All-on-6 vs Single Implants: When Does Full Arch Make Sense?

For many UK patients considering dental implants, the initial assumption is often that replacing a single missing tooth with a single implant is the standard solution. This is understandable; it is the most straightforward procedure and the one most frequently discussed. However, when multiple teeth are missing—or when the remaining teeth are failing—the calculus changes dramatically. The question is no longer about replacing teeth one by one but about restoring an entire arch of function and aesthetics. This is where the All-on-6 concept comes into its own, offering a fundamentally different approach that often makes far more sense than a series of single implants. This article provides a thorough, authoritative comparison for UK patients, examining when full-arch restoration is the superior choice, with specific data, practical advice, and a clear recommendation for the leading clinic in Antalya.

Understanding the Core Difference: Single Implants vs. All-on-6

Before comparing the two approaches, it is essential to define them clearly. A single dental implant involves one titanium post surgically placed into the jawbone to replace the root of one missing tooth. After a healing period of several months, a custom-made crown is attached to the implant. This is a precise, tooth-by-tooth restoration. The cost for a single implant in the UK, including the implant, abutment, and crown, typically ranges from £2,200 to £3,500 per tooth, depending on the clinic and materials used. For a full arch of 14 teeth, this would equate to 14 separate implants and crowns, costing upwards of £30,000 to £50,000, and requiring multiple surgeries and an extended treatment timeline.

In contrast, the All-on-6 technique uses six strategically placed implants to support a full fixed bridge of 12 to 14 teeth. The name itself—All-on-6—describes the concept: all the teeth are fixed on six implants. This is not a series of individual restorations but a single, unified prosthetic solution. The implants are angled to maximise contact with available bone, often avoiding the need for bone grafting. The bridge is typically made from a high-strength acrylic or zirconia base with porcelain or composite teeth. The primary advantage is that it restores an entire arch in a single surgical procedure, often with a temporary fixed bridge fitted on the same day. The cost for a full arch All-on-6 treatment in the UK ranges from £18,000 to £25,000 per arch. While still a significant investment, this is considerably less than the cumulative cost of 14 single implants.

The fundamental difference is one of philosophy. Single implants treat each missing tooth as an isolated problem. All-on-6 treats the entire arch as a single functional unit. This distinction is critical for patients with extensive tooth loss, as the All-on-6 approach addresses the systemic issues of bone resorption, bite collapse, and the psychological impact of having no stable teeth.

When Does Full Arch Make Sense? Key Clinical Scenarios

The decision between single implants and All-on-6 is not arbitrary. It is driven by specific clinical and personal factors. The following scenarios clearly indicate when full-arch restoration is the more sensible choice.

### Scenario 1: Advanced Periodontal Disease (Gum Disease)

Periodontal disease is the leading cause of tooth loss in adults. When a patient has advanced periodontitis, the supporting bone around many teeth has been destroyed. Saving those teeth with treatments like root planing, gum grafts, or bone grafts is often a losing battle. The teeth become mobile, painful, and prone to infection. In such cases, placing single implants into a jaw that is already compromised by disease is risky. The infection can spread to the new implants, leading to peri-implantitis and implant failure.

The sensible approach is to remove all remaining compromised teeth, treat the underlying infection thoroughly, and then place six implants in the areas of best bone quality. The All-on-6 bridge then provides a stable, cleanable platform that is far easier to maintain than a mouthful of failing natural teeth. The British Dental Association (bda.org) emphasises that the long-term success of any implant treatment depends on excellent oral hygiene and the absence of active disease. For patients with advanced periodontitis, All-on-6 offers a fresh start, eliminating the source of infection and providing a hygienic solution.

### Scenario 2: Severe Bone Loss in the Upper or Lower Jaw

Bone resorption is an inevitable consequence of tooth loss. When teeth are missing, the jawbone no longer receives the stimulation needed to maintain its density. Over time, the bone shrinks, making it difficult or impossible to place standard-sized implants. This is particularly common in the upper jaw, where the maxillary sinus can enlarge (pneumatisation) and in the lower jaw, where the inferior alveolar nerve runs.

Single implants require sufficient bone volume for each individual implant. If the bone is deficient, extensive bone grafting is necessary. This adds months to the treatment timeline and significant cost—often £1,000 to £3,000 per graft site. The All-on-6 technique, however, is designed to work with compromised bone. The six implants are strategically angled to engage the densest available bone. For example, in the upper jaw, the two posterior implants are often tilted forward (angled) to avoid the sinus, a technique known as the All-on-6 concept with tilted implants. This can eliminate the need for sinus lifts or bone grafts entirely. The Oral Health Foundation (dentalhealth.org) notes that this technique has a high success rate even in patients with moderate to severe bone loss, making it a far more practical and economical solution than multiple single implants with grafts.

