- Headgear and Tip-Edge–Do They Mix? by Dr. Richard Parkhouse, Consultant Orthodontist
Tip-Edge succeeds in combining the ease of tooth movement of the earlier Begg appliance with the precision finishing of the “straight wire” appliance. Because of this, it successfully exploits the use of Class II elastics in the treatment of the majority of Class II cases. Indeed it is common everyday experience, among Tip-Edge clinicians, to be able to treat large overjets and deep overbites without the need for anchorage reinforcement. This is in contrast to conventional edgewise derived systems, in which each bracketed tooth is effectively an “anchorage unit,” requiring to be driven to its finishing position by bodily movement. It is hardly surprising, therefore, that straight wire orthodontists so regularly need to boost posterior anchorage, frequently with headgear, to achieve a result comparable to what Tip-Edge can achieve using only Class II elastics.
The main reason for preferring elastic traction to headgear is convenience to the patient. It requires a highly motivated patient to persevere with headgear wear, compared with intermaxillary elastics, while noncompliance with elastics can frequently be overcome with the use of Outrigger® traction hooks. There is no doubt that the Tip-Edge bracket lends itself ideally to Class II elastics, since it allows the use of very light forces, thereby avoiding some of the pitfalls of Class II traction, such as elongation of maxillary incisors and clockwise rotation of the occlusal plane. Also, teeth seem willing to intrude more readily, if allowed to tip slightly in the process, which greatly helps overbite reduction. Sadly, many orthodontists, previously familiar with the Begg technique, have attempted to employ the same Class II mechanics with straight wire brackets, but with disappointing results, due to increased anchorage resistance—both vertically and horizontally.

- Updated Stage Two Mechanics and Objectives by Christopher K. Kesling, D.D.S., M.S.
Goals of the second stage of the Differential Straight-Arch® Technique have been expanded to seven. Today stage two goals include correction of posterior crossbites, final correction of Class II or III molar relationships, leveling of anchor molars, and perhaps most importantly the correction of midline discrepancies.

- Active or Passive Treatment Starts by Richard T. Conlin, D.D.S.
When Dr. P. Raymond Begg designed an appliance that would best open the bite and place the teeth over their natural apical base, he saw the necessity to use:
1. A friction free bracket.
2. A hard, resilient .016″ archwire.
3. Light elastic forces.
This became the standard. With the new technology, more options became available and it has become possible to maintain the classical standards with different approaches. This paper discusses two basic options for starting a case, either active or passive. They are made possible with the introduction of nickel titanium archwire, and Tip-Edge brackets. [Read More]
- Tip-Edge Treatment as a Practice Management Tool: Overhead Drops Below 40% by Michael J. Mele, D.D.S., M.S.
If you are an avid reader of the TIP-EDGE TODAY®, then you are well versed with the tremendous treatment advantages that Tip-Edge provides. For the past three years I have implemented and embraced this technique. As my clinical skills have improved, so have my treatment results and my practice’s profit margin.
Forcing myself to improve and understand the subtleties of the Tip-Edge technique, I learned after only one year that I could schedule patients with longer appointment intervals. Patients in stages one and two of treatment would have originally been scheduled every 4 to 6 weeks; now, they are scheduled every 8 weeks.
In addition, most all stage three patients are regularly seen every 12 weeks. Of course, for doctors concerned with “checking-up on patient compliance,” good cooperation with elastics would have already needed to be established by stage three.
Before I knew it, my practice began treating more patients per month without lengthening treatment time. In fact, using Tip-Edge has actually lessened my overall treatment times. [Read More]
