TREATMENT WITH SPEED www.speedsystem.com Case Type: Class II Div II - Extraction of Upper First Bicuspids Problem List: Class II occlusion Transverse discrepancy Arch Length discrepancy Torque problems Over eruption of upper and lower incisors Case Resumé: A young lady age 14y 7m; more than 3 years post-puberty with a retrognathic mandible. Her parents declined surgery so the Cl II problem must be resolved via 2 pre-molar extraction. Extractions were not performed in the mandibular arch so as not to further compromise the profile and lip support. On the ceph tracing one can see the severity of the linguo-version of the upper incisors and the retrognathic mandible. She is a little brachycephalic. Treatment Plan Maxillary arch: X-tooth 14, 24 Alignment with .018 Supercable and .016 Super Elastic Nickel Titanium. Upper Canine retraction with .018 Stainless Steel, Upper Arch space closure and Torque control with .021 x .025 posteriorly reduced and finish with .018 x .025 Stainless Steel. Mandibular arch: Alignment with .014 Super Elastic Nickel Titanium, .018 Super Elastic Nickel Titanium and level arch .016 x .022 Stainless Steel and .018 x .025 Stainless Steel. Anchorage and Torque control (Transversely and Anteriorly) with .021 x .025 Stainless Steel. Treatment with the SPEED System™ - Class II Div. II Comments from Dr. Bérubé I have used the SPEED appliance since the start of my practice in 1986 because it offers many benefits. My patients appreciate SPEED’s miniaturized size and appearance. They find the mini-wingless attachments comfortable to wear and easy to clean. My staff find the appliance easy to work with and appreciate not having to change ligatures at each appointment. SPEED permits me to efficiently achieve my treatment objectives through the application of comfortably light forces applied in a very precise manner. My choice for slot size is the .022 slot as it gives me more versatility in choosing archwires. My prescription choice is the Hanson Prescription, developed by SPEED inventor Dr. G. H. Hanson. My bracket placement, especially in the lower arch, reflects this prescription choice. I have successfully treated thousands of patients with SPEED over the past 22 years of practice and I have been very satisfied with what it has enabled me to achieve. This case is typical of those seen everyday in my practice and was not chosen as a “miracle case”. It illustrates SPEED’s ability to correct severe crowding and impart incisor torque control during space closure. It is my feeling that SPEED is a very capable appliance, able to handle sliding mechanics and to control the transverse without tooth tipping. 21
