Crown ethers are a class of cyclic compounds characterized by their ability to selectively complex cations, such as alkali metals. The point group of a crown ether generally depends on its specific structure and symmetry. For example, the most common crown ether, 18-crown-6, has a D_{3d} point group due to its symmetrical arrangement and the presence of multiple mirror planes and rotational axes. However, other crown ethers may have different point groups based on their size and substitution pattern.
Protists are a paraphyletic group because animals, fungi, and plants are the crown groups evolved from different lineages of the protists. They aren't included in the same group as protists taxonomically. This explains why the cladists consider the protist a paraphyletic group.
A stainless steel crown is typically crimped using a crimping instrument known as a crown crimper or crown contouring pliers. This tool allows the dentist to adjust the margins of the crown for a better fit and to ensure that it secures tightly onto the tooth before it is seated. By creating a more accurate adaptation to the tooth, the crimper helps improve retention and reduce the risk of crown dislodgment.
