All-on-4 Full Arch Reconstruction Cost and Procedure
All-on-4 is a full arch reconstruction method using four (or more) implants per arch to support a fixed prosthesis. Costs are typically per arch, including implants, connecting structure, and fixed prosthesis, and are affected by implant system, crown material, and need for bone grafting. Bilateral arches cost approximately twice that of a single arch. According to the National Health Insurance Administration, All-on-4 is self-paid and not covered by NHI. The procedure includes pre-treatment evaluation, implant surgery, osseointegration waiting period, and final prosthesis, often taking several months. The following is a neutral compilation of cost factors.
General treatment stages of All-on-4
All-on-4 usually requires several stages over several months; the actual timeline depends on individual bone quality and healing:
- Pre-treatment evaluation: imaging (e.g., CBCT), bone quality and occlusion assessment, treatment plan formulation.
- Implant surgery: placement of four (or more) implants in one arch, often with temporary fixed dentures on the same day.
- Osseointegration waiting: healing period of several months for implant-bone integration.
- Final dentures: fabrication and placement of permanent fixed dentures after stable integration, with occlusion adjustment.
Main factors affecting All-on-4 cost
Differences in single-arch quotes often stem from the following factors, which are differences in materials and treatment content, not quality ranking:
- Implant system and number, connection structure (e.g., angled abutments).
- Final denture material (acrylic resin, composite resin, or all-ceramic/zirconia, etc.).
- Need for bone grafting, use of digital guided surgery, and single or double arch.
Frequently Asked Questions
What is All-on-4?
All-on-4 is a full arch reconstruction method using four (or more) implants per arch to support a fixed prosthesis, commonly used for multiple missing teeth or edentulous arches. The number and position of implants and suitability must be assessed by a dentist based on bone quality, occlusion, and oral conditions. This is a neutral explanation, not a therapeutic claim.
What items are included in the All-on-4 cost?
Typically priced per arch, including four (or more) implants, connecting structure, and fixed prosthesis; depending on bone quality, may also include bone grafting or digital guided surgery fees. Bilateral arches cost approximately twice that of a single arch. Actual breakdown is subject to the clinic's written quote.
How is All-on-4 different from traditional full arch implants?
All-on-4 uses fewer implants (four per arch) to support a fixed prosthesis, while traditional methods may place more implants. The two differ in implant number, surgical extent, and cost structure. Suitability must be assessed by a dentist based on bone quality and occlusion.
What are the crown materials for All-on-4?
Common materials include acrylic resin, composite resin, and all-ceramic/zirconia. Material affects durability and cost; these are neutral specification differences, and selection should be discussed with the dentist.
Does NHI cover All-on-4?
All-on-4 is a self-paid treatment, not covered by NHI. Please refer to the clinic for detailed costs and breakdown.
How long does the All-on-4 full-arch rehabilitation treatment take?
The treatment usually includes pre-treatment evaluation and imaging, implant surgery, temporary dentures and osseointegration waiting period, and finally the final fixed dentures, often taking several months; the actual timeline depends on bone quality, need for bone grafting, and individual healing, as assessed by the physician in the treatment plan.
How long does All-on-4 last?
The lifespan is affected by oral hygiene, chewing habits, regular follow-ups, and individual bone condition; individual differences are large and cannot be generalized; evaluation requires long-term follow-up by a dentist. This site only compiles public information and is not medical advice.
What conditions must be met before undergoing All-on-4?
Suitability must be assessed by a dentist based on bone quality, periodontal and general health conditions; in some cases, periodontal issues or bone grafting may need to be addressed first; the actual assessment is based on the physician's treatment plan.
