All on 4 Implant Treatment Singapore

All on 4 Implant Treatments are a fixed full-arch solution that replaces an entire row of missing teeth with four implants and a same-day temporary bridge, commonly referred to as Teeth in a Day. The angled placement of the rear implants maximises contact with existing bone, making the procedure suitable for many patients without additional bone grafting. Casa Dental performs this treatment across nine locations in Singapore, with costs starting from SGD $20,000 + GST and partial MediSave coverage available.

What Is All-on-4/All-on-X (Teeth in a Day)?

All-on-4 dental implants in Singapore, also referred to as Pro-Arch, All-on-X, or Teeth in a Day, replace an entire row of missing teeth using four strategically placed titanium implants and a fixed prosthetic bridge. The treatment is designed for patients with complete or near-complete tooth loss in one or both jaws. A temporary fixed bridge is placed on the same day as surgery, allowing patients to leave the clinic with functional teeth immediately following the procedure.

How the Placement Works

Two implants are positioned vertically at the front of the jaw and two are angled toward the back. The angled rear implants maximise contact with existing bone, which means many patients do not require bone grafting even where some bone loss has already occurred. Each arch takes approximately 2 to 2.5 hours to complete.

How Does Pro-Arch/All-on-4/All-on-X Work?

The All-on-Four technique involves placing four titanium implants into the jawbone at strategic angles. Two implants are placed vertically at the front of the jaw, and two are angled towards the back. This angled placement maximises contact with existing bone, often eliminating the need for bone grafting even in patients with some degree of bone loss.

Once the implants are securely in place, the dentist attaches a custom-made fixed bridge, restoring the entire row of teeth. The whole surgical procedure typically takes approximately 2 to 2.5 hours per arch.

Is Full-Arch Treatment Right for You?

Full arch dental implants are beneficial for individuals with significant tooth loss, but it may not be suitable for every patient. While the technique is designed to maximise efficiency and minimise the need for bone grafts, certain factors still determine whether someone is an ideal candidate.

Who Is Suitable

A Pro Arch implant is most suitable for individuals who:

For patients who have worn dentures for a long time, bone resorption is common and affects where implants can be safely placed. Your dentist will use 3D imaging to assess the extent and distribution of bone loss before planning implant positions. Two patients receiving All-on-4 may end up with different configurations depending on what bone is available.

Who May Not Be Suitable

Full arch implant treatment requires thorough screening. Patients with the following conditions may not be suitable, or may require additional assessment and medical clearance before proceeding:

Your dentist will review your full medical history and imaging at your consultation. Some of the above conditions may be manageable with treatment or staging rather than being absolute exclusions.

If you are only missing a single tooth or a few teeth, you may want to explore our other dental implants page to find the most suitable solution for your needs.

What If I Don’t Have Enough Bone for All-on-4?

Some patients have bone loss significant enough that standard All-on-4 placement is not straightforward. In these cases, your dentist may recommend:

  • Bone grafting to rebuild bone structure before implant placement
  • Zygomatic implants anchored in the cheekbone rather than the jawbone, suitable for patients with severe upper jaw bone loss
  • Tubero-Pterygoid implants placed in the pterygoid bone at the back of the upper jaw, another option for patients with limited upper jaw bone


These approaches are assessed at your consultation based on 3D imaging. Not all patients with bone loss require them.

What Our Dentists Say About All on X

Read real insights from our dentists on dental implants, including healing timelines, treatment planning, and what patients should know before getting started.

Recovery and Aftercare

Most patients return to normal activities within a few days. Full osseointegration typically takes 3–6 months.

What to Expect After Surgery

In the days following the procedure, it is normal to experience:

  • Swelling and discomfort at the implant sites
  • Some bleeding at the implant area
  • A temporary adjustment period for speech as you adapt to the bridge
  • Mild sore throat
  • Jaw discomfort or stiffness

These side effects typically resolve within one to two weeks and can be managed with medication prescribed by your dentist.

Follow-Up Appointment Schedule

  • 1 week — Check that the bridge is clean and healing is progressing normally
  • 2 weeks — Bridge check and stitch removal
  • 8 weeks — Full healing assessment
  • 6 months — Final bridge fitted once osseointegration is confirmed

Bite balance can shift gradually due to bone remodelling, opposing tooth changes, or habits like grinding. Follow-up appointments allow your dentist to detect and correct uneven load before it becomes a problem.

Oral Hygiene

Brush twice daily with a soft-bristled toothbrush and non-abrasive toothpaste. Use interdental brushes or a water flosser to clean around the implants. An antibacterial mouthwash is recommended to reduce infection risk.

