Orthodontic Treatment Mechanics and the Pre-adjusted Appliance
Program Highlights
This course presents a general discussion on the philosophy of orthodontic treatment. This includes a brief discussion of the history of the pre-adjusted appliance system, information on direct and indirect bracket placement, and an efficient method of arch form management. The main emphasis of the course, however, is on inter-arch treatment mechanics. State-of-the-art mechanics using light continuous force systems are described in detail. The six stages of orthodontic treatment are reviewed using a variety of case reports. These stages include anchorage control, leveling and aligning, vertical dimension control, antero-posterior correction, space closure and finishing. The new Avex appliance systems will be discussed in some detail as well as information on exciting new adhesives and the arch wire system. This is a practical and a very clinically oriented program, which will provide information that is immediately useful for the modern orthodontic practice. Selected cases from the other six courses will also be presented intermittently throughout the program.
Program Format
- Bracket Placement: The three keys to bracket placement (the Andrews references, the bracket placement chart, and the marginal ridges) are discussed. Recommendations for direct and indirect bonding are presented, with discussion about the adhesives used during both direct and indirect bonding.
- Leveling and Aligning: The difference between extraction and non-extraction treatment during this stage is reviewed, and suggestions for arch wire sequencing are made.
- Arch Form: Accurate and efficient methods for establishing a stable arch form is discussed, as well as arch wire coordination. The arch wire system presently used will be demonstrated.
- Vertical Dimension Control: The mechanics of opening deep bites and closing open bites is reviewed.
- Antero-Posterior Correction: An overview of Class II and Class III treatment options is presented, time permitting.
- Efficiency in Space Closure: The various methods of space closure are reviewed. Detailed information is presented on light force sliding mechanics.
- Finishing: The important aspects of finishing are developed in this final presentation.
- Matching the Orthodontic Appliance with Appropriate Treatment Mechanics: At each stage of treatment, the rational for use of the Avex orthodontic appliances are discussed.
- Selected cases from the other six courses will also be presented intermittently throughout the program.
