Dislocation of the lower jaw - causes, symptoms, diagnosis and treatment

Structure

The formation of the mandibular region is the result of the evolution of the human body. In the process of development, the entire structure became mobile and autonomous, gaining the ability to move freely and perform the basic functions necessary for a person. The temporal joint is localized in the fossa, connecting to the bony part.

When a subluxation occurs, the head of the joint partially comes out of the fossa, succumbing to the influence of external factors. As a rule, this phenomenon becomes a consequence of a general weakening of the ligaments or disturbances in the articular cavity. If you have the proper skills and practical experience, you can restore the original position of the jaw yourself, but the systematic occurrence of such a problem is the basis for complex treatment.

Complications

If the patient promptly sought medical help and strictly followed the recommendations while wearing the splint, then the outcome is favorable. In this case there should be no relapses. But early load on the jaw and the presence of deforming joint diseases can provoke a relapse, and, as a rule, more than one.

Causes and classification

Displacement of the lower jaw is the result of the application of an external force that exceeds in intensity the force of natural fixation. For each person, such a threshold is individual - some patients may suffer from minor force, while others are able to endure strong mechanical impact without consequences.

The main factors determining the tightness of the fit are ligament tension and bone attraction. The weakening of these connections can provoke the occurrence of subluxation, both one-time and in a chronic form. The reasons that negatively affect the condition of the jaw region include:

Advanced stages of rheumatism;
Developing arthritis or osteomyelitis;
The occurrence of cramps and muscle spasms;
Consequences of encephalitis;
Epileptic seizures.

They also note the existence of traumatic factors, the occurrence of which can cause subluxation:

Mechanical injuries - impacts, collisions;
Excessive opening of the mouth;
Having bad habits;
Congenital abnormalities that affect the formation of the articular fossa.

The classification used in dentistry differentiates pathology according to the following criteria:

Based on the position of the articular head - anterior, posterior and lateral subluxation;
According to the specificity of the displacement - one-sided and two-sided form;
Depending on the severity - for simple and complex cases.

The choice of technique, as well as the timing of treatment, depend on the original source of the problem. It is easiest to cure the pathology in the early stages, so at the first symptoms of subluxation it is recommended to consult a doctor and undergo an examination.

Clinical manifestations

Symptoms depend on the type of dislocation. Common manifestations include:

difficulty closing and opening the mouth;
protrusion or distortion of the jaw forward;
sharp pain radiating to the temple;
profuse drooling;
inability to pronounce words normally.

Treatment of habitual jaw dislocation should be carried out exclusively by a specialist. The only thing the patient can do is fix the position by bandaging his chin with a scarf. Painkillers and ice will help reduce pain.

Symptoms and signs

For each form of subluxation, there are characteristic individual signs that indicate the presence of deviations. However, there are a number of universal symptoms observed in all types of pathology:

The occurrence of pain of varying severity, aggravated when the patient attempts to move the lower jaw;
Limited mobility of the temporomandibular joint, making it difficult to perform usual actions - eating or speaking;
Active secretion of saliva associated with a swallowing problem.

In addition, with bilateral dislocations affecting the anterior zone, the following circumstances occur:

Inability to close the jaws, forcing the patient to keep his mouth open;
Pain in the skull and swelling of tissue in the ear area;
Partial or complete dysfunction of the speech apparatus.

The unilateral form of subluxation has similar symptoms, but allows partial closure of the mouth, which significantly alleviates the patient’s problems. In turn, posterior bilateral subluxation is characterized by the opposite symptomatology - the inability to open the jaw, pressing of the lower part into the larynx area.

First aid and treatment

If a subluxation occurs, it is recommended to straighten the jaw using the infiltrative or guide method, after first calming the patient and giving him an anesthetic. The lack of such skills requires contacting a qualified orthodontist, who will not only restore the natural structure of the jaw apparatus, but also advise measures aimed at restoring and preventing recurrences. If the procedure aimed at realigning the joint is carried out in a timely manner, as well as medical recommendations are followed during the rehabilitation period, the prognosis for a complete cure is very favorable.

