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).
September follows on from Quinitlis and Sextilis, in that it comes from the Latin septem, âsevenâ. As with those (and the rest of the calendar), the numbering is a bit off now: September was originally the seventh month in an ancient Roman ten-month calendar, which started with March.
