Description
Technical Field
The utility model relates to a repositioning jaw pad, relates to the technical field of oral medical appliances, and in particular relates to a digital stable repositioning jaw pad for treating temporomandibular joint disorder.
Background
Temporomandibular joint disorder (Temporomandibular disorders, TMD) is a generic term for a group of diseases whose etiology is not completely understood and which have the same or similar clinical symptoms, and is a clinically common and frequently occurring disease of the stomatology department, mainly including masticatory muscle dysfunction and temporomandibular joint intracapsular disorder. Patients with masticatory muscle dysfunction are mainly manifested as joint pain and masticatory muscle pain; patients with temporomandibular joint intracapsular disorders often experience restorative or irreducible pre-discal displacement, and therefore clinically manifest as mandibular motion abnormalities, pain, ringing or murmurs. When TMD occurs, especially in the growth and development stage of teenagers, the growth and development of the temporomandibular joint condyle are affected, the development of the maxillofacial skeleton is further affected, and if the treatment is not timely carried out, the mandibular retroversion or deflection is easily caused, so that secondary dentofacial and maxillofacial deformity is caused.
The treatment of temporomandibular joint disorders is mainly conservative treatment, usually selected from oral health education, drugs, physiotherapy, jaw pad or surgical methods such as joint cavity lavage, arthroscopic reduction, open surgery, etc. Currently, a relatively effective way to do this is to wear mandibular repositioning jaw pad (Repositioning Splint, RS), which can help the patient to eliminate the ringing and twist lock symptoms caused by the anterior displacement of the articular disc immediately, and Magnetic Resonance Imaging (MRI) also demonstrates that the articular disc can be well repositioned. However, the repositioning area of the repositioning jaw pad in the market is often placed in the anterior dental region, so that the patient often has a larger foreign body sensation and discomfort in the anterior dental region. Furthermore, repositioning the jaw pad does not allow for stable contact of the full dentition, resulting in the jaw pad not helping the patient effectively solve various clinical problems such as temporomandibular joint and masticatory muscle pain. In addition, the existing jaw pad model is designed in a broad spectrum mode according to the conditions of most patients, the occlusion design is single, the manufacturing is inaccurate, and in clinical operation, a doctor is usually required to adjust the jaw pad for multiple times according to the conditions of the patients, and the number of times of patient review is large.
Along with the development of the digital technology and the 3D printing technology, the personalized model or prosthesis can be prepared more accurately and rapidly according to the self condition of a patient by applying the digital technology and the 3D printing technology in clinic, and the prepared model and prosthesis have high anastomosis and good prognosis effect due to individuation, and repeated adjustment and grinding are not needed.
Therefore, there is a need for a non-anterior dental zone repositioning jaw pad that can address the above-mentioned technical problems with a personalized and accurate design, and that achieves a stable contact of the full dentition, effectively solving various clinical problems of TMD patients.

The front and rear parts of the jaw pad body form stable contact of the whole dentition, so that the pain caused by temporomandibular joint disorder can be relieved.
The upper surface of the cuspid-premolaring region retreating control ridge is contacted with the near-middle inclined plane of the first molar of the upper jaw. The canine teeth-premolaring tooth areas on two sides of the lower jaw are retreated to control the ridge to form retention force on the lower jaw, maintain the position of the lower jaw after repositioning, prevent the lower jaw from retreating, and treat the anterior displacement of the joint disc caused by temporomandibular joint disorder.
The thickness of the cheek tongue side of the jaw pad body is 1-1.2mm, the edge is round and blunt, the accuracy is high, the clinical grinding adjustment is less, the foreign body sensation of the patient wearing the pad is small, and repeated grinding adjustment is not needed.
The jaw pad body is made of transparent or semitransparent biocompatible materials, so that the aesthetic degree of the manufactured jaw pad body can be improved, and the material precision of the jaw pad body is higher than 50 mu m.
The beneficial effects of the utility model are as follows:
The utility model adopts the backgrinding control ridge of the premolars area to prevent the mandible from backgrinding, thereby reducing the foreign body sensation of wearing the repositioning jaw pad by a patient; the front and rear parts of the jaw pad form stable point contact of the whole dentition, so that various clinical symptoms caused by temporomandibular joint disorder are effectively relieved; the jaw pad wraps the whole dentition of the lower jaw, 3D digital personalized printing improves the experience and comfort of patient treatment, repeated grinding adjustment is not needed, and the treatment effect is improved.
