Forsus Appliance for Treatment of Class II, Division 2 Malocclusion in Adults
Volume 51 : Number 6 : Page 347 : Jun 2017
Treatment of a Class II, division 2 patient with no growth remaining has traditionally involved either orthognathic surgery or an orthodontic compromise requiring extraction of the upper first premolars. The authors present a third approach for consideration in borderline cases: nonextraction treatment using the Forsus Fatigue Resistant Device, a fixed-functional appliance.

Tunnel Traction Procedure for Deeply Impacted Canines and Resorbed Lateral Incisors
Volume 49 : Number 12 : Page 784 : Dec 2015
Three-dimensional radiographic studies have found root resorption in 38% of the lateral incisors and 23% of the central incisors associated with impacted canines. Although such damage can occur even when canines erupt normally, the key to success in treating an impacted canine is to achieve correct positioning in the dental arch without causing periodontal defects. A combined surgical-orthodontic approach called the tunnel traction procedure enables physiological eruption of a deeply impacted upper canine while preserving long-term periodontal health. Introduced by Crescini and colleagues, the technique is based on the concept of infracrestal guided eruption. It is recommended for use in cases where the corresponding deciduous teeth provide sufficient space for eruption of the impacted canines.
