[Cephalometric evaluation of soft tissue in orthodontic treatment planning].

The starting point of an orthodontic treatment is represented by a complete and a correct diagnosis. Therefore the Authors investigated the need of a soft tissue analysis that is related to the University of Connecticut cephalometric analysis. The authors emphasize the importance of the vertical, horizontal and angular index in some patients with values different from the normal values. The soft tissue and esthetic data allow to finalize the orthodontic treatment to the esthetic improvement (besides occlusal) for the patients needs.

[Biomechanics or orthodontic treatment of tooth rotation].

The correction of dental rotation associated with a lingual or buccal version is possible to obtain with the action of a force system that is: consistent or inconsistent. The authors investigated a mandibular right second bicuspid rotated positively with its distal surface to the buccal. They decided to correct this rotation by using a consistent force system formed by a force and a moment applied to center of resistance (long axis in the occlusal view) and in lingual direction. It's possible to obtain in a consistent force system with the utilization of a straight wire or a "cantilever beam". The Authors decided to correct this rotation by using a cantilever beam of 017x025 wire with a vertical loop hooked over a heavier 021x025 wire between the first and the second molars. With an inconsistent system it's necessary to include a box loop so it is possible to make a variation and insert the wire from teh anterior or posterior just to obtain a consistent force system.
