IPS e.max CAD Abutment Solutions is intended for use in partially or fully edentulous mandibles and maxillae in support of single cement-retained restorations. The system comprises three parts: IPS e.max CAD mesostructure, Ti base and CAD/CAM software. The IPS e.max CAD mesostructure cemented to the Ti base is recommended for two-piece hybrid abutments for single tooth restorations and hybrid abutment crowns, used in conjunction with endosseous dental implants. The compatible Implant systems, Ti bases and CAD/CAM systems are shown below: Implant systems: Nobel Biocare Replace (K020646), Nobel Biocare Activem (K071370), Straumann Bone Level (K053088, K062129, K060958), Biomet 3i Osseotite (K980549) CAD/CAM Systems: Sirona inLab and Cerec SW 4.2 and above. For the titanium base Straumann Bone Level 3.3 L the indication is restricted for replacement of single lateral incisors in the maxilla and lateral and central incisors in the mandible.

IPS e.max CAD Abutment Solutions is intended for use in partially or fully edentulous mandibles and maxillae in support of single cement-retained restorations. Titanium bases are a premanufactured prosthetic component directly connected to dedicated endosseous dental implants. The Titanium base is used for adhesion to mesostructures to restore function and esthetics in the oral cavity. IPS e.max CAD Abutment Solutions are lithium disilicate blocks in various sizes. One side of the block is mounted to a mandrel that will be inserted into the spindle's clamping chuck of the grinding machine. The connection geometry to titanium bases is prefabricated, i.e. already include in the shipped block. Connection geometries fit select Titanium Bases marketed by Straumann, Nobel Biocare and Biomet 31 as identified in the Intended Use section. The mesostructure is individually designed and milled using CAD/CAM Technology into the shape of a hybrid abutment or hybrid abutment crown as designed by the trained professional using the Sirona inLab and Cerec SW 4.2 (or higher) software.. The device serves as the esthetic mesostructure which is extraorally cemented onto a Titanium Base. The two piece abutment is mounted onto the implant and fixed with a screw.

This document describes the IPS e.max® CAD Abutment Solutions, a dental device consisting of a lithium disilicate ceramic mesostructure cemented to a titanium base, designed for single cement-retained restorations in conjunction with endosseous dental implants.
