Definitions

  • the invention relates to lip and cheek expanders for use when performing dental medicine, dental hygiene or dental-documenting activities according to the preamble of claim 1.
  • Such retractors which are usually made of metal, are suitable exclusively for freeing up one side of a working space.
  • cheek retractors designed in various ways are necessary for the retraction to be effective.
  • mouth mirror, cheek retractor and retractor hook must be guided by hand.
  • an assistant is needed in addition to hold the retractor.
  • the restricted working space requires a precisely co-ordinated interplay of the movements of the person performing the treatment and the assistant.
  • even the most skilled assistant cannot succeed in keeping away or retracting the sensitive lips, corners of the mouth and cheeks to the complete satisfaction of the patient and of the person performing the treatment.
  • Spreader clamps are also known in which pre-formed lip shields and a spreading apparatus rigidly connected to the latter are formed by a single plastic injection-molded part. Unlike the previously mentioned metal instruments they do permit a somewhat gentler retraction on the one hand, but on the other hand a sterilization is possible only to a limited extent, as plastics that can be used for this purpose are generally not autoclavable. However, if sterilization is insufficient, herpes labialis for example, which frequently occurs on the lips and corners of the mouth, is easily transmissible.
  • a protective body with a pre-formed U-shaped longitudinal profile which is made from a soft, elastic material, is known from DE 83 23 817 U1. If one of the lips is inserted into this U-shaped protective body, it is actively protected by the protective body against injuries caused by the treatment tools. This protection can be further increased by additionally incorporating into the U-shaped protective body reinforcements made of special steel wire.
  • One embodiment of the invention ensures that the mouth opening is kept open, but not that the lips are kept away from the rows of teeth.
  • a further embodiment is disclosed which is characterized by a metal spacer bracket additionally attached to the protective body. This spacer bracket, which can be supported against the row of teeth lying behind the protected lip, ensures the desired distance between the lip and the row of teeth.
  • painful pressure marks are usually caused by this type of support.
  • the object of the invention is therefore to remedy defects of the state of the art.
  • a lip and cheek expander is to be proposed which is versatile in use and may be produced at low cost, and also simultaneously keeps away and protects the lips and cheeks coming to rest against the rows of teeth.
  • tensioning frames are to be understood in the broadest sense as spatial structures which can absorb pull forces of a pre-determined order of magnitude directed against the centre of the structure.
  • tensioning frames can be constructed to be rigid or elastic, optionally plastically deformable in addition.
  • Elastically constructed tensioning frames facilitate among other things the application of an expander according to the invention. They can be made for example from wire, from solid profiles, small tubes or other suitable hollow profiles, or consist of metal alloys, of plastics., of rubber or of composite materials.
  • a tensioning frame can also consist of several parts which are joined together. At least one of these frame parts can be attachable to a saliva suction device and can be constructed as a small tube provided with holes.
  • the tensioning frames are usually constructed as closed tensioning frames.
  • open tensioning frames are also possible and can be of advantage for special purposes.
  • Open tensioning frames must be constructed to be more solid than closed tensioning frames in order to be able to withstand the loadings that occur when the expander is fitted.
  • tensioning frames in particular in the two areas of the corners of the mouth, are constructed larger than the oral cavity, an expander according to the invention can effectively be prevented from slipping out or in. It is also conceivable to construct tensioning frames, in particular tensioning frames resting externally against the mouth opening, in an adjustable manner.
  • film-like means When reference is made in connection with the invention to film-like means, these are to be understood in the broadest sense as sheet objects which essentially offer no resistance to bending as compared to stretching.
  • the film-like means can be made from elastically stretchable, but in principle also from non-stretchable, material.
  • lip and cheek expanders according to the invention a pressure force is exerted, distributed over a large area, via the film-like means on the lips and cheeks which are to be held back from the rows of teeth.
  • the film-like means are connected at one end to an inner tensioning frame located inside the oral cavity and at the other end to an outer tensioning frame resting externally against the lips and cheeks.
  • the film-like means are advantageously constructed to be thin and elastic.
  • elastic, optionally pre-bent tensioning frames adapted to the anatomical conditions, very simple, extremely flexible and widely usable lip and cheek expanders can be provided which offer many advantages compared with conventional retractors and spreader clamps.
  • the patient's wearing comfort can be further increased or other advantageous effects can be achieved by the application of the expander according to the invention.
  • the tissue dynamic is also essentially maintained when the expander is fitted.
  • an additional retraction with a retractor hook or the mouth mirror is possible at any time.

  • FIG. 7 an enlarged view of the vicinity VII of the tensioning frames of the lip and cheek expander of FIG. 2, and
  • FIG. 8 the film-like means prior to connection to the two tensioning frames.
