An experimental study on mechanical behavior and stability of internal screw fixation (ISF) of sagittal split ramus osteotomy has been carried out. A stress freezing method in a three-dimensional photoelastic experiment was used. Four ISF's that utilized different screw placement patterns were used for photoelastic analysis: (1) 3 screw linear pattern(More)
The facile synthesis of ZnS-AgInS2 (ZAIS) as cadmium-free QDs and their application, mainly in solar cells, has been reported by our groups. In the present study, we investigated the safety and the usefulness for labeling and in vivo imaging of a newly synthesized aqueous ZnS-coated ZAIS (ZnS-ZAIS) carboxylated nanoparticles (ZZC) to stem cells. ZZC shows(More)
Various screw placement patterns have been described for fixation of the sagittal split ramus osteotomy. This study is a comparative evaluation of 3 different screw placement patterns on the rigidity of the sagittal split ramus osteotomy. Twenty cadaver mandibles were used to compare the load strength of triangular pattern, oblique linear pattern versus(More)
