This case report describes the use of a miniscrew-assisted rapid palatal expander and aligners to correct bilateral cross-bite and crowding in an adult patient with a Class III skeletal pattern. A digitally designed surgical guide was three-dimensionally printed and used to accurately insert four miniscrews into the palate; these were employed to anchor a novel miniscrew-assisted rapid palatal expander appliance without any dental anchorage. Cone-beam computed tomograms before and after miniscrew-assisted rapid palatal expander treatment demonstrated the orthopedic expansion of the maxilla without dental tipping. The patient was then fitted with aligners to correct crowding and malocclusion. This case report demonstrates the successful treatment of an adult patient with a narrow maxilla and bilateral cross-bite using a nonsurgical, conservative treatment.
Surgically assisted rapid palatal expansion to correct maxillary transverse deficiency
Annals of Maxillofacial Surgery, 2020
Original Article-Retrospective Study IntRoductIon Maxillary deficiency and accompanying crossbite is a common malocclusion encountered clinically with a prevalence of 4%-23%. [1] Maxillary transverse deficiency (MTD) can be treated either orthodontically using rapid maxillary expansion (RME) or surgically using surgically assisted rapid palatal expansion (SARPE). In children and adolescents, conventional orthodontic RME has been successful when used prior to sutural closure. [2-6] In skeletally mature patients, the possibility of successful maxillary expansion decreases as sutures close and resistance to mechanical forces increases. [2,4,6] SARPE is an effective method of addressing the severe maxillary transverse discrepancy in patients over the age of 15 years. In young adults and adults in their 20s and 30s, palatal expansion may result in the tipping of the molars with little expansion of the maxillary arch. It has also been suggested that the intermaxillary suture anterior to the incisive canal never ossifies until very late in life, resulting in some relapse. [7-9] A number of modifications for the traditional SARPE surgical technique have been described. The traditional method describes a midpalatal osteotomy between the two central incisors, followed by maxillary expansion using a tooth-or bone-borne device. [5] Various combinations of maxillary, pterygopalatine lateral nasal, septal, and palatine osteotomies have been used based

T he facial growth of Class III malocclusion worsens with age, in this case, the early orthopedic treatment, providing facial balance, modifying the maxillofacial growth and development. A 7.6-year old boy presented with Class III malocclusion associated with anterior crossbite; the mandible was shifted to the right and the maxilla had a transversal deficiency. Rapid maxillary expansion followed by facemask therapy was performed, to correct the anteroposterior relationship and improve the facial profile. The patient was followed for a 15-year period, after completion of the treatment, and stability was observed. Growing patients should be monitored following their treatment, so as to prevent malocclusion relapse.

Our purpose in this case report is to present an orthodontic treatment obtained and the results achieved in 17-year-old white female patient with Angle Class II malocclusion and bilateral posterior crossbite. Patient was treated with bonded acrylic Hyrax appliance and surgically assisted rapid maxillary expansion (SARME). The multiloop system 0.16 TMA (ß titanium) arch wire was used in the alignment phase and on purpose to prohibit bite opening and optimize threedimensional movement control. After treatment bonded lingual retainers were placed in between maxillary central incisors and in mandible canine-to-canine. A functional removable Klammt appliance was used for retention. The 3D Laser Scanner Roland LPX-250 was used in order to obtain digital dental casts. Evaluation of the treatment results was measured on these models and using finite element scaling analysis (FESA). An Angle Class I relationship was obtained after 2½ years of treatment, function and facial aesthetics were improved. The shape of the palate changed significant in the width direction, not significantly in length and high direction. The greatest expansion of palate was found in the region between the palatal cusps of the first molars 26.6%, followed by first 21.9% and second premolars 16.5%. SARME in adult patients with bilateral cross bite and maxillary deficiency lead to satisfactory results. The 3D laser scanned models and their measurements, using advanced software's are successfully used for precise studies.

