Benzylbutylphthalate (BBzP), also called n-butyl benzyl phthalate (BBP) or benzyl butyl phthalate, is a phthalate, an ester of phthalic acid, benzyl alcohol and n-butanol. It comes under trade names e.g. Palatinol BB, Unimoll BB, Sicol 160, or Santicizer 160. It is mostly used as a plasticizer for PVC. It is considered a toxicant.
Teeth worn down by bruxism. When teeth have been worn down from a habit of tooth clenching and grinding: 1  All of the upper front teeth usually have a similar length. 2  Instead of having gently rounded contours, their biting edges are frequently worn straight across.old has a wear coefficient that's similar to enamel, which means it won't cause excessive damage to opposing teeth. And since it's a metal, crowns made out of it are unlikely to fracture. Of course, the big disadvantage of this type of restoration is its appearance.
A full denture is made to restore both the teeth and the underlying bone when all the teeth are missing in an arch. A smaller version is the fixed partial denture, also known as a fixed bridge, which can be used if generally healthy teeth are present adjacent to the space where the tooth or teeth have been lost.The partial is anchored to the surrounding teeth by attachment to crowns, or caps, that are affixed to the healthy teeth.he quality of the denture's fit can be controlled in two ways. Relining is a process by which the sides of the denture that contacts the gums are resurfaced. Such adjustments are necessary because the dental impressions used to make dentures cause the gums to move.
