A Simplified Technique for the Fabrication of Esthetic and Functional Space Maintainers in Pediatric Dentistry

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Introduction Premature loss of primary molars remains a frequent clinical problem in pediatric dentistry and may lead to space loss, occlusal disturbances, and the need for future orthodontic intervention. Conventional space maintainers, such as the band‐and‐loop appliance, are effective in preserving arch length but do not restore occlusal ...

Bulk, rare earth and other trace elements in Apollo 14 and 15 and Luna 16 samples [PDF]

The chemical abundances were measured by instrumental and radiochemical neutron activation analysis in a variety of lunar specimens. Apollo 14 soils are characterized by significant enrichments of Al2O3, Na2O and K2O and depletions of TiO2, FeO, MnO and ...

Timing of Metamorphism and Deformation in the Neoarchean Quetico Metasedimentary Belt, Superior Craton, Constrained by Garnet Trace‐Element Mapping and Lu–Hf Geochronology

Journal of Metamorphic Geology, EarlyView.
ABSTRACT The Quetico subprovince of the Superior Province is among the largest metasedimentary belts globally and provides evidence of tectonic processes at play during the final stages of Archean cratonization. Although previous studies have shown that deformation and metamorphism of the 2.7‐Ga turbiditic protolith resulted in regional subvertical ...

Thermal Buffering, Heat Advection and Crustal Thinning in the Ryoke Metamorphic Complex, Yanai, Southwest Japan

Journal of Metamorphic Geology, EarlyView.
ABSTRACT The metamorphic zoning and geothermobarometry of the Ryoke metamorphic complex in the Yanai area, southwest Japan, show that its thermobaric structure was buffered by the dehydration melting of biotite. The temperatures over most of the area covered by the three high‐grade zones (8.5‐ to 19.0‐km depth) are consistent with those of the ...
