This page sets out exactly what is covered, what is excluded, and what you need to do to keep your warranty valid.
Our Warranty at a Glance
- Biological Warranty - 3 Years. Covers implant-related surgical revision if an implant fails.·

Where a failure is covered, 21D will:
- Remove or replace the failed implant

Revision surgery will only be carried out where it is clinically appropriate and in your best interests. If revision is unsuitable, alternative treatment options will be discussed with you.

- Damage caused by trauma or accidents
- Aesthetic revisions after you have approved your final prosthesis
Repairs or replacements outside these conditions may be chargeable.
Keeping Your Warranty Valid
To maintain your warranty, the following conditions must be met:
A. Annual Maintenance Visits and Post Surgical Review
- You must attend an annual maintenance appointment at a 21D clinic. The fee for this appointment is £250 and must be completed within 60 days of your due date each year.
- These appointments allow us to monitor implant health, check your bite, measure gum stability and ensure your prosthesis remains in optimal condition.
- Attendance at any clinically required post-surgical review appointments is mandatory to maintain warranty validity. Failure to attend may result in partial or full invalidation of warranty cover.
B. External Providers
You may see any dentist you choose, but:
- Any damage, complications or issues caused by external clinicians are not covered by your warranty.
- This includes hygiene treatment, repairs, adjustments, or any dental intervention involving the implants or prosthesis.
C. Smoking or Vaping
- Smoking or vaping significantly increases the risk of implant complications.
Issues caused or worsened by smoking/vaping are excluded from warranty cover.
D. Oral Hygiene Compliance
- You must follow the hygiene and aftercare instructions provided by 21D.
Poor oral hygiene leading to peri-implant issues may invalidate warranty claims.
E. Medication & Health Updates
- If you are prescribed medication after surgery, you must inform us if you stop taking itor have adverse effects. Changes in your general health (e.g., diabetes control, autoimmune conditions, bruxism) may affect implant outcomes and must be communicated to us.
F. Trauma or Misuse
Your warranty does not cover damage caused by:
- Chewing hard objects (e.g., ice, pen lids, bones, hard nuts)
- Using your teeth as tools
- Sports injuries or accidental trauma
- Grinding/clenching where a night guard was recommended
- Failure to wear a night guard when advised
Financed Treatment
Where treatment is funded in whole or in part through a third-party finance provider introduced by 21D, the finance provider may confirm to 21D whether loan repayments are up to date. This information may be shared for the purposes of administering the commercial arrangements between 21D and the finance provider. If loan repayments are not up to date, 21D may, at its discretion, defer or decline to provide non-urgent appointments, maintenance visits, or warranty-related work until the account is brought up to date. This does not affect your statutory rights or access to urgent or emergency care where clinically required.
Warranty Exclusions
Your warranty does not cover:
- Trauma or accidental damage
- General wear and tear of the prosthesis
- Cosmetic dissatisfaction after final approval
- Changes in appearance over time (colour shift, wear, staining)
- Issues arising from smoking/vaping
- Poor oral hygiene or untreated gum issues
- Missed annual maintenance visits
- Work, damage or complications caused by external providers
- Fractures of PMMA/veneer caused by excessive force
- Health changes that impact implant stability
These exclusions are consistent with standard implant industry practice.
Any non-clinical items supplied by 21D (including the goody bag with electric toothbrush, water flosser and similar accessories) are provided as complimentary gifts. These products are not part of your clinical treatment and are therefore excluded from all warranties. Replacement or continued use of such items remains the responsibility of the patient.
Our Materials and Prosthetic Design
Your final prosthesis is made using a custom-milled titanium substructure and a high quality PMMA prosthetic material, engineered by our in-house laboratory, 21D Bioengineering. This material combination ensures durability and strength, while offering a natural aesthetic. Some level of wearover time is normal for any prosthetic material. Replacement prostheses requested for cosmetic reasons or outside warranty will be chargeable. If You Need to Make a Warranty Claim
If you notice a problem with your implants or prosthesis:
1. Make contact with 21D as soon as possible
2. An assessment appointment will be arranged
3. A clinician will evaluate the issue
4. If the issue is covered, work will be completed at no cost
5. If not covered, we will explain your options clearly before any work proceeds
Prompt assessment helps protect implant health and long-term outcomes.
After Your Warranty Ends
Once your warranty period ends, repairs, adjustments and replacement components become chargeable.
Typical replacement costs include:
- Replacement PMMA/veneer component only: £500
- Replacement of full titanium bar/framework and veneer: £2,500
These fees reflect the custom engineering, precision milling and technical work carried out by 21D Bioengineering.
A full explanation and written quotation will always be provided before any work is carried out.
