Abstract

Angle-measurement device. Angle-measurement device which can be used for measuring any angles with respect to a horizontal axis, characterised in that it comprises a horizontal level 1, an angle measurement scale A calibrated from 0 DEG to 90 DEG on either side of a central axis B. Mobile needles 2 and 3 which move and mark the degrees. Angle-measurement device according to Claim 1, characterised in that the level is integral with the axis B and cannot move, only the needles being mobile.

Description

La présente invention conoerne l'utilisation d'un niveau d'eau pour déterminer un plan horizontal en art dentaire. Elle permet aussi de calculer l'angulation par rapport à cet axe. The present invention relates to the use of a water level to determine a horizontal plane in dentistry. It also makes it possible to calculate the angulation in relation to this axis.

Dans les données factuelles les plans prothétiques sont choisis d'a- près des rapports anatomiques, complétés par des mesures obtenues par des arcs faciaux. En fonction de ces mesures chaque fabricant d.e dents a des données bien précises pour effectuer le montage de celles-oi. In the factual data, the prosthetic plans are chosen from anatomical reports, supplemented by measurements obtained by facial arches. Based on these measurements, each tooth manufacturer has very precise data for mounting them.

L'angnlationique doivent avoir les cuspides est bien déterminée, mais aucun moyen de mesure n'est donné pour réaliser l'évaluation de ces in- dications, celles-ci sont faites approximativement et sans contrôle précis possible. De plus, dans l'établissement d'un diagnostic sur mode le, il n'y a pas actuellement d'instrument de mesure permettant d'évaluer l'angulation cuspidienne. The angularity must have the cusps is well determined, but no means of measurement is given to carry out the evaluation of these indications, these are made approximately and without precise control possible. In addition, in the establishment of a diagnosis on the LE mode, there is currently no measuring instrument making it possible to evaluate the cuspid angulation.

a) En dentisterie opératoire, l'angulométre permet l'étude d'un mo dèle avant une intervention nécessitant un meulage d'équilibration fono- tionnel. L'angulation donnée par l'appareil posé sur les cuspides indique les points de surplomb, ceux-ci repérés sont marqués. L'on peut contrôler le résultat sur une empreinte après intervention. a) In operative dentistry, the angulometer allows the study of a model before an intervention requiring a functional balance grinding. The angulation given by the device placed on the cusps indicates the overhang points, these identified are marked. You can check the result on an impression after surgery.

b) En orthodontie, avec l'angulomètre un complément de diagnostic est possible, l'on peut calculer le degré d'inclinaison des cuspides par rapport à la courbe da Wilson. b) In orthodontics, with the angulometer an additional diagnosis is possible, one can calculate the degree of inclination of the cusps relative to the curve of Wilson.

o) En prothèse dentaire, pour le montage des dents postérieures, l'angulomètre permet de monter sur un même plan et aussi avec l'angula- tion voulue. Ceci, pour les cas les plus courants. En oas de dissymétrie condylienne, selon les indications données par le praticien, l'on peut sur un m8me plan, avec des inclinaisons cuspidiennes différentes avoir un artioulé correct avec des données respectées et vérifiées, inolinaison voulue sur un m8me plan horizontal. o) In dental prosthesis, for mounting the posterior teeth, the angulometer makes it possible to mount on the same plane and also with the desired angulation. This, for the most common cases. In the case of condylar dissymmetry, according to the indications given by the practitioner, it is possible, on the same plane, with different cusp inclinations, to have a correct articulation with respected and verified data, desired inolination on the same horizontal plane.

Ceci n'était obtenu à oe jour, que d'une façon approximative et lais sé à l'appréciation du technicien. Le prothésiste dentaire, avec l'utilisation de l'angulomètre obtient des montages rationnels. Les indications et le diagnostic du praticien sont ainsi respectés. This was only obtained so far, only approximately and left to the discretion of the technician. The dental technician, with the use of the angulometer, obtains rational arrangements. The practitioner's indications and diagnosis are thus respected.

D'après le dessin on peut voir que L'angulomètre comprend trois parties montées sur un axe.. From the drawing we can see that the angulometer has three parts mounted on an axis.

a) Un niveau d'eau horizontall
b) Deux aiguilles mobiles 2 et 3
c) Un cadran étalonné monté sur un support central, marquant les de- grés à droite et à gauche de 0 à 900, A
d)Un axe relie le tout, le niveau peut en être solidaire, l'ensemble est ainsi stable B
Ces quatre parties ressortent sur le dessin sans erreur possible.
a) A horizontal water level
b) Two movable hands 2 and 3
c) A calibrated dial mounted on a central support, marking the degrees to the right and to the left from 0 to 900, A
d) An axis connects the whole, the level can be integral, the whole is thus stable B
These four parts stand out on the drawing without possible error.

L'utilisation de l'angulomètre est très simple. A l'état statique, l'on a les aiguilles sur zéro qui nous donne le plan horizontal en conformité aveo le niveau. Les aiguilles mobiles fonctionnent en les réglant sur l'angulation voulue, le niveau étant en bonne position, il suffit de comparer l'inclinaison des dents à l'angle présenté pour modifier si necessaire celui-ci. The use of the angulometer is very simple. In the static state, we have the needles on zero which gives us the horizontal plane in conformity with the level. The movable needles work by adjusting them to the desired angulation, the level being in good position, it suffices to compare the inclination of the teeth to the angle presented to modify it if necessary.

Pour l'évaluation d'une angulation s il suffit d'appliquer les aiguilles sur les ouspides pour voir l'angle qu'elles décrivent lorsque l'on a le contact des cuspides vestibulaires et linguales avec le bord externe de l'aiguille. Le niveau étant toujours maintenu dans le-plan horizontal. For the evaluation of an angulation s it suffices to apply the needles on the ouspids to see the angle which they describe when one has the contact of the vestibular and lingual cusps with the external edge of the needle. The level is always maintained in the horizontal plane.

L'angulomètre a son application dans tous les laboratoires de prothb- se dentaire ainsi que dans les cabinets dentaires et écoles dentaires  The angulometer has its application in all dental prosthesis laboratories as well as in dental offices and dental schools
