The segmental mechanics - An efficient method to re - duce treatment duration in severely crowded cases
نویسنده
چکیده
Segmental mechanics consists of multiple wire cross-sections in different segments of the arch. The advantages of segmental mechanics in comparison with continuous mechanics are a statically determinate force system, relatively constant force, minimal side-effects on the anchorage unit, minimal arch wire fabrication, decreased treatment duration and enhanced esthetics. Individual retraction of the canine using segmental mechanics prior to unraveling of anterior teeth crowding helps in preventing round tripping of the anterior teeth and thereby facilitating a reduction in treatment time. The following article presents several case reports that highlight the efficiency of segmental mechanics in the reduction of treatment duration in severely crowded case

متن کاملPRIMARY TORSION AND IDIOPATHIC SEGMENTAL INFARCTION OF OMENTUM
Torsion and infarction of the greater omentum are two rare clinical situations which present as an acute abdomen. Nevertheless, knowledge concerning these two problems can help the surgeon in proper diagnosis and treatment. Since the first report on primary torsion by Eitel in 1899, a few hundred more have been reported and some collective reviews published to date. In this study we will p...

ABSTRACT Primary or spontaneous infarction of omentum is a rare disease producing acute abdominal condition. This is due to vascular changes in circulation of greater omentum. Infarction can be caused by torsion of omentum around the adhesion band following an operation, or it can occur spontaneously without an adhesion and operation. Rarely this condition is not due to torsion a...
