The importance of correcting Angle's Class II molar relationships during orthodontic treatment is discussed and two methods of achieving this correction are described. The literature is reviewed and an investigation designed to compare the modes of action of extra-oral traction and functional appliances is described. The base line for cephalometric measurement is taken as S-N with a perpendicular axis constructed at S in order to minimize errors due to growth occurring during the investigation period. Results suggest that neither appliance has significant effects on the horizontal growth of the dental bases, but that the clinical effect of molar relationship correction is substantially due to dento-alveolar changes.

We are in the process of discovery of new vistas for technological advances in terms of various appliances with a vision of making orthodontic treatment compliance free as well as successful. Due to improved technology, the enigma of treating the Class II syndrome is palliated. “Out of the box” thinking has become a norm to treat certain situations that were not corrected in noncompliant patients. Fixed functional appliances are valuable tools introduced to assist the correction of skeletal Class II malocclusion with mandibular retrognathia at the deceleration stage of growth for achieving stable results. In this direction a case series is reported of patients having the above conditions and undergoing orthodontic treatment using a Forsus FFA. Joining hands with technology is a win-win situation for both the patient and the orthodontist.

Summary Background/objectives Whether orthodontic treatment with functional appliances improves facial aesthetics is still under debate. This study aimed to determine whether functional orthodontic treatment improves the facial attractiveness of patients with Class II division 1 malocclusion. Materials/method Extraoral lateral photographs of 20 children with Class I (CLI, 11.7 ± 0.8 years), and before (T1) and after treatment (T2) photographs of patients with Class II division 1 (CLII T1 and CLII T2; mean age ± SD = 11.1 ± 0.6 years) treated with functional appliances, were transformed into black silhouettes. Three panels of examiners including 30 orthodontists (39.0 ± 10.1 years), 30 dentists (40.0 ± 9.7) and 30 laypersons (39.0 ± 9.2) evaluated the attractiveness of patients’ silhouettes using a 100-mm visual analogue scale, and the sagittal position of patients’ upper lip, lower lip, and chin using a 3-point Likert scale. Two-way ANOVA and a chi-square test were used to test differences among groups. Statistically significance was set as P  <  0.05. Results The silhouettes of CLII T2 individuals were more attractive than those of the other groups (all Ps < 0.001). The upper lip, lower lip, and the chin of these individuals were judged to be normally positioned in 69.5 per cent, 74.9 per cent, and 72.3 per cent of the assessments, respectively (all Ps < 0.05). Limitations This study did not account for the psychological profile of the examiners, which may have affected the ratings. Conclusions/implications Orthodontic treatment with functional appliances is associated with a superior facial profile attractiveness. Functional treatment should be considered as a treatment option to improve the facial appearance of children with Class II division 1 malocclusion.

The aim of orthodontics treatment is normalization of teeth position in three planes, using various orthodontics appliance to reach the chepalometric standar and normal occlusion. Orthodontic treatment for dentoskeletal class II division 1 malocclusion in growing patients using myofunctional appliance may correct anteroposterior planes of mandibula. This study was a descriptive retrospective analytic study to look at the success of Orthodontic treatment for dentoskeletal class II division 1 in growing patients with myofunctional appliance using chepalometrics analysis Steiner value. The sample used in this study is chepalogram radiographic from patient with dentoskeletal class II division 1 malocclusion in growing patients before and after using myofunctional appliance in PPDGS orthodontics Clinic of Padjadjaran University. Statistic analysis were performed with pair t-test and Wilcoxon. Based on this study, it is concluded that orthodontic treatment with myofunctional appliance such as activator and twin block in growing patient with dentoskeletal class II division 1 malocclusion shows significant changes and compatibility with the normal criteria.

The Forsus appliance is one of the most commonly used rigid fixed functional appliances in the correction of class II malocclusion. It is often seen that parts go missing with regular usage of the appliance. Replacement of the same is expensive and also requires a large inventory. An innovative low-cost and easy option for lost or broken split crimps is described in this article.

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.

ABSTRACT Objective:  To assess the maxillary second molar (M2) and third molar (M3) inclination following orthodontic treatment of Class II subdivision malocclusion with unilateral maxillary first molar (M1) extraction. Materials and Methods:  Panoramic radiographs of 21 Class II subdivision adolescents (eight boys, 13 girls; mean age, 12.8 years; standard deviation, 1.7 years) before treatment, after treatment with extraction of one maxillary first molar and Begg appliances and after at least 1.8 years in retention were retrospectively collected from a private practice. M2 and M3 inclination angles (M2/ITP, M2/IOP, M3/ITP, M3/IOP), constructed by intertuberosity (ITP) and interorbital planes (IOP), were calculated for the extracted and nonextracted segments. Random effects regression analysis was performed to evaluate the effect on the molar angulation of extraction, time, and gender after adjusting for baseline measurements. Results:  Time and extraction status were significant predictors for M2 angulation. M2/ITP and M2/IOP decreased by 4.04 (95% confidence interval [CI]: −6.93, 1.16; P  =  .001) and 3.67 (95% CI: −6.76, −0.58; P  =  .020) in the extraction group compared to the nonextraction group after adjusting for time and gender. The adjusted analysis showed that extraction was the only predictor for M3 angulation that reached statistical significance. M3 mesial inclination increased by 7.38° (95% CI: −11.2, −3.54; P < .001) and 7.33° (95% CI: −11.48, −3.19; P  =  .001). Conclusions:  M2 and M3 uprighting significantly improved in the extraction side after orthodontic treatment with unilateral maxillary M1 extraction. There was a significant increase in mesial tipping of maxillary second molar crowns over time.
