Summary: This study found significant differences in dentoskeletal characteristics between adults with unilateral posterior crossbite and those with normal occlusion. The maxillary posterior teeth were more buccally inclined and the mandibular posterior teeth were more lingually inclined in the crossbite group. In contrast, on the non-crossbite side, both maxillary and mandibular posterior teeth were lingually inclined.

Summary: This study aimed to evaluate posterior vertical mandibular asymmetry in different types of malocclusions by calculating the mandibular asymmetry index on panoramic radiography. It also considered sexual dimorphism in children and adolescent patients and compared the results between different groups. A total of 214 patients (134 females and 80 males, mean age of 9.5 ± 2 years) were included in this cross-sectional study. The results showed significant differences between males and females in the condylar index and significant differences in unilateral posterior crossbite. No significant differences were found in the mandibular ramus and condyle-plus-ramus index between males and females. The highest asymmetry index was observed at the level of the condyle, and higher values of asymmetry were found in Angle Class I malocclusions in all groups and Class II/1 malocclusions in females.

Summary: Currently, the diagnosis of transverse growth deficit of the maxilla relies on the experience of a clinician, lacking objective criteria. This study aimed to establish a mathematical method for diagnosing maxillary compression based on skull and mandible dimensions. The study analyzed records of 97 cases and found that cranial width measurements can predict the group to which each subject belongs. A logistic regression formula based on cranial, maxillary, and orbital widths was obtained, allowing for the diagnosis of maxillary compression with high sensitivity and specificity.

Summary: This study investigates the association between UPC with functional shift and reverse chewing pattern as well as altered spine flexion. The results indicate that UPC patients have a higher percentage of anomalous/reverse chewing patterns on the crossbite side and show a clear difference in flexion angles of the spine between left and right sides, with the crossbite side being more flexible. These findings contribute to a better understanding of the association between dental malocclusions and spine posture, and may aid in diagnosis and treatment strategies.

Summary: This study aimed to explore the inclination of the lower central incisor and symphysis in alveolar bone in severe skeletal class III patients. A total of 198 patients were divided into three groups based on the mandibular plane angle. The results showed that there were no significant differences in the angle between the long axis of the mandibular symphysis and the long axis of the lower central incisor among the groups, while significant differences were found in the angle between the axis of the lower incisor and the mandibular plane. The study concluded that the mean MIA reflects the physiological inclination of the lower central incisor better than the IMPA.

Summary: This study investigated the asymmetry of hard and soft tissues in skeletal Class III patients and explored the relationship between menton deviation and bilateral differences in tissue prominence and thickness. The results showed significant differences in tissue prominence between the deviated and non-deviated sides in the asymmetric group, while no significant differences were observed in tissue thickness except at one point. The study suggests that soft tissue thickness may not influence overall asymmetry in the presence of hard tissue asymmetry.

Summary: This case report describes the non-surgical orthodontic camouflage treatment of a male patient with skeletal Class III asymmetry and severe anterior open bite. The treatment involved extrusion of the maxillary and mandibular anterior teeth, rotation of the occlusal plane, and distalization of the mandibular dentition. The patient's smile esthetics and facial profile were improved, and facial asymmetry was slightly alleviated after 15 months of treatment.

Summary: Postsurgical relapse at B-point may occur gradually over time and is mainly due to condylar resorption in mandibular advancement patients. Mesial yaw of the condyle during surgery may result in condylar resorption postsurgically. Additionally, females are at greater risk of condylar resorption after surgery.

Summary: This study evaluated postsurgical condylar remodeling, condylar volumetric asymmetry, and soft tissue symmetry after unilateral high condylectomy and bimaxillary osteotomies. Radiographic signs of degenerative changes were noted in both surgical and nonsurgical condyles, with an average volumetric improvement of 531.9 mm(3) and soft tissue symmetry improvement of 65.8%. Despite remaining joint asymmetry, soft tissue correction was stable 1-year post-surgery.
