Differential tooth movement has been associated with the Begg technique and ribbon arch-type brackets since 1954. Its efficiency and effectiveness have been demonstrated and documented over the past 30 years. A relatively new edgewise-type bracket has been designed to permit differential tooth movement within predetermined limits. The following case reports describe the treatment of three differing malocclusions by means of Tip-Edge brackets and straight arch wires. The first was treated with the aid of mesiodistal crown size reduction, the second with the pretreatment removal of the four first premolars, and the third without the removal of any permanent teeth.

Tip-edge, a relatively new edgewise-type bracket, provides a dynamic interaction with either round or edgewise arch wires. This can promote the achievement of treatment goals, increase patient comfort, and enhance ease of appliance manipulation. The various relationships available with the Tip-edge arch wire slot, arch wires, and special auxiliaries and their effects are explained and illustrated in sequence as they would occur during the course of treatment.

The purpose of this article is to introduce an edgewise-type bracket that permits both initial Begg tooth movement and final edgewise torque and tip control with straight arch wires. Analysis of individual tooth movements during treatment of all types of malocclusions with the Begg technique shows that all teeth tend to tip distally or toward extraction sites if present. Given this tendency, it is possible through precise removal of diagonally opposed corners of conventional edgewise slots to permit desired initial free crown tipping yet provide predetermined secondary control of root uprighting as required for each tooth. Treatment can be carried out with four straight arch wires, two 0.016 inch (0.406 mm) and two 0.020 inch (0.508 mm), in conjunction with selective applications of 2 ounce (57 g) forces. Mesiodistal root uprighting and labiolingual torque are achieved with uprighting springs and torquing auxiliaries. Special elastomeric ties and torquing flaps in conjunction with the unique brackets and round molar tubes provide the final option to capture all preangulations (tip and torque) from two full-sized, highly resilient rectangular arch wires.
