Description

AREA OF TECHNOLOGY

The invention relates to the field of medicine, in particular to orthodontics, namely to a method of computer orthodontic diagnostics based on unique human landmarks for planning orthodontic treatment in all three planes of space.

PRIOR ART

Various traditional methods of orthodontic diagnostics and assessment of maxillofacial harmony are known from the state of the art.

For the diagnosis of dentoalveolar anomalies, it is recommended to perform teleradiography of the head in the lateral projection or perform cone-beam computed tomography of the facial skull and use the data for TRG reformats to perform cephalometric analysis [1-6].

However, traditional cephalometric analyses are based on average normal data rather than on what is unique to each individual. According to Hamilton, J. (2007), there are already more than 250 such cephalometric analyses that use average normal data and intracranial landmarks [11].

However, the use of such landmarks can be unreliable due to both errors in their identification and differences in their location in each individual [8], and their incorrect interpretation often leads to the selection of an incorrect treatment strategy, resulting in unstable occlusion [7]. In addition, according to Cox, N.H. (1971), it was proven that good facial harmony exists over a wide range of traditional cephalometric parameters. Diagnosis based on such landmarks can lead to different diagnoses, treatment plans and, consequently, to different results [10].

A well-known method is proposed by L.S. Persin ("Assessment of the Harmonious Development of the Dentoalveolar System // New in Dentistry. - 1995 - No. 3. pp. 21-23), according to which the harmoniousness of occlusion is determined by the values of the angular parameters of teleradiographs of the head, characterizing the position of the molars and incisors and their occlusion. This method allows for an assessment of the harmonious occlusion of the dental arches, but does not provide the ability to determine the proportionality of the facial aesthetics and the occlusion of the dental arches.

There is a known method for assessing the harmony of the dental system according to A. Hasund (1989), according to which, based on the values of the angular parameters of the head teleradiography, the tolerance limits are determined, i.e. the limits of the norms taking into account the standard deviation. The following angular parameters are assessed: SNA, SNB, NSBa, NL-NSL, ML-NSL ML-NL, angles measured according to the head teleradiography in the lateral projection and compared with their maximum permissible values. Depending on the location of the parameters outside or within the permissible values or tolerance limits, the harmony of the patient's dental system development is determined (HasundA., Remme T.W. Nor. TannlaegeforenTid. 1967 Jun; 77 (6): 319-38.) http://ortodontam.pro/main/poor/33/690/.

A known method for assessing the patient's dental health (RU2703656C1, published October 21, 2019) involves performing a lateral head teleradiography while studying the morphometric parameters of the dental system. This method measures the angular parameters characterizing the occlusion of the dental arches: PoNA, PoNM, and the angular parameters reflecting the harmonious development of the dental system: PoNA, PoNB, ML-NL, MNI. Additionally, the angular parameter LP and the linear parameters reflecting facial aesthetics (PLV-sto, PLV-1/1) are measured and compared with their maximum permissible values. If the obtained data correspond to the norm and fall within the permissible limits, this indicates the harmonious status of the patient's dental health, while deviations from the norm indicate a lack of harmonious development of the dental system and, consequently, a violation of facial aesthetics. The method allows to evaluate the harmonious development of the dental system and occlusion of the dental arches and the aesthetics of the face.

However, these methods produce results that are then compared with average norms and maximum permissible values. However, each person is unique. Therefore, diagnosis and orthodontic treatment planning should be based on unique benchmarks, treatment goals should be universal, and targets should be tangible.

Such goals and their associated landmarks and markers are defined in the “Six Elements of Orofacial Harmony” [9].

The goals are comprehensive, maximal, harmonizing, and long-term for the health of the orofacial complex, as well as universal. Universality means that they work equally well for all patients, regardless of race, age, or gender.

A landmark is an anatomical point or line that has an exceptionally correct aesthetic shape and positional relationship with the teeth or jaws when they are optimally positioned. It is used as a standard for measuring the quality of the teeth or jaws' position. The "Six Elements" landmarks are anatomically identical for all patients, but have a unique shape and position for each individual.

A marker is an anatomical point or line representing a tooth or jaw. It is used to measure the quality of positioning relative to a unique landmark.

SUMMARY OF THE INVENTION

Accordingly, there is a need to address at least some of the above mentioned shortcomings.

The technical problem that this invention aims to solve is to improve the quality of treatment by increasing the accuracy of orthodontic diagnostics.

Achieving the set goals is possible with the help of computer orthodontic diagnostics, which includes determining the parameters of the patient’s skull, computer analysis of the parameters, and determining an orthodontic treatment plan.

