Description

Quarter-arc full-dentition maxillofacial lighting angle retractor

Technical Field

The utility model belongs to the technical field of oral medical instrument, especially relate to a full dentition jaw face of quarter arc shines oral angle drag hook.

Background

The oral photography can record the clinical case data vividly, objectively and comprehensively, and the perfect picture data not only provides a foundation for doctors to diagnose, draw up a treatment plan, compare prognosis and curative effect, but also facilitates communication and exchange of colleagues, doctors and patients and medical skills. The intraoral dentition maxillofacial photograph can reflect the whole conditions of the whole dentition tooth body, mucosa and alveolar bone of a patient, and can reflect the occlusion condition of the whole dentition of the patient after occlusion detection by using occlusion paper, so that the intraoral dentition maxillofacial photograph is an indispensable important group of photographs. The existing form design of the mouth angle drag hook is not convenient for shooting the picture of the upper and lower jaw full dentition maxillofacial radiograph: the I-shaped lip retractor has small traction area, although the jaw face reflector cannot be prevented from being placed by traction, the too small contact area between the I-shaped lip retractor and the upper lip and the lower lip cannot be pulled to the center of the lip, so that the tooth labial surface of the upper front tooth area and the lower front tooth area and the shape and the outline of gingiva and alveolar bone in corresponding areas are difficult to expose when a picture is taken; the contact area of the T-shaped mouth corner draw hook with the upper lip, the lower lip and the mouth corner is large, the drawing area is large, the shapes of dentition, gum and alveolar bone can be well exposed, but the jaw face reflecting plate cannot be deeply placed due to the large extension range of the mouth lip groove, so that the far jaw face in a tooth grinding area is not completely photographed, and the patients can feel nausea and other uncomfortable reactions if the mouth corner of the patients is excessively drawn. Therefore, the mouth angle drag hook with the existing shape design is used for shooting the odontograph and maxillofacial picture, which brings great inconvenience to doctors and patients and also influences the final shooting effect and quality.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a full dentition jaw face of quarter arc shines nook closing hook has solved current nook closing hook form or because the volume is too big, hinders the reflector panel and places and lead to grinding the long-range shooting of tooth district incomplete, perhaps because tractive area of contact undersize leads to upper and lower jaw anterior labial surface, gum and alveolar bone profile to expose incomplete, finally makes upper and lower jaw dentition jaw face shine and shoot inefficiency, the poor problem of quality.

In order to solve the technical problem, the utility model discloses a realize through following technical scheme:

the utility model relates to a quarter arc full dentition jaw face shines angular drag hook, including lip recess and pull hook handle, the lip recess includes interior side wing and outside wing, and the wing edge of interior side wing is slightly wider than the wing edge of outside wing and the distance of lip recess tank bottom slightly with the distance of lip recess tank bottom. The lip groove is in a 1/4 circular arc groove shape, and one end of the outer side wing of the lip groove is fixedly connected with the drag hook handle.

Furthermore, a mallet-shaped part is arranged at the tail end of the draw hook handle, and a cross-grain convex rib is arranged on the surface of the mallet-shaped part.

Further, the distance from the edge of the inner wing side wall to the lip groove bottom is wider than the distance from the edge of the outer wing side wall to the lip groove bottom.

Furthermore, the connecting part of the outer side wing and the pull hook handle is an arc surface.

The utility model discloses following beneficial effect has:

1. the utility model discloses the lip recess only is located one side of hook handle, can fully contact when shooting dentition jaw face and shine and shoot the side lip tissue, pull open the lip traction, fine exposure dentition, gum and alveolar bone profile, simultaneously because of it does not have to block jaw lip recess, the reflector panel is shot to the jaw face can easily put into under the uncomfortable situation such as not arousing the patient to nausea in the mouth, and the reflector panel is convenient for put as far as possible after shooting the far-away jaw face form in molar area, the efficiency and the quality of shooting the dentition jaw face and shine in the oral cavity in clinical work have been improved.

2. The utility model discloses can be applied to the shooting to the jaw after changing with the mode of exchange quadrant (upper left and lower right, upper right and lower left). After the maxillary dentition photographing is completed, the left upper corner retractor is replaced to the lower right, the right upper corner retractor is replaced to the lower left, the lower lip can be fully pulled by the same operation, the lower lip is separated from the tooth surface, the lower dentition maxillofacial form, the gingiva and the alveolar bone contour are exposed, and the use is convenient.

3. The utility model discloses the width of lip angle drag hook through the inboard wing of broadening lip recess makes its bigger area contact with lip mucous membrane side, can fully tractive lip tissue, shows out the mucosa inflection department of vestibular ditch, better exposes preceding tooth district labial surface, gum and alveolar bone profile.

Of course, it is not necessary for any particular product to achieve all of the above-described advantages at the same time.
