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 satisfaction.

Leveling And Alignment

Class III malocclusions present a great challenge for many orthodontists, especially if malocclusions are found in adult patients and alongside other dental problems. This case report shows an adult patient with a skeletal class III anterior crossbite, a unilateral posterior crossbite on the right side, a congenital absence of both lateral incisors and retained deciduous teeth, and shift in the lower midline. The upper retained deciduous teeth and lower premolars were extracted. Leveling and alignment were initiated. Build-up composite resin placed on the first molars allowed for bite opening. The crossbites were corrected by using sequentially larger archwires combined with class III elastics until both the anterior and posterior crossbites were corrected. The impacted upper right canine was exposed using the closed eruption technique and leveled into the position of the upper lateral incisor. Miniscrews were utilized to close the residual spaces. Both canines were reshaped to simulate the upper lateral incisors. At the end of the treatment, good esthetic and functional results were obtained. In conclusion, orthodontic camouflage can be a viable option for treating patients with multiple skeletal and dental problems.

Class III malocclusions with a severe hyperdivergent growth pattern are very complex to plan and treat. This case report describes the treatment of an adult with a skeletal Class III malocclusion with a midface deficiency, severe bilateral posterior crossbite, and a severe hyperdivergent growth pattern by a combination of a bonded rapid maxillary expansion appliance and surgical procedure of Le Fort I osteotomy for maxillary advancement.

Angle Class Iii Malocclusion

Many studies report that maxillofacial growth is influenced by genetic and environmental elements and that incorrect breathing, chewing, sucking, and swallowing are promoting factors of malocclusion. This study aims to evaluate the function and the influence of the tongue positions in patients with Angle class III malocclusion, maxillary hypoplasia, and posterior crossbite. One hundred patients, aged between 6 and 12 years old, were enrolled for the study. In the first group, patients with a diagnosis of class III malocclusion, affected by maxillary hypoplasia, skeletal class III, and posterior dental crossbite were recruited. In the control group, not treated patients with no malocclusion, skeletal class I, and without posterior dental crossbite were selected. Regarding atypical deglutition, no statistical differences were reported between the two groups, and 14% of patients reported ankyloglossia. Statistical differences were found in tongue rest position and during the execution of “hold and pull” and “chuck” exercises. Results obtained in this observational study showed that the clinician (orthodontist or general dentist) should analyze the presence/absence of atypical swallowing, the anatomical and functional aspects, and the tongue behavior in the rest position.

The Alt-RAMEC protocol was introduced by Liou in the year 2005. It allows for sutural mobilisation by opening and closing the RME screw for 7-9 weeks. Maxillary protraction after the use of Alt-Ramec (alternate rapid maxillary expansion and contraction) protocol is an efficient method for early treatment of skeletal Class III malocclusion. This case report shows the results of using a hyrax bonded maxillary expander with the Alt-RAMEC protocol to treat a maxillary hypoplasia Class III malocclusion. A 12-year-old patient with skeletal class III malocclusion with anterior as well as the unilateral posterior crossbite was treated using this protocol. CBCT scans were taken before and after expansion. These CBCT scans were used for assessing and analysing the skeletal changes that have occurred after using the AltRamec protocol. The objective of this case report is to assess skeletal changes after using the Alt-RAMEC protocol.

ABSTRACT Treatment of hyperdivergent skeletal Class III malocclusion is challenging for orthodontists, and orthognathic-orthodontic treatment is usually required. This report presents the successful nonsurgical treatment of a 20-year-old man who had a skeletal Class III malocclusion with anterior open bite, anterior and posterior crossbite, hyperdivergent growth pattern, steep occlusal plane, early loss of three first molars, and an uncommon convex profile with a retruded chin. An orthodontic camouflage treatment plan was chosen based on the etiology and the patient's complaints. Tooth #37 was extracted. Miniscrews were used for uprighting and intruding of the lower molars, distalization of the lower dentition, and flattening of the occlusal plane. After 34 months of active treatment, Class I relationships, proper anterior overjet and overbite, flat occlusal plane, and an esthetic facial profile were achieved. The results demonstrated that the biomechanics involved in the nonsurgical treatment assisted with miniscrews to distalize the mandibular dentition and flatten the occlusal plane while keeping the mandibular plane stable was effective for treating this hyperdivergent skeletal Class III patient with a convex profile and anterior open bite.

Relevance. Skeletal Class III malocclusion is known to be one of the most difficult malocclusions to correct. Nonsurgical treatment of Class III in adults is a challenge; however, this patient refused surgery. A treatment method with Fixed Anterior Growth Guidance Appliance (FAGGA) was investigated in the study.Materials and methods. This case report presents a 37-year-old woman with skeletal Class III malocclusion for maxillary deficiency. As the patient didn’t agree to surgery, she was treated by Fixed Anterior Growth Guidance Appliance, followed by 3D SMILE® clear aligners. Fixed Anterior Growth Guidance Appliance was used initially. After 4 months, the appliance was removed and clear aligner treatment was initiated. Post-treatment radiographs showed improvement.Results. Intraorally, in the upper arch, a total of 4.00 mm of space were gained (about 2.00mm distal to each canine). The post-treatment cephalometric analysis showed a skeletal A-P Class I, the Upper incisor inclination to the optic plane was not significantly altered, ANS — antArc was improved by 1.5mm, the Effective Length of the Premaxilla increased by 2.6mm, U1 — ANS’ decreased by 1.7mm, Incisor mandibular plane angle (IMPA) autonomously improved by 11 degrees.Conclusions. Maxillary deficiency was corrected successfully with the Fixed Anterior Growth Guidance Appliance. The treatment is being continued by 3D SMILE® clear aligners. The goal was achieved despite the patient’s age and nonsurgical treatment.

ABSTRACT A 19-year-old female came to our department with the chief complaint of facial asymmetry. Clinical examination showed skeletal class III relationship with mandibular prognathism, large reverse overjet, lower right mild crowding, and left hemimandibular elongation. After a thorough discussion with the patient, she accepted the proposal of orthognathic surgery and mandibular setback by bilateral sagittal split osteotomy (BSSRO), and therefore, tooth extraction was performed for 18, 28, 38, and 48 before the surgery. An improved superelastic Ti-Ni alloy wire (ISW wire), developed by Tokyo Medical and Dental University, was then used to facilitate the correction of lower crowding. Involved mechanism included intermaxillary elastics for a better interdigitation and jaw relationships. Adequate overbite and overjet were achieved after treatment completion.
