The aim of this face bow and protraction headgear design is to correct the anterior open bite in dentally Class III open bite cases. Patients were selected and full coverage acrylic cap splint-type rapid maxillary expansion appliance was cemented and activated twice a day for 5 days. After sutural separation, newly developed face bow and protraction headgear was worn and 750 g of force was applied. Newly developed appliance consisted of a face bow and forehead pad. The face bow had intraoral and extraoral components and was custom made individually for each patient. The intraoral bow was inserted from the distal openings of the tubes which was soldered to the extraoral face bow. The extraoral face bow was extended backward till the front of the ear then turned upward and ended at the level of the hooks on the forehead pad. In this extraoral appliance design only the forehead was used as anchorage unit. On both sides of the pad, adjustable wire hooks were placed which allowed us to maintain the distance from the forehead pad hooks to the face bow hooks. Heavy elastics were attached in between the hooks of the face bow and the hooks on the forehead pad.

It is intended to provide an occludator whereby joint movements at occlusion being similar to the actual tempromandibular joint movements of an individual patient or ideal movements can be reproduced, and a face bow to be used for the occludator. To achieve this object, an occlusion plane against a standard plane is accurately drawn by using the above face bow F whereby the occlusion plane can be drawn at a high accuracy. A solid model of the tempromandibular joint similar to the tempromandibular joint form of an actual patient is used as the joint unit of the occludator K, while the positional relationship in the body at occlusion is three-dimensionally reproduced in the occludator I with the use of the above-described face bow F. It is also intended to provide an occlusion-confirming system and a tempromandibular joint-reproducing system with the use of an occludator whereby joint movements at occlusion being similar to the actual tempromandibular joint movements of an individual patient or ideal movements can be reproduced. To achieve this object, the tempromandibular joint of the body is photographed with a local X-ray CT device to give three-dimensional image data and then a solid model of the tempromandibular joint is constructed based on the three-dimensional image data. This solid model is employed as the joint unit of the occludator K and the positional relationship in the body at occlusion is three-dimensionally reproduced.

A dental face bow suitably used for odontotherapy against edentulous jaw disease and multi-tooth coloboma, comprising a base frame having a pair of right and left side-frames along both side parts of the head part of a sufferer and a laterally extending lateral frame connecting the pair of right and left side-frames to each other and a rotating frame rotatably supported on the base frame so as to be moved close to and apart from the face of the sufferer on the inside of the side-frames. A mouthpiece inserted into the oral cavity of the sufferer is fitted to the lateral center part of the rotating frame. Ear pieces locked near the right and left earholes of the sufferer and a reference point indicator indicating the occlusal force concentrated part which is set near the nasion of the sufferer are fitted to the rotating frame.