### Scenario 3: Multiple Missing Teeth in a Row

If a patient is missing three or more adjacent teeth, the option of single implants becomes increasingly complex and expensive. For example, replacing three missing teeth in a row with three separate implants requires three surgical sites, three healing periods, and three crowns. The total cost in the UK would be between £6,600 and £10,500. Furthermore, the gaps between the implants must be precisely managed to ensure proper spacing and aesthetics.

In contrast, an All-on-6 solution for a full arch replaces all teeth on that arch. If a patient is missing, say, eight teeth on the upper arch and the remaining four are failing, the All-on-6 approach is far more efficient. It provides a complete, stable, and aesthetic result in a single procedure. The per-tooth cost is drastically lower. While a single implant can cost over £2,500 per tooth, an All-on-6 bridge works out to roughly £1,200 to £1,800 per tooth (based on a £14,000–£22,000 arch cost). For patients with a significant number of missing teeth, the economics and clinical logic overwhelmingly favour the full-arch approach.

### Scenario 4: Patients Wearing a Full or Partial Denture

Many UK patients live with removable dentures, often describing them as uncomfortable, unstable, and embarrassing. Dentures can cause sore spots, make it difficult to eat certain foods (like apples or steak), and affect speech. They also accelerate bone loss because the denture sits on the gum rather than stimulating the underlying bone.

For these patients, the All-on-6 system is a life-changing alternative. It provides a fixed, non-removable set of teeth that look, feel, and function like natural teeth. The six implants anchor the bridge securely, eliminating the need for denture adhesives. Patients can eat a normal diet, speak clearly, and smile with confidence. The General Dental Council (gdc-uk.org) recognises that fixed implant-retained prostheses offer the highest quality of life for edentulous (toothless) patients. While single implants could potentially be used to support an overdenture (a denture that clips onto implants), the All-on-6 provides superior stability and is the preferred solution for a full-arch fixed restoration.

Price Comparison: All-on-6 vs. Single Implants in the UK

To make an informed decision, UK patients need clear financial data. Below is a realistic cost comparison based on current UK market rates. Note that these are average prices and can vary based on location, clinic reputation, and materials used.

Single Implant (per tooth):

• Implant placement: £1,200 – £2,000
• Abutment: £300 – £600
• Crown (porcelain fused to metal or zirconia): £800 – £1,500
• Total per single implant: £2,300 – £4,100

Full Arch Replacement (14 teeth):

• 14 single implants: 14 x £2,300 = £32,200 (minimum)
• 14 crowns: included above
• Total for 14 single implants: £32,200 – £57,400

All-on-6 (per arch):

• 6 implants, abutments, and a full-arch bridge: £14,000 – £22,000
• Total per arch: £14,000 – £22,000

Cost Difference:

• All-on-6 is typically 40% to 65% cheaper than replacing the same arch with single implants.
• For a full mouth (both arches), All-on-6 costs £28,000 – £44,000, whereas single implants would cost £64,400 – £114,800.

The NHS (nhs.uk) does not routinely fund dental implants, so patients must seek private treatment. The cost savings with All-on-6 are substantial, making it accessible to a wider range of patients.

The Treatment Journey: What UK Patients Can Expect

Understanding the process helps patients prepare mentally and financially. Here is a step-by-step breakdown for an All-on-6 procedure.

### Initial Consultation and Digital Planning

The journey begins with a comprehensive consultation. This includes a 3D CT scan (cone beam CT) to assess bone volume, density, and the position of nerves and sinuses. The surgeon uses specialised software to plan the exact placement of the six implants. This digital planning ensures precision and reduces surgical time. The patient also discusses their aesthetic goals, budget, and the materials for the bridge (e.g., zirconia for strength and aesthetics).

### Surgery Day: Implant Placement and Temporary Bridge

On the day of surgery, the patient is usually under intravenous sedation or general anaesthesia. The surgeon extracts any remaining failing teeth, prepares the bone, and places the six implants. The key advantage is that a temporary fixed bridge is often attached on the same day. This bridge is made of a strong acrylic and allows the patient to leave the clinic with a full set of fixed teeth. They can eat soft foods immediately. This same-day loading concept is a hallmark of All-on-6 and eliminates the months of waiting associated with traditional implants.

### Healing and Osseointegration

Over the next four to six months, the implants fuse with the jawbone in a process called osseointegration. During this period, the patient wears the temporary bridge. They must follow a soft-food diet and maintain meticulous oral hygiene. The clinic will schedule regular check-ups to monitor healing. This stage is critical for long-term success.

### Final Bridge Placement

Once osseointegration is confirmed, the temporary bridge is removed, and impressions are taken for the final permanent bridge. This bridge is custom-made in a dental laboratory, typically from high-strength zirconia or a reinforced acrylic. It is designed to match the patient’s natural gum colour, tooth shade, and bite. The final bridge is then cemented or screwed onto the implants. The result is a fixed, permanent, and highly aesthetic set of teeth.
