The material [e.g., nylon 12 beads, polyetheretherketone (PEEK) milling blank, thermoplastic sheet] is manipulated [e.g., by melting and moulding, or computer-aided techniques (dental CAD/CAM)] to form the shape needed for the patient. After application, this material cannot be refabricated.</gmdnPTDefinition><implantable>false</implantable><gmdnCodeStatus>Active</gmdnCodeStatus></gmdn></gmdnTerms><productCodes><fdaProductCode><productCode>EBF</productCode><productCodeName>Material, Tooth Shade, Resin</productCodeName></fdaProductCode><fdaProductCode><productCode>EBG</productCode><productCodeName>Crown And Bridge, Temporary, Resin</productCodeName></fdaProductCode></productCodes><deviceSizes/><environmentalConditions/><sterilization><deviceSterile>false</deviceSterile><sterilizationPriorToUse>false</sterilizationPriorToUse><methodTypes/></sterilization></device>
