Definitions

  • ABSTRACT A method to determine the correct depth of the lingual rim of a bite plate during the construction of a denture for a toothless mandible, or to check the correctness of the depth of the lingual rim of a lower denture.
  • the distance is measured between the occlusal surface of the wax rim or the bite plate on the level of the incisal edges of the teeth of the lower denture, on the one side, and the highest point of the inner surface of the bite plate or of the lower denture, which covers in situ the anterior part of the jaw ridge of the mandible, on the other side, whereafter a plate-shaped registering element with a height substantially equal to said distance is positioned vertically on the anterior part of said jaw ridge and the extension rate of the tongue is measured and compared with its extension rate after the bite plate or the lower denture has been positioned in situ.
  • This plate-shaped registering element comprises a flat lower supporting face and an upper face in parallel therewith, said element being bent about an axis which extends perpendicularly to said faces in the median plane of the registering element.
  • the invention relates to a method to determine the correct depth of the lingual rim of a bite plate during the construction of a denture for a toothless mandible, or to check the correctness of the depth of the lingual rim of a lower denture: as well as to a plate-shaped registering element adapted to be used in this method.
  • the functional spectrum or operating area of the muscles of the tongue and of the floor of the mouth that is to say the contraction range of the tongue between zero (wherein the tongue extends somewhat below its rest position) and maximum (wherein the tongue is, e.g., extended at its maximum), will be reduced.
  • the method according to the invention is characterized in that the distance is measured between the occlusal surface of the wax rim on the bite plate or the level of the incisal edges of the teeth of the lower denture, on the one side, and the highest point of the inner surface of the bite plate or of the lower denture, which covers in situ the anterior part of the jaw ridge of the mandible, on the other side, whereafter a plate-shaped registering element with a height substantially equal to said distance is positioned vertically on the anterior part of said jaw ridge and the extension rate of the tongue is measured and compared with its extension rate after the bite plate or the lower denture has been positioned in situ.
  • a comparative test measurement is made, wherein the tongue, during its extension, is forced to transgress the anterior part of the lower jaw ridge at a level which corresponds with the level of the occlusal surface of the wax rim on the bite plate or with the level of the incisal edges of the teeth of the lower denture in order to obtain an exact registration of the maximum extension rate of the tongue of the patient, while preventing any interference by the lingual rim.
  • the extension rate of the tongue is equal to this rate registered after the bite plate or the lower denture is positioned in situ in the mouth of the patient, it is certain that the lingual rim has no excessive depth and that the functional spectrum of the muscles of the tongue and of the floor of the mouth has not been decreased. If, further, a sufficient suction effect has been obtained, it is certain that the lingual rim of the bite plate or the lingual rim of the lower denture has the correct depth.
  • FIG. 1 is a top view of an embodiment of the registeringinstrument according to the invention.
  • FIG. 2 is a front view of the registering instrument according to FIG. 1.
  • FIG. 3 is a section along the line III-III in FIG. 1 at a larger scale.
  • the registering instrument according to the invention as shown in the drawings serves for determining the correct depth of the lingual rim of a bite plate during the construction of a denture for a toothless mandible, or for checking the correctness of the depth of the lingual rim of a lower denture.
  • This registering instrument comprises a plate-shaped registering element 1 with a flat lower supporting face 2 and with an upper face 3 which runs parallel to this lower supporting face 2.
  • the registering element 1 is bent about an axis which is perpendicular to the lower supporting face 2 and the upper face 3 in the median plane of the registering element 1.
  • the radius of the registering element 1 approximately corresponds with the radius of the anterior part of the lower jaw ridge of the patient.
  • the width of the registering element 1 decreases in the downward direction.
  • the registering element 1 is provided with two detachable handles 4.
  • the registering element 1 comprises on both sides an upwardly directed projection 5 which is square in cross-section and which is inserted in a hole 6 in an end portion 7 of the handle 4 concerned.
