Dental implants can last a lifetime, unlike bridges, partials and dentures that may need to be replaced several times. Unlike bridges, partials and dentures, a dental implant replaces the lost tooth root, which will prevent jaw bone resorption that occurs with bridges, partials and dentures. The loss of tooth roots will cause a change of the smile and contours of the face over time. A bridge, once the common single-tooth replacement method, requires the alteration of each neighboring healthy tooth, which is cut down and shaped to accept a crown. With a dental implant treatment, there is no compromise to adjacent teeth. The lost root and crown is replaced leaving neighboring healthy teeth in place. Removable partials connect to healthy teeth by hooks. Partials may be removed for cleaning and may need to be replaced often. A partial hook connected to healthy teeth will create tooth stress and will loosened the healthy teeth over time. Full arch dentures and partials have the added disadvantage of accelerating the bone resorption process, which, among other things, causes the appearance of premature aging.
