The Procera crown â Procera is a milled ceramic on the inside with a more traditional porcelain baked onto the outside. The advantage of Procera is its exceptional strength. However, the milled ceramic core is opaque white, so many cosmetic dentists feel that it isnât as natural-looking as the more translucent materials.
Origin of the Names of the Months. 1  October: Eighth month (octo, Latin for 8) in the Julian (Roman) calendar. 2  November: Ninth Roman month (novem, Latin for 9).  December: Julian (Roman) year's tenth month (decem, Latin for 10).
The first is that the month is named after the Roman goddess Juno, the goddess of marriage and the wife of the supreme deity Jupiter; the second is that the name comes from the Latin word iuniores, meaning younger ones, as opposed to maiores (elders) for which the preceding month May (Maius) may be named.
