Introduction and indications of stable occlusal splint

The stable bite plate covers the entire arch surface, and the surface is smooth and flat, which is convenient for free adjustment of the jaw position. The stable bite plate can eliminate the instability factors between the occlusion and the jaw position, and at the same time eliminate the harmful effects of the pathogenic factors of the temporomandibular joint disorder. After the symptoms are eliminated, the height of the occlusal surface of the bite plate can be gradually reduced until the occlusion The surface is worn through, and finally the early contact of the natural teeth is adjusted to keep the muscle position consistent with the tooth position. If a stable bite plate is used as a long-term treatment, it should be evaluated regularly and adjusted according to the needs of restoration, orthodontics, or other treatments.

The stabilizing bite plate can be used for the upper jaw or the lower jaw. It is generally used on the side where the occlusal disorder is more obvious, but the upper jaw is more used. The application of a stabilizing splint in the upper jaw has good retention and stabilization effects. It is easy to achieve point-like contact with the jaw teeth, facilitate the formation of a stable positional relationship between the articular socket, the articular disc and the condyle, and it is also convenient for the doctor to adjust it, but it is worn After affecting the appearance and pronunciation. The mandibular stabilization splint is comfortable to wear, and has little effect on the patient's pronunciation and aesthetics, but it is not easy to achieve proper anterior tooth contact and convenient incisor-guide relationship, and it is difficult for beginners to grasp.

1. Indications

A stable bite plate is usually used to treat hyperfunction, muscle spasm, and adjustment of jaw relationship; it can also be used to reduce pressure-related side-function activities such as clenching and night bruxism; it has localized myalgia or chronic central mediation Patients with myositis can also be treated with this method; it also has a certain effect on the inflammation of the posterior disc tissue secondary to the trauma, which is beneficial to the healing of the wound tissue.

2. Bite requirements

After putting on the bite plate, all supporting spires are required to maintain simultaneous, extensive and uniform point contact with the bite plate, and the front teeth are in a light contact state. During the protruding movement, the incisors should be evenly contacted, and the incisor guide should not be too large. It is advisable that the central fossa of the first molar can be separated by 1~2mm; during lateral movement, keep the canine in contact with the occlusal plate to form a canine guide . The surface of the occlusal plate should be as flat as possible without obvious apex locking.

3. How to use

According to different treatment types, instruct patients to wear a stable bite plate. Patients with myogenic pain and bruxism mainly wear it at night, and patients with inflammation of the posterior disc tissue, intra-articular dysfunction, and transitional treatment of occlusal reconstruction should wear it all day. During the wearing of the bite plate, the patient should be instructed to maintain good oral hygiene, keep the bite plate clean and how to store the bite plate. If the pain worsens after wearing the bite plate, stop wearing the bite plate and re-evaluate and adjust the bite plate.
