Class II malocclusion, the distal relationship between mandibular and maxillary molars, is very frequent in the population. In growing patients it carries a great risk of dental trauma, a more negative perception of facial and dental aesthetics a negative impact on the quality of life and self-esteem, a greater predisposition to periodontal diseases and a greater incidence of sleep disorders. It has different etiologies. Thus many treatment approaches can be used to correct this condition, either an orthopedic treatment and orthodontic treatment or a combination protocol. Functional devises have been widely used for the correction of the sagittal intermaxillary relationship in growing patients, but especially in the treatment of Class II. The success of a two phase treatment depends on its initiation during the growth period and on the patient’s degree of implication. This case illustrates a two phase treatment where sagittal correction was undertaken before transverse correction to make optimal use of the patient's pubertal growth spurt in first phase followed by a second phase of fixed appliance therapy during adolescence to achieve optimal results.

A case is described in which a Class II malocclusion with severe Class II skeletal pattern was treated with a modified Twin Block Appliance. The patient, an II-year-old girl, had initially presented with an ameloblastoma located in the right maxilla. The subsequent defect produced by surgery was obturated by the appliance during her orthodontic treatment, which was undertaken during her pubertal growth spurt Two years later the result was stable, allowing the provision of a more definitive prothesis to restore the occlusion.

Orthodontic treatment of Class II, division 1 malocclusion in one or two phases is still controversial in contemporary Orthodontics. The present clinical case presents the orthodontic treatment of a 6-year-old patient with aesthetic complaint regarding the smile and bullying, presenting skeletal Class II, Class II malocclusion, Angle division 1, overjet with exaggerated protrusion of the maxillary incisors, exaggerated overbite with the lower incisors touching the palatal mucosa, absence of lip sealing and concave inferior face profile. In Phase I, rapid maxillary expansion was performed with Hyrax-type expander together with the Herbst fixed functional orthopedic device for 11 months. In Phase II, the fixed orthodontic appliance associated with intermaxillary elastics was used for 13 months. The two-phase treatment of Class II malocclusion, division 1 showed to be effective after 24 months, establishing adequate occlusal and functional results and improving the aesthetics of the lower third of the face.

OBJECTIVE: The aim of this study was to cephalometrically assess the skeletal and dentoalveolar effects of Class II malocclusion treatment performed with the Jones Jig appliance followed by fixed appliances. METHODS: The sample comprised 25 patients with Class II malocclusion treated with the Jones Jig appliance followed by fixed appliances, at a mean initial age of 12.90 years old. The mean time of the entire orthodontic treatment was 3.89 years. The distalization phase lasted for 0.85 years, after which the fixed appliance was used for 3.04 years. Cephalograms were used at initial (T1), post-distalization (T2) and final phases of treatment (T3). For intragroup comparison of the three phases evaluated, dependent ANOVA and Tukey tests were used. RESULTS: Jones Jig appliance did not interfere in the maxillary and mandibular component and did not change maxillomandibular relationship. Jones Jig appliance promoted distalization of first molars with anchorage loss, mesialization and significant extrusion of first and second premolars, as well as a significant increase in anterior face height at the end of treatment. The majority of adverse effects that occur during intraoral distalization are subsequently corrected during corrective mechanics. Buccal inclination and protrusion of mandibular incisors were identified. By the end of treatment, correction of overjet and overbite was observed. CONCLUSIONS: Jones Jig appliance promoted distalization of first molars with anchorage loss represented by significant mesial movement and extrusion of first and second premolars, in addition to a significant increase in anterior face height.

The current concept for effective and efficient treatment of skeletal Class II malocclusion prescribes that interceptive approach should be delivered during the pubertal growth stage. However, psychosocial issues and a greater risk of dental trauma are also factors that should be addressed when considering early Class II therapy. This paper reports a case of a patient that sought orthodontic treatment due to aesthetic discomfort with the incisors’ protrusion. Two previous treatments failed because patient’s collaboration with removable appliances was inadequate. Given his history of no collaboration and because the patient was in the prepubertal stage, it was decided to try a different approach in the third attempt of treatment. Traumatic injury protective devices were used during the prepubertal stage and followed by Herbst appliance and fixed multibrackets therapy during the pubertal stage, resulting in an adequate outcome and long-term stability.

Distal Occlusion

ABSTRACT A distal occlusion exerts restraining occlusal forces on the mandibular dentition, and the maxillary dental arch is narrow from distal positioning of the lower dentition. These factors may not allow the mandible to grow to its full genetic potential In severe class II. In the hands of an experienced clinician, full time functional appliances are most efficient in correcting severe class II malocclusion than conventional fixed appliance techniques without mandibular propulsion. This is especially true when the treatment is timed to coincide with the pubertal growth spurt. A case successfully treated with two phase treatment to meet the functional treatment objective is presented.

This paper is mainly intended for postgraduate orthodontic students especially for those who will learn and practice the Fixed Appliance Technique. With the advancement of research, introduction of new biomaterials and techniques, the orthodontic treatment has been scientifically affordable for the last few decades. In Bangladesh the orthodontic treatment and education is also becoming very popular in the private and institutional level day by day. In fact, post-graduate trainee doctors in the department of orthodontics & Dentofacial Orthopedics, Dhaka Dental College and Hospital were the once who had the idea of writing this paper. While supervising & conducting FCPS Part II examination as a convener, I felt this sort of clinical and technical review would be very helpful for the trainees as well as practitioners. Keeping that thought in my mind, I also intend to write a series of papers that will contain the basic as well as contemporary orthodontic techniques and philosophy. Post-graduate trainee doctors, faculty members and private practitioners will all find this paper as a guideline during their training as well as in professional practicing period. I am very much delighted to present this paper and series of papers in the next subsequent issues. The present paper describes training techniques, the design of standard edge-wise-technique in sequential stages for treating Angle Class II maxillary protrusion with excessive over jet, overbite (upper and lower 1st premolar extraction case), and illustrated case reports1,2 of class II malocclusion. The author acknowledges that the paper is summarized from lectures, handouts during his postgraduate studies in Kyushu University and Hiroshima University, Japan and also clinical experience acheived from the Department of Orthodontics and Dentofacial Orthopedics, Dhaka dental College and Hospital and private practice in Bangladesh.

ABSTRACT Objective:  To compare the short-term skeletal and dental effects of two-phase orthodontic treatment including either a Twin-block or an XBow appliance. Materials and Methods:  This was a retrospective clinical trial of 50 consecutive Class II cases treated in a private practice with either a Twin-block (25) or XBow (25) appliance followed by full fixed orthodontic treatment. To factor out growth, an untreated Class II control group (25) was considered. Results:  A MANOVA of treatment/observation changes followed by univariate pairwise comparisons showed that the maxilla moved forward less in the treatment groups than in the control group. As for mandibular changes, the corpus length increase was larger in the Twin-block group by 3.9 mm. Dentally, mesial movement of mandibular molars was greater in both treatment groups. Although no distalization of maxillary molars was found in either treatment group, restriction of mesial movement of these teeth was seen in both treatment groups. Both treatment groups demonstrated increased mandibular incisor proclination with larger increases for the XBow group by 3.3°. The Wits value was decreased by 1.6 mm more in the Twin-block group. No sex-related differences were observed. Conclusions:  Class II correction using an XBow or Twin-block followed by fixed appliances occurs through a relatively similar combination of dental and skeletal effects. An increase in mandibular incisor inclination for the XBow group and an increased corpus length for the Twin-block group were notable exceptions. No overall treatment length differences were seen.
