The methods include providing a soluble material in particulate form and forming a packed region from the material. The methods also include contacting a flowable polymeric material with the packed region such that the polymeric material is disposed in voids in the packed region. The polymeric material is then at least partially solidified. The soluble material is then removed such as by solvent washing to thereby produce desired porous articles.

Publication number: 20170333157Abstract: Apparatus and methods for removing a dental crown from a tooth. Chemical bonds within an adhesive, between the adhesive and the crown, and between the adhesive and the tooth may secure the crown to the tooth. The chemical bonds may be weakened. After weakening the bonds, the crown may not be securely affixed to the tooth. After weakening the bonds, the crown may be easily removed from the tooth. The bonds may be weakened by applying ultrasonic waves to the adhesive. Sonic energy of the waves may heat the adhesive. The bonds may be weakened by positioning the adhesive within an electric field. The bonds may be weakened by applying heat to the adhesive. The heating may cause particles within the adhesive to expand. The electric field and/or the sonic energy may be applied via an electronic tool.Type: ApplicationFiled: May 19, 2017Publication date: November 23, 2017Inventors: Gopi Soundararajan, Mohammad Reza Mehrabi, Matteo R.
