Abstract: The invention concerns a t-plate for detachable fixing of false teeth components to one another or to the remaining teeth, with a female part that displays a recess, a male part (6) that displays an attachment section (8) that can be brought to engage the recess in the female part and displays a continuous slot (18) that extends at least through the attachment section (8) and divides the latter into two parts (8a, 8b), and a spreading device (22, 24) that spreads the two attachment section parts (8a, 8b) and displays a first spreading means that is arranged in the slot (18) and is situated so as to engage the two attachment section parts (8a, 8b). The special feature of the invention consists in the fact that the spreading device (22, 24) displays at least one additional spreading means (24) arranged in the slot (18) at a distance from the first spreading means (22a).

Abstract: The invention is concerned with a method and an equipment for forming prosthetic tooth structures for fastening to implants, where at least one pattern is produced from the portion of a patient's jawbone containing the implants and pattern sockets of metal is arranged in it at a place which corresponds with the position of the implant in the patient's jawbone, and a prosthetic tooth structure is produced from metal with the aid of the pattern.
