All-on-4 implant in Chennai at Siaris helps replace missing teeth with fixed full-mouth teeth. Read the 2026 guide on cost, results, benefits, and treatment process.
By Siaris Dental | Advanced Implantology & Full-Arch Reconstruction, Chennai
Losing most or all of your teeth is not a rare event. It happens through years of untreated gum disease, through cascading decay, through trauma, through the cumulative toll of systemic conditions like diabetes. And for a long time, the answer was the same for everyone: removable dentures. Plates that move when you eat. Adhesive that wears off. A nightly ritual of removal and soaking that serves as a constant reminder of what’s been lost.
All-on-4 changed that equation entirely.
In 2026, All-on-4 implant treatment in Chennai has become the benchmark solution for full-arch tooth loss offering fixed, permanent teeth supported by just four strategically placed implants per jaw. At Siaris Dental, we perform All-on-4 procedures to international standards, with outcomes that consistently match what patients see in before-and-after results from leading implant centres globally.
This guide covers everything: what All-on-4 actually is, who it’s right for, what it costs in Chennai in 2026, and what results are realistically achievable.
What Is All-on-4?
All-on-4 is a full-arch dental implant technique in which an entire arch of teeth upper, lower, or both is supported by exactly four implants. The concept was developed and clinically validated by Nobel Biocare and implant surgeon Paulo Maló, and it has accumulated over two decades of peer-reviewed outcome data, making it one of the most thoroughly evidenced procedures in modern implant dentistry.
The key innovation is the angulation of the posterior implants. Rather than placing all four implants vertically, the two back implants are tilted at 30 to 45 degrees. This angulation achieves two critical outcomes: it maximises contact with available bone anchoring into denser bone at the front of the jaw and it avoids anatomical structures that limit implant placement in fully edentulous patients, specifically the maxillary sinus in the upper jaw and the inferior alveolar nerve in the lower.
The result is a fixed prosthetic arch, a full set of teeth that can be loaded immediately in many cases. Patients who arrive at Siaris Dental in the morning with failing or missing teeth can, in qualifying cases, leave the same day with a temporary fixed bridge in place. The permanent prosthesis is delivered after full osseointegration, typically at the three-to-six-month mark.
This is not a removable denture. It does not come out at night. It does not require adhesive. It is fixed to implants anchored in your jawbone, and it functions and feels like natural teeth.
Who Is All-on-4 For?
All-on-4 was specifically designed to address the clinical realities of full or near-full tooth loss. The typical patient profile at Siaris Dental includes:
Patients with complete edentulism. Those who have lost all teeth in one or both arches and are currently wearing full dentures or avoiding treatment altogether. All-on-4 converts a denture situation into a fixed, permanent solution.
Patients with failing dentitions. Multiple teeth in end-stage decay, multiple failing bridges or crowns, and several teeth requiring extraction. Rather than attempting to save unsalvageable teeth one at a time, a full-arch clearance and All-on-4 reconstruction offers a definitive, long-lasting result.
Patients who cannot tolerate dentures. Gag reflex, poor denture retention due to bone resorption, chronic sore spots, or the psychological impact of removable teeth are legitimate and common reasons patients seek a fixed alternative, and All-on-4 reliably delivers it.
Patients with moderate bone loss. One of All-on-4’s most significant clinical advantages is its ability to work in jaws with reduced bone volume. The angulated posterior implants navigate around areas of bone loss and utilise denser anterior bone often eliminating the need for bone grafting that conventional implants would require. This makes it viable for patients who have been told elsewhere that they “don’t have enough bone” for implants.
Age is not a limiting factor. Patients in their 60s, 70s, and 80s are among the most motivated and most satisfied All-on-4 recipients at Siaris Dental. What matters is overall health status, not a number on a birth certificate.
Contraindications are relatively few: uncontrolled diabetes, active smoking (which significantly impairs osseointegration), ongoing chemotherapy or radiation to the head and neck, and severe uncontrolled osteoporosis. A thorough medical and dental assessment at Siaris determines individual suitability.
All-on-4 vs Traditional Full-Arch Implants
Patients often ask how All-on-4 compares to conventional full-arch implant approaches, typically All-on-6, or individual implants for each missing tooth.
All-on-4 vs All-on-6: All-on-6 uses six implants per arch rather than four, distributing load across more anchor points. For patients with adequate bone and budget, All-on-6 offers a slightly more robust foundation particularly for full-zirconia permanent bridges. All-on-4 remains the preferred approach when bone volume is reduced or when cost is a significant factor, and its long-term survival rates are clinically comparable to All-on-6 in appropriate candidates.