  • FIGS. 1 and 2 show an embodiment of a lip and cheek expander according to the invention when not fitted.
  • This expander comprises two tensioning frames 1 and 2 which are constructed annularly closed, and film-like means 3 connecting the two tensioning frames 1 and 2 .
  • the means are constructed closed in the form of a circumferentially extending thin membrane.
  • the tensioning frames 1 and 2 have the shape of differently sized, arched ellipses. They are constructed elastically bendable and can be made for example from a circumferentially extending special steel wire.
  • One of the tensioning frames which according to FIG. 3 is arranged inside the oral cavity, the inner tensioning frame 1 , has greater dimensions than the outer tensioning frame 2 .
  • the inner tensioning frame 1 is connected to the outer tensioning frame 2 via the film-like means 3 .
  • the tensioning membrane in a non-fitted state corresponding to FIG. 1, lacks a pre-determined shape and is tension-free. It is designed in the form of a thin, easily stretchable film and consists for example of elastic latex.
  • the inner tensioning frame 1 and the outer tensioning frame 2 are fixedly connected via an adhesive to the tensioning membrane over their full surface.
  • the two tensioning frames 1 and 2 can also be wound round several times by the film. In this way the relatively small bearing surface of the metal tensioning frames 1 and 2 is greatly increased and made softer by means of the additional film material. The expander can thereby be made even more comfortable to wear.
  • FIG. 3 shows in front view the mouth opening of a person to whom the expander from FIGS. 1 and 2 is fitted.
  • the inner tensioning frame 1 is indicated in FIG. 4 by broken lines.
  • the tensioning membrane rests against the lips and the adjacent cheek areas and uniformly exerts a pressure force in an areally distributed manner. Due to the elastic design of the film-like means 3 as well as to a certain elastic flexibility of the inner tensioning frame 1 and the outer tensioning frame 2 , respectively, the pressure force can be distributed essentially uniformly in combination with a co-ordinated dimensioning of these three components. In this way a uniform expansion of the lips and cheeks can also be achieved.
  • the inner tensioning frame 1 has greater dimensions than the outer tensioning frame 2 , the parts of the cheeks lying between the tensioning frames are tilted somewhat forward in the area of the small azimuths of the ellipses. In this way the cheeks are additionally kept even further away from the rows of teeth.
  • the respective distance between the cheek and the rows of teeth can also be increased by a suitable shape of the inner tensioning frame 1 , for example by additional, shield-like bulges in the area of the small azimuths of the ellipse.
  • the inner tensioning frame 1 Due to the dimensioning of the membrane, in this embodiment, in the area of the large azimuths of the ellipses, the inner tensioning frame 1 is located closer to the mouth opening than the outer tensioning frame 2 . As a result, the inner tensioning frame 1 comes into contact with neither the lip frenulums nor the cheek frenulums. However, this could also be achieved by suitably pre-bent indentations of the inner tensioning frame.
  • the present invention makes possible on the one hand good access through the mouth opening and on the other hand the avoidance of painful pressure marks, even when an expander according to the invention is fitted for several hours.
  • an elastic construction of the components of the expander optionally in combination with a manual plastic deformation of the tensioning frames, individually different anatomical conditions can normally be well compensated for.
  • account can also be taken of these different conditions or special requirements as regards the distance between individual parts of the lips and cheeks and the rows of teeth, such as may be necessary in some treatments, by the use of suitably designed tensioning frames and membranes.
  • Different types of expanders could be identified by different colours.
  • FIG. 4 shows a section through the expander and the mouth opening of FIG. 3. Contrary to FIG. 3, the inner tensioning frame 1 and the outer tensioning frame 2 are visible. In the area of the mouth opening the film-like means 3 lie snugly against the lips 4 . Uniform pressure forces 5 are exerted, areally distributed, on the lips 4 via the tensioning membrane. They counteract the closure and contraction forces of the lip and cheek muscles and bulge-likely compress the lips 4 —starting from the normal position of the lips indicated by dots. Circumferential pulling forces 6 and 7 corresponding to the pressure forces 5 are exerted by the tensioning membrane on the inner tensioning frame 1 and the outer tensioning frame 2 , respectively.
  • the pulling forces 6 and 7 can be absorbed virtually completely by these in the area shown. In this way, in this area the inner tensioning frame 1 exerts no contact forces on the respective mucous membrane of the lips. In other areas, on the other hand, only parts of the pulling forces 6 and 7 are absorbed by the tensioning frames 1 and 2 , respectively. The resulting contact forces effect a corresponding abutment of the tensioning frames 1 and 2 .
  • the expander is kept stable by the equilibrium of the forces establishing around the mouth opening.
