Title: Articulation navigation equipment for dental surgery

Description:
BACKGROUND OF THE INVENTION  
      The present invention relates to an articulation-navigation equipment for dental surgery which gets the relation between a patient&#39;s face and teeth using a face bow to offer the prosthetic dentistry thing for patients from dentist. It is desired the dentistry medical treatment is performed that the mouth which is observed using a face bow in dentist&#39;s position and the mouth which equips an occlusion machine and is observed in the position of the dental technician who manufactures a prosthetic dentistry object using the face bow gotten is carried out with the same concept. Specially, the present invention relates to an articulation-navigation equipment for dental surgery in spite of the face bow with the difficult operation and can offer the prosthetic dentistry object which is satisfied with aesthetic and functionally.  
      The conventional dentist measures the patient&#39;s face using the face bow (not shown) in order to offer the prosthetic dentistry object. The main point for measuring the patient&#39;s face is a median line M, a frankfult plane F, a camper plane C, a bite plane O and the like.  
      The face bow which is measured the patient&#39;s face is given to the dental technician which manufactures the prosthetic dentistry object. In this case, the face bow does not have the same concept between the mouth which is observed using a face bow in dentist&#39;s position and the mouth which is observed in the position of the dental technician who manufactures a prosthetic dentistry object. The skill was needed for the handling of the face bow until it resulted in the common concept. In addition, it is not the structure of the face bow which can measure the aesthetic point of patient&#39;s face. In spite of measuring completely in the physical distribution stage given the face bow taken from dentist to dental technician, the face bow is large, packing is complicated and screw etc. loosens so that it may be told for inaccurate information. When the prosthetic dentistry object is manufactured in the state that the inaccurate take is not noticed, since the manufactured prosthetic dentistry object does not suit for patient, it will start from measurement and taking of patient by dentist again.  
       FIG. 1  shows an example of the disclosed measuring for the patient&#39;s face. The dentist usually takes the relation between the patient&#39;s face and teeth using the face bow. In the disclosure of Japanese Patent Laid-Open Publication No. 10-295707, it is the example of take using the determination equipment of the esthetic bite plane. The reference numeral is explained, and unknown numeral is presumed. It is comprised of the face bow  1 , determination wire  5  for aesthetic bite plane, orbital support rod  6 , bite fork  7 , plate  8  for bite plane, both pupils  10 , median line rod  13  and attachment  14 . As shown in Figures, each parts of the determination equipment of the aesthetic bite plane as the face bow is arranged as covering the face so that it is impossible to observe the relation between face and teeth squarely.  
       FIG. 2  shows a perspective view showing the way in which a positioning device for aesthetic bite plane in  FIG. 1  is installed in a bite device. The dental technician installs the face bow transfer which takes the relation between the patient&#39;s face and teeth by the determination equipment for aesthetic bite plane in the bite device in order to manufacture the prosthetic dentistry object. The bite device which is installed the determination equipment for the aesthetic bite plane is observed squarely, it is comprised of the face bow  1  which is installed the bite device  12 , wire  5 , orbital support rod  6 , bite fork  7 , plate  8  for bite plane, both pupils  10 , median line rod  13  and attachment  14  so that each part of the determination equipment of the aesthetic bite plane as the face bow covers the bite plane, it is impossible to observe squarely and it is hard to manufacture the aesthetic prosthetic dentistry object.  
      In addition, the dentist takes the relation between the patient&#39;s face and teeth by various face bow which the skills is needed for handling. The dental technician who manufactures the prosthetic dentistry object using the face bow after taking, it is installed in the bite device with full adjustment or semi-adjustment. For the dental activity, it is desired that the oral cavity that is observed by dentist and by dental technician have equality on common concept. It is ideal that the model which is installed face bow taken the bite in the designated bite device is placed under the same situation. When the taken face bow is installed in the bite device and the dental technician manufactures the prosthetic dentistry object, since the measuring parts of the face bow aesthetic do not have such structure which shows the points of the face and they cover the face so that it is hard to observe, the dental technician manufactures the prosthetic dentistry object for the median line and tip part of central incisor through a trial and error process by the light of nature and experience based on the relation between patient&#39;s face and teeth.  