Dietary Guidelines

Stick to soft foods immediately after surgery. Gradually reintroduce normal foods as healing progresses. Avoid hard or sticky foods that could strain the prosthesis.

Lifestyle Factors

Smoking significantly increases the risk of implant failure by impeding healing. Patients are strongly advised to quit smoking before and after the procedure.

Frequently Asked Questions

How successful are All-on-4 dental implants long-term?

All-on-4 dental implants have a success rate of approximately 95% when placed by experienced implant dentists and maintained with good oral hygiene. The titanium implants are engineered for long-term stability, and most patients experience no complications with proper aftercare.

What is peri-implantitis and how do I avoid it?

Peri-implantitis is an inflammatory infection affecting the tissue surrounding the implant. Warning signs include bleeding or pus, fever, throbbing pain, redness and swelling in the gums, bad breath, difficulty chewing, and the implant feeling loose. It is prevented through diligent oral hygiene, regular dental check-ups, and avoiding smoking.

What happens if one of my All-on-4 implants fails?

Implant failure is uncommon but can occur due to poor osseointegration, infection, or excessive load. If an implant fails, the affected fixture is removed, the site is allowed to heal, and re-implantation is assessed once the area has recovered. Attending all follow-up appointments, maintaining good oral hygiene, and avoiding smoking are the most effective preventive measures. If you notice persistent pain, unusual swelling, or implant mobility between appointments, contact your Casa Dental clinic promptly.

What should I ask a dental clinic before committing to All-on-4 treatment?

Before proceeding, ask about the dentist’s experience with full-arch implant cases, what materials are used for the prosthesis, and whether the clinic has an in-house laboratory. It’s also worth confirming what is included in the quoted price — specifically whether consultations, the temporary bridge, and follow-up appointments are covered.

Do All-on-4 implants and the prosthesis last the same amount of time?

The titanium implants themselves can last 20 years or more with proper care. The prosthesis (the bridge of replacement teeth) is a separate matter; depending on the material, it may need adjustment or replacement every 10 to 15 years due to normal wear. Your dentist will advise on the expected lifespan of your specific restoration during consultation.

Are All-on-4 dental implants reversible?

Once the implants have integrated with the jawbone, they cannot be removed without surgery. While removal is technically possible, it requires a clinical procedure and full replanning. This is why a thorough consultation and 3D assessment beforehand are essential

All-on-4 is a long-term commitment, not a trial solution.

Can I have All-on-4 on just one arch?

Yes. All-on-4 can be placed on the upper arch, the lower arch, or both. Your doctor will evaluate your specific situation and recommend whether treating one or both arches is most appropriate for your case.

What if I'm missing several teeth but not a full arch. Is All-on-4 still an option?

 All-on-4 is designed for patients with complete or near-complete tooth loss in one jaw. If you are missing several teeth but retain healthy remaining teeth, an implant-supported bridge using two or more implants may be a more appropriate solution. Your dentist will assess the number and position of missing teeth, along with your bone condition, to determine the most suitable approach.

Can All-on-4 implants develop cavities?

No. The bridge and implants are not made of natural tooth structure, so they cannot develop cavities. However, the gums and bone surrounding the implants can still become inflamed if plaque is allowed to accumulate, which is why daily cleaning around the bridge remains essential.

Are All-on-4 implants removable?

No. All-on-4 implants are permanently fixed into the jawbone and cannot be removed. Unlike traditional dentures, there is no need to take them out for cleaning, soaking, or sleeping. They are maintained exactly like natural teeth — brushing, interdental cleaning, and regular dental check-ups.

Is All-on-4 worth it?

For patients with significant tooth loss or failing dentition, All-on-4 is widely regarded as one of the most effective long-term solutions available. It restores full chewing function, prevents ongoing jawbone loss, and eliminates the daily inconvenience of removable dentures — all in a single surgical session. The upfront investment is higher than dentures, but when weighed against decades of durability, improved quality of life, and the reduced need for ongoing replacements or adjustments, most patients find the outcome justifies the cost. The best way to assess whether it is right for your specific situation is through a consultation and 3D imaging at one of our nine clinics.

What is the difference between All-on-4 and All-on-6?

All-on-4 uses four implants per arch, while All-on-6 uses six. The additional implants distribute bite forces across a wider base, which may be recommended for patients with higher occlusal load or specific bone geometry. Casa Dental’s Pro-Arch system supports both configurations. Your dentist will recommend the appropriate option based on your bone structure and bite assessed during consultation.
