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 1st 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.

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. Keywords: Cephalometric norms variation, Indian population, Tweed’s analysis.

It is commonly observed that multiple impacted permanent teeth are usually linked to syndromes, hormonal and metabolic disorders. Nevertheless some cases of impaction of multiple teeth are non syndromic. In the present case report, we confer about a 22-year-old female non syndromic patient with missing teeth. Radiological investigation from OPG revealed multiple impacted permanent teeth, though medical and family history along with physical examination was not suggestive of any syndromes. Keywords: Multiple impaction, Non syndromic patient

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. Keywords: Impacted canine, Orthodontically guided eruption.

The cephalometric norms of different ethnic and racial groups established in various studies show that normal measurements for one group are not necessarily normal for another group; each racial group must be treated according to its own characteristics. The materials used in this study consist of cephalometric radiographs of 50 subjects (23 males, 27 females) from Assamese ethnic background. The head films were traced on A4 size acetate matt paper using 3Hb pencil and Tweeds cephalometric analysis was done. Three angular parameters Frankfort mandibular plane angle (FMA), Frankfort Mandibular Incisal Angle (FMIA), Incisor mandibular plane angle (IMPA) for the Assamese population, were measured and found to be 25.4, 56.6 and 98.06 degree respectively. There was no clinical significant different between Assamese male and female but there is highly significant among the Assamese and Caucasian parametric values of Tweeds diagnostic triangle.