      As mentioned above, the face bow which is taken the relation between the patient&#39;s face and teeth by dentist is needed the skills. The measuring parts in the face bow cannot express the aesthetic point structurally, and it covers the front side of the face. Each face&#39;s point which is the base model cannot be observed in the disclosed determination equipment for the aesthetic bite plane squarely. It is difficult to observe the median line, frankfult plane and camper plane as necessary points on the face in the disclosed face bow and alternative measuring equipment. The bite plane is covered so that it is hard to observe because of the horseshoe-shaped bite fork. If right height of jaw is measured, right median line and tip of central incisor cannot be measured correctly. If it can be taken, the aesthetic point cannot be determined.  
      In addition, the oral cavity of patient is taken precisely for manufacture the denture base for patient by dentist. The biteplate is manufactured based on taking the detail impression. The biteplate is manufactured in order to manufacture the denture base, and the bite is taken. After that, the plaster cast is attached to the bite device. The dentist needs to decide the arrangement of maxillary front teeth by the tip of central incisor as based on the median line of the patient&#39;s face. Although the various types of equipment including the determination equipment for the position for the median line and arrangement axis for prosthetic tooth in order to support the arrangement of maxillary front teeth by dentist, the denture manufacturing equipment and the like are disclosed, they cannot arrange on the basis of patient&#39;s craniofacial anchoring point and relation of position for taking the bite. In this case, the positioning equipment for center position, the front teeth arrangement equipment for molding the prosthetic tooth, the arrangement equipment for molar teeth and the like are prepared, they are changed for any purpose so that they can manufacture with combining the ready-made parts uniformly, however there are many time to try to remanufacture the denture base in order to match the denture base to delicate feeling of patient and make patient feel more functional.  
      Accordingly, it is an object of the present invention to provide an articulation-navigation equipment for dental surgery which is a small size and lightweight. It is another object of the present invention to provide an articulation-navigation equipment for dental surgery that can operate quickly in a short time in spite of the face bow without practice and can measure and take the aesthetic point and basic point. It is still another object of the present invention to provide an articulation-navigation equipment for dental surgery that the dental technician who manufactures the prosthetic dentistry object can decide median line, right and left orbital, one of orbital, frankfult plane, camper plane and bite plane physically on the model that the taken articulation-navigation equipment for dental surgery is attached without covering by the measuring parts of the articulation-navigation equipment for dental surgery. It is still another object of the present invention to provide an articulation-navigation equipment for dental surgery that includes a bite fork which does not cover the bite plane and can decide the right median line from the position of the right and left central incisors. It is still another object of the present invention to provide an articulation-navigation equipment for dental surgery that can operate without changing the value of the take. It is still another object of the present invention to provide an articulation-navigation equipment for dental surgery that can manufacture the aesthetic and functional prosthetic dentistry object easily when the articulation-navigation equipment for dental surgery is attached to the bite device.  
      It is further object of the present invention to provide an articulation-navigation equipment for dental surgery that can arrange the maxillary front teeth-prosthetic tooth and maxillary molar teeth-prosthetic tooth from a theoretical standpoint on observing basic point with relation between the patient&#39;s head capsule and face, face, facial features and the like which is positioned by the articulation-navigation equipment for dental surgery and can manufacture the whole or partial aesthetic and functional denture base.

      Moreover, iron or stainless steel etc. which performed rust processing is used when lightweight is a main purpose. In order to hold and fix powerfully, the fixing base  20  may be magnetized using the material of the iron or nickel which carried out rust processing or cobalt which are a ferromagnetic substance.  
      In addition, for hospital infection prevention, the prosthetic tooth arrangement plate  431  for front teeth and bite plane plate  432  for molar teeth and prosthetic tooth are exchanged whenever the patient changes, and medical abandonment is performed.  
