The purpose of this study was to determine whether anterior and inferior displacement of the maxilla seen with rapid palatal expansion when done with a banded rapid palatal expansion appliance is significantly different from an occlusally bonded rapid palatal expansion appliance. It was hypothesized that the bonded appliance would limit unwanted displacement of the maxilla by producing vertical...

statement of the problem: refractory nocturnal enuresis possesses a heavy psychosocial burden for the affected child. only a 15% spontaneous annual cure rate is reported. purpose: this patient-level meta-analysis aimed to evaluate the efficacy of rapid palatal expansion to treat nocturnal enuresis among children. materials and method: a sensitive search of electronic databases of pubmed (since ...

Dissolution pressure and nozzle temperature effects on particle size and distribution were investigated for RESS (Rapid Expansion of Supercritical Solution) process. Supercritical CO2 was used as solvent and Ibuprofen was applied as the model component in all runs. The resulting Ibuprofen nano-particles (about 50 nm in optimized runs) were analyzed by SEM and laser diffraction pa...

distraction osteogenesis method (do) in bone lengthening and rapid midpalatal expansion have shown the great ability of osteognic tissues for rapid bone formation under distraction force and special protocol with optimum rate of one millimeter per day. periodontal membrane of teeth (pdm) is the extension of periostium in the alveolar socked. orthodontic force distracts pdm fibers in the tension...