All-on-4 vs Individual Implants: Replacing each missing tooth with its own implant would require 10 to 14 implants per arch, multiple surgeries, considerably more healing time, significantly higher cost, and sufficient bone at each individual site. All-on-4 achieves comparable function and aesthetics with four implants, one surgery, and often immediate provisional teeth making it the superior choice for full-arch reconstruction in virtually every measurable dimension.
All-on-4 vs Conventional Full Dentures: The comparison is not close. Dentures sit on gum tissue, move during function, require adhesive, must be removed nightly, and do nothing to prevent the progressive bone resorption that occurs after tooth loss. All-on-4 implants stimulate bone, provide fixed function, require no adhesive or nightly removal, and restore confidence in eating and social interaction that dentures cannot replicate.
All-on-4 Cost in Chennai 2026
The cost of All-on-4 implant in Chennai in 2026 varies based on the number of arches treated, implant brand, prosthetic material, and whether preparatory procedures (extractions, bone management) are required.
All-on-4 Cost Breakdown at Siaris Dental:
| Component | Cost Range |
| CBCT scan and digital planning | ₹4,000 – ₹6,000 |
| All-on-4 (single arch) Nobel Biocare implants + provisional bridge | ₹2,80,000 – ₹4,00,000 |
| All-on-4 (single arch) Osstem implants + provisional bridge | ₹2,00,000 – ₹2,80,000 |
| Permanent full-arch zirconia bridge (per arch) | ₹80,000 – ₹1,50,000 |
| All-on-4 (both arches, complete) Nobel Biocare | ₹5,50,000 – ₹8,00,000 |
| All-on-4 (both arches, complete) Osstem | ₹3,80,000 – ₹5,50,000 |
| Extractions (if required, per tooth) | ₹800 – ₹2,500 |
Important: These figures include implants, surgical placement, and provisional prosthetics. The permanent bridge is a separate cost delivered at the three-to-six-month mark after osseointegration is confirmed.
For context, All-on-4 treatment for both arches with premium implants at comparable private clinics in the UK or Australia costs ₹15,00,000 – ₹25,00,000 or more. Chennai’s combination of internationally trained clinicians, premium materials, and significantly lower overheads makes it one of the most sought-after destinations for dental tourism in Asia and Siaris Dental’s all on 4 implant Chennai outcomes are consistently at par with international benchmarks.
Payment options: Siaris Dental offers zero-cost EMI on credit cards, NBFC-based financing up to 24 months, and phased billing aligned with treatment milestones. No patient should delay life-changing treatment purely for financial reasons our patient services team will find a workable path.
All-on-4 Procedure Timeline at Siaris Dental
Consultation and diagnostics (Week 1): A comprehensive examination, CBCT scan, and digital treatment planning session. Digital planning software allows the implantologist to virtually place each implant on your scan data before a single incision is made confirming position, angulation, and prosthetic design in advance.
Surgical day (Day of procedure): Under IV sedation or local anaesthesia, remaining failing teeth are extracted, implants are placed, and a provisional fixed bridge is attached. Most patients are in the chair for three to five hours. They leave with fixed teeth.
Healing phase (Months 1–3): The provisional bridge is worn during osseointegration. Patients maintain a soft diet. The implants are integrating with the bone; the provisional teeth look and function adequately but are not the final result.
Final prosthetics (Months 3–6): Once osseointegration is confirmed via clinical stability testing and follow-up imaging impressions (digital or physical) are taken for the permanent bridge. Full-arch zirconia bridges are fabricated at our partner dental laboratory and delivered in a fit and finish appointment.
Total treatment time: Four to six months from first appointment to permanent teeth, in most cases.
Before and After: What the Transformation Looks Like
Consider a 61-year-old patient, a retired government officer from Chennai who presented at Siaris Dental with 14 remaining upper teeth, all in advanced decay or heavily compromised by bone loss, and a lower jaw with only six teeth remaining. He had been avoiding eating out for two years, declining invitations that involved food, and was wearing a poorly fitting lower partial denture that he described as “useless.”
Preoperative CBCT revealed moderate bone resorption in both arches but sufficient anterior bone volume for All-on-4 in both jaws without grafting. Eight remaining upper teeth required extraction on the day of surgery; the remaining lower teeth were extracted and the lower arch treated simultaneously.