  • Each end portion 7 is connected to the grip 9 proper via a hookshaped outwardly and downwardly extending intermediate portion 8.
  • the inner edge of the grip 9 has to run approximately parallel to the check of the patient at an interspace of 1-2 cm.
  • Each projection comprises a recess 10, which engages a ball 11, which is received in a hole 12 in the cooperating end portion 7 of the handle 4 and is springbiased by a spring 13. In this manner each handle 4 is attached on the projection 5 concerned.
  • a registering element 1 is chosen from a set of registering elements, namely the registering element 1, wherein the distance between the lower supporting face 2 and the upper face 3 is approximately 1 mm shorter than the distance between the highest point of the inner surface of the bite plate or the denture, which covers in situ the anterior part of the lower jaw ridge, on the one side, and the occlusal surface of the wax rim on the bite plate or the level of the incisal edges of the anterior teeth on the lower denture, on the other side. This latter distance is measured by means of an especially adapted sliding gauge.
  • a layer 14 of sponge rubber or the like soft material is glued on the lower supporting face 2.
  • the height of this layer 14 amounts to approximately 1 mm in the compressed working position so that the total height of the registering element 1 together with its layer 14 substantially equals the above mentioned distance measured on the bite plate or on the lower denture.
  • the registering element 1 is positioned in the mouth of the patient so that the layer 14 rests on the lower jaw ridge.
  • the layer 14 will eliminate the influence of these irregularities, while on the other hand any damage of the mucosa on the ridge is effectively prevented.
  • the registering element 1 is kept in a vertical position by means of the handles 4 which extend outside the mouth.
  • the position of the registering element 1 is such, that the inner or tongue-side surface of this re gistering element 1 extends approximately vertically above the base of insertion of the musculus genio glossus.
  • the tongue of the patient is extended as far as possible and the extension rate of the tongue is measured.
  • the bite plate or the lower denture is put in situ, whereafter the patient again extends the tongue as far as possible. If the extension rate measured in this latter case corresponds with the extension rate measured during the presence of the registering element 1 in the mouth, it is certain that the lingual rim of the bite plate or of the lower denture does not interfere with the functional spectrum of the muscles of the tongue and of the floor of the mouth. When further a sufficient suction effect has been ascertained, the certainty has been obtained that the lingual rim of the bite plate or of the lower denture has the correct depth in the anterior part of the floor of the mouth.
  • handles 4 are mounted in a detachable manner it is sufficient to provide only one set of handles 4 for each set of registering elements 1.
  • the registering elements 1 and the handles 4 together form a set of instruments which can be indicated as a linguo-spectograph.
  • the registering elements 1 and the handles 4 are shaped in such a way that they do not deform the lower lip of the patient when the registering element 1 is positioned in the mouth.
  • An element as claimed in claim 1, comprising a resilient layer adhesively fastened to the lower surface of said plate member, the bottom surface of said resilient layer forming the element surface being supported on said jaw ridge.
  • each of said handle means having an aperture adjacent one end thereof for receiving said upwardly projecting portion, and including a hand grip portion connected to said end portion by a hook-shaped outwardly and downwardly extending intermediate portion.
  • An element as claimed in claim 1, comprising a plurality of said plate members adapted to be interchangeably positioned in the mouth of a patient, the vertical height between the upper and lower surfaces of said plate members being gradually increased of from approximately 5 mm to approximately 15 mm.
  • a method to determine the correct depth of the lingual rim of a bite plate during the construction of a denture for a toothless mandible comprising measuring the distance between the occlusal surface of a wax rim on the lingual rim of the bite plate and the highest point of the inner surface of the bite plate, which covers in situ the anterior part of the jaw ridge of the mandible, positioning a plate-shaped registering element having a height substantially equal to said distance vertically on the anterior part of said jaw ridge, and measuring and comparing the extension rate of the tongue with the extension rate of said element after the bite plate has been positioned in situ.
