Description
Technical Field
The invention relates to the technical field of oral medical appliances, in particular to a three-in-one aesthetic ruler for oral cavity repair, namely tooth body-dentition-face analysis.
Background
The oral cavity aesthetic restoration is a clinical medical technology for remodelling or maintaining the coordination and beauty of the oral cavity and the whole facial part of a patient by designing and processing the shape, the size and the position of the front teeth on the premise of ensuring the functional restoration of the front teeth which directly influence the beauty of the facial part of the patient. In the process of aesthetic restoration of the mouth, aesthetic measurement and analysis of the teeth, mouth and face of a patient are required.
At present, aesthetic measurement and analysis of teeth, oral cavity and facial parts of patients have the problems of complex operation, difficult quantification, large subjective randomness and the like. For example, "dental analysis" of the shape and size of the anterior teeth is a ruler, which measures the height of the anterior teeth of a patient before restoration, then measures the width of the anterior teeth, records separately, and then derives whether the width or height of the anterior teeth requires aesthetic restoration and the restoration amount thereof. The number and size of anterior teeth are analyzed by taking a ruler, measuring the total width of the teeth to be restored of the patient, and then measuring the width of artificial teeth of different types (the missing teeth are filled with artificial teeth), so as to select the model and the number of the artificial teeth. "facial analysis" involving anterior tooth position and size requires "facial scale measurement", "facial nose lip angle measurement", "facial Ricketts line measurement", and "1/3 distance measurement under the face". The face proportion measurement is to hold a ruler, measure the distance from the pupil connecting line to the nose wing connecting line of a patient, and judge whether the front tooth position needs to be moved upwards or downwards according to the difference between the two distances; taking a picture of the side face of the patient, and measuring the angle of the side face nose lip angle by using a protractor in the picture to further obtain whether the front teeth need to move forward or retract; the side-view Ricketts line measurement is that a line is drawn between the nose tip and the front chin point of a patient, and a ruler is used for measuring the distance from the lip bead of the patient to the line; and then whether the front teeth need to lean forward or lean backward or not. The "1/3 distance measurement under the face" is to measure the distance from the nose to the chin by using a ruler to obtain the up-and-down movement distance of the front teeth before and after restoration.
In summary, the measurement and analysis of the oral cavity aesthetics in the existing oral cavity aesthetic restoration are required to be performed in three aspects of "tooth body-tooth row-face". Different straightedges or protractors are needed to be used for each measurement, corresponding scribing, alignment and comparison measurement operations are needed to be carried out; then subjective judgment and design are carried out. The method is complex in operation, high in subjective randomness and poor in reliability, and the effect of aesthetic restoration of the oral cavity is difficult to ensure.
Disclosure of Invention
The invention aims to provide a three-in-one aesthetic ruler for dental restoration, namely tooth body-dentition-face analysis. The aesthetic ruler can be used for both dental analysis and dentition analysis and also for measurement of facial analysis; the oral cavity aesthetic measurement in the oral cavity aesthetic restoration is simpler and more convenient; the measurement and analysis results are more objective and accurate; thereby improving the aesthetic restoration effect of the oral cavity.

The main scale is marked with scales, wherein the 0 scale starts from the axis of the auxiliary scale and extends leftwards and rightwards by 80mm, a pointed tooth transverse line is arranged at 23mm-25mm, a square tooth transverse line is arranged at 25mm-26.5mm, and an oval tooth transverse line is arranged at 23.5mm-25.5 mm;
the center of the cross ruler is a 0 scale, the transverse scale of the cross ruler extends from the 0 scale to the left and right for 6mm, and tooth height standard lines are marked at the positions of 5mm-5.5 mm; the vertical scale of the cross ruler extends 5mm up and down from the 0 scale; and marking a tooth width standard line at the position of 4mm-4.5 mm;
the radian of the radian ruler is 120 degrees, and the scale of 0 begins at the joint of the radian ruler and the main ruler;
the total length of the auxiliary ruler is 30mm, the distance between the position of the 0 scale of the auxiliary ruler and the upper end of the auxiliary ruler is equal to the thickness of the main ruler, the upper part of the auxiliary ruler is marked with a positive scale extending to the upper end part, and the lower part of the auxiliary ruler is marked with a negative scale extending to the lower end part.
The application method of the invention is as follows:
tooth analysis:
the main scale is rotated clockwise by 90 degrees, so that the cross scale at the left end of the main scale is upwards, the width of the central incisors (the two foremost upper teeth) is measured by the transverse ratio of the vertical scale of the cross scale, and the two side edges of the central incisors can respectively fall on the corresponding tooth width standard lines of the vertical scale, so that the central incisors of a patient have proper width without aesthetic restoration; otherwise, the actual width of the patient's central incisors is measured with a vertical ruler, and aesthetic restoration data (difference between the actual width and the upper limit of the standard width of the tooth width) of the patient's central incisors is obtained. Then the horizontal rule of the cross rule is used for comparing the heights of the central incisors, and the top edge and the bottom edge of the central incisors can respectively fall on the corresponding tooth height standard lines of the horizontal rule, so that the central incisors of patients are proper in height and aesthetic restoration is not needed; otherwise, the actual height of the middle incisors of the patient is measured by a transverse ruler, and then aesthetic restoration data (the difference between the actual height and the upper limit of the standard height of the tooth width) of the middle incisors of the patient is obtained. Thereby completing the dental analysis.
