Gnathology

Gnathology is a branch of dentistry that studies the function of the temporomandibular joint, bite, masticatory muscles, and the entire dental system. When their interaction is disrupted, pain, clicking, fatigue during chewing, facial muscle tension, headaches, or tooth wear may occur.

To eliminate these manifestations, it is important to first precisely determine their cause. At the Dobrobut Dental Clinic, treatment begins with diagnosis, after which the doctor develops an individual therapy plan: splints, myofunctional therapy, bite correction, etc.

How a Gnathologist Consultation Proceeds

During the consultation, the doctor checks the condition of the temporomandibular joints, bite, tone of the masticatory muscles, neck and shoulder muscles, and also assesses the condition of the spine. An imbalance in the dental system can lead to various complications such as bruxism, restricted jaw movement, clicking or pain in the joints, headaches, enamel wear, bite disorders, and other problems.

Thus, the main task is to identify the cause of these disorders to restore muscle balance and full functionality of the dental system through appropriate treatment. During therapy, patients report the disappearance of pain symptoms, facial muscle spasms, and other unpleasant manifestations of dysfunction in the temporomandibular joints.

Symptoms and Indirect Signs of Jaw Joint Problems

Disruptions in the function of the temporomandibular joint do not always manifest only as jaw pain. Sometimes a patient spends years treating headaches, neck discomfort, tinnitus, or muscle tension, unaware that the cause may lie in incorrect tooth closure or joint overload. A consultation with a gnathologist helps to clarify why the jaw clicks, pops, “locks,” hurts during chewing or talking, gets tired quickly, and experiences stiffness in the morning.

It is also worth paying attention to teeth grinding during sleep, severe enamel wear, chips in fillings or crowns, and the feeling that the teeth interfere with one another. A separate reason to consult a specialist is discomfort after installing a filling, crown, veneers, implants, or starting orthodontic treatment.

Major Causes of TMJ Dysfunction

TMJ dysfunction usually does not arise suddenly. It is often the result of prolonged overload of the jaw joint, improper distribution of masticatory load, or changes in bite. Sometimes the problem develops gradually: after tooth loss, an unsuccessful filling, improperly fitted crowns, or treatment. As a result, the jaw begins to shift, muscles become overstrained, and the joint does not function as it should.

Key causes of TMJ dysfunction include:

• incorrect bite or congenital anomalies in jaw structure;
• tooth loss without subsequent prosthetics;
• fillings, crowns, veneers, or implants that disrupt the proper closure of teeth;
• inadequate orthodontic treatment;
• bruxism and the habit of tightly clenching teeth;
• facial, jaw, neck, or spinal injuries;
• muscle spasms, stress, and chronic tension.

That is why treatment must start with determining the causes of these disorders.

Diagnosis during a Gnathologist Appointment: What the Doctor Checks

During the initial consultation, the following procedures are performed:

• collecting complaints, medical history;
• extraoral examination;
• assessing facial symmetry, amplitude of lower jaw movements when opening the mouth;
• palpation of the masticatory muscles;

Intraoral examination:

• assessing bite;
• edentulism;
• signs of bruxism;
• tooth wear;
• identifying other factors that may affect the state and function of the TMJ.

Referrals for consultations with related specialists (if needed):

• otorhinolaryngologist consultation.
• rheumatologist consultation.
• neurologist consultation.
• vertebrologist consultation.
• oral and maxillofacial surgeon consultation.

Instrumental and Digital Diagnostics: CT, MRI, and Axsiography

Before starting treatment, the doctor must precisely determine what disrupts the function of the TMJ. A regular examination is often insufficient for this, so gnathology employs instrumental and digital diagnostics. This helps to assess not only the condition of the teeth but also the function of the joint, muscles, and jaw in movement. This allows for the development of an accurate and safe treatment plan.

Among the auxiliary diagnostic methods, the following are used:

1. CT of the facial skeleton.
2. MRI of the TMJ open/closed mouth.
3. Photodiagnostics.
4. Axiography.
5. Myography.

Computed tomography of the jaw helps assess the bony structures, the position of the condylar heads, and the jaw structure. MRI of the TMJ in open and closed mouth positions shows the condition of soft tissues, the articular disc, and ligaments. Axiography records the movements of the lower jaw during mouth opening, closure, and chewing, to identify dislocation or blockage of the joint. Myography assesses the tension of the masticatory muscles, while photodiagnostics evaluate facial symmetry and jaw position.

Computer Analysis of Occlusion using T-Scan

T-Scan is a digital diagnostic method that helps to assess how the teeth come together and how the masticatory load is distributed. Unlike conventional reproduction paper, the system shows not only the contact areas but also the force, sequence, and symmetry of occlusion in real time. This allows for the identification of overloaded areas, premature contacts, imbalances between the right and left sides, and factors that may provoke joint pain, tooth wear, or discomfort after fillings, prosthetics, or orthodontic treatment. The gnathologist prescribes T-Scan for accurate occlusion assessment and further planning of bite correction.

How Gnathological Treatment Proceeds

Therapy begins with identifying the cause of the disorder. The gnathologist becomes familiar with the patient's complaints, bite condition, functioning of the temporomandibular joint, tone of the masticatory muscles, and diagnostic results. Following this, they develop an individualized plan, which includes:

1. Initial consultation, examination, and functional tests.
2. Digital diagnostics as indicated: CT, MRI, T-Scan, axiography.
3. Creation of an individual joint splint or device.
4. Follow-up visits and treatment adjustments.
5. Further orthodontic, orthopedic, or therapeutic rehabilitation. If bite correction is needed after the gnathological phase, the doctor may recommend braces or aligners.

Splint and Splint Therapy for Muscle Relaxation

A joint splint, or splint, is an individual device for normalizing the position of the lower jaw and reducing the overstrain of the masticatory muscles. It is used for TMJ pain, clicking, bruxism, jaw stiffness, tooth wear, or muscle spasms.

The splint is fabricated after diagnosis, so the gnathologist's appointment includes assessment of the bite, jaw movements, and joint function. Typically, splint therapy lasts from 3 to 12 months and requires follow-up visits for adjusting treatment.

Questions and Answers

How does a gnathologist differ from a regular dentist?

A regular dentist treats teeth and gums, while a gnathologist assesses the function of the entire stomatognathic system: bite, temporomandibular joint, masticatory muscles, and movements of the lower jaw.

Can jaw clicking be treated with a splint?

Yes, in many cases, a joint splint helps reduce clicking, relax muscles, and stabilize the position of the lower jaw. However, it is prescribed only after diagnosis.

How long does a course of gnathological treatment last?

Typically, joint therapy lasts from 3 to 12 months. The duration depends on the cause of the TMJ dysfunction, the state of the bite, muscle tone, and the patient's response to treatment.

Is it necessary to do a CT or MRI before an appointment?

No, not always. Initially, the doctor conducts an examination, assesses complaints, the bite, and jaw function. CT, MRI, T-Scan, or axisography are prescribed only when indicated.

Should one visit a gnathologist before getting braces or veneers?

Yes, it is advisable, especially if there is pain, clicking, tooth wear, bruxism, or discomfort when biting down. Gnathology is a treatment that helps to properly prepare the stomatognathic system before orthodontics, veneers, or prosthetics.
