2009/12/24
Distraction osteogenesis method (Do) in bone lengthening and rapid midpalatal expansion have shown the great ability of osteognic tissues for rapid bone formation under distraction force and special p...
A Numerical Simulation of Orthodontic Tooth Movement Produced by a Canine Retraction Spring
Orthodontics Canine retraction Finite element method
2009/9/14
Tooth movements produced by a canine retraction spring were calculated. Although a gable bend and an anti-rotational bend were incorporated into the spring, the canine tipped and rotated initially. Re...

Evaluation of upper lip retraction with retraction of the incisor edge in 41 Class II cases showed an average ratio of 1:3.8. Increase in the nasolabial angle was found to be associated with chang...
The Effect of Gingival Fiberotomy on Orthodontic Cuspid Retraction in Cats
Gingival Fiberotomy Orthodontic Cuspid Retraction Cats
2009/3/4
Distal tipping forces were applied to the maxillary cuspid teeth of five domestic cats. Surgical elimination of the gingival attachment of one tooth in each cat resulted in greater distal crown mo...
