In some embodiments, the present disclosure relates to a chemical mechanical planarization (CMP) tool. The CMP tool includes a carrier and a malleable membrane coupled to the carrier and having a lower surface facing away from the carrier. The lower surface of the malleable membrane includes a first malleable material within a central region of the lower surface and a second malleable material within a peripheral region of the lower surface, which surrounds the central region. The first malleable material provides the central region of the lower surface with a first stiffness and the second malleable material provides the peripheral region of the lower surface with a second stiffness that is different than the first stiffness.

The present invention discloses a method of producing an orthodontic transpalatal arch having multiproperties. The present invention provides the transpalatal arch which is easy to prepare without the need of laboratory, cast, and impression. It includes the steps of (a) taking a sterile electrical wire (01) wherein the electrical wire (01) is pushed to follow the palatal contour, opposite to the area of the upper first right and left side molars with the help of a band pusher to record all texture and contour of the palatal area from upper left first molar to upper right first molar, (b) arranging a twistflex (02) inside a plastic tube (04) piece, (c) fixing the plastic tube (04) with twistflex (02) to the wire in a similar shape of the wire recorded for the palatal area by a plurality of hair clamps (05), (d) pouring a resin material inside the plastic tube (04) based on the required properties of the transpalatal arch, (e) setting the resin material along with the twistflex (02), and (f) cutting the plastic tube (04) to release the set resin material with the twistflex (02).