Dentition analysis
Aligning the 0 scale of the main scale to the midline of the patient (the centerline of the face); judging whether the patient surface shape is pointed, square or oval, if the transverse gap of the missing teeth of the quasi-patient falls on the marking corresponding to the tooth shape on the main scale, selecting the middle artificial tooth corresponding to the tooth shape; if the transverse gap of the missing teeth of the quasi-patient exceeds the outer end part of the marking corresponding to the tooth shape on the main scale, the actual transverse width of the missing teeth of the patient is read out to determine to select large artificial teeth corresponding to the tooth shape or increase the number of the artificial teeth; if the transverse gap of the missing teeth of the quasi-patient cannot reach the inner end part of the marking corresponding to the tooth form on the main scale, the actual transverse width of the missing teeth of the patient is read out to determine to select small artificial teeth corresponding to the tooth form or reduce the number of the artificial teeth; thereby completing the dentition analysis.
Face analysis:
A. face ratio measurement:
the main scale is rotated clockwise by 90 degrees, the pair of auxiliary scales Ji Biyi is further rotated, the left sliding block is slid to enable the length fingers of the left sliding block to be aligned with the connecting lines of the two pupils, the right sliding block is slid to enable the length fingers of the right sliding block to be aligned with the lower edges of the chin, the scale of the left sliding block length pointer on the main scale is read, namely, 1/3 of the length of the face of a patient is measured, the scale of the right sliding block length pointer on the main scale is read, and the 1/3 of the length of the face of the patient is measured. If the 1/3 length of the face is larger than the 1/3 length of the face, the occlusion is correspondingly raised (the tooth body is heightened), otherwise, the occlusion is correspondingly lowered, so that the face proportion of the patient after the oral cavity is repaired is more coordinated.
B. Side appearance nose lip angle measurement:
the arc pointer is aligned with the small nose column, the right part of the main scale is aligned with the labial sulcus, the arc of the arc pointer on the arc scale is read, and then the lateral nasolabial angle of the patient is measured, if the nasolabial angle is between 90 and 110 degrees, the upper anterior teeth are required to be adducted to reduce the fullness of the upper lips, and if the upper anterior teeth are greater than 110 degrees, the upper lip fullness is required to be increased by external movement of the upper anterior teeth.
C. Side appearance Ricketts line measurement:
the notch of the main ruler faces the lips, and the main ruler is contacted with the nose tip and the chin of a patient at the same time, and at the moment, the upper edge line of the main ruler is a Ricketts line; then sliding the auxiliary ruler to enable the end part of the auxiliary ruler to contact the lip bead; and reading the scale at the alignment position of the lower edges of the auxiliary ruler and the main ruler, namely measuring the distance between the Ricketts line and the lip bead. If the distance is between +5mm and-5 mm, the mouth repair is not needed, if the distance is less than-5 mm, the cut end of the upper front teeth needs to be screwed outwards to increase the fullness of the upper lips, and if the distance is more than +5mm, the cut end of the upper front teeth needs to be screwed inwards to reduce the fullness of the upper lips.
Compared with the prior art, the invention has the beneficial effects that:
1. the invention can simply and conveniently complete the corresponding measurement and analysis of the tooth analysis by utilizing the cross ruler at the right end of the aesthetic ruler and the scales on the cross ruler. The standard thread for tooth height and width makes the measurement and analysis faster, more accurate and objective.
2. The corresponding measurement and analysis of the tooth analysis can be simply and conveniently finished by utilizing the scales in the middle of the main scale of the aesthetic scale. The three tooth type marked lines of the pointed tooth, the square tooth and the oval tooth enable measurement and analysis to be quicker, more accurate and objective. The notch in the middle of the main ruler can avoid the nose, so that the measurement error caused by the inclination of the main ruler and the remote visual estimation is reduced, and the measurement is more accurate and reliable.
3. The side appearance nose lip angle of the patient can be directly measured by using the radian pointer, the radian ruler and the main ruler. The main scale, the auxiliary scale, the left sliding block and the right sliding block are matched, so that the length of 1/3 of the face of the patient and the length of 1/3 of the face below the face can be measured at one time, and the face proportion is obtained. The distance between the Ricketts line and the lip bead can be directly measured by using the auxiliary ruler and the main ruler. The measurement operation of the facial analysis is simpler and quicker.
In summary, the aesthetic scale of the present invention can be used for both dentition and facial analysis measurements; the oral cavity aesthetic measurement in the oral cavity aesthetic restoration is simpler and more convenient; the analysis result is more objective and accurate, and the effect of aesthetic restoration of the oral cavity is further improved.
Further, the right part of the main ruler is also sleeved with a transparent large slide block; the rear side of the large sliding block is inserted with a vertical clamping support in a sliding way; the lower part of the clamping support is rectangular, the shape on the right side of the upper part is matched with the chin of a person, and the clamping support is marked with a vertical marking line.
After the transparent large slide block is sleeved, the osseology measurement of 1/3 distance below the surface can be carried out:
the right end of the main scale is propped against the nose of a patient, the large slide block is moved, the clamping support on the large slide block supports the chin, the scale of the alignment position of the clamping support marking and the main scale is read, and the difference between the scale and 80mm is the measured ossiness measurement value of 1/3 distance below the surface. During measurement, two supporting points of the ruler and the face of the patient are in bone supporting contact with bone parts, but not in contact with soft tissues with light surface, so that the measurement of the distance 1/3 below the face is more accurate and good in repeatability, and the method is used for comparing and repairing the accurate measurement of the distance 1/3 below the front and rear faces.
The main scale and the large sliding block can be used for measuring the ossiness of the 1/3 distance below the surface. During measurement, two supporting points of the ruler and the face of the patient are in bone-supporting contact with bone parts, so that measurement errors caused by the flexibility and tension of soft tissues are reduced.
