The subject of prostheses on attachments is discussed with particular reference to the biomechanical aspects of tooth-borne dentures and extension-base-dentures. Commercial attachments can be classed as precision attachments and stress-breakers. The indications for the employment of each kind in accordance with individual situations and the degree of edentation are explained. The resort to attachments is, in any event, a compromise solution undertaken primarily for cosmetic reasons. Some types of attachments directly created in the laboratory, or controlled load distribution prostheses employing wired, enable a more personal solution to be elaborated to suit the needs of a given case.
