Pericoronitis

Pericoronitis, also known as third molar pericoronitis, is an inflammation of the soft tissues surrounding an erupting or impacted wisdom tooth (third molar). It is often caused by incomplete eruption or impaction of the wisdom tooth. Clinically, mandibular wisdom tooth pericoronitis is more common. The main symptom is pain.

Dental implant

Dental implant refers to a restoration method in which a biocompatible material (generally called an implant) is implanted into the alveolar bone, and then a denture is made on the implant. Dental implants have independent roots, do not affect other teeth, are relatively strong, have a long lifespan, provide a comfortable oral sensation, can restore chewing function to the greatest extent, and prevent alveolar bone atrophy. The lifespan of dental implants mainly depends on daily maintenance. Currently, domestic and international statistics show that the 10-year survival rate can reach 95% to 96%. Indications With the development of medical technology, the indications for dental implants are becoming increasingly widespread. The main indications include: Patients with missing one tooth, multiple teeth, or even a full arch of teeth. Patients with severe alveolar bone resorption, difficulty wearing traditional dentures, and inability to chew food. Patients with special requirements for the aesthetics and function of dentures. Patients with missing terminal teeth who cannot undergo traditional fixed restorations. Complications Common complications of dental implants include: Wound dehiscence Bleeding or bruising Lower lip paresthesia Sinus membrane perforation Bacterial infection Gingivitis or gingival hyperplasia Progressive marginal bone loss Implant trauma or mechanical fracture of the implant

Orthodontics

Orthodontic treatment primarily uses various corrective devices to adjust the coordination between facial bones, teeth, and the maxillofacial nerves and muscles. This involves correcting abnormal relationships between the upper and lower jaws, between the upper and lower teeth, between the teeth and the jawbones, and between the nerves and muscles connecting them. The ultimate goal of orthodontic correction is to achieve balance, stability, and aesthetics in the oral and maxillofacial system. Theoretically, there is no absolute age limit for orthodontics; anyone can undergo orthodontic treatment at any age.

Oral leukoplakia

Oral leukoplakia is a white lesion that occurs on the oral mucosa. It is a common non-infectious chronic disease of the oral mucosa and can occur on any part of the oral mucosa. This disease is more common in middle-aged and elderly men and carries a risk of malignant transformation, so early attention should be paid.

Impacted tooth

An impacted tooth refers to a tooth that is unable to erupt normally due to an obstruction. The obstruction can originate from adjacent teeth, soft tissues, or bone tissues. The most common impacted teeth are the maxillary and mandibular third molars (wisdom teeth) and maxillary canines. The main symptoms include toothache, gingival swelling and pain, and oral malodor.

Gingival recession

Gingival recession refers to the exposure of the tooth root caused by the apical migration of the gingival margin from the cementoenamel junction, primarily occurring on the labial and buccal surfaces of the teeth. It is common in people over 50 years old, and the typical clinical symptoms include elongated crowns, increased interdental spaces, and exposed tooth roots.

Ankyloglossia

Ankyloglossia, or tongue-tie, refers to a condition where the lingual frenulum does not recede to the base of the tongue after birth, preventing the tongue from extending out of the mouth and the tip from lifting upwards. Symptoms of ankyloglossia include difficulty sucking, slow weight gain, and a "W"-shaped tongue tip when extended.

Temporomandibular joint disorder

Temporomandibular joint disorder (TMJD) is a general term for a group of conditions affecting the temporomandibular joint and/or the masticatory muscle system, causing joint pain, clicking, and limited mouth opening. It is common in adolescents and young adults, primarily presenting as abnormal mandibular movement, pain, clicking, and noises in the temporomandibular joint area. TMJD can be broadly classified into temporomandibular joint dysfunction, temporomandibular joint dislocation, and temporomandibular joint ankylosis.
