Dental appointments:
Please note for missed hygiene appointments and examinations a full charge for the appointment will be made. This will also apply for appointments changed or cancelled within two working days.
For surgeries missed or changed within five working days a charge of 50% of the full charge will be applied.
We will make every effort to see you at your scheduled appointment time. There will be no charge for changing or cancelling your appointment if given more than two working days notice for hygiene or examination appointments and more than five working days notice for surgeries.
No shows and last-minute cancellations disrupt the practice schedule and result in lost revenue, time in our clinician’s diaries and wasted resources. By not giving notice to cancel an appointment also removes the possibility of allowing us to offer this slot to others who are waiting.
We understand that in some cases being late for appointments is unavoidable. If you are going to be more than 10 minutes late to your appointment, we will not guarantee that you will be seen so please be aware that you may be asked to reschedule your appointment. This is to ensure the smooth running of our day and to enable fairness with all patients.
Text messages, email appointment reminders and telephone calls are a courtesy and you will receive these prior to your appointment. However, these cannot be relied upon. It is up to you to note your appointment in your diary and to attend at the appropriate date and time.
Dental payment policy:
When you book an appointment with us here at Implant Perio Clinic, we implement a deposit system which ensures fairness, reliability and consistency with practice operations. Receipt of your deposit is our confirmation of your commitment to attend your appointment.
Deposits will go towards the planned treatment fee. They are refundable, if appointments have been cancelled within the required timeframe.
– As a new patient you will be required to make a £200 deposit towards your consultation that is booked into the diary. The remaining balance will be taken on the day of the appointment
– As an existing patient, any appointment booked in the diary will require a deposit equating to 50% of the planned treatment cost
– For those with treatment plans that involve booking multiple appointments in the diary we will request that a proportionate deposit is to remain on your account until completion of your treatment plan
Fees:
We provide a printed estimate or treatment plan once this has been agreed upon by your dentist. We endeavour to have this ready for you after your appointment, however further planning may be involved so we aim to have the treatment plan sent across to you within 3-5 working days via email if this is the case.
We require you to read through your plan thoroughly and if you have any queries relating to the plan to bring them to the attention of our treatment coordinator prior to attending your next appointment. A signature will be required prior to commencing any treatment in order to ensure that you agree with the proposed treatment plan and fees involved.
If this plan changes due to radiographic or clinical findings, we will inform you and discuss this with you before proceeding with any procedures. Fees for treatment are due on the day that the treatment is provided. We do not operate an account in arrears facility and we require fees to be settled at the appointment, where treatment is provided. Treatment plans are sent to you in advance of your appointments so that you can keep track of what will be due on the day that you attend.
If you foresee that you may have difficulty in settling your balance on the day of your appointment, please get in touch with us as soon as possible to discuss your options with our team.
Fees for treatment where sedation has been administered, must be settled prior to the appointment to avoid financial transactions, or signatures being required, whilst still under the influence of the sedative.

Based in Marylebone, London, near Harley Street, he is known for his calm, meticulous, and long-term approach to treatment planning, with a strong focus on biological stability, function, and natural-looking outcomes.
With over two decades of clinical experience, Dr. Negahban has undertaken extensive postgraduate training in advanced implant surgery and restorative dentistry. He completed the Diploma in Implant Dentistry with the Royal College of Surgeons of England, widely regarded as one of the leading qualifications in implant dentistry in the UK.
His clinical work includes immediate implant placement, full-arch rehabilitation, guided bone regeneration, sinus augmentation, and the management of more complex implant cases, including patients referred by other clinicians. Dr. Negahban believes implant dentistry should be carefully tailored to the individual, balancing aesthetics with long-term maintainability and oral health.
Alongside clinical practice, Dr. Negahban has remained actively involved in implant education and was formerly a tutor on the FGDP Diploma in Implant Dentistry programme at the Royal College of Surgeons of England.
He is a member of the British Dental Association (BDA), the International Team for Implantology (ITI), the Royal College of Surgeons of England (RCS England), and the Faculty of General Dental Practice UK (FGDP UK).

