• Unique Power Sources for Each Stage Promote Comfort, Speed and Stability by Peter C. Kesling, D.D.S., Sc.D.
    The prime source of tooth moving forces in the Differential Straight-Arch® Technique varies with each stage of treatment. This unique separation of power sources helps ensure the advantages of differential tooth movement. It promotes patient comfort, enhances rapid tooth movement and provides maximum stability.

  • Objectives Change With Time by Peter C. Kesling, D.D.S., Sc.D.
    Since the introduction of Tip-Edge brackets and the Differential Straight-Arch® Technique over ten years ago, the objectives of the early stages of treatment have changed. This has occurred as orthodontists around the world have gained more appreciation for the varied tooth moving capabilities and superb anchorage possibilities that lie within the ever-changing archwire slot.

    There has been a continual reduction in the number of tooth moving objectives in stage one and a corresponding increase of those in stage two. The result is a reduction in overall treatment times of some malocclusions—especially those having extractions, as stage two and posterior space closure begins sooner.

    The objectives of the first stage of Differential Straight-Arch treatment are now just three. [Read More]

  • The Outrigger®: The Noninterfering Answer to Noncompliance by Christopher K. Kesling, D.D.S., M.S.
    Over the years several appliances have been developed in attempts to minimize or eliminate the need for patient compliance to correct Class I and II malocclusions. Appliances such as the Eureka Spring®, Saif Springs®, Jasper Jumper®, the Pendulum and the Herbst® appliance were all developed to produce the desired sagittal correction with little or no dependence on patient cooperation. Virtually all of these appliances require the orthodontists to modify their treatment mechanics with some requiring timeconsuming impressions and laboratory fabrication.

    Appliances designed to protract the mandible and/or mandibular dentition such as the Jasper Jumper, Eureka Spring and the Herbst appliance deliver relatively heavy forces to the mandibular incisors that can rapidly produce proclination of the entire mandibular anterior segment. Many orthodontists have found that they must change the torque values of the mandibular incisor brackets to better control the tendency for this labial flaring of these teeth. [Read More]

  • Superior Anchorage Provides More Choices in Treatment Planning by Christopher Kesling, D.D.S., M.S.
    As the pendulum swings back and forth between extraction and nonextraction treatment regimens, most orthodontists have managed to avoid jumping exclusively on either bandwagon. Many realize that while nonextraction treatment is the preferred treatment plan whenever possible, there are certain situations where the extraction of teeth is required to provide the most stable treatment result and a well balanced facial profile.

    In the 1940s-1960s, when the extraction of teeth was indicated, the treatment plan was invariably the extraction of four first premolars. Today, however, due to improved diagnostic procedures and tools, the orthodontist has more choices when the extraction of teeth is indicated—choices that produce significantly better results and occlusions than can often be obtained with the extraction of the four first premolars.

    The superior anchorage control offered by the Tip-Edge appliance increases the extraction options even more. Anchorage concerns do not govern treatment mechanics as when treating with conventional edgewise and straight-wire techniques. [Read More]
