Results A two-year follow-up revealed there occurred butment caries,luxated butment,and overlain residual root gingivitis,even on the rise,while the alveolar ridge showed no uneven absorption.
In the light of different position, the mesiodens were extracted respectively by the technique of labial ladder-shaped flap, palate-tongue shaped flap or incision of alveolar ridge crest.
Ridges on achene surface in Senecio and Taraxacum are useful for absorbing small particles or control-ling surface temperature.Spinule on achene of Taraxacum may be fit for epizoochore.
Rigatoni is a form of tube-shaped pasta. It is larger than penne and ziti. Rigatoni is usually ridged and the tube's end does not terminate at an angle, like penne.
In both types of feather, the barbules that extend from the barb ramus grow from a single layer of cells, called the barbule plate, on the periphery of the barb ridge.
Or through high ridge in a field, covering terra, increasing the temperature of earth, increasing the thickness of dust and frowst in the day time can all be the methods of toting temperature.
In a pennaceous feather, the barbs grow helically around the tubular feather germ and fuse on one side to form the rachis.Simultaneously, new barb ridges form on the other side of the tube.
