Sažetak
Magnetodent is a teaching aid for visual interpretation of aberations in tooth position in transverse and sagittal planes, with the possibility of comparison v/ith the normal dental arch. The aid also enables 'measuring the malposition of individual teeth and of the dental arch in metrical units. The measurements of the ideal upper dental arch are based on the Pont's Index, one millimetre in nature represented by one centimetre on the device. Description: Two rubber tapes (11a) provided with two grooves are inserted in two U-type metal rods (10) held in parallel horizontal position by two vertical rods containing the supports. A tin panel (9) with traced in a normal dental arch and anatomic details relevant for the determination of the median line is placed in the back groove (11b). The teeth (1—7) made of white plastic sheet 2 mm thick — forms, drawings and measures analogous to the drawing in the tin panel — with round magnetized sheets φ 1 cm (8) glued to the back, are put m the wanted position over the tin panel. A sliding plexiglass sheet 3 mm thick (12a) devided into fields of 1 sq. cm. (12b) in the front groove (11d) is used for performing exact measurements of the aberations. When the change of the position of the teeth is required this sheet is slid to the right or to the left to enable the operation. Dimensions of the prototype: 56 cm x 50 cm. The same principle can be applied for the mandible changing the tin panel in the back groove (11b).
