patient with a disease history to a minimum and to strive for an appropriate functional and esthetic therapeutic success. Particularly in the esthetic zone, in addition to the general health risks of the surgical procedure, esthetic aspects are increasingly taken into account in planning.
