After a very successful series of eight previous Treatment Guides, it seems logical to consider patients as they grow older and may become frail and more dependent on care. Volume 9 of the ITI Treatment Guide attests to the ITI's holistic approach to implant dentistry and to its professional responsibility for patients who have aged with implant-supported restorations in place, as well as for patients at a more advanced age who, until late in life, can benefit from the progress we have made in terms of the materials and techniques that present-day implant dentistry has to offer.
