An implant consists of three parts: the implant body (a screw-shaped artificial root in the bone), a connector (abutment) and the visible restoration on top, usually a crown. Unlike a bridge, an implant does not burden the neighbouring teeth, because they don't have to be ground down.
The process begins with careful planning, often with a three-dimensional X-ray (CBCT), to assess the available bone and the position of nerves. The implant is placed into the jaw under local anaesthesia. This is followed by the healing phase (osseointegration), during which the bone fuses firmly with the implant – usually six to twelve weeks, and in complex cases up to a few months. The abutment and crown are then fitted. If there is too little bone, a bone graft may be needed beforehand.
An implant is suitable for people with sufficient bone, healthy gums and good oral hygiene. Smoking and untreated periodontitis worsen the prognosis. With good care, implants often last ten to twenty years or longer.
As a guide (no guarantee), a single implant including the crown costs roughly CHF 3000 to 5000 in Switzerland; more with a bone graft or several implants. Basic insurance usually does not cover implants.
What to look out for: for an implant to last, consistent care and regular dental hygiene are decisive – otherwise the surrounding tissue can become inflamed (peri-implantitis). Careful planning and the experience of the practitioner also matter.
