If you have lost most or all of your teeth, or find removable dentures uncomfortable, a fixed implant-supported restoration may be worth discussing with your dentist.
All-on-4 is one approach to replacing a complete arch of teeth using four dental implants. For suitable patients, it can provide a fixed alternative to conventional removable dentures. However, treatment suitability, healing time and the choice of restoration vary from person to person.
For expats and international patients considering All-on-4 dental implants in Shanghai, understanding the complete treatment plan is especially important. This includes the costs, the difference between temporary and final teeth, and the appointments needed for follow-up care.
At Smile Dentistry Gubei, our team provides consultations in English, Chinese and Korean to help patients understand their implant treatment options.
What Are All-on-4 Dental Implants?
All-on-4 is a full-arch implant treatment concept in which four implants support a fixed restoration replacing the teeth in the upper or lower jaw.
Rather than placing an implant for every missing tooth, the implants are positioned to support a connected set of replacement teeth. In many treatment plans, the rear implants are angled to make use of available bone and avoid certain anatomical structures.
An important distinction is that one full arch is not the same as the whole mouth. Treatment for the upper jaw replaces one arch. Replacing teeth in both the upper and lower jaws involves two arches and a separate assessment of each.
Four implants are not automatically the best option for every patient. Depending on your bone condition, bite and restorative needs, your dentist may recommend a different number of implants or another treatment approach.

Who May Be Suitable for All-on-4?
All-on-4 may be considered for patients who:
- Have lost all or most teeth in one arch
- Have remaining teeth with a poor long-term prognosis
- Find conventional removable dentures unstable or uncomfortable
- Would like to explore a fixed alternative to dentures
Having several missing teeth does not automatically mean you need full-arch treatment. If healthy teeth can be preserved, other options may be more appropriate.
Before recommending treatment, your dentist will assess your oral health, available bone, bite, medical history and ability to maintain the restoration. Smoking, active gum disease and certain medical conditions may affect planning and healing.
How Much Does All-on-4 Cost in Shanghai?
The cost of All-on-4 treatment depends on the complete surgical and restorative plan, not just the number of implants.
Factors that may affect your quotation include:
- Whether one arch or both arches are treated
- The implant system selected
- The condition of the remaining teeth and jawbone
- Whether extractions or bone augmentation are required
- The design and materials of the temporary restoration
- The materials used for the final restoration
- Diagnostic imaging and laboratory work
- Follow-up appointments and maintenance arrangements
When comparing quotations, ask for a written breakdown of what is included.
| Item to confirm | Why it matters |
|---|---|
| One arch or two arches | Upper-jaw treatment alone is different from treatment for both jaws |
| Extractions and additional procedures | These may be quoted separately |
| Temporary teeth | A provisional restoration may be a separate treatment stage |
| Final restoration | Materials and construction can affect the overall cost |
| Follow-up care | Review visits, adjustments and maintenance should be clarified |
| Future repairs | Ask how replacement or repair of restorative components is handled |
At Smile Dentistry Gubei, an individual examination is needed before treatment options and costs can be confirmed.

