## DEVICE DESCRIPTION

The XP1 15° Angled Abutment is intended to be placed into a dental implant to support prosthetic restorations in partially or fully edentulous mandibles and maxillae. The angled abutment can be used for single or multiple-unit restorations and is intended for cement-retained crowns.
