Definitions
- the present invention concerns dental separators that allow teeth to be temporarily separated without causing pain.
- the mechanism that activates the teeth-separating force is perpendicular to the dental arch and occupies a great deal of space, making it almost impossible to use said separator when it is necessary to work on the parietal sides of the teeth.
- the principal scope of the present invention is the creation of a dental separator characterised by the fact that it is constituted of four small separating wings, held together in couples by two supporting bars, that said supporting bars have at least one guide per pivot each, that said pivot is a separating pivot that is inserted with its smooth area into said guide that has a ridge for the blocking ring and is screwed in with the threaded part in the opposing guide for a threaded pivot, that said separating pivot is screwed in by a screwdriver with a handle and a head with a hook that is inserted into the hole for the hook of the separating pivot.
- the supporting bars have a separating pivot and a stabilizing pivot at the base, and that said stabilizing pivot is fixed in a pivot guide and is inserted into the opposite guide where it can move freely.
- the supporting bars have a separating pivot set on the upper central part of said supporting bar.
- the separating pivot is inserted with the smooth part in the guide having the ridge for the blocking ring and is screwed in with the threaded part into the opposing guide for a threaded pivot.
- the screwdriver has a handle and a head with a hook.
- the screwdriver has a handle and a cross-head that is inserted into the corresponding cross-cavity made in the separating pivot to screw in the same.
- Figure 1 represents a view of a screwdriver for activating a separator, object of the present invention.
- Figure 2 represents an assonometric view of a separator, object of the present invention.
- Figure 3 represents a lateral view of a separator, object of the present invention.
- Figure 4 represents a view from above of a separator, object of the present invention.
- Figure 5 represents an assonometric view of a second way of constructing a separator, object of the present invention.
- Figure 6 represents a lateral view of a second way of constructing a separator, object of the present invention.
- Figure 7 represents a view from above of a second way of constructing a separator, object of the present invention.
- the dental separator object of the present invention is constituted by four small separating wings (1), held together in couples by two supporting bars (2), said small separating wings (1) have two curves, one longitudinal and one transversal, in order to adhere better to the lateral surface of the teeth that one intends to separate.
- the supporting bars (2) each have at least one guide (3) for each pivot.
- One of said pivots (4) is a separating pivot, cylindrical in shape, which has a hole for a hook (5), a smooth area (6), a blocking ring (7) and a threaded part (8), that is screwed into the guide for a threaded pivot (9).
- the separating pivot (4) is screwed in by using a screwdriver (10), which has a handle (11) and a head with a hook (12).
- the hook (12) can be substituted by a cross-head, which is inserted into the corresponding cross-cavity made in the separating pivot for screwing in the same.
- the supporting bars (2) have a separating pivot at the base (4) and a stabilising pivot (13).
- the separating pivot (4) is inserted with the smooth area (6) in a guide (3) that has a ridge (14) for the blocking ring (7) and is screwed in with the threaded part (8) in the opposing guide (3) for a threaded pivot.
- the stabilising pivot (13) is fixed into a guide (3) for a pivot (4) and is inserted into the opposing guide (3) where it can move freely.
- the dental separator, object of the present invention is inserted between two teeth and by activating the separating pivot (4) with the screwdriver (10), the pivot guides (3) are separated because the separating pivot (4), unscrewed, forces the threaded pivot guide (3) in one direction and the ridge (14), present on the opposing pivot guide (3), in the opposite direction.
- the dental separation occurs with the small separating wings that adhere perfectly to the surface of the teeth to be separated, and the presence of the two curves does not permit the separator to fall onto the gums and therefore, because there is no other contact with any other material, this discovery makes the operation non-traumatic.
- the supporting bars (2) have a separating pivot (4) placed on the upper central part of said supporting bar (2).
- the separating pivot (4) is inserted with the smooth area (6) into the guide (3) that has the ridge (14) for the blocking ring (7) and which is screwed with the threaded part (8) into the opposing guide for a threaded pivot (3).
- the dental separator of the present invention can also be used to separate non- adjoining teeth, as illustrated in figures 6 and 7. It functions in the same manner, and there is no need for any modification to the separator.
- the present invention permits numerous advantages and to overcome difficulties that could not have been overcome with the systems at present on sale.
