The aim of this article is to describe a case report of Class III malocclusion treatment with lower first molar extraction. The 27-year-old Caucasian male patient presented a symmetric face with a straight profile, hyperdivergent growth pattern, molar and cuspid Class III relation, and an anterior crossbite as well as a mild crowding on cuspids area, in both upper and lower arches and a tendency to posterior crossbite. The treatment was performed by the use of Haas expansion appliance followed by an initial alignment and leveling of the upper and lower arches with a fixed edgewise appliance, extraction of lower teeth aiming the correction of the incisors proclination and end the treatment with a Class I molar relationship. It resulted in a significant change in the patient’s profile, dentoalveolar Class III correction, upper arch expansion, leveling and alignment of the upper and lower arches, and improvement of tipping of the upper and lowers incisors. In cases of a dentoalveolar compensation in well positioned bone bases the treatment with fixed appliances is an alternative and extraction of lower teeth is considered.

The transpalatal arch might be one of the most common intraoral auxiliary fixed appliances used in orthodontics in order to provide dental anchorage. The aim of the present case report is to describe a case in which an adult patient with a tendency to class III, palatal compression, and bilateral posterior crossbite was treated with double transpalatal bars in order to control the torque of both the first and the second molars. Double transpalatal arches on both first and second maxillary molars are a successful appliance in order to control the posterior sectors and improve the torsion of the molars. They allow the professional to gain overbite instead of losing it as may happen with other techniques and avoid enlarging of Wilson curve, obtaining a more stable occlusion without the need for extra help from bone anchorage.

When treating young patients with Class III malocclusion, factors such as timing and an accurate prediction of growth of the mandible are very important. Even though early interceptive treatment of Class III might often be successful, clinicians should be careful to not initiate early treatment with premolar extractions which will compromise the success of orthognathic surgery later due to mandibular prognathism. This case report presents an adolescent female patient who developed a severe Class III skeletal discrepancy during growth and was treated with surgery after her growth had finished.

Abstract Background Class III malocclusion is associated with high sexual dimorphism, especially in individuals older than 13 years of age, with significant differences in growth between males and females during the pubertal and postpubertal stages, and in adulthood. The aim of this research was to examine differences between males and females in long-term stability (10 years) of treatment for skeletal Class III malocclusion. Methods Thirty patients (15 males and 15 females) with skeletal Class III malocclusion, who had been treated with rapid maxillary expansion (RME) combined with face mask protraction followed by fixed appliances, were selected sequentially. Thirty patients (15 males and 15 females) with skeletal Class I and mesofacial patterns treated only with fixed appliances for dental problems served as the control group. Differences between groups and sexes were evaluated using lateral cephalograms taken at the start of treatment (T0), immediately after the end of treatment (T1), and after 10 years (T2). The long-term treatment success rate was calculated. Results Ten years after Class III treatment, overjet and overbite relapse occurred similarly in females (− 0.68 ± 0.7 mm; − 0.38 ± 0.75 mm, respectively) and males (− 1.09 ± 1.47 mm; − 0.64 ± 0.9 mm, respectively); the ANB angle and Wits appraisal became significantly more negative in males (− 1.37 ± 1.06°; − 2.7 ± 2.53 mm) than in females (− 0.18 ± 1.26°; − 0.46 ± 1.94 mm). The success rate was 73.3% in males and 80% in females. Conclusions Significant differences in the long-term stability of Class III treatment outcomes have been found between males and females, with a larger skeletal Class III relapse and lower long-term success rates in males.

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.

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.

We describe the treatment of an adolescent girl, age 13 years old, with Class III malocclusion withnmultiple unerupted teeth in both jaw & retained deciduous teeth. Treatment consists mainly of correction of anterior crossbite, extraction of deciduous teeth, surgical exposure of unerupted teeth &orthodontic traction to help eruption, leveling and alignment with Edgewise fixed appliances with multiloop technique. Treatment time required 3years. However the treatment resulted in Class I molar occlusion with proper alignment of  upper & lower anterior segment, an ideal overjet, overbite andincisor angulations.Ban J Orthod & Dentofac Orthop, April 2013; Vol-3, No.2

The management of Class III malocclusion involves several considerations to be taken at the time of making therapeutic decisions, such as age, sex, the technique used, general conditions of the patient, collaboration and aesthetic requirements. This is a malocclusion that demands quick and effective action to ensure aesthetic and functional conditions as a priority. This report presents a case of a 14 years with a skeletal Class III malocclusion treated initially with facial mask and Mc .Namara breaker, in order to make a posteroanterior protraction of the maxilla and the mandible sagital control, then continue with the technique of MEAW multi-ansas, thus achieves a dentoalveolar compensation and better occlusal adjustment.

Class I malocclusion also called neutro-occlusion, this describes a normal molar relationship but there is malposition of one or more individual teeth. Treatment of Class I malocclusion varies depending on the condition and severity. However, the purpose of this report is to review the orthodontic treatment of a Class I malocclusion with buccally placed canine without extraction. This case report describes a 13-year-old girl with a Class I malocclusion, anterior and posterior crossbite, a retrusive maxilla with high canine. The Class I malocclusion with posterior crossbite was corrected with quad helix followed by non extraction orthodontic treatment with fixed appliances to correct anterior crossbite. At the end of treatment we obtained an acceptable occlusion relationship and the facial profile and the patient's smile were improved substantially.Ban J Orthod & Dentofac Orthop, April 2014; Vol-4 (1-2), P.20-22
