Technical Field
The application relates to the field of measurement technology, in particular to an auxiliary guide plate for measuring alveolar bone.
Background
The alveolar bone can be absorbed and retracted in various directions to different degrees within 6 months after tooth extraction or tooth deletion, the bone quantity deficiency can affect the later planting effect, and bone filling materials and isolating membranes are implanted to promote bone regeneration and slow down alveolar bone atrophy through bone guiding regeneration.
The main methods for evaluating the change of the height and width of the alveolar bone after bone conduction regeneration are as follows: direct measurement of periodontal probe and caliper, parallel projection of root tip examination, CBCT examination (cone beam CBCT), etc. The periodontal probe and the caliper direct measurement method are used, and the periodontal probe and the caliper direct measurement method are measured in the operation process, so that the periodontal probe and the caliper direct measurement method are needed by a doctor with abundant experience, the operation time is long, and the pain of a patient is strong; the parallel projection method is obtained by measuring and calculating the digital root tip slice of the tooth-missing area of the patient through the enamel cementum boundary of the adjacent teeth or the stable reference points such as the edge of the restoration, and the method has limited shooting range and can only display near-far middle two-dimensional images.
CBCT measurement measures alveolar bone morphology by CBCT three-dimensional imaging. However, the imaging angles of the patients are different in each imaging, the alveolar bone is reconstructed after the tooth defect, the morphology is changed, the reference points/surfaces are different in each measurement, and the result is error due to the lack of a fixed reference limit.
Disclosure of Invention
In order to improve the defect that the error of a measurement result is large when the appearance of the alveolar bone is measured through CBCT three-dimensional images, the application provides an auxiliary guide plate for measuring the alveolar bone.
The application provides an alveolar bone is measured and is used auxiliary guide plate adopts following technical scheme:
an auxiliary guide plate for alveolar bone measurement, comprising:

Optionally, the positioning assembly further comprises a third positioning bead fixedly arranged on the guide plate main body corresponding to the midpoint of the gingival margin of the missing tooth of the subject.
By adopting the technical scheme, when the CBCT scanning result is measured, the coronal plane and the sagittal plane can be determined by the position of the third positioning bead and the position of the reference plane, so that the height and the width of the alveolar bone can be conveniently measured.
Optionally, when the third positioning bead is fixedly disposed on the guide plate main body corresponding to the midpoint of the gingival margin of the embedded wisdom tooth of the subject, a fourth positioning bead is fixedly disposed on the guide plate main body corresponding to the midpoint of the gingival margin of the tooth adjacent to the embedded wisdom tooth of the subject.
By adopting the technical scheme, when the alveolar bone of the embedded wisdom tooth of the subject is measured, the third positioning bead on the guide plate main body corresponding to the middle point of the gingival margin of the embedded wisdom tooth of the subject can be displayed unclear in the CBCT scanning result due to the position relation, at the moment, the position of the fourth positioning bead on the guide plate main body corresponding to the middle point of the gingival margin of the tooth adjacent to the embedded wisdom tooth of the subject in the CBCT scanning result can be used as a reference point, the defect of lower accuracy of the measurement result when the alveolar bone of the embedded wisdom tooth of the subject is measured is avoided, the measurement accuracy of the guide plate main body is further improved, and the application range of the guide plate main body is increased.
Alternatively, the guide plate body is made of a resin material.
Through adopting above-mentioned technical scheme, because when CBCT scans, the different material development light and shade of density is huge, tooth, alveolar bone and bone grafting material density is higher, and the density of resin material is less, so through making the baffle main part by resin material, can avoid the baffle main part to exert an influence to the alveolar bone development when CBCT scans to can reduce the influence of baffle main part to the scanning result, thereby can be convenient for measure the alveolar bone in the CBCT scanning result, further improved measuring accuracy.
Optionally, the first positioning bead, the third positioning bead and the fourth positioning bead are all made of a ceramic material.
Through adopting above-mentioned technical scheme, because when CBCT scans, the material development effect to the density is great is stronger, and the density of pottery is great, so through making first location pearl, second location pearl, third location pearl and fourth location pearl by ceramic material, can improve first location pearl, second location pearl, third location pearl and fourth location pearl when CBCT scans, definition when developing to can be convenient for measure the alveolar bone in CBCT scanning result, measurement accuracy has further been improved.
Optionally, the first positioning bead, the third positioning bead and the fourth positioning bead are spherical.
By adopting the technical scheme, the manufacturing process of the micro spherical material is relatively mature, and the cost is low, so that the first positioning bead, the second positioning bead, the third positioning bead and the fourth positioning bead are arranged to be spherical, and the cost can be reduced to a certain extent.
Optionally, the first positioning bead, the third positioning bead and the fourth positioning bead have diameters ranging from 0.5 mm to 1.2 mm.
By adopting the technical scheme, since the width of one tooth is approximately between 5 mm and 10 mm, when the diameters of the first positioning bead, the second positioning bead, the third positioning bead and the fourth positioning bead are smaller than 0.5 mm, the first positioning bead, the second positioning bead, the third positioning bead and the fourth positioning bead are inconvenient to install on the guide plate main body; when the diameters of the first positioning bead, the second positioning bead, the third positioning bead and the fourth positioning bead are larger than 1.2 mm, the development area is larger, the height and the width of the alveolar bone are not convenient to measure in a CBCT scanning result, and the measurement error is easy to increase; so through setting the diameter size of first location pearl, second location pearl, third location pearl and fourth location pearl between 0.5 millimeter-1.2 millimeter, can improve its convenience of installation, further improve measuring accuracy nature.
In summary, the present application includes at least one of the following beneficial technical effects:
1. through the arrangement of the guide plate main body and the positioning component, when the CBCT scanning result is measured, the positioning component can be used as a reference object to measure the height and width of the alveolar bone of the subject, so that the defect of larger error of the measurement result of the traditional CBCT measurement method is overcome, and the accuracy of the measurement result is improved;
