Who Is Suitable for All-on-6 Dental Implants?
All-on-6 dental implants may be an option for adults who have lost most or all of their teeth and want a
fixed full-arch restoration. However, missing teeth alone do not determine suitability. Bone structure, gum
health, medical history, bite forces, smoking and the ability to maintain the restoration all need to be
considered.
Only a clinical examination and appropriate diagnostic imaging can confirm whether six implants are
suitable for a particular jaw.
What Is All-on-6 Treatment?
All-on-6 treatment uses six dental implants to support a complete fixed bridge in the upper or lower jaw.
The implants are positioned according to the available bone and the requirements of the planned
restoration.
Six implants can distribute support across a wider area when anatomy allows, but All-on-6 is not
automatically better than treatment using four implants. The most appropriate design depends on the
individual case.
Patients Who May Benefit from All-on-6
Treatment may be considered for people who:
• Have lost all teeth in one or both jaws
• Have several failing teeth that cannot be restored predictably
• Struggle with loose removable dentures
• Want replacement teeth that remain fixed during daily use
• Have sufficient bone for six implants or a suitable grafting plan
• Understand the need for surgery, healing and maintenance
• Can clean beneath a full-arch bridge every day
The objective is not simply to place six implants. The implants must be positioned safely and support a
bridge that functions correctly and can be maintained.
Bone Requirements for All-on-6
The dentist normally uses a CBCT scan to assess bone height, width and quality. The scan also helps
identify structures such as nerves and sinus spaces.
Patients with reduced bone may still have options, which can include changing implant positions, using a
different number of implants or performing bone grafting. The safest choice depends on anatomy and
restorative planning.
No decision should be made from a panoramic image or photographs alone when three-dimensional
information is clinically required.
Gum Health and Previous Gum Disease
Active gum disease should be controlled before implant placement. A previous history of periodontitis
does not necessarily prevent treatment, but it may increase long-term maintenance needs.
Patients need healthy, stable tissues and a realistic plan for professional follow-up. Removing damaged
teeth does not remove a patient’s susceptibility to inflammatory disease around implants.
Medical Conditions and Medicines
Many people with managed medical conditions can receive dental implants, but individual risk assessment
is essential. Relevant issues may include:
• Diabetes control
• Conditions affecting immune response or healing
• Previous radiotherapy to the jaw area
• Bleeding disorders or anticoagulant medication
• Medicines that affect bone metabolism
• Recent major surgery or serious illness
Patients should never stop prescribed medication without guidance from the relevant clinician.
Smoking and All-on-6 Treatment
Smoking and nicotine can interfere with healing and increase the risk of complications. Patients should
disclose cigarette, vaping and other nicotine use honestly.
Stopping smoking before and after surgery may improve the healing environment. The dental team can
explain how smoking affects individual suitability and long-term prognosis.
Teeth Grinding and Bite Problems
Clenching or grinding may overload the bridge and implant components. Severe bite forces do not always
rule out treatment, but they must be recognised and managed.
The plan may involve bite adjustment, restorative design changes, material selection and a protective
night guard.
Is Age a Barrier?
There is no single upper age limit for dental implants. General health, bone condition, healing capacity and
ability to maintain the restoration are more important than chronological age.
Implants are generally not placed until jaw growth is complete, so treatment is not normally intended for
younger patients who are still growing.
When Might Another Treatment Be Better?
All-on-6 may not be the most appropriate option when:
• Healthy teeth can be preserved with predictable treatment
• There is not enough bone to place six implants safely
• A four-implant design better suits the anatomy
• A removable implant-supported overdenture offers easier cleaning
• Surgery presents unacceptable medical risk
• The patient cannot maintain daily hygiene or follow-up care
A responsible consultation should include suitable alternatives rather than presenting All-on-6 as the only
solution.
What Happens During the Assessment?
An All-on-6 assessment may include:
1. Dental and medical history review
2. Examination of teeth, gums and bite
3. X-rays and three-dimensional CBCT imaging
4. Digital scans or impressions
5. Smile and facial assessment
6. Discussion of temporary and final teeth
7. Review of risks, alternatives, costs and timescale
Patients should understand whether extractions or grafting are proposed and whether immediate
temporary teeth are genuinely appropriate.
Questions to Ask at Your Consultation
• Why are six implants recommended in my case?
• Could four implants or another option be appropriate?
• Do I need bone grafting?
• Am I suitable for immediate temporary teeth?
• Which bridge material is proposed?
• How will I clean beneath the bridge?
• What maintenance and future costs should I expect?
• What happens if an implant does not integrate?
Find Out Whether All-on-6 Is Right for You
Suitability can only be determined after individual assessment. Agagsia Dental Clinic can examine your
oral health, review diagnostic imaging and explain whether All-on-6 dental implants or an alternative may
be appropriate.