The claimed method is characterized by the fact that at the first stage the forehead shape is determined, the clinical forehead is measured and the unique boundary of the optimal anterior-posterior position of the jaws is estimated using a 3D photo of the patient, data is transferred from the 3D photo of the face to a teleroentgenogram (TRG) of the head in the lateral projection, the clinical forehead and GALL line data are transferred, TRG of the head in the lateral projection, and the return to the true vertical position is based on the GALL line, then the heights of the face are estimated on the TRG based on the position of the lips at rest, adding a chin protrusion point, adding an occlusal plane, selecting an occlusal plane - a single one if there is no divergence or double, separate occlusal planes, in cases with divergence, matching the upper occlusal plane with the upper occlusal plane of the patient in a digital template of the optimal position of the upper incisors, after the appearance of a digital template of the optimal position of the incisors, the lower occlusal plane of the template must be matched with the lower occlusal plane of the patient, if clinically determined Discrepancy of the central relation/central occlusion, it is necessary to indicate this in the corresponding field and the program will automatically take this discrepancy into account and correct the anterior-posterior position of the lower jaw, determination of the discrepancy along the baseline for the upper and lower jaws, in which the free space for a specific tooth is measured, then the width of the tooth itself is measured, this process is repeated for each tooth that has a discrepancy, setting the points of deflection of the occlusal plane of the dentition of the upper jaw, the location of the points for measuring the inclination of the molars of the upper and lower jaws on the right, the location of the points for measuring the inclination of the molars of the upper and lower jaws on the left, selection of a treatment plan.

In the preferred embodiment for the compromise treatment plan, it is necessary to continue the diagnostic process, the contours of the incisors in the compromise treatment plan mode will become colored red, which will indicate the transition to the compromise treatment plan mode.

In the preferred embodiment, it is possible to enter data after manual analysis of plaster models of dental arches, as well as computer analysis of 3D models of dental arches.

EMBODIMENT OF THE INVENTION

According to the embodiment shown in Fig. 1, the first stage of computerized orthodontic diagnostics using unique human landmarks is forehead shape determination, clinical forehead measurement, and assessment of the unique boundary of optimal anterior-posterior jaw position (FA/GALL assessment). 3D facial photo files are loaded into the program.

It is necessary to select the appropriate “forehead type” and set the flags on the surface of the soft tissues of the forehead according to the 3D photo of the face (Fig. 1).

Clinical forehead measurement and FA/GALL assessment are performed using a 3D photograph of the patient's face. This method is non-invasive, does not require diagnostic measuring equipment, and is readily available.

The program will automatically measure the clinical forehead and display the distance in mm (Fig. 2).

Next, a point is established at the midpoint of the clinical crowns of the central incisors (at the level of the FA points) (Fig. 3). After this, the 3D photo of the face should be rotated in profile and the true frontal plane of the head assessed by setting the lowest point of the GALL line – set the Inf point. The program will automatically construct the GALL line and calculate the distance in mm from the FA point to the GALL line (Fig. 4).

The obtained data will always be displayed and transferred to the TRG of the head in the lateral projection (Fig. 5).

Estimating facial height: A method based on resting lip position

After transferring the clinical forehead and GALL line data, the TRG of the head in the lateral projection will be automatically scaled and standardized - rotated to a true vertical position based on the GALL line.

To assess the heights, horizontal lines should be positioned at the same level as the subnasal (Sn), soft tissue Menton (Me), Condylion (Co), Gonion (Go), and the lower border of the upper lip (UL). It is important that the patient's lips are at rest (Fig. 6).

Adding a chin point (Pg)

The horizontal line is established at the level of the incisal edge of the mandibular central incisor. The "FA" flag should be positioned at the FA point of the mandibular central incisor, and the "Pg" flag should be positioned at the bony point of the Pogonion (Fig. 7).

Adding occlusal plane(s)

The next step is to select the occlusal plane—either a single plane if there is no divergence, or a dual, separate occlusal plane if there is divergence. If the occlusal plane is a single plane, it must be positioned at the level of maximum occlusion of all teeth (the functional occlusal plane), using flags "A" and "B" (Fig. 8).

If necessary, you can select "separate occlusal planes." This will create a second, separate occlusal plane, which must be positioned separately using the "A," "B," "A'," and "B'" checkboxes (Fig. 9).

Digital diagnostic template for optimal incisor positioning for the upper jaw

The next step will display a digital template for the optimal position of the maxillary incisors. The upper occlusal plane of the template must be aligned with the patient's upper occlusal plane. You can move the template forward or backward along the occlusal plane until the root of the upper incisor is centered in the bone—the optimal position. Simply click on the outline of the upper incisor on the template, and the incisor will automatically be highlighted in green (Fig. 10).

If desired, you can always delete the incisor outline or move it along the occlusal plane (Fig. 11 A, B). You can also change the template color to white for better visibility or hide it completely.

Digital diagnostic template for optimal positioning of incisors for the lower jaw

Once the digital template for optimal incisor positioning appears, the lower occlusal plane of the template must be aligned with the patient's lower occlusal plane. The digital template must be moved forward or backward along the occlusal plane until the root of the lower incisor is centered in the bone—the optimal position. Simply click on the outline of the upper incisor on the template, and the incisor will automatically be highlighted in green (Fig. 12).

If desired, you can always remove the incisor outline or move it along the occlusal plane (Fig. 13 A, B).

Central relation/central occlusion (CR/CO)

If a CR/CO discrepancy is clinically determined, it must be indicated in the appropriate field and the program will automatically take this discrepancy into account and correct the anterior-posterior position of the lower jaw (Fig. 14).

