This case report documents the diagnosis and successful management of a substantial periapical lesion located in the lower left region of the jaw. The patient presented with clinical symptoms indicative of periapical pathology, and radiographic examination revealed an extensive radiolucent lesion. The chosen treatment approach involved endodontic intervention coupled with surgical decompression, leading to the resolution of the lesion and restoration of oral health. This case underscores the significance of an accurate diagnosis and a multidisciplinary treatment approach in addressing large periapical lesions.

Anterior open bite and transverse discrepancy are often accompanied by hyperdivergent skeletal patterns. In addition, degenerative joint disorders and vertical maxillary excess contribute to an unfavorable convex facial profile with a retruded chin. Correction of this complex three-dimensional problem with orthodontic treatment alone is considered challenging owing to anatomical limitations. Moreover, a history of orthodontic treatment with premolar extraction makes retreatment difficult. This case report illustrates the application of a maxillary tissue bone-borne expander and biocreative reverse curve system in a 23-year-old female patient with a severe anterior open bite and transverse discrepancy who underwent orthodontic treatment with four premolar extractions. By setting the treatment target under precise diagnosis and using appropriate appliances, a satisfactory treatment result could be achieved without orthognathic surgery.

This report describes the case of a 12-year-old female patient with a long mandible experiencing difficulty chewing with the right molar. Considering the age of the patient, bone-anchored maxillary protraction using four miniplates placed below the maxillary zygomatic arch and anterior symphysis of the mandible and Class III intermaxillary elastics were planned. After 12 months, orthodontic treatment was initiated. After extraction of the impacted maxillary right second premolar and mandibular right second primary molar, protraction of the mandibular right molars was performed using a miniplate placed on the anterior part of the mandible as an anchor. Miniscrews were placed in the left posterior part of the mandible to improve the molar relationship and correct the dental midline through distalization of the mandibular left posterior teeth. We reported successful sequential comprehensive nonsurgical treatment in an adolescent with skeletal Class III malocclusion.

BACKGROUND: Although external penetrating laryngeal trauma is rare in the clinic, such cases often result in a high mortality rate. The early recognition of injury, protection of the airway, one-stage laryngeal reconstruction with miniplates and interdisciplinary cooperation are important in the treatment of such patients.
METHODS: A 58-year-old male worker sustained a penetrating injury in the left neck. After computed tomography scanning at a local hospital, he was transferred to our hospital, where he underwent tracheotomy, neck exploration, extraction of the foreign object, debridement and repair of the thyroid cartilage using titanium miniplates. An endo laryngeal stent was inserted, which was removed 12 days later. The patient recovered well and his voice rapidly improved after surgery.
CONCLUSIONS: Penetrating laryngeal trauma is uncommon. We successfully treated a patient with early laryngeal reconstruction and management by interdisciplinary cooperation.

OBJECTIVE: Miniplates were initially developed as targets for foot and hand fractures, but they have been used in the treatment of fixation of small bone fragments, reduction of long bone fractures and non-union treatment, which have been difficult to treat. In this study, the authors used miniplates to treat fractures of the upper extremities, lower extremities, and pelvis obtained good outcomes. Herein, the authors report these good outcomes and review the current concept of miniplates.
METHODS: Forty-two patients treated with miniplates between March 2012 and March 2017 who attended follow-up for > 1 year were included in this retrospective study. Miniplates were selected according to purpose, which was classified into three categories: fixation, reduction, and stability enhancement. For fixation, miniplates were used to fix distal fibular fractures occurring distal to the syndesmosis and treat patellar and olecranon fractures with severe comminution. For reduction, miniplates were used to reduce the tibia during intramedullary nailing in tibiofibular shaft fractures, while reduction was performed in advance of definitive plating fixation in patients with humeral and pelvic fractures. To enhance stability, the miniplate was inserted after autobone graft for atrophic nonunion at the humeral shaft following nail insertion. The validity of a miniplate was analyzed by reviewing the published literature on the use of miniplates in orthopedic fracture surgeries.
RESULTS: Bony union was achieved in all cases. No specific postoperative complications were observed; however, mild pain and limited range of motion observed in two patients were resolved after implant removal. Sixteen studies on fracture treatment using miniplates reported clinically fair outcomes.
CONCLUSIONS: Miniplates are not just small metal plates. Depending on the location and treatment of the fracture, the miniplate can effectively fix small bone fragments, help the main plate to maintain the reduction of large bone fragments, and increase the fixation force for nonunion treatment.

OBJECTIVE: This case report aims to demonstrate the successful utilization of zygomatic miniplates in the treatment of an adult patient with anterior open bite (AOB).
BACKGROUND: During treatment of anterior open bite, incisor extrusion may compromise facial esthetics in cases with long facial height and/or sufficient incisor exposure at rest and smile.The intrusion of posterior teeth has the advantage of correcting vertical dimension and maintaining proper incisors show.
METHODS: The patient, a 22-year-old boy, had an anterior open bite of 4.5 mm with increased lower facial height, bilateral posterior crossbite, and two different occlusal planes in the upper arch. Titanium miniplates were used to intrude maxillary posterior teeth with a transpalatal arch appliance to limit buccal tipping.The intrusive force was then applied through elastomeric chains placed bilaterally in the maxillary arch between the miniplate and posterior teeth.The anterior open bite was corrected within 7 months of intrusion with decreased lower facial heightand significant improvement in anteroposterior jaw relationship.
CONCLUSIONS: This report emphasizes the significant role of facial appearance and smile.
CONCLUSIONS: Most of the non-surgical approaches are not suitable for open bite correction in cases with long facial height and/or sufficient incisor exposure at rest and smile because of their extrusive mechanics which compromise the facial and smile esthetics. The intrusion of posterior teeth using min iplates allowing a counterclockwise rotation of the mandible to correct anterior open bite without compromising facial esthetic and smile.
