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.

OBJECTIVE: This study aimed to evaluate the stability of molar relationship after non-extraction treatment of Class II malocclusion. METHODS: The sample comprised 39 subjects (16 females, 23 males) with initial Class II malocclusion treated with no extractions, using fixed appliances. Mean age at the beginning of treatment was 12.94 years, at the end of treatment was 15.14 years and at post-retention stage was 21.18 years. Mean treatment time was 2.19 years and mean time of post-treatment evaluation was 6.12 years. To verify the influence of the severity of initial Class II molar relationship in stability of molar relationship, the sample was divided into two groups, one presenting a ½-cusp or ¾-cusp Class II molar relationship, and the other with full-cusp Class II molar relationship. In dental casts from initial, final and postretention stages, molar, first and second premolars and canine relationships were measured. Data obtained were analyzed by dependent ANOVA, Tukey and Pearson's correlation tests, as well as independent t test between the two groups divided by severity of initial molar relationship. RESULTS: There was a non-statistically significant 0.12 mm relapse of molar relationship. The initial severity of Class II molar relationship was not correlated to relapse in the post-retention period. When compared, the two groups showed no difference in relapse of molar relationship. CONCLUSION: It was concluded that correction of Class II molar relationship is stable and initial severity does not influence relapse of molar relationship.

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.

Aim of the studyː to find if apical root resorption is related to orthodontic treatment time, type of appliance used and which are the most susceptible teeth to develop this type of resorption. Material and methodsː 70 patients (27 males and 43 females) selected from patients reffered for an orthodontic treatment at the Orthodontic Department of Faculty of Dentistry, University of Medicine and Pharmacy from TirguMures. The mean age at the beginning of treatment was 15.11 years for males and 14.67 years for females subjects. At the end of treatment, on their panormaic radiographs it was measured apical root resorption on incisors, premolars and molars in the upper and lower arch. Resultsː Root resorption was significantly (p< 0.05) correlated with fixed appliance treatment (49 percent). Patients with the longest treatment periods presented with significantly (p<0.05) more grade 2 resorptionː 28 months (± 2.6 SD) in the upper arch and 30 months (± 3.2 SD) in the lower arch. In the patients with the lowest treatment period (16 months in the maxilla and 18 months in the mandible arch) it was found no resorption. In the upper arch most of the patients (22.22 % males and 18.6% females) showed a grade 2 resorption in the incisor area. Root resorption of the premolars was seen in 18.5% of the male patients (7.4% with grade 2 ) and in 16.26 % of the female patients (6.97 with grade 2). Conclusionsː There is a high correlation between the orthodontic treatment time and apical root resorption. Most exposed to this process are incisors from bot, upper and lower arch. Less resorption was noticed in the premolar area.

One of the goals of functional-appliance devices is to modify the vertical growth pattern, solving several kinds of malocclusion. This study aimed to evaluate Class II malocclusion treatment’s stability with Austro Repositioner, followed by fixed appliances, and assess its capacity to modify vertical dimensions in brachyfacial patients. A test group of 30 patients (16 boys and 14 girls, mean 11.9 years old) with Class II malocclusion due to mandibular retrognathism and brachyfacial pattern treated with Austro Repositioner and fixed appliance were compared to a matched untreated Class II control group of 30 patients (17 boys and 13 girls, mean age 11.7 years old). Lateral cephalograms were taken at T1 (initial records), T2 (end of treatment), and T3 (one year after treatment). Statistical comparisons were performed with a paired-sample t-test and two-sample t-tests. Significant improvements in the skeletal Class II relationship were observed in the treated group. The ANB angle decreased (4.75°), the SNB angle increased (3.92°), and the total mandibular length (Co-Pg) increased (8.18 mm) (p < 0.001). Vertical dimensions were also significantly modified, the FMA angle increased (3.94°), LAFH-distance increased (3.15 mm), and overbite decreased (3.35 mm). These changes remained stable one year after treatment. The Austro Repositioner was adequate for treating the skeletal Class II malocclusion resulting from the mandible retrusion in brachyfacial patients.

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.

The records of 200 orthodontic patients accepted for treatment by the Orthodontic Department of the Bristol Dental Hospital in 1977 were compared with 200 taken on in 1985 in order to determine whether there had been any change in the proportion of referred cases requiring more complex procedures. Within each sample, cases were categorized as follows: (a) suitable for removable appliance treatment by an undergraduate or general practitioner; (b) requiring simple one arch fixed appliance treatment such as might he attempted by a general practitioner after a period of further training; (c) needing specialist treatment such as full multibracketed fixed appliances or orthognathic surgery. It was found that there had been no change in the proportions of simple and complex cases referred during the 8-year period although the proportion of patients now receiving complex treatment had increased greatly. Possible explanations and implications are discussed.

Gummy Smile

Vertical maxillary excess is associated with gummy smile, incompetent lip,  bimaxillary proclination, Angle’s class-I or class-II malocclusion with or without retogenia. After proper evaluation preoperative orthodontic treatment was performed in every cases and superior repositioning of the maxilla by Le Fort-I osteotomy is presented. Three patients with maxillary excess associated with retrogenia or microgenia were treated with this technique in combination with genioplasty. The maxillary segment was repositioned a maximum of 7.0 mm superiorly at point A. The mandible autorotated anterosuperiorly to achieve sound occlusion. Point B moved 1.0–3.0 mm anteriorly and 5.0–8.0 mm superiorly. The pogonion moved 4.0 mm anteriorly in a case done without genioplasty and the pogonion moved maximum 8.0mm in case done in combination with genioplasty. All patients obtained sound occlusion and a good profile after the operation. Almost no skeletal relapse was observed during 3 years of postoperative follow-up. Amount of gingiva showing during smile was ranges from 5.0mm –7.0mm which was 0-2.0mm after superior repositioning of the maxilla. Ban J Orthod & Dentofac Orthop, April 2016; Vol-6 (1-2), P.1-5

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.

Introduction. Orthodontic treatment of Class II Division 1 (II/1) malocclusions in adults can be challenging since skeletal effects are limited. Possible treatment options are orthodontic camouflage or orthognatic surgery, in severe cases. The aim of this paper was to present a successful management of Class II malocclusion in an adult patient using temporary anchorage devices (TADs). Case report. After detailed clinical examination, study models and cephalometric analysis, a 26 years old patient was diagnosed with Class II malocclusion, an overjet of 12 mm, congenitally missing tooth 41 and midline shifted to the right in upper dental arch. In prior orthodontic treatment, patient had upper premolars extracted. Posterior teeth in upper left quadrant were shifted mesially. The camouflage treatment was considered, using temporary anchorage devices (TADs) to distalize posterior teeth on the left side, and gain space for incisor retraction and midline correction in upper dental arch. Results. Using TADs as additional anchorage in anterior region and coil spring for molar distalization, the space was made for tooth 23, midline correction and incisor retraction. After 40 months, a satisfactory result was achieved, overjet and midline correction, class I canines occlusion and class II molar occlusion. Conclusion. Class II/1 malocclusion in adults can be successfully treated using TADs. The success depends on the severity of malocclusion and patient cooperation.