When printing the diagnostic results, the program will automatically add a mark to the image indicating that during the conversion of the image from CO to CR, a displacement of the lower jaw occurred in the vertical and/or sagittal plane.

Use of plaster models of dental arches

The program is equipped with the ability to enter data from both manual analysis of plaster models of dental arches and computer analysis of 3D models of dental arches.

Analysis of the 3D model of the upper dentition

To perform diagnostics of the upper dental arch, simply drag the 3D file of the upper dental arch model into the field (the program accepts the most popular formats of volumetric objects - *.STL and *.PLY formats), to start the upper dental arch, or click the "Select file" button and select the 3D file of the model on your local computer.

Assessment of the width of the dental arch before treatment

To assess the dental arch width before treatment, set points on the mesial palatal cusps of the maxillary first molars. After setting the dental arch width points, click "Next" (Fig. 15).

Divergence along the main line

At this stage, it is necessary to determine the discrepancy (crowding or gaps) along the baseline. First, the free space for a specific tooth is measured (Fig. 16), then the width of the tooth itself is measured (Fig. 17).

This process is repeated for each tooth that has discrepancy (gaps between teeth or crowding) (Fig. 18).

You can skip this step, and then the discrepancy value will be automatically determined as 0 mm.

Curve of Spee of the upper dentition

Establish the occlusal plane by placing three points as shown in Fig. 19.

Set the deflection points of the Spee curve on the right and left (Fig. 20).

Inclination of molars

To determine the inclination of the molars, place three points on the vestibular surface of the first maxillary molar on one side as shown in Fig. 21.

Repeat the same for the molar on the opposite side (Fig. 22).

This step can be skipped, in which case the molar inclination will be taken as optimal (- 9°) and the effect on the dentition will be 0.

Analysis of the 3D model of the upper dentition

To perform a diagnosis of the lower dental arch, simply drag the 3D file of the lower dental arch model into the field (the program accepts the most popular formats of volumetric objects - *.STL and *.PLY formats), or click the "Select file" button and select the 3D file of the model on your local computer.

Width of the dental arch before treatment

Place the dots in the central fossae of the first molars of the lower dentition (Fig. 24).

Divergence along the main line

Identify discrepancies (crowding or gaps) along the baseline.

First measure the free space for a particular tooth (Fig. 25), then measure the width of the tooth itself (Fig. 25).

Repeat this process for each tooth that has a discrepancy (gaps or crowding) (Fig. 27). You can skip this step, and the discrepancy value will be automatically determined as 0 mm.

Curve of Spee of the lower dentition

Establish the occlusal plane by placing three points as shown in Fig. 30. Establish the deflection points of the curve of Spee on the right and left (Fig. 28).

Locating the first mandibular molars in relation to the corresponding WALA ridge

Set the FA point on the first lower molar on one side. Set the WALA point on the ridge adjacent to the molar (Fig. 30).

Repeat the same for the molar on the opposite side (Fig. 31).

This step can be skipped. In this case, the position of the FA point of the first lower molar to the WALA crest will be considered optimal (2 mm), and the effect on the dental arch will be zero.

After manually entering data from plaster models or performing a 3D analysis of the dental arches, the user is taken to a page where all skeletal and dental data will be fully entered. The specialist will be able to review everything again and make any necessary changes (Fig. 32).

The “Finish” button is pressed and the program generates an optimal treatment plan (Fig. 33).

The user will always be able to print or generate a *.PDF file of the optimal treatment plan along with a standardized TRG of the head in the lateral projection, on which all the necessary lines will be applied, and the incisors will be in the optimal position (Fig. 34).

Compromise treatment plan

Active cutting edge movement mode with compromise

To develop a compromise treatment plan, the diagnostic process must be continued. The incisor contours in the compromise treatment plan mode will turn red, indicating the transition to compromise treatment plan mode (Fig. 35).

The red contours can be moved by body movement (torque) within safe physiological limits (+/- 2 mm) or by tilting (tipping), guided by the treatment goals.

It is always possible to change the center of rotation of the incisors by changing the corresponding mode - in the area of the root apex (Fig. 36), in the area of the middle of the root (Fig. 37), or in the area of the FA (tork) point (Fig. 38).

Defining intentions for compromise

In the default compromise treatment plan, all skeletal elements will automatically be marked with the letter "G," signifying no intention to alter the jaws in any way. The user can make any necessary changes if desired (Fig. 39).

After clicking the "Calculate" button, a fully completed treatment plan will be generated. The user receives a fully completed diagnostic sheet with the optimal and compromise treatment plans (Fig. 40).

The proposed method of computerized orthodontic diagnostics based on unique human landmarks is accurate, non-invasive, and does not require physical materials such as impression material, plaster, printing polymers, diagnostic templates, and rulers. This, in turn, allows for cost-effectiveness, reduces the time required for orthodontic diagnostics, and optimizes the clinician's work time. The proposed method of computerized orthodontic diagnostics allows for visualization of the treatment plan and its presentation to patients and any specialists in real time (online), opening up the possibilities of telemedicine in orthodontics.

INDUSTRIAL APPLICATION

The proposed method is used in medicine for the diagnosis and treatment of dental anomalies.