He left the clinic the same evening with fixed provisional bridges in both arches. Three days later, for the first time in years, he ate a full meal without pain, movement, or embarrassment. At the five-month mark, his permanent full-zirconia bridges were delivered 28 prosthetic teeth, upper and lower, fixed, white, properly proportioned to his face.
At his six-month review, he brought his wife. She said the change was not just in his teeth. It was in how he carried himself.
That is what All-on-4 implant outcomes in Chennai look like when treatment is planned and executed with precision. Not just functional restoration, full rehabilitation of confidence and quality of life.
Siaris Dental’s All-on-4 Expertise
All-on-4 is not a procedure that benefits from a learning curve. The angulation of posterior implants, the management of immediate loading forces, the design of the provisional bridge, and the transition to the permanent prosthesis all demand a level of implantological expertise and prosthetic planning that separates specialist centres from general dental practices offering the treatment at a discount.
At Siaris Dental, our All-on-4 outcomes are built on several non-negotiable foundations:
Specialist implantologist. Our lead implantologist has formal training in full-arch reconstruction and maintains active participation in international implant dentistry programmes. Every All-on-4 case is planned and executed by a clinician who performs this procedure regularly, not occasionally.
Nobel Biocare and Osstem certified. Siaris Dental is a certified provider for both Nobel Biocare and Osstem implant systems, the two most clinically validated platforms for All-on-4 treatment globally. Certification is not cosmetic; it reflects training, case volume, and outcome monitoring requirements set by the manufacturer.
In-house CBCT and digital planning. Every All-on-4 patient at Siaris receives a full CBCT scan interpreted by our own implantologist using digital planning software. The prosthetic outcome is designed before the surgery begins so the bridge that is fitted on surgical day reflects a plan, not an improvisation.
In-house provisional fabrication. Our on-site dental laboratory means provisional bridges can be made on the day of surgery in many cases, without outsourcing delays. Same-day teeth, done properly.
Structured follow-up. All-on-4 patients at Siaris are enrolled in a dedicated follow-up programme that reviews at one week, one month, three months, six months, and annually thereafter. Long-term implant success depends as much on monitoring as on the surgery itself.
Frequently Asked Questions
Q1: How long do All-on-4 implants last? The titanium implants, once fully integrated, can last a lifetime with appropriate maintenance. Long-term studies tracking All-on-4 patients over 10 years show cumulative implant survival rates above 94%. The prosthetic bridge the teeth themselves has a typical lifespan of 15 to 20 years for zirconia, after which it may require refurbishment or replacement. Annual reviews and professional maintenance significantly extend prosthetic longevity.
Q2: Will I be without teeth at any point during treatment? For the vast majority of patients undergoing All-on-4 at Siaris Dental, the answer is no. Provisional fixed bridges are placed on the day of surgery, so patients leave the clinic with fixed teeth. There is no period of wearing a removable denture between extraction and implant placement, which is a common concern and a genuine advantage of the All-on-4 immediate-load protocol.
Q3: Can All-on-4 fail? What are the risks? Like any implant procedure, All-on-4 carries a small risk of implant non-integration where the titanium post fails to bond with the bone. This occurs in roughly 2 to 5% of implants placed, with higher rates in smokers and uncontrolled diabetics. If an individual implant fails, it can typically be replaced without compromising the entire arch. Choosing a certified implant system, an experienced clinician, and following post-surgical protocols substantially mitigates this risk.
Q4: What can I eat after All-on-4? During the healing phase the first three months a soft diet is required to protect the provisional bridge and the integrating implants. Soft rice, yogurt, cooked vegetables, eggs, fish, and soups are all appropriate. Hard, crunchy, or chewy foods (raw vegetables, nuts, tough meat) are avoided during this period. Once the permanent bridge is delivered and integration confirmed, most patients can return to eating virtually anything including foods they haven’t been able to eat in years.
Q5: Is All-on-4 the same as “teeth in a day”? “Teeth in a day” refers to the immediate loading protocol used in All-on-4 placing provisional fixed teeth on the day of implant surgery. All-on-4 at Siaris Dental uses this protocol for eligible patients, meaning yes, you can have fixed teeth placed in a single surgical appointment. However, these are provisional teeth. The final, permanent zirconia bridge is delivered three to six months later, after osseointegration is confirmed. “Teeth in a day” is accurate for the provisional phase; the complete treatment still spans several months.
