Description

A method of obtaining jaw position after programming the masticatory muscles using a digital gum balancer

technical field

The invention relates to a digital method, in particular to a method for obtaining a jaw position after programming the masticatory muscles using a digital gum balancer.

Background technique

Temporomandibular Disorders (TMD) is not a single disease, but a general term for diseases involving pain and dysfunction of temporomandibular joints and masticatory muscles. It ranks fourth in the ranking of common diseases in stomatology, and the main symptoms are These are joint snapping, murmurs, pain in the joint area, and jaw movement disorders.

A large amount of clinical and research evidence has shown that TMD has comorbidity with pain in multiple parts of the body. Cervical Spinal Disorder (CSD) is one of the more common diseases. The etiology of CSD is complex and the clinical manifestations are diverse. The main symptom is neck and shoulder pain. Shoulder muscle tenderness. Because TMD patients are often accompanied by some symptoms of cervical spine dysfunction, and the incidence of TMD in the CSD population is also higher, indicating that the two are closely related.

There are many reasons for the pathogenesis of TMD. At present, many scholars have accepted the multi-factor common pathogenic theory, that is, due to the problems or diseases of the dynamic muscles and restrictive ligaments and joint capsules around the temporomandibular joint, the joints are not correct. exercise, resulting in TMD. Among the many pathogenic factors, it is the occlusal factor that dominates.

The jaw position relationship refers to the positional relationship between the upper and lower jaws, whether there is tooth contact or not, the positional relationship between the mandible and the maxilla and even the skull, including three major relationships: the median position, the rest position, and the median position. In the process of oral restoration, digital reconstruction and design of jaw relationship are one of the key steps. Obtaining an accurate jaw relationship can greatly improve the efficiency and quality of subsequent dental restorations.

However, the current method of recording the jaw position relationship is mainly obtained by hand, which is mostly based on experience, lacks precision, and is prone to errors in the process of shifting the jaw position. Specifically, in the current traditional oral restoration, the jaw position relationship is recorded by using the occlusal bracket to determine and record the appropriate height of the lower 1/3 of the face of the recorded person and the supra of the condyles on both sides when the mandibular joint is in the physiological posterior position of the concave joint. Mandibular position relationship, generally need to record the vertical jaw position relationship and the horizontal jaw position relationship, including the following steps: make the occlusal bracket - determine the jaw position relationship - check the jaw position relationship - mark the marking line - fix the jaw position The accuracy of the jaw relationship recording is largely dependent on the operator's clinical experience.

In addition, such as CN106456305B "a recording method and device for jaw position relationship" provides a method to obtain the scan data of the upper and lower jaw, the scan data of the maxillary model and the scan data of the mandible model, and use the common area between the two to obtain The method of three-dimensional scanning data of jaw position relationship requires multiple scanning data, superimposed processing of scanned data, which leads to the defect that once the scanning error is too large, in addition, the acquisition of upper and lower jaw lip and cheek scanning data needs to keep the agreement. The edentulous alveolar ridges of the upper and lower jaws exposed by the scan under the relationship of the jaw position are also difficult to generate, which requires the cooperation of the recorded person and a high level of operation.

The device at least includes: a gum balancer, an occlusal foil, a dental adhesive, a dental impression material, Occlusion recording materials, dental thermoplastic materials, carving knives, recording pens, light-emitting lamps, intraoral scanners.

The steps of the method for obtaining the jaw position after programming the masticatory muscles using the digital gum balancer are as follows:

The gum balancer designed to fit the recorded subject:

Scan the oral cavity of the recorded person, obtain dental data, design and obtain a gum balancer, wherein the gum balancer includes an upper jaw balancer and a lower jaw balancer;

Specifically, in the embodiment of the present invention, a digital intraoral scanner is used to scan the dental data of the recorded person to obtain the upper and lower gum data of the recorded person, and a three-dimensional model of the upper and lower gums is established according to the upper and lower gum shape data. , and design the upper and lower balancers according to the set conditions.

The setting conditions are as follows: the maxillary balancer is designed to cover the width of 1.5-2 cm from the lingual incisal edge of the maxillary teeth of the recorded person to the gum, and the corresponding chinstrap position is a circular plane parallel to the ground plane;

The mandibular balancer is designed to cover the width of 1.5-2cm from the lingual incisal edge of the maxillary teeth of the recorded subject to the gums, and the corresponding lingual frenulum position is a circular plane parallel to the ground plane. A small cylinder is placed on the mandibular balancer, and the diameter of the small cylinder is controlled at 1-3mm, and 2mm is selected in this embodiment.

After obtaining the design models of the maxillary balancer and the mandibular balancer, use the medical resin disc to print the maxillary balancer and the mandibular balancer, and engrave the maxillary balancer and the mandibular balancer by a cutting machine.