      As set forth above, the advantages of the invention are as follows:  
      (1) Since the present invention includes the measuring parts which take basically the relation between the patient&#39;s face and teeth are arranged; right and left bite fork which is bite in the oral cavity of the patient and fixes the bite plane; a positioning wire for camper, extending to right and left ears which measures and takes the camper plane C; an orbital pointing pin which measures and takes one of orbital; a pointing rod for median line which measures and takes the median line M; orbital points which measures and takes the right and left orbital on the frankfult plane F; pointing rod for bite plane which measures and takes the bite plane O; screw which is screwed on the nut for adjusting the height, supporting the support base; and screw for fixation. Therefore, it can operate quickly in a short time in spite of the face bow without practice and can manufacture the aesthetic and functional prosthetic dentistry object easily.  
      (2) As discussed above, the dental technician who manufactures the prosthetic dentistry object can decide median line, right and left orbital, one of orbital, frankfult plane, camper plane and bite plane physically on the model that the taken articulation-navigation equipment for dental surgery is attached without covering by the measuring parts of the articulation-navigation equipment for dental surgery. In addition, the support base can be removed so that it is easy to transfer.  
      (3) As discussed above, since the bite fork or bite spoon for patient can be changed t new one whenever the patient uses, the patient feel clean, and it can be prevented the hospital infection. In addition, the bite fork or bite spoon has a large size, middle size or small size corresponding to the size of the oral cavity so that the actual bite shape can be measured and taken.  
      Therefore, the articulation-navigation equipment for dental surgery is fixed to the fixing base and installed in the bite device so that it is easy to manufacture the aesthetic and functional prosthetic dentistry object.  
      (4) Claims  2  to  10  achieve the same effect of the above-mentioned (1) to (3).  
      (5) Claim  11  achieves the same effect of the above-mentioned (1) to (3), and the median line as the basis on the arrangement of the front teeth-prosthetic tooth by dentist is measured by the articulation-navigation equipment for dental surgery, and the bite plane is fixed by the bite plane pointing rod. Therefore, the median line is already determined and the front teeth arrangement plate for prosthetic tooth is only changed. The front teeth arrangement plate includes a suitable inclination which three teeth as front teeth-prosthetic tooth of the upper jaw can be adhered by a wax centering around the patient&#39;s median line, having a curvature part corresponding to the curvature of the patient&#39;s front teeth of the upper jaw so that the front teeth arrangement plate for prosthetic tooth passes through the bite plane holding part and is fixed by the screw, and the center position of the arrangement of the front teeth-prosthetic tooth is already determined. Therefore, the front teeth arrangement plate attaches to the curvature part of the front teeth for the arrangement of the front teeth-prosthetic tooth, and the dentist or dental technician can work to arrange the bite with considering the size, color and material of the prosthetic tooth and decide to arrange the suitable front teeth-prosthetic tooth by the facial features of the patient.  
      (6) As discussed above (5), the front teeth arrangement plate is formed with the large size (L), middle size (m) and small size (S) so as to correspond to the curvature portion of the patient&#39;s front teeth so that dentist or dental technician can be chosen the suitable size for the arrangement of the patient&#39;s front teeth prosthetic tooth, and it can be improved to provide medical care efficiently.  
      (7) Claim  12  achieves the same effect of the above-mentioned (1) to (3), and the dentist or dental technician can work to arrange the bite with considering the size, color and material of the prosthetic tooth when the arrangement of the molar teeth-prosthetic tooth of the upper jaw is determined on the basis of the prosthetic arrangement for the front teeth of the upper jaw decided by front teeth arrangement plate after the bite plane plate with the articulation-navigation equipment is installed in the fixing base. Therefore, it can be operated in a short time n the best condition.  
      (8) As discussed above (7), the bite plane for the molar teeth-prosthetic tooth is formed with the large size (L), middle size (m) and small size (S) so as to correspond to the curvature portion of the patient&#39;s front teeth so that dentist or dental technician can be chosen the suitable size for the arrangement of the patient&#39;s front teeth prosthetic tooth, and it can be improved to provide medical care efficiently.
