Measuring device for dentistry and use procedure
5 Object of the invention
The object of the present invention is a manual device and its method of use, which allows repetitive measurements of the lower third of the face to be obtained to obtain the vertical dimension and the nasolabial and nasogenian angles, which are necessary to make plans
10 correct treatment in prostheses, aesthetics and orthognathic surgery.
Background of the invention
At present the measurement of vertical dimensions and angles of the third
15 lower and middle of the face is done manually, the first thing is to make two marks with a marker on the patient's face, one on the chin and the other on the tip of the nose, and then using a compass, which later It moves to a ruler, and an angle conveyor perform measurements depending on the different positions of the jaws.
20 Other methods of taking measurements are the use of radiographs or computer systems that perform a three-dimensional scan of the patient's face.
The first method has the disadvantage that the reference points are arbitrary and hardly repeatable, so that the measures taken during a visit are not the same as
25 those taken on the next visit, so you have to repeat the whole process. In the other methods the disadvantages are the complexity, the cost of the equipment and the radiation exposure whenever it is necessary to repeat the measurements.
The invention described below consists of a simple manual and cost device
30 reduced, which allows the taking of measures referring to fixed points of the skull with projection on the patient's skin and therefore repeatable, which allows not having to take measures continuously and transmit the information as a quantifiable data and with a high degree of accuracy . Description of the invention

The measuring device for dentistry, object of the present invention, is one of those comprising a slide capable of moving longitudinally along a bar, whose length is approximately equal to the length of the slide, in which a scale is arranged graduated, comprising:
5  first means of blocking at will of the movement of the slide;
 a first plate coupled by means of first articular joint means to the end of the bar closest to zero of the graduated scale and arranged such that the side of said first plate that is coupled to the bar is perpendicular to the longitudinal axis of the referred bar;
10  a second plate, which is arranged in the opposite direction to said first plate, coupled by means of second articular joint means to the end of the slide closer to zero of the graduated scale and arranged in such a way that the side of said second plate that is coupled to the slide is perpendicular to the longitudinal axis of said bar;
15 and because the first and second articular joining means have locking means at will of their respective positions.

Preferred embodiment
25 Figures 1 and 2 show two different perspectives of the measuring device for dentistry (1), which are those comprising a slide (2) suitable for moving longitudinally along a bar (3), whose length is approximately equal to the length of the slide (2), that is, similar to a king's foot. In the referred bar is arranged
30 a graduated scale.
The measuring device for dentistry comprises:  first locking means (4) at the will of the movement of the slide;
35

 a first plate (5) coupled by means of first articular joint means (6), for example, hinge type, to the end of the bar (3) closest to zero of the graduated scale and arranged in such a way that the side of said first plate that is coupled to the bar is perpendicular to the axis
5 longitudinal of said bar;
 a second plate (7), which is arranged in the opposite direction to said first plate (5), coupled by means of second articular joint means (8), for example, hinge type, to the end of the slide (2) more close to zero of the graduated scale and arranged in such a way that the side
10 of said second plate (7) that is coupled to the slide (2) is perpendicular to the longitudinal axis of said bar (3).
The first and second articular joint means (6, 8) have locking means (9) at their respective positions, for example, a pressure screw.
15 As a design option, the invention may have an electronic device, provided with a data display screen, suitable for displaying the measurement taken, and to facilitate the taking of angle measurements the first and second articular joint means can have, each of them, a graduated scale of angles.
20 The procedure for using the measuring device for dentistry, described above, for obtaining the vertical dimensions of the lower third of the face comprises the following steps:
to. the first and second plates are arranged perpendicular to the bar and the slide 25 respectively
b. the first plate is located at the base of the nose obtaining the reference position for the measurements or zero
C. The second plate is located at the base of the chin obtaining the desired vertical dimension.
30
Through this procedure the following measures can be obtained:
 the vertical resting dimension, which is the height of the lower third of the face, with the lower jaw suspended in a tone position, that is to say without dental contact, lips together without tension and held in relaxation by the opening and closing musculature
35 compensated. This vertical measurement is stable in the patient throughout his life. This resting position is comfortable and is usually maintained. 4

 the vertical dimension of occlusion, which is the height of the lower third of the face with the teeth in contact, maximum intercuspidation. If the patient is edentulous, the vertical dimension of occlusion will be measured with wax rollers that maintain the relationship
 the vertical tone dimension of the lower third of the face corresponds to an opening
5 buccal compensated by the passive action of the opening and closing musculature of the oral system, without dental contact, which is typical of a state of maximum relaxation or deep sleep.
 maximum opening dimension, which is the length of the lower third of the face when the patient opens the muzzle to the maximum, and even forcing the opening by the explorer. 10 This measure may provide information on the existence of ligamentous hyperlaxities and
Other pathologies
 The interocclusal free space, that the difference between the vertical dimension of rest and the occlusion, is a physiologically necessary space for the rest of the musculature that varies between 2 and 5 mm.
15 The method of using the device for measuring the overhang and overbite, horizontal distance between the incisors, comprises the following steps
to. the lower end of the bar rests on the lower end of the upper incisor teeth
20 b. the slide slides until its lower end contacts the lower incisive teeth.
The procedure for using the measuring device for dentistry for the measurement of the nasolabial angle comprises the following steps:
25 a. the first tangent plate is placed at the base of the nose
b. the tangent bar is arranged at the upper lip inclination
which allows to study the influence of the position of the upper lip and its corresponding angle on the patient's profile and the possibility of anticipating the variation of the profile of the
30 patients, according to the treatment plan chosen to solve the patient's pathology.
As an option in the procedure, the bar can be arranged tangent to the chin, whereby we obtain the angle between the anterior nasal spine and the anterior projection of the most advanced point of the lower jaw. The value of the referred angle allows us to classify the patient
35 according to the Angle Classification.

The dimensions allowed to take the measuring device for dentistry, allow professionals to discern whether the patient can be treated with conventional treatments
or requires more drastic treatments such as orthognathic surgery in combination with orthodontics and prostheses.
5
The use of the measuring device for dentistry is not subject to the skill or subjectivity of the dentist because it uses fixed anatomical points, therefore, any professional who studies the clinical history can repeat the measurement obtaining the same data. In the case of variation of the measures its origin may be studied. After a treatment they will have
10 to take the measures again and record them in the medical record.
