What Is the All-on-4 Dental Implant Treatment?
All-on-4 is a full-arch tooth replacement treatment. Four titanium implant fixtures are placed into the jawbone to support a fixed prosthesis for the upper jaw, the lower jaw, or both.
Unlike removable dentures, the prosthesis is anchored in place, meaning that it does not rely on adhesives or suction. Whether provisional teeth can be placed on the same day as surgery depends on individual clinical findings and is not standard in every case.
How Does the All-on-4 Procedure Work?
Consultation and treatment planning
Your dentist carries out a full oral examination, reviews your dental and medical history, and assesses your bone volume and remaining teeth. Where clinically appropriate, 3D imaging is used to plan the precise position of each dental implant.
Implant placement surgery
Four fixtures are placed into the jawbone under local anaesthesia. Two are positioned vertically at the front of the arch; two are angled toward the back. Clinical studies indicate that this angled positioning can reduce the need for bone grafting in many cases, though this depends on individual anatomy and is not guaranteed.
Healing and osseointegration
Following surgery, osseointegration (the biological process by which the titanium fixture bonds with the surrounding jawbone) takes place over weeks to months. When osseointegration is successful, it provides the stable foundation the final prosthesis attaches to.
Final prosthesis
Once osseointegration is confirmed, the permanent restoration is fitted. The timeline varies between patients and is assessed at your review appointments.
Am I a Candidate for All-on-4?
You may be considered for All-on-4 if you have extensive tooth loss or a failing dentition, or if you have been finding removable dentures difficult to manage day to day.
Your dentist will assess the following at your consultation:
- Overall oral health and gum condition
- Bone volume and density available in your jaw
- Medical history and any conditions that may affect healing
- Smoking status, as research consistently shows that smoking is associated with a significantly higher risk of implant failure
- Whether preparatory treatment such as bone grafting is required before implant placement
Bone loss does not automatically rule you out, but it does need to be assessed. Suitability is determined case by case.
All-on-4 vs Removable Dentures: What Is the Difference?
Removable dentures sit on the gum tissue and can be prone to movement, particularly in the lower jaw.
All-on-4 implants provide a fixed foundation anchored directly into the jawbone, which for many patients translates to greater stability when eating and speaking.
That said, All-on-4 involves surgery and a healing period and is not appropriate for every patient. Your dentist will help you weigh up both options.
All-on-4 vs 3-on-6: What Is the Difference?
Both are implant-supported full-arch solutions, but they differ in structure.
- All-on-4 uses four implants to support one continuous full-arch prosthesis
- 3-on-6 uses six implants to support three separate bridge segments
Neither is universally superior. The right choice depends on your bone availability, remaining teeth, prosthetic goals, and your dentist’s clinical assessment.
How Much Do All-on-4 Dental Implants Cost in Singapore?
All-on-4 implant treatment in Singapore is quoted case by case at Garden Dental, following an individual assessment. Because every treatment plan is different, a fixed published price would not accurately reflect what your treatment involves or what it would cost.
During your consultation, your dentist will review your clinical situation and provide a personalised quotation based on your individual circumstances.
MediSave and CHAS Eligibility
Garden Dental is MediSave-accredited, and the clinic processes claims on your behalf.
According to the CPF Board, MediSave covers the surgical placement of dental implants at an operation limit of $1,120 per implant inserted, with a separate day-surgery consumables charge also claimable per session. How much you can claim depends on your MediSave balance, withdrawal limits, and the procedures performed.
CHAS may not cover the surgical placement of the implant fixture itself, though subsidies may apply to the implant crown and preparatory treatments such as tooth extractions. The clinic will advise on eligibility after your assessment.

Recovery After All-on-4 Surgery
Immediately after surgery (first few days)
Some swelling, bruising, and tenderness is normal. Your dentist will advise on pain management, suitable foods, and how to care for the surgical site.
Early healing (weeks to months)
Osseointegration takes place as the implant fixtures bond with the surrounding bone. You will attend review appointments so your dentist can monitor progress.
Final prosthesis fitting:
Once healing is confirmed, the permanent restoration is fitted. The overall timeline varies depending on your healing response, health, and treatment complexity.
Frequently Asked Questions
How much do All-on-4 dental implants cost in Singapore?
Garden Dental quotes All-on-4 on a case-by-case basis following an assessment. Please book a consultation to receive an individual quotation.
Can I use MediSave for All-on-4 dental implants?
MediSave covers the surgical placement of dental implants at MediSave-accredited clinics. Garden Dental is accredited and processes claims on your behalf. The claimable amount depends on the number of implants placed, your MediSave balance, and your withdrawal limits.
What is the difference between All-on-4 and 3-on-6?
All-on-4 uses four implants to support one full-arch prosthesis. 3-on-6 uses six implants to support three separate bridge segments. The appropriate approach depends on your bone availability, anatomy, and what your dentist recommends following a clinical review.
Is All-on-4 surgery painful?
The procedure is carried out under local anaesthesia. Some post-operative soreness and swelling is common and is typically manageable with the pain relief your dentist recommends.
How long do All-on-4 implants last?
Titanium implant fixtures are intended to be a lasting solution, though longevity varies between patients and depends on oral hygiene, bone health, and regular dental reviews. The prosthetic restoration may also require attention over time.
Am I still a candidate if I have bone loss?
Bone loss does not automatically disqualify you. Your dentist will assess available bone and advise whether implant placement is possible as planned, or whether additional treatment such as bone grafting may be required first.
