CATEGORY 46 AUSTRALASIAN DENTIST LINICAL the maximum amount of possible activation with respect to the tooth position and modulus of elasticity of the appliance material. Advantages of Aligner set-up Nelson (2006), described several advantages of the aligner software that were summarized as; u The set-up can be used for diagnosis and treatment planning, to evaluate the need for IPR, expansion, extraction, distalization and other movements, u Verifying that the technician has performed modifications, u A consultation device to show treatment limits to patient, u Verifying that the aligner is tracking, u Evaluating anchorage with the superimposition or surgical simulation tools and staging, u Addressing the patient’s chief concern (of anterior tooth alignment) at the beginning of the series, and applying simultaneous movements to reduce the overall number of aligners. Orthodontists can now couple the proposed tooth movements in their treatment plans to the virtual setup and verify that all tooth movements are accurate in all three planes of space. The orthodontist’s control of tooth movement not only increases the accuracy of the final positioning of the teeth, but it also saves considerable time by requiring fewer modifications. Summary – An overview: Diagnostic records with computer aided tomography (CAT) or a polyvinyl siloxane impression and photographs are taken. Along with the doctor’s instruction, it is submitted to the company. The Intra oral scan / impression create an accurate 3D digital model of dental arch. The teeth are then digitally sectioned, the dental arches are related to each other and the movements are staged. The preliminary plan is sent to the doctor for his approval and then the digital model is transferred to a cast and clear plastic aligner is formed over each cast. And finally the set of aligners is sent to the doctor. Conclusion To achieve good outcome, the priority is to establish our orthodontic treatment goal of achievement, and then contemplate the force system that move teeth to final position. The choice of the appliance depends chiefly upon the severity of the malocclusion, the proficiency of the clinician in influencing the treatment outcome, the ability of the orthodontist’s clinical judgement & the patient’s needs. Therefore, the choice of clear aligner treatment shouldbebasedonsoundclinical judgement & knowledge about the pros and cons of the appliance and the clinician should be able to make a sound assessment of the treatment systems available to them for potential clinical utility. u REFERENCES Chen, Y.J., et al.
