Unicystic ameloblastoma is generally less aggressive and has a lower recurrence rate than solid or multicystic ameloblastomas, making it more amenable for conservative treatments such as enucleation or curettage. However, in case of large cysts, accurate diagnosis can be challenging depending on the location of biopsy. If unicystic ameloblastoma is misdiagnosed as other odontogenic or inflammatory cysts, the risk of postoperative recurrence increases. In this paper, we report a case of early recurrence following decompression and enucleation of a large maxillary unicystic ameloblastoma.

Facial burns in infant can disrupt maxillofacial growth, leading to deformities and functional impairments. These burns, often occurring in children aged 8–13 months, may result in malocclusion and facial asymmetry caused by altered neuromuscular development. The historical principles of maxillofacial burn management have been established by pioneers such as Kazanjian and Hyslop. In 1849, Simon P. Hullihen performed the first documented orthognathic surgery for a burn-induced deformity on a young patient with mandibular prognathism. In the present study we discuss a similar case involving a 10-year follow-up, demonstrating the use of virtual surgical simulation in evaluating and treating maxillofacial deformities resulting from electrical burns in children.

In cases of complete cleft lip with an absent nasal floor, reconstructing the mucosal lining of the nasal floor and the intraoral cleft gap is critical for a successful cheiloplasty. The inferior turbinate flap has been proposed as an option for nasal floor reconstruction, with various technical strategies available. This article presents three cases of cheiloplasty utilizing the inferior turbinate mucosal flap to line wide cleft gaps. By employing the inferior turbinate flap, the nasal floor can be reconstructed effectively without leaving raw surfaces.Thus, the inferior turbinate mucosal flap is a valuable technique for nasal floor and intraoral lining reconstruction, particularly in cases with a very wide cleft gap.

Synovial sarcoma is a rare malignant tumor that occurs in the oral and maxillofacial regions, particularly in the mandible. Herein, we report a rare case of biphasic synovial sarcoma of the mandible in an 82-year-old man. The patient was referred with chronic diffuse painful swelling in the right mandible and underwent local resection of the right mandible. Computed tomography revealed severe destruction of the mandible. An initial biopsy revealed osteomyelitis of the jaw. However, immunohistochemical staining and genetic analysis confirmed synovial sarcoma, and the patient underwent additional resection of the mandible. The histological features are described, and the differential diagnoses are discussed.

Cleidocranial dysplasia is a rare genetic disorder characterized by a congenital autosomal dominant condition. It leads to hypoplasia of the clavicles, abnormal formation of the teeth, and issues with skeletal and craniofacial bones. This condition is caused by a mutation in the Runt-related transcription factor 2, which is essential for the formation of teeth, cartilage, and bone. Patients with cleidocranial dysplasia exhibit typical polyostotic features, including underdeveloped clavicles, delayed closure of cranial fontanels and sutures, multiple woven bones in the skull, and dental anomalies such as failure of permanent tooth eruption, lack of deciduous tooth resorption, and multiple impacted and supernumerary teeth. This article presents a case of cleidocranial dysplasia in a 22-year-old female patient, aiming to highlight the clinical and radiological aspects of diagnosis.

This case report presents a treatment for a patient with idiopathic condylar resorption, characterized by mandibular condyle resorption, skeletal Class II malocclusion, and an open bite. The patient underwent total temporomandibular joint (TMJ) replacement to improve TMJ function and enhance facial aesthetics, as well as to extrude the lower posterior teeth to maintain the increased vertical dimension of occlusion. These procedures successfully replaced the mandibular condyle and fossa with TMJ prosthetics, stabilizing jaw function and allowing for improved occlusion. This report discusses the considerations and stability associated with TMJ replacement in a patient with idiopathic condylar resorption.

This case report describes mandibular reconstruction using a deep circumflex iliac artery (DCIA) flap, incorporating virtual surgical planning and 3D-printed surgical guides, following tumor resection. A 49-year-old male presented with an ulcerative lesion in the left posterior mandible. Following a diagnosis of squamous cell carcinoma (pT4aN2bM0), selective neck dissection (level I–IV) and segmental mandibulectomy were performed. Virtual surgical planning based on computed tomography images enabled the creation of patient-specific surgical guides. Reconstruction of the mandible and soft tissue was achieved using a DCIA flap that included the internal oblique muscle. The procedure lasted 605 minutes, with an ischemia time of 43 minutes. During a one-year follow-up, no complications or recurrences occurred, and functional and aesthetic outcomes were satisfactory. DCIA flap reconstruction with virtual surgical planning and custom surgical guides demonstrates effectiveness as a treatment for extensive mandibular defects.

This report presents the case of severe tooth wear and vertical dimension loss in a 71-year-old male patient. A combined conventional and digital approach was employed for full-mouth rehabilitation. After determining an increase in the vertical dimension of 5.5 mm using an anterior jig and diagnostic wax-up, provisional restorations were fabricated and adjusted throughout the adaptation period.For the fabrication of the final prosthesis, digital methodologies such as oral scanning and occlusal acquisition were performed. To obtain precise margin data, a die model was fabricated using the traditional impression method, followed by model scanning, which was then combined with intraoral scan data. The final prosthesis was made of zirconia to enhance esthetics and strength. Consequently, the treatment enhanced both function and esthetics, leading to high patient satisfaction with the outcomes.

This study evaluated the long-term stability and efficacy of occlusion achieved by setting a normalized chewing position as the therapeutic position in patients with abnormal chewing positions due to tooth loss or malocclusion. Furthermore, the study monitored the recovery rate of the stomatognathic system. Sixteen patients undergoing oral functional rehabilitation participated in the study, utilizing an intraoral Gothic arch tracer to normalize abnormal chewing positions and designate the apex of the resultant chewing patterns as the therapeutic position. The first set of data was gathered during occlusal reconstruction at the point when a therapeutic position was necessary, and the second set was collected approximately 10 years later under the same conditions. Four mandibular movements—chewing movements for hard food (CM-H), chewing movements for soft food (CM-S), border movement (BM), and maximum intercuspation position (MICP)—were compared to assess the long-term stability between the chewing position and occlusion and the recovery rate of the stomatognathic system. The findings showed a 63% concordance between CM-H and MICP, confirming the long-term stability of both the chewing position and occlusion. Furthermore, the concordance between CM-H and CM-S increased by 13%, whereas the alignment between the chewing position and BM increased by 25%. In summary, the concordance across all four movements improved by 19%, demonstrating increased long-term recovery rate of the stomatognathic system. These findings provide clinical evidence that occlusal reconstruction centered on the chewing position offers long-term stability and recovery. By establishing an efficient occlusion that harmonized with the chewing patterns, this approach compensates for age-related declines in chewing function and helps maintain the stomatognathic system health.
