Abstract
An articulator, specifically for applications in dentistry and dental technique, including a lower base (2) and an upper base (3) reciprocally attached at the joints (6, 7) placed at a variable height or distance from the base (3) of the articulator, in order to allow the occlusal plane of the dental arches to be positioned at the correct level on the condylar axis.
Claims19
An articulator, particularly for applications in dentistry and dental technique, including a lower base (2) and an upper base (3), reciprocally joined, with the possibility of moving the base (3) in relation to the other (2), suitable for holding the respective models (5, 4) of the patient's dental arches, characterised by the fact that it includes suitable means to vary the height or the distance of the occlusal plane relative to the said upper base (3) of the articulator.
Articulator according to one or more of the claims above, characterised by the fact that the said joints (6, 7) are present on the column portions of one of the said bases, with hollow seats (13) suitable for the above-mentioned joints, being positioned at the ends of the column portions of the remaining base.
Articulator according to one or more of the claims above, characterised by the fact that the said upper base (3) includes, on the side opposite the said column portions (9, 11), condylar boxes (14).
Articulator according to one or more of the claims above, characterised by the fact that the said upper base (3) can be used both with the said column portions (9, 11) coupled on the corresponding column portions (8, 10) of the lower base (2), in order to evaluate the degree of centric relation movement of the dental arches, and with the condylar boxes (14) resting on the same column portions (8, 10), in order to analyse the lateral movements of the same dental arches.
Articulator according to one or more of the claims above, characterised by the fact that it includes levels (19, 20) on both sides of the upper base (3) and one level (21) on the upper face of the base (2).
Articulator according to one or more of the claims above, characterised furthermore by the presence of:
- a millimetric vertical rod (26) for the height reading (H);
- a millimetric horizontal rod (26) for the length reading (L);
- and
- an incisal rod (28) for the reading of the angle (α);
- where (H), (L), and (a) define the position of the patient's dental arches.
Articulator according to one or more of the claims above, characterised by the fact that the upper base (3) includes a number of seats (29) suitable for inserting the incisal rod (28) in different positions relative to the articulator's median axis.
Articulator according to one or more of the claims above, characterised by the presence of a magnet (35) on the said cursor (17), suitable for making the latter integral with its respective joint (6, 7) in the position of the said base (3) that permits the analysis of the said lateral movements.
Articulator according to one or more of the claims above, characterised furthermore by the presence of suitable means to allow the selection of differentiated heights between the said joints (6, 7) and to maintain the parallelism of the said upper base (3) relative to the lower base (2).
Articulator according to the claims above, characterised by the fact that at least the said column portions (9, 11) are graduated.
Articulator according to one or more of the claims above, characterised by the presence of a goniometric scale on the said base (3), suitable to establish the angular position of the said condylar boxes (14).