Severe class III malocclusion can be a great challenge, especially in adult patients. This case report describes an adult patient with severe skeletal class III malocclusion and with an obvious maxillary deficiency and mandibular excess causing both anterior and posterior crossbites in addition to a shift in the upper and lower midlines to the left concerning the facial midline. This was complicated by compensatory mechanisms such as the proclination of upper incisors and retroclination of lower incisors. Decompensation of the upper and lower arches was performed combined with upper arch expansion to relieve crowding in the upper arch and correct the posterior crossbite. This was followed by double jaw surgeries, including Le Fort I osteotomy in the maxilla and bilateral sagittal split osteotomy (BSSO) in the mandible. Orthodontic finishing procedures were then used to correct any other dental discrepancies. Remarkable esthetic and functional results were achieved with high patient ...

Aim: To evaluate the prevalence of anterior crossbite and to verify the effectiveness of the orthodontic appliance Inclined Plane in the correction of this malocclusion. Methods: The clinical examination was performed 702 children in the deciduous or mixed dentition of 7 schools and in those found the anterior crossbite was performed treatment with fixed Inclined Plane. Results: The prevalence of the anterior crossbite was 2.14%, characterizing 15 of the 702 children evaluated, of which 60% were female and 40% male, all of which were dental crossbites. Only 12 accepted the treatment with an average duration of 4.4 weeks. Conclusion: The prevalence of anterior crossbite was 2.14%. The inclined plane proved to be a viable and effective therapy in the correction of anterior crossbite. It is one of the options of the orthodontic treatment in patients in the deciduous or mixed dentition, propitiating greater possibility of dentoskeletal development, since the malocclusion is corrected.

R. V, a 16-year-old boy, presented with Class III end-on molar relationship on Class III skeletal base with below average mandibular plane angle and normal maxillomandibular differential. The upper canines were erupting, and late mixed dentition development was evident. Minimal spaces were present in both the arches. Normal transverse dimension of the dental arches was evident, but with some asymmetry in the mandibular arch. Left buccal segment was in lingual crossbite relationship, and the maxillary anterior teeth were characteristically locked in crossbite position with mandibular anterior teeth (3-prong crossbite). Treatment involved establishment of adequate curve of Wilson in the mandibular arch and mesialization of the maxillary buccal segment teeth using orthodontic miniscrews.
Maxillary Skeletal Expansion with the Assistance of Ortho Implants: A Clinical Case Report
Medical and Clinical Case Reports, 2021
Introduction: The maxillary skeletal expander (MSE) with the assistance of ortho implants is used to perform rapid palatal expansion in patients who are no longer growing. This case report describes a 15-year-old boy with a bilateral posterior crossbite caused by transverse maxillary deficiency. Methods: A 10-mm MSE was placed with four ortho implants. The MSE was activated once per day for 20 days. Subsequently, a fixed appliance (MBT) was placed as corrective treatment. Results: An approximate expansion of 8 mm was achieved using the MSE. The posterior crossbite was corrected by increasing the transverse dimensions of the maxilla. An adequate inter-arch relationship similar to the class I molar and canine relationships was achieved, as were a 2-mm overjet and 2-mm overbite. Conclusions: The use of the MSE with the assistance of ortho implants is an alternative method of treatment that can be beneficial for patients who are no longer growing. This method avoids the use of surgical ...
Compensatory orthodontic treatment for maxillary deficiency: a 4-year follow-up

In this article, we report the orthodontic treatment of a boy (age 12 years 9 months) who had a midface deficiency, a concave facial profile with maxillary retrusion, a complete crossbite (anterior and posterior), and the maxillary right canine retained in the alveolus. Rapid maxillary expansion was performed followed by complete orthodontic treatment with fixed appliances combined with Class III elastics and anterior vertical elastics. Time was allowed to elapse until growth was virtually over before removing the fixed appliances (at age 18 years 4 months), and no retainer of any type was used. As a result of treatment, significant improvement was noted in his facial appearance, with a proper maxillomandibular relationship, total correction of the maxillary atresia, and satisfactory overjet and overbite. The results remained stable at the 4-year follow-up. Therefore, it can be argued that the use of Class III elastics combined with rapid maxillary expansion has a beneficial effect ...
