Single-tooth implant restoration in esthetic zone with immediate provisionalization: a clinical report.

Objectives: This clinical report describes a single-tooth implant restoration in a fresh extraction socket in the anterior maxilla, with immediate provisionalization and CAD-CAM zirconia final prosthesis. Methods and Materials: Due to a traumatic injury, an esthetically concerned 40 year-old female patient was treated with an atraumatic extraction of a maxillary central incisor, which was immediately substituted with a single implant. Immediate provisionalization was performed using a screw-retained resin crown. Two months after surgery, the patient was fitted with a final all-ceramic single crown cemented on a CAD-CAM customized zirconia abutment. Results: Healing was predictable, with the implant neither showing mobility nor presenting pain. The zirconia crown was undamaged. The patient was pleased with treatment time and esthetic result. Discussion: Implant treatment with immediate provisionalization offers several advantages: optimal esthetics is achievable as bone and soft tissue architecture is maintained; patients are provided with a fixed temporary restoration at the time of surgery; treatment time is shortened, as second stage surgery is eliminated. Furthermore, the fresh extraction socket is a metabolically active region with good potential for bone repair and successful implant placement. Conclusions: Optimal mechanical performances and excellent esthetics were achieved in the anterior sites by means of a CAD-CAM zirconia customized abutment and crown. Clinical Significance: In cases where clinical conditions are favourable to the placement of an implant into a fresh post-extraction socket, such a treatment modality offers several advantages over a conventional approach.
