Orthodontic Treatment of Unilateral Cleft Lip and Palate Associated with Agenesis of Maxillary Lateral Incisors: A Case Report Cleft lip and palate (CLP) is a common congenital condition presenting significant orthodontic challenges due to maxillofacial growth disturbances, associated malocclusions, and dental anomalies. Patients with CLP often have complex dental and skeletal issues, requiring a comprehensive, interdisciplinary approach to address functional and aesthetic concerns. An 11-year-old female presented with unilateral cleft lip, alveolus, and palate (UCLP) associated with dental anomalies, which included a skeletal Class I relationship with Angle Class II malocclusion, bimaxillary retrognathia, bidental retroclination, negative overjet, lower dental midline shifting, anterior crossbite, microdontia #12, agenesis #22, and several malpositioned teeth. The patient was treated with fixed orthodontic appliances, including the extraction of remaining deciduous teeth, mesialisation of the teeth on the upper left side to close the space resulting from agenesis, and space management in the mandible. Significant improvements were observed in overjet, dental alignment, occlusion, and aesthetics after a 17-month treatment period. Following orthodontic treatment, restorative procedures were performed on teeth #12 and #23. Adhering to the prescribed retainer schedule is essential to preserving dental esthetics and the stability of the treatment results. Comprehensive orthodontic treatment with fixed appliances effectively addressed the complex dental and skeletal issues of this patient with UCLP. The treatment led to improved dental function and aesthetics, highlighting the importance of a personalised approach in addressing cleft cases.

Palatally Displaced Canine and Anterior Crossbite Management with a Combination of Palatal Flap Window and MEAW Technique: A Case Report Canine impaction is a frequent problem, ranking third in occurrence behind the impaction of the mandibular and maxillary third molars. Palatally displaced canines (PDCs) require more omprehensive treatment and are more challenging to manage. This case report describes the management of a rotated palatally impacted permanent maxillary right canine using the open palatal flap window method and the multiloop edgewise arch wire (MEAW) technique. A 19-year-old female patient presented with dental misalignment, which included a skeletal Class I relationship with Angle Class I malocclusion, a protruding lower jaw, anterior crossbite, and the upper left canine being palatally impacted. The panoramic radiograph indicated the existence of a Type II impaction of the canine teeth (Yamamoto classification). The treatment employed the MEAW technique to expand the maxilla and handle an anterior crossbite. The palatal window flap technique was utilized to achieve access to the maxillary right canine by using a button chain and ligation to the upper archwire. The posttreatment outcomes demonstrated satisfactory eruption and alignment of the maxillary right canine, correction of the anterior crossbite at the maxillary right lateral incisor, and realignment of the midline. One year after retention, a satisfactory occlusion was maintained without recurrence of the anterior crossbite. The use of the open palatal window flap technique and button chain application is effective in correcting PDCs and achieving adequate tooth alignment within the dental arch.

Skeletal Class III malocclusion treatment is complex, especially when jaw deviations are serious. Camouflage treatment of skeletal Class III malocclusion improves prognosis with a slight-to-moderate functional shift. This report presents the case of a 23-year-old male with poor facial esthetics associated with chin protrusion and an uncomfortable bite. He had a concave profile, unfavorable incisor displays, protrusive lower lip, and strained lip closure. Camouflage therapy with a passive self-ligating (PSL) system through the anterior teeth of the maxilla protraction and arch expansion was used. After 14 months of treatment, the overjet outcome was positive. The teeth were arched, asymmetry was addressed, the convex profile and no deviation occurred when the jaw was closed. Factors in using the PSL system were low friction between the bracket and archwire, torque selection, and the significant dental arch expansion ability. The PSL system is an appropriate option in treating adults with skeletal Class III malocclusion to achieve a normal occlusion and a pleasant facial profile.

ABSTRACT The goal of this study was to investigate differences in alkaline phosphatase (ALP) levels in young and old rabbits after administering the soybean isoflavone genistein during orthodontic tooth movement. Twelve rabbits were used and assigned to four groups (n = 3); OG (old rabbits), OGS (old rabbits + soybean), YG (young rabbits), and YGS (young rabbits + soybean). The rabbit mandibulary incisors were distalised using a nickel-titanium open coil spring (50 g force). Genistein was administered from the initial orthodontic force delivery until day 21, at a dose of 1.2 mg/kg BW once a day. ALP levels (U/mg) were measured on days 1, 7, 14, 21 after orthodontic force delivery using a UV-Vis 6300 spectrophotometer at a 405 nm wavelength. The results were analysed by one-way analysis of variance followed by Tukey’s Honest Significant Difference (HSD) test (p < 0.05). The ALP levels between the young and old age groups were significantly different. ALP levels were highest in the YGS group, and significantly lowest in the OG group (p < 0.05). Moreover, the ALP level of the OGS group was significantly higher than that in the OG group (p < 0.05). In conclusion, daily consumption of soybean isoflavone genistein could enhance ALP levels during orthodontic tooth movement, particularly in older rabbits.
