J Esthet Restor Dent 2021 Mar 7. Epub 2021 Mar 7.

Department of Prosthodontics, Shanghai Ninth People's Hospital, College of Stomatology, Shanghai Jiao Tong University School of Medicine, Shanghai, China.

Objective: This article introduced a modified method to fabricate an individualized abutment-crown integrated provisional restoration for single-tooth implant restoration in the esthetic zone, which created a satisfactory peri-implant soft tissue architecture.

Clinical Considerations: Three months after the implant placement, the individualized abutment-crown integrated provisional restoration was designed and fabricated in the laboratory, by referring to the profile of natural contra-lateral tooth digitally, and seated on the implant afterwards. The peri-implant soft tissue architecture was evaluated and the Pink Esthetic Score (PES) was recorded. Read More
