the utility model provides a jaw stump locator under formula is supported to tooth, its characterized in that, is including the occlusal plate that is arc structure, the upper and lower surface of occlusal plate all is equipped with the constant head tank that the shape is unanimous with jaw somatic part dentition appearance, the arc tip an organic whole of occlusal plate is connected with the locating plate, seted up the fixed orifices on the locating plate and passed through the fixed orifices is worn to establish retention nail and temporomandibular joint fixed connection.
Optionally, the positioning plate is located at the arc end of either side of the bite plate.
Optionally, three fixing holes are formed in the positioning plate, and the three fixing holes are arranged in a triangular distribution mode.
Optionally, each of the fixing holes is a nail hole with a diameter of 2 mm.
Optionally, the bite plate and the positioning plate are integrally formed structures printed in 3D.
The utility model discloses technical scheme has following advantage:
1. the utility model discloses a jaw stump locator is supported to tooth, when the mandible cuts the bone and accomplishes, the jaw stump can become free bone piece, hardly keeps on primary importance to utilize the maintenance nail to pass the fixed orifices and fix the locating plate in temporomandibular joint, then make it coincide completely with the dentition appearance after reseing through the constant head tank on the occlusal plate, can reset the jaw stump to primary importance and guarantee temporomandibular joint's normal.
2. The utility model discloses a jaw stump locator under formula is supported to tooth because the precision that the formula location was supported to the tooth used the baffle location in jaw face surgery operation is the highest, so only set up the locating plate in arbitrary one side of occlusal plate, can ensure its overall stability to can shorten the time of preparation baffle, reduce the cost of preparation baffle, improve operation efficiency with this.
3. The utility model discloses a tooth supports formula mandible incomplete end locator has seted up three fixed orifices on the locating plate, and three fixed orifices is triangle-shaped's distribution mode setting to three nail hole decides a face on the one hand, can let the mandible incomplete end fix a position original position very accurately, improves fixed strength, and on the other hand it moves towards the orbit of having avoided the scalpel, with this accurate completion rebuild the type of moulding, its reliable degree obtains very big promotion.
4. The utility model discloses a jaw stump locator under formula is supported to tooth, and occlusal plate and locating plate utilize 3D printing technique for the integrated into one piece structure that 3D printed, make the operation more accurate reliable to through clinical experience, it is most accurate to tooth locate mode.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the embodiments or the technical solutions in the prior art will be briefly described below, and it is obvious that the drawings in the following description are some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.
Fig. 1 is a schematic structural view of a dental-support-type mandibular stump positioner according to an embodiment of the present invention.
Description of reference numerals:
1. a bite plate; 11. positioning a groove; 2. positioning a plate; 21. and (7) fixing holes.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The utility model provides a jaw stump locator under formula is supported to tooth, as shown in fig. 1, including the occlusal plate 1 that is arc structure, the upper and lower surface of occlusal plate 1 all is provided with the constant head tank 11 that the shape is unanimous with jaw somatic part dentition appearance to the arc tip an organic whole of occlusal plate 1 is connected with locating plate 2, has seted up fixed orifices 21 on the locating plate 2 and has worn to establish retention nail and temporomandibular joint fixed connection through fixed orifices 21. Therefore, when the mandible is cut, the stump of the mandible becomes a free bone block and is difficult to keep at the original position, so that the stump of the mandible is completely matched with the shape of the reset dentition through the positioning groove 11 on the occlusal plate 1, and then the positioning plate 2 is fixed at the temporomandibular joint by the fixing nail penetrating through the fixing hole 21, so that the stump of the mandible can be reset to the original position to ensure the normality of the temporomandibular joint. This structure is convenient for follow intraoral deep-going, compares the big positioning instrument of other structures, and is smaller and more exquisite, and the wound face is little to fixed orifices 21 is unanimous with the nail hole of the guide plate of taking one's place that the mandible rebuilds and use in this embodiment, in order to reduce the operation time, and accurately accomplishes and rebuilds the type.
As shown in fig. 1, the positioning plate 2 is located at the arc end of either side of the bite plate 1. Since the accuracy of the tooth-supported positioning is the highest in the jaw surgery using the guide plate, the overall stability of the bite plate 1 can be ensured by only providing the positioning plate 2 on either side thereof, and the time for manufacturing the guide plate can be shortened, the cost for manufacturing the guide plate can be reduced, thereby improving the operation efficiency.
As shown in fig. 1, three fixing holes 21 have been seted up on locating plate 2, and three fixing hole 21 is the setting of triangular distribution mode to a face is decided in three nail hole on the one hand, can let the jaw stump fix a position original position very accurately, improves fixed strength, and its orbit of moving towards and having avoided the scalpel on the other hand. In the embodiment of the utility model, every fixed orifices 21 is the nail hole that the diameter is 2mm, in the operation, through the titanium nail with the cooperation of fixed orifices 21, can firmly fix the tooth-supported formula mandible stump locator to temporomandibular joint to this accuracy is accomplished and is rebuild the type, and its reliable degree obtains very big promotion.
As shown in fig. 1, the bite plate 1 and the positioning plate 2 are integrally formed by 3D printing, and the operation is more accurate and reliable by using 3D printing technology. In addition, in this embodiment of the utility model, choose photosensitive resin material for use and make this tooth support formula mandible stump locator, it has solidification fast, shaping precision is high, surface effect is good, have class ABS performance, mechanical strength is high, low smell, resistant storage, characteristics that the commonality is strong.
This tooth supports formula mandible stump locator's theory of operation: when the mandible is cut, the stump of the mandible can become a free bone block and is difficult to keep at the original position, so that the stump of the mandible can be completely matched with the appearance of the tooth array after restoration through the positioning groove 11 on the occlusal plate 1, then the positioning plate 2 is fixed on the temporomandibular joint by utilizing the fixing nail to penetrate through the fixing hole 21, one surface is determined by the three nail holes, and the tooth-supported mandible stump positioner can be firmly fixed on the temporomandibular joint through the matching of the titanium nail and the fixing hole 21.
It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications can be made without departing from the scope of the invention.