The All-on-4 Treatment Process
Full-arch implant treatment usually involves several stages. The exact sequence depends on your clinical needs.
1. Consultation and Comprehensive Assessment
The first stage includes an oral examination and a discussion of your concerns, expectations and medical history.
Your dentist will assess:
- The condition of any remaining teeth
- Gum health and oral hygiene
- The available bone
- Your bite and jaw relationship
- Your current dentures, if applicable
- Your ability to clean and maintain a fixed restoration
Imaging, which may include a CBCT scan, helps the clinician evaluate the jawbone and nearby anatomical structures.
2. Treatment Planning
The surgical and restorative stages need to be planned together.
Your dentist will consider implant positions, the proposed tooth arrangement, bite function and how the restoration will be cleaned. The plan should also explain alternatives and whether any remaining teeth can be retained.
Before proceeding, you should understand:
- Why the proposed approach is recommended
- Whether extractions are needed
- Whether bone augmentation may be required
- Whether immediate temporary teeth are an option
- The expected treatment stages and appointments
- The costs, risks and ongoing maintenance needs
3. Implant Placement and Temporary Teeth
Implants are placed according to the agreed treatment plan. Extractions may be performed at the same appointment in some cases.
Selected patients may be able to receive a fixed temporary restoration on the day of surgery or shortly afterwards. This depends on factors including implant stability, bone condition and the clinician’s assessment.
Immediate temporary teeth are not suitable for everyone. If they are not appropriate, your dentist will explain other options for the healing period.
4. Healing and Review Appointments
After placement, the implants need time to integrate with the surrounding bone.
During this stage, follow-up appointments allow the dentist to review healing, check the restoration and make adjustments where needed. You may be advised to follow a modified diet and avoid placing excessive pressure on the temporary teeth.
Your treating team will provide individual instructions for cleaning, eating and postoperative care.
5. Final Restoration
Once healing and implant readiness have been assessed, the final restoration can be planned and fitted.
Its design considers appearance, speech, bite function and access for cleaning. Further appointments may be needed to check the fit and make adjustments.
A fixed restoration still requires daily cleaning and ongoing professional maintenance.
How Long Does All-on-4 Treatment Take?
All-on-4 treatment should be understood as a staged process rather than a single-day procedure.
| Treatment stage | What to expect |
|---|---|
| Assessment and planning | Examination, imaging and discussion of treatment options |
| Surgical stage | Implant placement and any planned additional procedures |
| Temporary restoration | May be fitted promptly in selected cases |
| Healing | Usually measured in months rather than days; timing varies |
| Final restoration | Fitted after the clinician confirms readiness |
| Maintenance | Continues throughout the life of the restoration |
Your dentist can provide a more meaningful timeline after examining you. Bone augmentation, medical considerations or changes during healing may extend the process.
Potential Benefits of All-on-4
A Fixed Alternative to Removable Dentures
The restoration is attached to implants rather than being removed by the patient each day. It may still need to be removed by a dental professional for certain maintenance or repair procedures.
Improved Stability
For suitable patients, implant support can reduce the movement associated with conventional removable dentures. This may improve comfort during speaking and eating.
Individually Planned Appearance
The shape, position and appearance of the replacement teeth can be planned around your facial features, speech and bite.
Fewer Implants Than Some Other Full-Arch Approaches
Using four implants may reduce the number of implant placements compared with certain alternative plans. However, fewer implants do not automatically mean lower overall risk, lower cost or a better result.
The most appropriate treatment is the one that fits your clinical needs.
Risks and Limitations to Discuss
All-on-4 involves surgery and long-term maintenance. It is important to understand the limitations as well as the potential benefits.
Possible concerns include failure of an implant to integrate, infection, inflammation around implants and wear or damage to restorative components. Changes to speech or eating may require an adjustment period.
A fixed restoration can also be challenging to clean without the right technique and tools.
Your dentist should explain the risks relevant to your case, available alternatives and the arrangements for managing complications.
Planning All-on-4 Treatment as an International Patient
If you live outside Shanghai, discuss your travel arrangements before starting treatment.
Questions to ask include:
- How many appointments and trips are likely?
- How long should I remain in Shanghai after surgery?
- When will the final restoration be fitted?
- Who should I contact if a problem develops after I return home?
- Can my treatment records be shared with a dentist near me?
- How will long-term reviews and maintenance be arranged?
Receiving temporary teeth during one visit does not remove the need for healing checks, final restorative treatment or future maintenance.
Avoid making travel plans based only on a promise of “teeth in one day”. Ask what that phrase means in your individual treatment plan.

Frequently Asked Questions
Can All-on-4 be completed in one day?
Some patients may receive fixed temporary teeth on the day of implant placement or shortly afterwards. This is not the same as completing the entire treatment. Healing, review appointments and the final restoration are still required.
Does All-on-4 replace the whole mouth?
One All-on-4 restoration replaces one arch, either the upper or lower teeth. Treatment for both jaws involves two arches, each requiring its own assessment and plan.
Will I need bone grafting?
Some patients may be treated without extensive bone grafting, but this cannot be assumed. Imaging and clinical assessment are needed to determine the available bone and the safest approach.
Is All-on-4 better than All-on-6?
Neither approach is universally better. The number of implants should be selected according to bone availability, bite forces, restorative design and other clinical factors.
How long do All-on-4 implants last?
Implants and their restorations can provide long-term function, but they are not guaranteed to last a lifetime. Daily cleaning, professional maintenance and management of risk factors are important. Restorative components may need repair or replacement.
Can I eat normally immediately after treatment?
Not necessarily. During healing, your dentist may recommend a modified diet to protect the implants and temporary restoration. Follow the instructions provided for your case.
Does dental insurance cover All-on-4?
Coverage depends on your policy. Full-arch implant treatment may be excluded, subject to limits or require preauthorisation. Direct billing availability does not guarantee coverage.