Specialist Periodontist
DDS (Italy), PGCert Periodontics (New York), MSc Periodontology (London)
GDC: 78429Dr. Federico Tinti is a Specialist Periodontist with a particular interest in the long-term preservation of teeth, periodontal health, and the management of complex gum conditions. Based in Marylebone, London, near Harley Street, he is known for his thoughtful, meticulous, and prevention-focused approach to patient care.
Dr. Tinti believes healthy gums are the foundation of all successful dentistry — whether maintaining natural teeth, supporting cosmetic treatment, or ensuring the long-term stability of dental implants. His approach combines evidence-based periodontal care with a strong emphasis on education, maintenance, and minimally invasive treatment wherever possible.
He has extensive experience in the treatment of periodontal disease, gum recession, and complex restorative-periodontal cases, frequently working as part of a multidisciplinary team alongside referring dentists and implant clinicians. Patients particularly value his calm manner, honesty, and ability to explain even complex conditions in a clear and reassuring way.
At Implant & Perio Clinic, Dr. Tinti works closely with Dr. Pedram Negahban, Dr. Sanaz Tehrani, and the clinic’s experienced hygienist team to provide comprehensive periodontal, implant, and restorative care tailored to each individual patient. He strongly believes successful periodontal treatment is built on long-term collaboration, prevention, and supportive maintenance care, with hygiene therapy playing an essential role in maintaining healthy and stable outcomes for patients with periodontal conditions.
Alongside clinical practice, Dr. Tinti remains committed to continuing professional development and modern periodontal techniques, with a focus on achieving stable, maintainable, and natural long-term outcomes rather than short-term cosmetic solutions alone.
Outside dentistry, Dr. Tinti enjoys travelling, Italian culture and cuisine, and spending time with family and friends. Patients often appreciate his calm and approachable nature, which helps create a reassuring and comfortable experience even for those who may feel anxious about dental treatment.
Dr. Sanaz Tehrani is a German-trained dentist with a particular interest in Invisalign, minimally invasive aesthetic dentistry, and natural-looking smile enhancement. Based in Marylebone, London, near Harley Street, she is known for her warm, patient-centred approach and her belief that cosmetic dentistry should enhance a person’s appearance without compromising individuality or long-term oral health.
After qualifying in dentistry at RWTH Aachen University, Germany, in 2004, Dr. Tehrani relocated to the UK in 2005 and has since spent more than two decades caring for patients alongside her husband, Dr. Pedram Negahban. Together, they took over Implant & Perio Clinic on Portland Place, continuing a long-standing tradition of high-quality referral and patient-focused care.
Dr. Tehrani has extensive experience in private aesthetic dentistry, including Invisalign, whitening, composite bonding, and restorative smile rehabilitation. Her approach is conservative and detail-oriented, with an emphasis on harmony, facial balance, and results that age naturally over time. She believes dentistry should evolve with the patient, rather than follow temporary cosmetic trends.
Alongside aesthetic dentistry, Dr. Tehrani also has a strong background in general and emergency dental care, helping patients with everything from broken teeth and failing restorations to urgent discomfort and stabilisation treatment. Patients particularly value her calm manner, honesty, and ability to make even anxious individuals feel comfortable and understood.
While she enjoys the artistic and transformative side of cosmetic dentistry, Dr. Tehrani also finds great joy in treating children and young patients. Helping children feel relaxed, confident, and positive about visiting the dentist remains one of the most rewarding parts of her work and something that genuinely lights up her heart in daily practice.
Her passion for dentistry began following her own orthodontic treatment as a teenager, when she experienced first-hand the confidence and emotional impact that thoughtful dental care can have on a person’s life. This continues to shape the way she approaches patient care today.
Outside of dentistry, Dr. Tehrani enjoys travelling, social and charitable activities, and staying active through sport and fitness. She values human connection deeply and believes the most rewarding part of dentistry is the long-term relationships built with patients over time.
