How far below the adjacent teeth's CEJ should the platform of an implant in the esthetic zone be placed?

In the context of placing implants in the esthetic zone, the platform of the implant should ideally be positioned approximately 2 mm apical to the adjacent teeth's cemento-enamel junction (CEJ). This placement is important for several reasons.

First, positioning the implant platform 2 mm below the CEJ helps ensure that the final restoration matches the natural contours and aesthetics of the surrounding teeth. If the implant is placed too high, it may lead to a situation where the crown appears too prominent, which is particularly critical in the esthetic zone where visual appearance is paramount.

Second, this placement aids in the management of soft tissue aesthetics. Placing the implant at this depth allows for adequate soft tissue integration and helps create a natural-looking emergence profile for the prosthetic crown. This helps mimic the natural gingival architecture seen in natural teeth.

Additionally, the 2 mm distance is informed by the biological width necessary to maintain healthy peri-implant tissues and minimize the risk of bone loss around the implant. Overall, this approach enhances both the functional and aesthetic outcomes of the implant procedure in the esthetic zone.
