Analysis of sagittal jaw relationship is important in orthodontic diagnosis and treatment planning, and can be investigated by angular or linear parameters. In the present study an analysis was performed using profile cephalograms of 40 children with skeletal Class II malocclusion. A correlation analysis is presented, involving five different methods of expressing sagittal jaw relationships. Whilst some degree of agreement could be noted, it was not possible to suggest a pair of measurements, which in combination, could give a more accurate picture of sagittal jaw relationships.

Malocclusions in the vertical plane are more difficult to treat as compared to the malocclusions in the sagittal plane as they often require multidisciplinary (surgical) approach. Skeletal vertical deficiency and excess causes jaw discrepancies in the sagittal vector too due to rotation of the mandible, thus presenting a complex situation which requires astute treatment planning and implementation. In this article, two cases treated with combined orthodontics and orthognathic surgery to treat skeletal class II malocclusion with vertical deficiency and excess are shown and all details of treatment planning are discussed.

Treatment of class II malocclusion requires accurate diagnosis and treatment planning. This case report outlines the successful management of a growing skeletal class II using Forsus fatigue resistant device for correction of skeletal parameters and premolar extractions for correction of dental parameters. The patient’s profile improved significantly with a 4° reduction in ANB angle. An ideal overjet, overbite and molar relation were also attained.

Treatment Alternatives

Class II malocclusion has a high incidence in the population, which may compromise smile aesthetics, occlusion function and stability. Skeletal Class II may affect facial aesthetics and upper airway volume. Class II malocclusion is routinely associated with skeletal Class II condition, having as treatment alternatives the use of Extra Buccal Appliance (EBA) or removable or fixed propulsor appliance. This article describes a case of a patient who did not accept the use of EBA and so it was fitted a Flex Developer propulsor for Class II correction and discussed the advantages and disadvantages of therapeutic alternatives for Class II correction.

Adequate planning and early treatment of Angle Class II malocclusion with maxillary atresia and anterior open bite provides harmonization of maxillomandibular bone bases in the three planes of space. Orthodontic aligners have emerged as an alternative treatment having the following advantages: being more aesthetic and more comfortable for the patient, less treatment time when they are correctly indicated, less chairside time, less complications, possibility of remote monitoring, easier feeding, and dental hygiene. On the other hand, they offer difficulties to treat adults with severe skeletal Class II malocclusions, posterior crossbite and anterior open bite. Therefore, the objective of this clinical case report is to early correct skeletal Class II malocclusion with maxillary atresia through the use of mechanical orthopedics and devices that help eliminate habits and close the anterior open bite, and later the use of orthodontic aligners to finish the treatment. It was concluded that the early interceptive treatment of malocclusion was efficient to harmonize the bone bases in the anteroposterior, vertical, and transversal directions, changing this malocclusion from high to low complexity and, consequently, highly predictable and with an excellent prognosis for treatment with orthodontic aligners. The treatment with ClearCorrect aligners corrected the occlusion in a shorter period of time when compared to corrective orthodontics and with a high predictability in relation to the virtual setup.

The aim of this study was to evaluate the efficiency in using intermaxillary elastics to stimulate mandibular growth and advancement in orthodontic patients diagnosed with skeletal Class II malocclusion as well as to compare the use of these Class II elastics in two different therapeutic approaches. The sample consisted of 60 orthodontic patients aged 10-15 years, 34 girls and 26 boys. The sample was divided into two equal groups (each consisting of 30 patients). Patients belonging to the first group (Group 1) were subjected to 1/4�� - 6.0 oz elastics and were advised to change the elastic every 24 hours. Patients belonging to the second group (Group 2) were subjected to 1/4�- 4.5 oz elastics but with a recommendation to change the elastics every 12 hours. In order to evaluate the effectiveness of these two types of Class II elastics on mandibular growth and advancement, the value of the SNB angle at the beginning of the treatment (T1) was compared with the value of the SNB angle after 5 months of wearing intermaxillary elastics (T2). All patients showed statistically significant increased values of the SNB angle during the orthodontic treatment (p[0.001). Patients in Group 2 showed a significantly higher statistical increase (p[0.05) than patients in Group 1.

Common Problems

Skeletal Class II malocclusion with mandibular deficiency is one of the most common problems that patients seek treatment. Adult patients with severe skeletal Class II malocclusion need orthognathic surgery for successful treatment. Bilateral sagittal split osteotomy (BSSO) is the most often preferred technique for these patients. This case report briefs about two male patient of age 24 years presented with Class II Skeletal relation, mesoprosopic facial form, horizontal growth pattern and Angle’s Class II div 1 malocclusion who were treated with Bilateral sagittal split osteotomy (BSSO) mandibular advancement. The ideal anteroposterior relation was established along with a Class I molar, incisor, canine relationship and ideal overjet, overbite and the overall facial esthetics were significantly improved. Combined surgical-orthodontic treatment aims to obtain a more harmonious facial, skeletal, dental and soft tissue relationship with an added patient self esteem.
