The present invention relates to an articulation-navigation equipment for dental surgery which gets the relation between a patient'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'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's face using the face bow (not shown) in order to offer the prosthetic dentistry object. The main point for measuring the patient'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'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'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'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.
In addition, the dentist takes the relation between the patient'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's face and teeth.
As mentioned above, the face bow which is taken the relation between the patient'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'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'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'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'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.
