Visual Essay Adjacent Implants in the Anterior Maxilla Surgical and Prosthetic Concepts Eric Van Dooren, DDS Key Words: prosthetic-soft tissue interface, immediate implant placement, anterior implant restorations Introduction To optimize tooth proportions and esthetic outcomes in anterior implant restorations, the challenge is really not achieving “white esthetics.” Instead, the difficulty is in addressing the prosthetic-soft tissue interface. Particularly in implant dentistry, it can become quite onerous to establish a balance between pink and white at this critical junction. Single-tooth anterior implant restorations are very predictable in most clinical situations, if certain guidelines are respected. The placement of two adjacent implants in the esthetic zone, especially while treating a unilateral defect, has always been a challenge. To achieve the longest-lasting, most esthetically pleasing restoration, a strict surgical and prosthetic protocol must be respected. This case presentation will describe the clinical protocol and concepts for immediate implant placement when replacing adjacent lateral and central incisors with implant-borne restorations. 42 Summer 2012 • Volume 28 • Number 2 Van Dooren Journal of Cosmetic Dentistry 43 Case Presentation Diagnosis and Treatment Planning Figures 1 2: A 25-year-old woman w
