It is a two-piece device composed of an anchorage component (implant body) in the form of a threaded screw that is implanted into bone, and a retention component (implant abutment), typically attached to the anchorage component after implantation, that protrudes through gingival tissues to support the prosthesis.</gmdnPTDefinition><implantable>true</implantable><gmdnCodeStatus>Active</gmdnCodeStatus></gmdn></gmdnTerms><productCodes><fdaProductCode><productCode>DZE</productCode><productCodeName>IMPLANT, ENDOSSEOUS, ROOT-FORM</productCodeName></fdaProductCode></productCodes><deviceSizes><deviceSize><sizeType>Device Size Text, specify</sizeType><size unit="" value=""/><sizeText>Outer Diameter 3.5-5.0mm</sizeText></deviceSize></deviceSizes><environmentalConditions/><sterilization><deviceSterile>true</deviceSterile><sterilizationPriorToUse>false</sterilizationPriorToUse><methodTypes/></sterilization></device>
