Active vertical control is critical in the treatment of hyperdivergent skeletal Class II malocclusion. The mechanics have been well shown as successful fixed appliance system with temporary anchorage devices (TADs); however, there are few relevant case reports clear aligner therapy (CAT). present report describes a severe using CAT extraction four premolars. was performed TADs, which facilitate...

A case of severe maxillary hypoplasia in a 21 years old male Thai patient with a complete unilateral cleft of primary and secondary palates treated by internal distraction osteogenesis for maxillary advancement is presented. Initial evaluation showed Class III malocclusion with total crossbite and Class III skeletal malrelationship. Two intraoral distractors were placed following a Le Fort I os...

A1. The temporary skeletal anchorage device used in this study, C-implant, requires higher removal torque compared to other orthodontic mini-implants because of its greater osseointegration potential. It also means that the C-implant allows application of multi-directional force system such as retraction combined with intrusion by concurrent use of intraand intermaxillary elastics. In such case...

Cross bite is a condition where one or more teeth may be abnormally malposed buccally or lingually or labially with reference to the opposing tooth or teeth. Cross bite correction is highly recommended as this kind of malocclusion do not diminish with age. Uncorrected cross bite may lead to abnormal wear of lower anteriors and cuspal interference, mandibular shift resulting in mandibular asymme...

The aim of this research is to calculate the elastic constants and Bulk modulus of Cu-20 wt% Ni random Nanoalloy. The molecular dynamics simulation technique was used to calculate the mechanical properties in NPT ensemble. The interaction between atoms as well as cohesive energy in the Nanoalloy modeled systems was calculated by Morse et al. two body potential. Also the temperature of the syste...

various basidiomycetes and deuteromycetes, grown in liquid and solid culture media, were compared for their laccase-producing ability and for the inducing effect of soil and agricultural residues on laccase production. laccase activity in extracts of all solid media was higher than that of the liquid media. in liquid cultures, fungal laccase activity in ex-tracts of pea (pisum sativum) straw-tr...

DNA is generally considered to be chemically rather inert, but self-cleaving DNA molecules have recently been isolated from in vitro selection experiments; their properties advance the idea that, like RNA, DNA can serve as both a catalyst and an information storage medium.
