It is quite possible to treat cases with 5.5 mm crowding easily and predictably in less than 16 weeks. 4. Cases should have fully erupted posterior teeth to facilitate reten- tive clasps, with a reasonably well- aligned arch form to facilitate the path of insertion of the appliance. 5. Cases should be stable and prefer- ably free from periodontal disease. 6. Patients must agree to wear the Aligner for about 20 hours a day and be responsible for good appli- ance and oral hygiene. Should the patient wear the Aligner for 14 hours a day only, treatment will still be successful. Model evaluation/arch analysis with Spacewize Arch analysis should be performed before any Aligner case is attempted in order to ensure that the case is suit- able and, if not, what additional space creation techniques will be needed to allow the Inman Aligner to work. The extent of crowding present is calculated3 by measuring the sum of the mesial-distal widths of the teeth to be moved. This distance is called the required space or the teeth. If canines and incisors are to be moved, this dis- tance will be measured from the distal surface of one canine to the distal sur- face of the other canine. Using an orthodontic retaining or jeweller’s chain or a polishing strip, the ideal arch form is then measured from the distal of each canine in align- ment with the ideal arch form fol- lowing orthodontic correction. Criti- cally, the arch needs to pass through the suggested position of the contact points and not the incisal edges. This is described as the available space or the curve. It is possible to perform this task more quickly and just as accurately with software such as Spacewize. Just one simple occlusal photograph is required, which can be taken chair- side. One tooth needs to be measured for calibration. A curve can be digitally established and this is normally easier when observing the patient’s aesthetic requirements and occlusion directly. The extent of crowding is immediately calculated using such software. Laboratory requirements Accurate upper and lower impres- sions are taken, preferably two of the arch being treated. Simple alginate can be used if cast quickly. A bite registration and prescription should be completed and sent to a certi- fied Inman Aligner Laboratory. The technician should be informed of the amount of crowding calculated. The teeth to be repositioned should be noted clearly. The prescription should provide full details to the technician regarding the teeth to be moved, the area they are to be moved to and the distance they are to be moved. A Spacewize trace of the ideal curve can also be submitted. Interproximal reduction Interproximal reduction (IPR) is begun at the fitting appointment using abrasive strips or discs. The model analysis will have already calculated the extent of IPR required. Many authors acknowledge that the reduction of half of the inter- proximal enamel on the mesial and distal of each incisor tooth is a safe technique.4–7 This equates to 0.5 mm per contact point, creating 2.5 mm of space between the canines. In some cases, the distal of the canine and mesial of the premolar can be reproxi- mated allowing for a total of 3.5 to 4.5 mm. These cases will require more experience in using the system but offer a number of possibilities for cli- nicians once trained to use the system correctly. Meticulous records of the amount of stripping performed should be News COSMETIC TRIBUNE | September 20102C g CT page 4C AACD credentialing program opens to all dentists, dental laboratory technicians The American Academy of Cos- metic Dentistry (AACD) offers cos- metic dentistry’s most recognized advanced credentialing program for dentists and dental laboratory tech- nicians. In August, the American Board of Cosmetic Dentistry, the credentialing authority of the AACD, announced that all dentists and den- tal laboratory technicians are now eligible to pursue AACD Accredita- tion regardless of their membership status within the AACD. This visionary and historic change underscores AACD’s dedication to inclusiveness and standards of excellence, thus providing patients greater access to Accredited dental professionals who have demonstrat- ed a very high level of clinical skill and ability in cosmetic dentistry. The AACD is the world’s largest non-profit membership organiza- tion focused on providing cosmetic dental information, knowledge and credentialing for the dental profes- sion and the public. “Everyone wins when standards are held high and support and train- ing is made available to many,” said AACD Accredited Fellow Member and ABCD Board Member Bradley J. Olson, DDS. “The Accreditation pro- cess is an opportunity for dentists and dental laboratory technicians to truly gauge their skill set and expand their skills to a higher level.” Accreditation in the AACD serves to set standards for excellence in cosmetic dentistry. Accreditation is a three-part process, consisting of a written examination, submission of clinical case examinations for eval- uation, and an oral examination. Requirements for accreditation candidates will be identical for members and non-members. Non- members will be required to follow the AACD advertising guidelines, and will be subject to a different fee structure than AACD members. The AACD is the world’s largest non-profit membership organiza- tion dedicated to advancing excel- lence in comprehensive oral care that combines art and science to optimally improve dental health, esthetics, and function. Composed of more than 6,000 cosmetic dental professionals in 70 countries around the globe, the AACD fulfills its mis- sion by offering superior educa- tional opportunities, promoting and supporting a respected accreditation credential, serving as a user-friendly and inviting forum for the creative exchange of knowledge and ideas, and providing accurate and useful information to the public and the profession.