  • the second tensioning frame 1 together with a part of the film-like means 3 is introduced into the patient's mouth and the first tensioning frame 2 placed around the mouth against the perioral areas of the face.
  • the second tensioning frame 1 is elastically compressed in such a way that it can be inserted into the vestibule 13 .
  • the second tensioning frame 1 due to its elasticity, presses itself into the vestibule 13 , as a result of which it pulls the film-like means 3 in the upper jaw and in the lower jaw along the vestibule 13 into the latter and retains it therein.
  • the film-like means 3 is stretched. It can be seen from FIGS. 3 and 4 as well as from FIG. 6, which shows a view of the lower jaw after the insertion of the lip and cheek expander into the mouth, that the film-like means 3 extends from the tensioning frame 2 resting against the face along the skin of the face around the corners of the mouth and the lips 4 and intraorally in the vestibule 13 . In this way lips and corners of the mouth are covered, so that the film-like means 3 represents a covering means. As described further above, the tensioning ring 2 clamped into the vestibule 13 , together with the covering means 3 , pushes apart upper and lower jaws vertically and corners of the mouth transversally. FIG.
  • FIG. 5 shows a view of the lower jaw prior to the insertion of the lip and cheek expander into the oral cavity of a patient.
  • the comparison between FIGS. 5 and 6 illustrates the retraction, effected by the lip and cheek expander, of the lips 4 , the corners of the mouth and the cheeks 9 from the row of teeth 8 and the expansion thereby achieved of the vestibule 13 , which creates an enlarged working space for the dentist.
  • the tensioning frames 1 , 2 can, as already described, also be constructed to be open. In this case they are preferably connectable in such a way that, in this manner, they can be brought into an annularly closed form.
  • the tensioning frames can have a large variety of different shapes. Thus it may be that the tensioning frames 1 , 2 have an essentially elliptical basic shape or can be brought into an essentially elliptical basic shape.
  • the tensioning frames 1 , 2 can however also have a circular shape or be able to be brought into a circular shape, the second tensioning frame 1 having a smaller outer diameter than the first tensioning frame 2 .
  • the outer diameter of the tensioning frames 1 , 2 in the circular shape is advantageously 40 mm to 120 mm, and preferably about 75 mm for the second tensioning. frame 1 and preferably about 95 mm for the first tensioning frame 2 .
  • FIG. 7 shows in an enlarged representation a section of one of the two tensioning frames 1 , 2 and of the adjacent covering means 3 connected to the latter.
  • the two end portions of the covering means 3 along which the tensioning frames 1 , 2 are disposed, are each rolled up in a direction extending essentially perpendicular to the tensioning frames 1 , 2 to form a bulge 10 .
  • the end portions 10 formed in the manner of a bulge, of the covering means 3 are constructed not to be unrollable, e.g. by using an adhesive or by sealing.
  • the bulge-like end portions 10 of the covering means are each arranged at the inside of a tensioning frame 1 , 2 , wherein the bulge 10 may be adhesively connected to the tensioning frame 1 , 2 .
  • the part of the covering means 3 extending from the bulge 10 is then preferably passed at least once around the tensioning frame 1 , 2 , so that the covering means 3 completely surrounds the tensioning frame 1 , 2 .
  • the covering means 3 can serve as a pressure pad with which at least the second tensioning frame 1 or else also both tensioning frames 1 , 2 are advantageously provided and which extends along the tensioning frames 1 , 2 .
  • a separate pressure pad 14 such as is shown in FIG. 7 and with which at least the second tensioning frame 1 is provided and which extends along the respective tensioning frame 1 , 2 .
  • this pressure pad 14 extends along the entire tensioning frame 1 , 2 in question or else along one or more sections of the respective tensioning frame 1 , 2 .
  • the pressure pad 14 preferably surrounds the respective tensioning frame 1 , 2 and the bulge-like end portion 10 , connected to the latter, of the covering means 3 and consists of a soft material which is advantageously foam.
  • FIG. 8 shows the covering means 3 prior to the connection to the two tensioning frames 1 , 2 .
  • the covering means 3 can have strip-shaped open or else a ring-shaped and thus tubularly closed design. It has two end portions 11 , 12 along which the covering means 3 is connected to the tensioning frames 1 , 2 , which preferably is effected by winding these sections 11 , 12 around the tensioning frames 1 , 2 .
  • the dimensions of the covering means are preferably chosen such that they are about 30 mm along the line A-A which identifies the portion to be arranged in the area of the lower incisors, about 35 mm along the line B-B which identifies portions to be arranged in the area of the corners of the mouth, and about 25 mm along the line C-C which identifies the portion to be arranged in the area of the upper incisors.
  • the covering means 3 can be produced in standard sizes, for example for children and for adults.
