An anchorage unit (41, 44) fits to a dental implant (5). A dental attachment (31, 32) for mounting to the anchorage unit comprises a first attachment part (31) and a second attachment part (32). The attachment parts (31, 32) define an aperture (24) for accommodating a portion (44) of the anchorage unit with a boundary wall of the aperture (24) on each of the attachment parts serving, in use, as a jaw for clamping against the portion of the anchorage unit. The aperture is of greater size than the portion of the anchorage unit to allow adjustment of the position of the attachment with respect to the anchorage unit. In another embodiment, a two-part anchoring assembly defines a pair of jaws for, in use, receiving and clamping against a portion of a dental attachment. The apparatus is particularly relevant when an attachment must be placed on more than one implant simultaneously. |
