title: Examples of model-free implant restorations using Cerec inLab 4.0 software.
abstract: This case report demonstrates two ways to fabricate model-free implant restorations with the Cerec inLab 4.0 software. Because the patient, a woman with a history of periodontal disease, did not wish to have a removable partial denture, implant therapy was planned for the restoration of her edentulous areas 14/15 and 24/25. In addition, the restoration was to provide functional relief of the natural maxillary anterior teeth. The two implants for the first quadrant were planned as single-tooth restorations. Each was designed as a full contour implant supra-structure using the Cerec Biogeneric abutment design technique. After completing the design phase, each restoration proposal was split into two parts: a zirconia abutment and a lithium disilicate crown. For the restoration of the second quadrant, custom 20-degree-angled abutments were individualized and acquired with the Cerec camera. A block crown was then designed, milled in burn-out acrylic resin, and fabricated from a lithium disilicate glass-ceramic ingot according to the press ceramic technique. Additionally methods of provisional restorations are discussed.
