Abstract

The tooth contact pressure tester has a handle (1) with a reinforced fork (2) having jaws with conical recesses (3,4). The fork receives a dental wire with spaced balls (6) or rings. The position of the cones (3,4) on the fork allows variation in tension in the wire.

Description

-1- La présente invention concerne un dispositif pour tester la pression-1- The present invention relates to a device for testing the pressure

d'un point de contact entre deux dents(Frig.1) a point of contact between two teeth (Frig. 1)

Cette invention intervient soit pour une reconsti- tution partielle d'une dent soit pour la pose d'une prothèse. This invention is used either for a partial reconstruction of a tooth or for the placement of a prosthesis.

Ce point de contact est traditionnellement testé par le passage entre les deux dents, d'un fil dentaire, lequel fil est enroulé entre les doigts du praticien et manipulé en bouche. Dans le but d'éviter une telle manipulation, un This point of contact is traditionally tested by the passage between the two teeth, a dental floss, which thread is wound between the practitioner's fingers and manipulated in the mouth. In order to avoid such manipulation, a

brevet Européen apporte une solution proche de notre dispositif mais solution totalement différente. European patent brings a solution close to our device but totally different solution.

En effet ce brevet n0 0287 039 sous priorité AT 982/87 du 14.04.87. est entièrement mécanique, d'une Indeed, this patent n ° 0287 039 with priority AT 982/87 of 14.04.87. is entirely mechanical, of a

réalisation technique complexe et n'offre pas les tensions15 différentes que déclenchent les praticiens sur les fils dentaires lors des tests de point de contact. complex technical achievement and does not offer the different tensions15 that practitioners trigger on dental floss during point of contact tests.

Contrairement à ce brevet Européen, le dispositif selon notre invention permet plusieurs tensions de fils dentaires selon l'appréciation du praticien au cours de20 son intervention. Le dispositif permet soit un test mécanique, soit semi-mécanique, soit manuel: - le test mécanique par le blocage des deux boules (Fig.2 et fig. 3) dans les cônes supérieurs; ce type de test permet une tension plus importante du fil dentaire en passant les boules dudit fil dans les cônes inférieurs (Fig.4 et fig.5). Ce type de test exige un fil dentaire selon le modèle à boules de la fig.6. Les boules pouvant le cas échéant être Unlike this European patent, the device according to our invention allows several tensions of dental floss according to the appreciation of the practitioner during his intervention. The device allows either a mechanical, semi-mechanical or manual test: - mechanical test by blocking the two balls (Fig. 2 and Fig. 3) in the upper cones; this type of test allows greater tension of the dental floss by passing the balls of the dental floss through the lower cones (Fig. 4 and fig. 5). This type of test requires dental floss according to the ball model in fig. 6. The balls which can if necessary be

remplacées par des éléments au volume différent. replaced by elements with different volume.

selon les fig.7, 8.9 le fil dentaire enroulé dans according to fig. 7, 8.9 the dental floss wound in

- le test semi-mécanique par le blocage d'une boule en 3 et la tension manuelle en 8, à partir d'un anneau serti sur ce modèle de fil dentaire (Fig.1) - le test manuel à partie du passage du fil dentaire dans - 2 - La fourche démunie de son manche (Fig. 13). Ce fil est tendu par traction sur les anneaux 8 et manipulation 9 du praticien (Fig 13). Le test manuel pouvant en cas de besoin se compléter par la tension du fil (Fig.14) simplement par l'écarte- ment des anneaux passés aux doigts du praticien et la pression du fil entre deux autres doigts du praticien (Fig 15). Ce fil dentaire, comme les autres mentionnés ci- dessus et dessiné, s'enroule dans un boitier et se coupe dans les intervalles désirés (Fig 7 Fig.8.& 9)en 7. Quelque soit les tests choisis un réservoir à encre - the semi-mechanical test by blocking a ball in 3 and manual tensioning in 8, from a ring crimped on this model of dental floss (Fig. 1) - the manual test from the passage of the wire dental in - 2 - The fork without its handle (Fig. 13). This wire is stretched by traction on the rings 8 and manipulation 9 of the practitioner (Fig 13). The manual test can, if necessary, be completed by the tension of the thread (Fig. 14) simply by spreading the rings passed over the practitioner's fingers and the pressure of the thread between two other practitioner's fingers (Fig 15). This dental floss, like the others mentioned above and drawn, is wound in a box and is cut in the desired intervals (Fig 7 Fig. 8 & 9) in 7. Whatever the tests chosen, an ink tank

Un encreur en modèle quelconque étant dessiné (Fig 11 & 12)15 Le manche 1 du dispositif selon l'invention peut se visser sur la fourche 2 ou peut être solidaire de celle- according to a suitable model will allow the dental floss to be impregnated and thus mark the point of contact. An inkpad of any model being drawn (Fig 11 & 12) The handle 1 of the device according to the invention can be screwed onto the fork 2 or can be secured to it

Claims

1) Device for testing the pressure of a contact point between two teeth, characterized in that it is composed of a handle (1) at the end of which a reinforced fork (2) provided with four notch cones ( 3,4), allows

the insertion of dental floss with balls or similar elements

blocking areas, to generate different voltages

according to the appreciation of the practitioners, the thread passing

in the slot (7).

2) Device according to claim i characterized in that the fork (2) has a certain resilience allowing the dental floss, during the passage of the notches 3