Treatment

Only a doctor should correct a dislocation. Self-medication will only worsen an already difficult situation.

After examining the patient and receiving the X-ray results, the doctor will reduce the dislocation using one of the following methods, namely:

Blechman-Gershuny method;
Popescu method;
Hippocratic method;
Holorovich method.

How to set a dislocated jaw using the Hippocratic method. The patient is seated on a chair so that the back of his head rests against the back. The patient's lower jaw is at the level of the doctor's elbow. The surgeon wraps his thumbs with cloth and places them on the patient's molars. The remaining fingers grasp the lower part of the patient's chin. After this, the doctor lifts the chin and moves the jaw down and back. This way the head falls into place. After this, a special fixing splint is applied to the jaw. The patient must wear this bandage for at least 10 days. In addition, doctors recommend abstaining from solid foods during treatment. Porridge, pureed soups, vegetable puree are the basis of the diet. You cannot open your mouth wide, shout or eat in large quantities.

The doctor will tell you whether you can dislocate your jaw when yawning during your consultation.

My brother somehow had a dislocated jaw. He said it hurt terribly! But can there be relapses?

I constantly feel that my jaw seems to be overstrained; sometimes there are clicks on one side. I contacted a therapist. The doctor did not take an x-ray, but felt and determined a slight inflammation. He only prescribed ibuprofen, and said everything else would go away on its own. But I don’t understand how the medicine will help relieve tension in the jaw?

Group No. 5: acute and old

If the dislocation or subluxation of the jaw is fresh, that is, it occurred quite recently, then symptoms such as pain and malaise appear clearly, and doctors speak of an acute form.

It’s hard to believe, but there are situations when, when injured, the patient is in no hurry to seek professional help. Either first aid was unqualified and the treatment of acute dislocation was carried out incorrectly. In all of these cases we are talking about old dislocations. Only a few correction methods are suitable for their reduction, which are very painful and require long-term rehabilitation.

What type of dislocation a particular person has can only be told by a doctor who will make an accurate diagnosis based on a visual examination and using radiography, which allows one to determine the extent and extent of the problem, as well as to exclude the presence of fractures and cracks in the jaw bone.

The type of dislocation can only be detected on an x-ray

Causes of jaw dislocation

Dislocation of the lower jaw can occur as a result of screaming, strong yawning, while eating or vomiting, that is, in those moments when the mouth opens sharply and widely (trying to bite off too large a piece of food can also cause jaw dislocation.). Bad habits of opening bottles or packages with your teeth can also cause harm, excessively straining your jaw.

There are frequent cases of its damage as a result of a strong blow. Professional athletes - wrestlers and boxers - face dislocation of the lower jaw. You can cause displacement of the articular head by chewing too hard and tough food, for example, nut shells. To protect your jaw from damage, you should avoid too sudden and rapid movements while yawning and chewing.

Dislocation of the lower jaw can also be non-traumatic. For example, some diseases, including rheumatism, gout, osteomyelitis, poliomyelitis, arthritis or arthrosis, cause relaxation of the ligaments, as a result of which the height of the joint decreases and its shape is deformed.

In women, due to the shallower depth of the articular fossa, it is easier to displace the head of the joint. Accordingly, jaw dislocation occurs much more often in them than in men.

Independent actions

When a jaw is dislocated, a person should not make sudden movements. Severe pain is relieved with analgesics. In this case, the victim must know for sure that there is no allergy to the medication. Trauma is often accompanied by increased blood pressure. If the indicator increases significantly, you should take a drug that normalizes blood pressure.

Independent actions when realigning the jaw:

Fixation of the jaw in one position using available means or a splint.
Place a bandage in the mouth that will absorb the saliva that is produced.
Call an ambulance. If the victim cannot speak, then he needs to ask neighbors or passersby for help (if the dislocation occurred on the street). If there is a clinic near the scene of the incident, you should go there immediately.

Before receiving qualified medical assistance, you should say as little as possible, since any movements can cause pain or complications of the dislocation. It is not advisable to adjust the joint yourself. Illiterate actions can lead to damage to the helping fingers or long-term dysfunction of the jaw apparatus in the victim.
