Class Iii Treatment

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.

Class Iii Treatment

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 prevalence of class III malocclusion ranged from 0 to 26% in different populations. Many types of treatments have been described in dental literature. The results of early treatment have been positive. The purpose of this report is to describe the case of a four-year-old patient with class III malocclusion who received an innovative treatment using direct anterior tracks. This therapy efficiently obtained immediate improvement of profile and occlusal relationships.

The purpose of this case report is to add another means of treatment for the anterior crossbite malocclusion in early mixed dentition. The selected functional device is an eruption guidance appliance (EGA). The analysed patient had a functional anterior crossbite, a mandibular protrusion tendency, and a normodivergent growth pattern. The early treatment was suggested to correct the malocclusion and avoid unfavourable occlusal conditions that could end in a class III malocclusion growth pattern. After 18 months of treatment, with night-time use, the malocclusion was completely resolved. This therapy strategy allowed the correction of the sagittal jaws’ relationship and maximum control of the vertical dimension. After 2 years of follow-up, the results were preserved. The peculiarity of this kind of intraoral orthodontic tools is the use of the erupting forces rather than the active forces. This early treatment of anterior crossbites with EGA may be considered an effective treatment approach for achieving good functional and aesthetic results.

INTRODUCTION: This case report describes the orthodontic treatment of an adult patient with skeletal Class III malocclusion and anterior crossbite. A short cranial base led to difficulties in establishing a cephalometric diagnosis. The patient's main complaint comprised esthetics of his smile and difficulties in mastication. METHODS: The patient did not have the maxillary first premolars and refused orthognathic surgery. Therefore, the treatment chosen was orthodontic camouflage and extraction of mandibular first premolars. For maxillary retraction, the vertical dimension was temporarily increased to avoid obstacles to orthodontic movement. RESULTS: At the end of the treatment, ideal overjet and overbite were achieved. CONCLUSION: Examination eight years after orthodontic treatment revealed adequate clinical stability. This case report was submitted to the Brazilian Board of Orthodontics and Facial Orthopedics (BBO) as part of the requirements to become a BBO diplomate.

Introduction: Class III malocclusion has skeletal and dental components that can often impair the patient's facial appearance. Its treatment may involve orthognathic surgery or compensatory orthodontics. Case report: This case report presents a Class III malocclusion compensatory orthodontic treatment performed with the Biofunctional prescription brackets. Biofunctional prescription presents a torque value of 0° for the maxillary incisors and +10° for the mandibular incisors, which counteracts to the side effects of the use of Class III intermaxillary elastics, minimizing it, providing a more stable, aesthetic and with a healthier periodontal occlusion. Conclusion: The Class III malocclusion compensatory orthodontic treatment performed with Biofunctional prescription obtains satisfactory results, even depending on the patient collaboration with the use of intermaxillary elastics.

INTRODUCTION: Angle's Class III malocclusion is a dental discrepancy in a sagittal view that may appear or not with an important skeletal discrepancy. Facial esthetics may be affected by this skeletal discrepancy and it is one of the most common complaints of patients who seek orthodontic treatment. Class III treatment, in adults, may be done by compensatory tooth movement, in simple cases, or through an association between orthodontics and orthognathic surgery, in more severe cases. OBJECTIVE: This article describes a non-extraction compensatory Class III treatment case, applying the Tweed-Merrifield mechanical principles with headgear (J-Hook) in the mandibular arch. This case was presented at the V Brazilian Association of Orthodontics and Dentofacial Orthopedics (ABOR) Meeting, it was evaluated by members of Brazilian Board of Orthodontics and obtained third place in the general classification.

This study aims at reporting the clinical case of a patient with Class III skeletal malocclusion with severe maxillary deficiency, producing a reduced midface associated with severe mandibular prognathism. The pre-surgical orthodontic preparation was composed mainly by dentoalveolar expansion and repositioning of the incisors in the lower arch. Then, a combined maxillary and mandibular orthognathic surgery was performed. The treatment objectives were achieved, with significant improvement in facial esthetics and occlusion, followed by post-treatment stability. This case was presented to the Brazilian Board of Orthodontics and Facial Orthopedics (BBO), as part of the requirements for obtaining the title of Diplomate by BBO.

Class III malocclusion is one of the most difficult problems to treat. It has a multifactorial etiology involving both genetic and environmental causes. The dental and skeletal effects of maxillary protraction with a facemask are well documented in several studies. Although incorporation of expansion appliance along with facemask therapy can improve correcting both sagittal and transverse discrepancy of maxilla. The following case shows early treatment of a 9 year old boy with maxillary deficiency using an expansion screw along with facemask. Facemask therapy was followed by fixed orthodontic treatment to settle the occlusion. Treatment was completed after 14 months with positive overjet, class I molar and canine relationship on right and left side.
