It is a fact that thc demographics of society today rellect a significant change. Not only do we live much longer while still retaining high cxpcctation in terms of hcalth and quality of life, but the ratio of old to young people has also shifted, with the older generation signisicantly outnumbering the younger. This has brought with is a new set of demands on implant dentistry and on its practitiones, who more routinely en-counter elderly patients. The treatment of these patients is subject to certain limitations and requires compromises. And along with elderly paticnts who still cd an active life, there are also those who are more frail, whose health has been compromised, or who require special dental care. This changing situation requires well considered and adequate solutions.
