Realities and limitations in the management of the interdental papilla between implants: three case reports.

A predictable, aesthetic result is sometimes difficult to achieve when two or more adjacent implants are placed in the anterior maxilla. Maintenance of the distance from the interproximal crest of bone to the contact point influences the presence or absence of the interdental papilla. The design of the coronal portion of implants currently in the market and the contour of the implant-abutment junction may further affect the biology and reformation of the papilla between two adjacent implants. Through a series of case reports, parameters influencing implant placement are presented.
