<p>A base structure (10) for a dental prosthesis comprises a first and second anchor elements (14) and (16) which are permanently securable to the teeth on opposite sides of a space or gap (22) in the tooth structures of a patient and a base element (12) which is securable to the anchor elements (14) and (16) in the gap (22) but which comprises slidably interfitted first and second base element portions (32) and (34) so that it is expandable to fit the width of the gap (22). The method of securing and forming a dental prosthesis in the gap (22) with the base structure (10) comprises the steps of securing the anchor elements (14) and (16) on the teeth on opposite sides of the gap (22), assembling the base element (12) with the anchor elements (14) and (16) in the gap (22), securing the first and second base element portions (32) and (34) together, forming an outer shell (68) on the base element (12) and securing the base element (12) with the outer shell (68) thereon to the anchor elements (14) and (16).</p> |
