Technique. novel cantilever spring which is made of 0.014-inch stainless steel wire, is beneficial to be used in cases of canine impaction because of its safety and low force/deflection ratio. It is common in daily orthodontic practice to encounter im-pacted canines which occur in approximately 2 percent of the population (1,2). This design of bridge has been superseded. A posterior molar is usually the tooth that gets a crown and acts as the support for the pontic tooth. This increases the effective length of the wire improving its flexibility. 1 Cantilever springs and segmental mechanics with loops 2 have been proposed for uprighting; more recently, one to three mini-implants have been used to provide skeletal anchorage. Brackets were non‐specific. 3. This could be explained by the orthodontic pressure concentration associated with the direction of the force produced by the spring.
