Class II skeletal relation present with mandibular retrusion as a common etiological problem. Myofunctional appliances remain the main treatment methodology for growing patients with such problems. But when the patient reports at the penultimate end of growth curve or is non compliant, fixed functional appliances for mandibular advancement become the treatment method of choice. The present case is of a 14 year male with the chief compliant of irregular and forwardly placed teeth. On examination a skeletal and dental Class II relation with crowded anteriors was observed. Extraction of all 1 st premolars to relieve crowding along with 0.022 MBT prescription was used initially, followed by application of Powerscope Appliance for mandibular advancement. Significant improvemrnt of facial profile was seen due to forward displacement of mandible with the Powerscope Appliance. Thus it can be concluded that Powerscope Appliance is a useful novel innovation in the field of fixed functional appliances which can be successfully used to treat Class II patients.

The maxillary permanent canine is second only to the third molar in frequency of impaction, with a prevalence of approximately 2 per cent of the population; the palatal canine impaction being 85% of the impacted canines. The orthodontist treating patients with palatally impacted canines usually strives to build a complex treatment plan, based on uncomplicated and biological orthodontic and surgical techniques. The aim of the present case report is to demonstrate the potential of the orthodontic treatment of impacted canine with fixed appliance and open surgical technique for stimulation of physiological eruption of palatally impacted canine. This is a case of 12 year old female patient with maxillary bilateral canine impaction, the right maxillary canine was impacted palatally and the left canine buccally respectively, being treated by surgical exposure and fixed orthodontic therapy.

Introduction: It has been a widely accepted fact that race specific norms, diagnosis and treatment planning is now a explicit need for achieving desired orthodontic treatment outcome. Aim: The present study compares the cephalometric norms of Tweeds diagnostic triangle of the Assamese population with other Indian population s to justify this very fact. Materials and Methods: Tweeds cephalometric study was done on the cephalograms of Assamese ethnic origin and the norm for the population was derived. These cephalometric norms for the Assamese population was compared with the established Tweeds cephalometric norms of other Indian population. Conclusion:The statistically significant differences observed in the values of the parameters, are justify the legitimacy of the aforementioned hypothesis.

Various methods have been adopted to reduce orthodontic treatment time. These include biological approaches using vitamin D and prostaglandins; relaxin cytokines that include lymphocytes and monocytes-derived factors, receptor activator of nuclear factor kappa B ligand (RANKL), etc.; surgical methods such as corticotomy, piezocision, interseptal alveolar surgery, osteotomy, etc.; and noninvasive device-assisted methods such as mechanical vibration, photobiomodulation, etc. The biological and surgical approaches although more predictable have their own limitations of acceptance by patients. The present study, therefore, is a narrative review literature on the noninvasive methods to accelerate orthodontic tooth movement. A review of 56 articles related to the studies, using noninvasive methods, was done from 1987 to 2019. Photobiomodulation is one of the most studied noninvasive methods and has shown success in reducing the treatment time. More research is needed to make these methods more accessible and patient friendly.
