Detailed Description
It is to be understood that the following detailed description is exemplary and is intended to provide further explanation of the invention as claimed. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.
As described in the background art, in the prior art, the small opening distance of the oral cavity of a patient is difficult to determine, the separation effect of the palate and the tongue is poor, the quality of scanned images is poor, and double images exist.
Example one
In an exemplary embodiment of the present invention, referring to fig. 1-2, a CBCT auxiliary scanning bite pad includes a bite portion, the bite portion includes an upper bite portion 2 and a lower bite portion 1, the upper bite portion 2 and the lower bite portion 1 have the same structure, and are relatively fixed and spliced to form the whole bite portion, the top surface of the upper bite portion 2 is used for biting upper teeth of a patient, and the bottom surface of the lower bite portion 1 is used for biting lower teeth of the patient.
Further, go up on the bottom surface of interlock portion 2 and correspond on the top surface of interlock portion 1 down and be equipped with a plurality of recesses, the recess is the hemisphere to form whole spherical space after last interlock portion docks with lower interlock portion, be used for holding stereoplasm ball 5 in the spherical space, thereby realized that stereoplasm ball 5 is embedded into in interlock portion, spherical space evenly distributed in interlock portion, thereby realized the evenly distributed of stereoplasm ball 5 in interlock portion.
In a preferred embodiment, the hard beads 5 are distributed in a quincunx shape in the occlusion part, and the distance between two adjacent hard beads 5 is 2-5mm, preferably 2mm, so that the occlusion part can better adapt to the occlusal surfaces of upper and lower teeth, ensure the large-area contact of the occlusal surfaces, adapt to a complex occlusal surface socket groove structure, avoid the interference on occlusion, and better fix the relationship between the upper jaw and the lower jaw.
In order to prevent tissues on the labial-buccal side and tissues on the lingual body from entering the gap and ensure that the thickness of soft tissues such as gingiva and the like in the tooth lacking area can be clearly measured after CT reconstruction so as to select a proper healing base station in the later period, the outer ends of the upper occlusal part and the lower occlusal part are provided with buccal parts 3, and the inner ends of the upper occlusal part and the lower occlusal part are provided with lingual parts 4. The buccal portion 3 is arranged perpendicular to the bite portion. The lingual side portion 4 is perpendicular to the occlusal portion, when the upper and lower teeth of a patient are occluded with the occlusal portion, the buccal side portion 3 is fixed on the outer side of the rear teeth, and the lingual side portion 4 is fixed on the inner side of the rear teeth, so that the buccal side portion 3 and the lingual side portion 4 are fixed on two sides of the rear teeth, the position of the occlusal portion is limited and fixed, and the occlusal portion is prevented from sliding radially.
In another embodiment, the buccal side part and the lingual side part are arranged in an arc shape relative to the occlusion part, which tends to the occlusion part, thereby facilitating the buccal side part and the lingual side part to be better tightly attached to the two sides of the posterior teeth and ensuring the adequate fixation of the occlusion part when occluded.
Simultaneously in order to prevent that the occlusion part from sliding along the posterior teeth, the top of the upper occlusion part 2 and the bottom of the lower occlusion part 1 are provided with a plurality of round point-shaped bulges so as to form anti-skid particles, the round point-shaped bulges and the upper occlusion part 2 and the lower occlusion part 1 are of an integrated structure, the occlusion part and the round point-shaped bulges are made of high polymer materials and have certain yielding property and flexibility, so that the wide occlusion contact can be conveniently established through the bending deformation of the occlusion part when a patient bites the occlusion part, the large-area contact of the occlusion surface is ensured, and the round point-shaped bulges have the function of increasing the friction force between the occlusion parts and the occlusion surfaces of the teeth.
Further, many stereoplasm beads 5 of interlock portion inside are plum blossom shape and distribute, the stereoplasm bead does not have the yieldability, it is used for as the interlock stop, rely on the not yieldability of stereoplasm bead 5 to be used for the definite of vertical distance when realizing the patient interlock, the distance of control occlusal surface is a fixed value, thereby realize that the interlock pad is better satisfies the interlock relation, when follow-up shooting CBCT, the vertical distance in interlock district can very easy calculation, wherein the distance between upper and lower jaw relies on the diameter of stereoplasm bead 5 to obtain, it facilitates to make treatment scheme clinically.
The occlusion part made of high molecular polymer material is soft, and is not developed in the oral cavity CT shooting, and no occlusion pad image exists in the oral cavity CT image, but the upper and lower teeth are uniformly separated under the action of the hard ball 5, and the tooth shape in the shot image is clear and has no overlapping phenomenon.
Specifically, the diameter of the hard ball 5 is equal to the thickness of the occlusion part, the hard ball 5 cannot fall off from the occlusion part, the occlusion part is arranged in a rectangular shape, the thickness of the occlusion part is 2mm, the occlusion part is consistent with the jaw stopping clearance, the size of the occlusion part is preferably 15mmx30mm, the hard ball can be cut into different sizes according to the situation, and therefore the hard ball is convenient to be suitable for patients with different oral cavity conditions and is simple to operate.
The lengths of the buccal part 3 and the lingual part 4 are equal to the length of the occlusion part, so that the manufacturing is convenient, the buccal part 3, the lingual part 4 and the occlusion part are of an integrated structure, or in another embodiment, the lengths of the buccal part 3 and the lingual part 4 are smaller than the length of the occlusion part, so that the cost is saved, and as long as the fixation and the limitation of the occlusion part can be realized and the occlusion part is prevented from sliding.
When shooing oral cavity CT to the patient, at first according to the oral cavity condition of patient, select one or more interlock pad, the patient opens one's mouth, prevent the patient back tooth district with the interlock pad, the position of adjustment interlock pad, it supports respectively in back tooth both sides to set up cheek lateral part and tongue lateral part, let patient's back tooth carry out the interlock to the two sides of interlock portion, under the effect of the nothing of the property of allowability and the stereoplasm ball of interlock portion, the realization is to the fixed of upper and lower jaw relation, let the patient guarantee static this moment, shoot patient's oral cavity CT image.
According to the design of the occlusion pad, a patient only needs to bite the occlusion pad with force slightly, so that the upper jaw and the lower jaw can be fixed, the distance between the upper jaw and the lower jaw cannot change under the action of the hard ball in the process of CT image shooting, the obtained image has no double image and has a fixed vertical distance equivalent to the diameter of the ball, and the later-stage image processing and measurement are facilitated.
The occlusal pad of the embodiment can ensure the imaging quality, and the distance of the occlusal surface is controlled to be a fixed value through the rigid ball without allowability on the basis of ensuring the large-area contact of the occlusal surface, so that the vertical lacuna of the edentulous area is convenient to measure.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
