Our practice history

Implant & Perio Clinic at 57 Portland Place, London, was established in 1989 by Dr Alan Sidi, a greatly respected specialist periodontist. Since then, we’ve been dedicated to delivering the best quality treatment in the fields of periodontics and dental implant surgery.

In 2024, Dr Pedram Negahban took over as owner and principal dentist after Dr Sidi’s retirement. He is proud to continue the clinic’s legacy of exceptional treatment and friendly and understanding care in a comfortable and safe environment.
