Limitations, open questions
Without regenerative treatment the extraction of anterior teeth with prominent roots frequently results in the resorption of the thin buccal plates. Although occasionally patients
demonstrate no resorption without grafting most benefit significantly from filling the extraction socket with Bio-Oss®.

Treatment concept of Prof. Dr. Myron Nevins, Harvard
School of Dental Medicine, USA

Clinical situation in a patient after extraction of 2 prominent
roots: One buccal bone plate is partially intact, the other is lost.

> Maintenance of the buccal bone plates with Bio-Oss® granules
> Teeth with thin buccal bone plates
> In anterior region
