Definitions

  • the inclination of the occlusal plane is related to the state of health or disease of the chewing apparatus of a subject; also, as described by Karkazis and Polyzois (J Prosthet Dent, 1991; 65, 258- 64) the inclination of the guard occlusal plane relative to the aesthetics and function of the removable prosthesis.
  • this technique is invasive, that is, it causes damage to the patient / subject, since ionizing radiation is always harmful to the human organism, to a greater or lesser extent;
  • diagnosis needs to be deferred, until obtaining teleradiographs, so that we must assess the results by means of visualization techniques of the radiographic plates;
  • it only gives approximate average information of the two occlusal planes simultaneously, not individualizing each side, which may have different inclinations in the same subject or patient.
  • the invention that we present consists of a device and a method of using it, allow to determine the inclination of the occlusal plane of the teeth of the subject / patient overcoming the inconveniences posed by the techniques and methods described above in the sense of reducing times and costs necessary to obtain the values of the angle of the occlusal plane eliminating the risks derived from the radiation and / or avoiding annoying, expensive maneuvers and that require to invest time. It is also an easy instrument to build and cheap. The technique is very simple for an average professional and easy to apply.
  • the device gauge of the occlusal plane, consists of a "U" shaped instrument of rigid material, in which both branches are different in shape and length, as can be seen in Fig. 1.
  • the branch of smaller length, intrabuccal branch (RI) is equipped with two movable and fixed supports that can slide along it, the rear support SP
  • intrabuccal branch RI has another anterior support SA (because it is introduced and placed in the mouth in the anterior part) is internal to the intrabucal branch RI of the gauge; this sliding support SA to adapt to the individual length of the dental arches, is placed on the dental surfaces of the teeth of the upper jaw; that is, the SP on the second molar, or another posterior tooth.
  • SA will move without changing its direction, which will be rectilinear, maintaining the same situation with respect to the internal branch, without turning, to support it on an anterior tooth, such as the canine or the first premolar preferably, when they exist.
  • the former is, generally, cusp of the canine ahead; the posterior, the final second or first molar (or temporary second molar), always on the same side, that define the occlusal plane.
  • the movable and sliding supports SA and SP have the shape described in figure 2, which allows to be placed on the surface of the teeth in a stable way.
  • the height of the supports will be 16 mm high, 6 mm wide and 5 mm thick, they will be fixed by means of a screw or stop on the axis of the RI branch.
  • As the internal branch will have a thickness of 3 mm approx. in the caudal skull direction, in the measuring position on the subject, the SA and SP supports protrude from the surface of this branch about 5 mm.
  • the mobile and sliding supports SA and SP are placed on the surface of the teeth stably.
  • the other branch of the device extrabuccal branch (RE), of polygonal section, attached to the intrabuccal and parallel to each other, allows to visualize from the outside (by parallelism), the inclination that the RI branch adopts.
  • This RE allows to measure the inclination of the occlusal plane, regarding points and / or external cranial lines, such as the Frankfort or Camper planes (GPT-6, reference cited in the DESCRIPTION of the first page of this report), which may be marked on the subject's skin with respect to or on some material covering the skin of this area; the rectilinear edges of the polygonal section of this branch RE, allow to measure the inclination of this one, with respect to external anatomical points, with better visual performance than if it were rounded.
  • GPS-6 Frankfort or Camper planes
  • Fig. 3 shows the procedure for using the device described.
  • Method of implementation using a rigid material such as stainless steel, plastic, biomaterials, that is, any material used in dental or engineering clinics, a "U” is configured (Fig. 1).
  • the internal IR is provided with two supports or supports (fig. 2) that can be regulated and fixed at different distances from each other, so that they coincide with the cusps or surfaces of the teeth or prostheses of the subject being studied (Fig. 3).
  • the separation between the two supports may range between 1 cm and up to 7 cm, approximately the maximum length of the dental arch.
  • the thinner outer branch (0.5 cm in length of the side of the section approximately, will be of polygonal type section, so that the lines of the edges allow to see clearly and rectilinearly the direction of these and compare them with Camper's facial planes or Frankfort (Fig. 3).

Abstract

Le dispositif, a savoir une jauge du plan d'occlusion, en forme de U, possède deux branches différentes: la plus courte (branche intrabuccale), avec deux supports mobiles coulissants, s'introduit dans la bouche en faisant porter les supports en deux points des surfaces dentaires supérieures d'occlusion et/ou incision qui définissent ce plan; l'autre branche (branche extrabuccale), parallèle à l'antérieure, permet de visualiser de l'extérieur l'inclinaison adoptée par la branche interne de la jauge et, par conséquent, l'angle du plan d'occlusion par rapport aux plans faciaux de Frankfort ou de Camper. Application à des sujets normaux et à des patients en stomatologie dans des cliniques d'odontologie-stomatologie, en médecine chirurgicale et en sciences biologiques en général.