Pre-treatment to prepare the gum balancer:

Sterilize the gum balancer, and evenly apply the dental adhesive on the surface of the gum balancer. After the dental adhesive is dry, add the impression material in the same position;

In the embodiment of the present invention, a dental adhesive is applied on the surface of the gum balancer close to the dentition, the dental adhesive is an existing general technology, the impression material is selected as a silicone rubber impression material, and the dental adhesive is adhesive. The impression material and the gum balancer are combined, and the impression material covers the surface of the gum balancer close to the dentition.

Corrected adjustment of the gum balancer:

Place the gum balancer smeared with the impression material on the lingual side of the upper and lower dentition of the recorded person. After the impression material is cured, take it out to obtain the corrected gum balancer. The recorder recorded the upper and lower dentition on the lingual side.

It is worth mentioning that the corresponding upper gum balancer is placed on the lingual side of the upper dentition, and the corresponding lower gum balancer is placed on the lingual side of the lower dentition. After the impression material is naturally cured, it is taken out, and the edge material of the impression material is cut off.

If not, take out the mandibular balancer and make appropriate adjustments. , that is, the size of the cylinder of the designed mandibular balancer is relatively large, if there is a situation that cannot be aligned, the cylinder should be adjusted; The gap should be minimized as much as possible, but there must be a gap of more than 2mm, but only the support positions of the upper and lower balancers are in contact.

Relax the masticatory muscles and check muscle relaxation:

The recorded subject remains in a sitting position, and the recorded subject performs tooth clasping and mandibular movements to relax the masticatory muscles. Check that the masticatory muscles on both sides of the recorded subject are symmetrical and fully relaxed. If yes, continue to the next step. If not, continue to relax the masticatory muscles. .

The role of masticatory muscles on occlusion and occlusion maintenance: As one of the important components of the oral-maxillary system, the functional state of the masticatory muscles directly affects the growth and development of cranio-maxillary occlusion. The strength of masticatory muscle function can change the blood supply and mechanical environment of the craniofacial skeleton on the one hand, and affect the growth pattern of the face. On the other hand, it also affects the balance and stability of the occlusal relationship. Fully relax the masticatory muscles.

In the embodiment of the present invention, when the recorded person maintains the sitting position, it is ensured that the recorded person's hips are slightly higher than the knees. And let the person to be recorded sit opposite the operator, look up, straighten his back, put his feet on the ground, and adjust the height of the chair.

The spearing movement is to let the recorded person do opening and closing movements at a certain frequency within a set time, including small spearing movement, middle spearing movement and large spearing movement, as follows:

Do a small clasp movement: let the recorded person do a clasp movement of about 1CM-3CM, which can be 2CM, about a finger thickness opening degree, and the control time is 8-12 minutes, can be 10 minutes, and 80-10 minutes per minute. 100 times, the frequency can be 90 times, to ensure that the impact sound between the upper and lower gum balancers is heard each time it is closed.

Do the middle clasp movement: let the recorded person do the clasp movement of about 3CM-5CM, which can be 4CM, about 2 finger thickness and opening degree, and the control time is 8-12 minutes, it can be 10 minutes, and every minute is The frequency of 50-70 times, can be the frequency of 60 times, to ensure that the impact sound between the upper and lower gum balancers can be heard each time it is closed.

Do the big buckling exercise: let the recorded person do the buckling movement with the maximum opening degree. At this time, the recorded person can feel the muscles under the chin stretch, about 10-30 times per minute, and it can be 20 times. Frequency, do it about 50 times, and make sure that the head will not move during the movement of the teeth, and only the lower jaw is moving. When closing, let the lower jaw retract naturally and make contact with the upper jaw to ensure that the upper and lower jaws can be heard each time it is closed. Clash between balancers.

The mandibular movement is to pull the mandible of the recorded person in different directions, including forward stretching, leftward pulling and rightward pulling, specifically:

Stretch forward: the subject opens his mouth slightly, stretches his jaw forward, stretches for 2-3 seconds, and then returns to the starting position, repeating 4-8 times, 5 times, 6 times, and 7 times can be selected.

Pulling to the left: the subject's lower jaw is pulled to the left for 2-3 seconds and then return to the starting position. Repeat 4-8 times, 5 times, 6 times, and 7 times can be selected.

Pulling to the right: The subject's lower jaw is pulled to the right for 2-3 seconds and then returns to the starting position. Repeat 4-8 times, 5 times, 6 times, and 7 times can be selected.

It is worth mentioning that, in the embodiment of the present invention, if the masticatory muscles of the recorded person are not relaxed enough, the large buckling movement and the jaw movement are performed again until they are in a relaxed state.

Temporarily fix the occlusal position:

The person to be recorded keeps standing and the teeth are closed. The occlusal recording material is filled on the occlusal surface of the upper and lower posterior teeth of the recorded person. After the occlusal recording material is fixed, it is taken out.
