Results of our study showed that using therapeutic lasers with green, blue, red, and infrared wavelengths may accelerate healing process. This trend is more obvious in red and infrared groups especially after acute phase, however, this effect was neither statistically nor clinically significant.

There are numerous intra-oral appliances that are used for many purposes in orthodontic practice. Some popular instances include those for anchorage preservation, distalizing plates, and expansion appliances. In maximum anchorage extraction cases, which are serious challenges for orthodontists, none of intra-oral devices can preserve the anchorage precisely. Butterfly arch with its unique design, configuration, and biomechanical properties is introduced here as a device that could enhance the posterior anchorage meticulously. In addition, there are several advantages mentioned here to present the importance of the appliance to preserve the vertical and transverse dimensions as well.

This research is conducted to evaluate the bimaxillary protrusion in adult Filipino subjects according the inclusive criteria of this study to investigate the behavior of the discrepancy. Seventy cephalograms were selected according the inclusive and the exclusive criteria for bimaxillary protrusion. Then all were traced and analyzed by the cephalometric analysis with related variables which used in the study. Results of the study showed that the patients with bimaxillary protrusion indicated the high angle mandibular plane partly due to excessive upper posterior dentoalveolar height and partly because of short ramus. The patients showed hyperdivergent facial pattern with decreased overbite which demonstrated skeletal openbite and long face pattern. Filipino patients with bimaxillary protrusion have varied degrees of skeletal vertical discrepancy which makes the primary horizontal discrepancy more complicated. Hence, vertical consideration before any corrective treatment should take into the account regarding the limitations of the orthodontic treatment, especially in the severe cases.
